🌡️ How It Works: The Condensation Principle

The Dantherm CDP70 operates using proven refrigeration technology to remove moisture from the air:

The Dehumidification Cycle

1. Air Intake 🌬️
Humid air from the pool room is drawn into the unit by powerful 900m³/hr fans through the washable foam pre-filter.

2. Cooling & Condensation ❄️
Air passes over the cold evaporator coil where it’s cooled below dew point. Water vapor condenses into liquid water which collects in the drip tray and drains away (up to 69 litres per day).

3. Reheating 🔥
Now-dry air passes through the hot condenser coil where it’s warmed by the heat from the refrigeration cycle plus compressor energy. Air exits approximately 5°C warmer than it entered.

4. Return to Room ♻️
Warm, dry air is returned to the pool space, simultaneously reducing humidity AND adding heat (3.24kW), which reduces supplementary heating requirements.

Intelligent Features

🧊 Automatic Defrost System The CDP70 continuously monitors evaporator temperature. When ice formation is detected:

• Fans stop automatically
• Solenoid valve opens to route hot gas through evaporator
• Ice melts quickly without manual intervention
• Normal operation resumes when coil temperature is optimal

🛡️ Safety Protection

• High-pressure cutout: Prevents compressor damage if airflow restricted
• Low-pressure monitoring: Detects refrigerant leaks early (LPCO pre-warning system)
• Thermal overload: Compressor shuts down if temperature exceeds 55°C
• Anti-short-cycle timer: Minimum 6 minutes between compressor starts (max 10 starts/hour)

📊 Intelligent Control

• Hourly humidity sampling: T-models check humidity once per hour when in standby
• Only runs when needed: Compressor and fans activate only when humidity exceeds setpoint
• Hysteresis control: ±2% RH prevents constant cycling
• Temperature compensation: Adjusts performance based on ambient temperature (10-36°C range)

💚 Environmental Performance & Water Quality

Chlorinated Pool Compatibility

The CDP70 is specifically engineered for harsh chlorinated pool environments. All wetted surfaces feature protective coatings:

✅ Epoxy-Coated Heat Exchangers
Evaporator and condenser coils have factory-applied epoxy coating resistant to chlorine vapor, chloramines, and other pool chemicals.

✅ Powder-Coated Metal Panels
All steel components are powder-coated BEFORE assembly, providing superior corrosion protection compared to post-assembly painting.

✅ Stainless Steel Fasteners
Critical fixings use corrosion-resistant materials for long service life.

Water Quality Requirements

To ensure warranty validity and optimal performance, maintain these water chemistry parameters:

For Pools with Chemical Addition:

Parameter	Required Range
Free Chlorine	1.0 – 2.0 ppm
Combined Chlorine	Max. 1/3 of free chlorine
pH	7.2 – 7.6
Total Alkalinity	80 – 150 ppm
Calcium Hardness	250 – 450 ppm
Total Dissolved Solids (TDS)	<2,000 ppm
Sulphates	<360 ppm

For Salt Water Pools (Electrolytic Chlorine Generation):

Parameter	Required Range
Salt (NaCl)	<30,000 ppm (3%)
Total Dissolved Solids (TDS)	<5,500 ppm
pH	7.2 – 7.6
Total Alkalinity	80 – 150 ppm
Calcium Hardness	250 – 450 ppm
Sulphates	<360 ppm

⚠️ Important: Poor water chemistry will void warranty and can destroy the unit in weeks. Use the Langelier Saturation Index to verify balanced water chemistry. Contact Dantherm support if you need assistance calculating LSI.

Refrigerant Environmental Impact

R407C Refrigerant:

• Charge: 1.2 kg per unit
• Global Warming Potential (GWP): 1774
• Ozone Depletion Potential (ODP): Zero
• CO₂ Equivalent: 2.13 tonnes CO₂e over refrigerant lifetime

The CDP70 uses a moderate-GWP refrigerant that is more environmentally friendly than older R22 systems (GWP 1810) but not as low as newer R32 (GWP 675) or R290 (GWP 3) options. However, R407C offers excellent performance in pool dehumidification applications and complies with current F-Gas regulations.

End of Life: Units must be professionally decommissioned with refrigerant recovery by certified technicians. Compressor oil contains refrigerant and requires proper disposal per local regulations.

❓ Frequently Asked Questions

General Questions

Q: What size pool is the CDP70 suitable for?
A: The CDP70 is designed for pools with water surface areas of 50-70m² in typical conditions (water 28-30°C, air 30-32°C, moderate bather load). For pools at the upper end of this range or with heavy use, consider running the unit longer hours or adding supplementary dehumidification. Pools over 70m² may require multiple units or a larger capacity system.

Q: Can I use this in a domestic home pool?
A: While the CDP70 is marketed for commercial applications, it works excellently in large residential pools (8m × 4m and larger). However, the high extraction rate may be oversized for small domestic pools—consider the CDP40 or CDP50 for pools under 40m². The professional-grade construction ensures long service life even with daily residential use.

Q: What’s the difference between CDP70 and CDP70T models?
A: The CDP70 is a standard wall-mounted unit with front air intake and outlet. The CDP70T is a “through-wall” model where air is drawn from one room (e.g., adjacent plant room) and exhausted to the pool hall through the wall. The T-model is 3dB quieter (47dB vs. 50dB) because the noisy components sit outside the pool space. Both have identical dehumidification capacity.

Q: How much does the CDP70 weigh and can my wall support it?
A: The unit weighs 75.5-77.5kg including refrigerant. The wall bracket distributes this load across multiple fixing points. Most solid masonry, blockwork, and stud walls (properly reinforced) can support this weight. For lightweight partition walls, install a timber or steel spreader plate across multiple studs, or use the optional floor mounting kit. Consult a structural engineer if unsure.

Installation & Setup

Q: Can I install this myself or do I need a professional?
A: Electrical connection must be performed by a qualified electrician per IET Wiring Regulations. Mechanical installation (wall mounting, drainage) can be done by competent DIYers with good skills. However, professional installation is recommended to ensure correct refrigerant circuit integrity, optimal placement, and warranty compliance. Dantherm dealers offer installation services.

Q: What happens if I can’t provide gravity drainage?
A: Install a condensate pump at the unit’s 3/4″ drain outlet. The pump lifts water to an elevated drain point (loft drain, first-floor waste pipe, etc.). Choose a pump rated for at least 3 litres/hour continuous flow. Many HVAC condensate pumps work perfectly. Ensure the pump has a reservoir to handle intermittent high-flow periods.

Q: Do I need to buy the through-wall duct kit?
A: For CDP70T through-wall models, the duct kit is highly recommended but not mandatory. It provides neat inlet/outlet grilles, sealing sleeves, and filters for a professional appearance. Without it, you’ll need to fabricate your own wall penetration solution and source grilles separately. The duct kit saves time and ensures proper fit.

Q: Can I connect this to a Building Management System (BMS)?
A: Yes! The CDP70 features a Modbus RS485 interface for integration with commercial BMS systems. This allows remote monitoring of humidity levels, operating status, fault conditions, and control of setpoints. A full Modbus register map is available from Dantherm support for system integrators.

Q: How do I connect an external humidity sensor?
A: The CDP70 has dedicated terminals for an external RH/T (relative humidity & temperature) sensor. Simply connect the sensor to the appropriate terminals (refer to wiring diagram in manual), then use the DIP switch on the control board to select “external sensor mode.” This allows placement of the sensor in a more representative location away from the unit’s immediate vicinity.

Operation & Maintenance

Q: How often do I need to clean the filter?
A: The foam pre-filter should be cleaned monthly in most pool environments. In heavy-use facilities or where airborne debris is significant (outdoor dirt, leaves tracked in), inspect every 2 weeks. To clean: remove front cover, pull out filter, wash in warm soapy water, rinse thoroughly, allow to dry completely, then reinstall. Replace filter annually or when damaged (Order Code: 094686).

Q: How much noise does it make in operation?
A: The CDP70 operates at 50 dB(A) at 1 meter (wall-mounted) or 47 dB(A) (through-wall). For reference, 50dB is similar to:

• Normal conversation at 1 meter distance
• Quiet office environment
• Rainfall or rustling leaves

It’s quiet enough that conversations near the unit are not disrupted. Through-wall models are 3dB quieter (perceived as 20-25% quieter) because mechanical components are in an adjacent space.

Q: What maintenance does the unit require?
A: Monthly: Clean air filter
Annually: Vacuum evaporator and condenser coils, inspect condensate drain, check electrical connections, verify refrigerant charge (qualified technician), test all safety cutouts

The compressor and fan motors are permanently lubricated and require no servicing. The CDP70 has a service interval reminder function that displays “SEr” when annual maintenance is due. Set the interval (1-99 weeks) in the menu.

Q: Can I run it 24/7 continuously?
A: Yes, the CDP70 is designed for continuous duty operation common in commercial pools. The unit will cycle on/off automatically based on humidity levels. When humidity is below setpoint (typically 50-60% RH), the compressor and fans stop, saving energy. It automatically restarts when humidity rises. There’s a 6-minute minimum delay between compressor starts to protect the compressor from short-cycling damage.

Q: What happens during a power cut?
A: The CDP70 will shut down during power loss. When power is restored, it automatically resumes normal operation according to the last programmed settings. All settings are stored in non-volatile memory (backed by battery). If humidity has risen significantly during the outage, the unit will immediately start dehumidifying to restore setpoint.

Performance & Efficiency

Q: How much will it cost to run per year?
A: Based on 1.8kW power consumption, annual costs range from:

• Light use (4 hrs/day × 200 days): £360-£504/year
• Moderate use (8 hrs/day × 300 days): £1,080-£1,512/year
• Heavy use (12 hrs/day × 350 days): £1,890-£2,646/year

(Calculated at £0.25-£0.35/kWh electricity rates)

However, the unit returns 3.24kW of heat to the room, which significantly reduces supplementary heating costs. Net operating cost is typically 30-50% lower when heat recovery is accounted for.

Q: Will it heat my pool room sufficiently?
A: The CDP70 alone provides 3.24kW of space heating through recovered heat. This is sufficient to:

• Offset heat losses in moderately insulated rooms (U-value 0.30 W/m²K or better)
• Maintain room temperature 2-4°C above outdoor temperature
• Replace heat lost through evaporation

For poorly insulated buildings or very cold climates, add supplementary heating using optional LPHW coil (+7.56kW, total 9.3kW) or electric heating coil (+5kW, total 6.27kW). The CDP70 controller can manage these heating systems automatically.

Q: What’s the most energy-efficient way to run it?
A: Follow these best practices:

1. Use a pool cover when pool not in use (reduces evaporation 60-90%)
2. Set humidity to 55-60% RH (not lower—over-drying wastes energy)
3. Set temperature to 28-30°C (higher temps increase evaporation)
4. Keep doors and windows closed (infiltration ruins efficiency)
5. Clean filter monthly (dirty filter reduces airflow, increases energy)
6. Annual professional service (optimizes refrigerant charge and components)
7. Run on off-peak electricity if possible (lower tariff rates)

Q: How long does it take to dry out a damp pool room?
A: This depends heavily on initial moisture load. For example:

• Newly plastered pool room: 4-8 weeks to dry out structural moisture
• After flooding/leak: 3-7 days to reach normal humidity levels
• Daily operation: Maintains 50-60% RH continuously

The unit can remove 69 litres per day, but building materials (concrete, plaster, grout) can hold 1000+ litres of moisture. Be patient during initial dry-out—this is normal. Once at equilibrium, the unit only removes water from pool evaporation (~10-30 litres/day for typical 50m² pools).

Troubleshooting & Support

Q: The LED is flashing red—what’s wrong?
A: Red LED indicates an alarm condition:

• Constant red + 3-second beep: High-pressure alarm (HP) – airflow restricted or condenser dirty
• Flashing red + double beep every minute: Low-pressure alarm (LP) – possible refrigerant leak
• Flashing red + single beep every 5 min: Sensor failure (SENS) – check sensor connections

Refer to the service manual troubleshooting section (pages 27-31) for detailed fault-finding procedures. If fault persists, contact Dantherm support or a qualified refrigeration engineer.

Q: Display shows “SEr”—what do I do?
A: This is the service interval reminder, not a fault. It indicates annual maintenance is due. Perform the maintenance tasks (clean coils, check drainage, inspect electrical, etc.), then reset the service interval in the menu:

1. Press OK to enter menu
2. Navigate to “SI” (Service Interval)
3. Set to desired interval (1-99 weeks)
4. Press OK to confirm

The “SEr” message will clear and the timer restarts.

Q: Condensate water isn’t draining—what should I check?
A: Common causes of drainage problems:

1. Blocked drain pipe: Flush with water to clear debris
2. Insufficient fall: Drain must have minimum 2% gradient (20mm/meter)
3. Kinked flexible hose: Straighten or replace hose
4. Frozen trap: In unheated spaces, insulate drain pipe
5. Drip tray overflow: Clean drip tray and outlet spigot monthly

If water backs up into unit, shut down immediately to prevent electrical damage. Resolve drainage issue before restarting.

Q: The unit runs but humidity stays high—why?
A: Several possibilities:

1. Doors/windows open: Infiltration overwhelms dehumidification capacity
2. Undersized for application: Room/pool larger than 70m² requires more capacity
3. High bather load: Many users add moisture faster than removal
4. Dirty filter/coils: Restricts airflow, reduces performance by 30-50%
5. Refrigerant leak: Requires professional service (check for LP/HP alarms)
6. Setpoint too high: Lower humidity setpoint to 50% RH (not below 45%)

Check obvious issues first (doors, filter), then contact support if problem persists.

Q: Where can I get spare parts?
A: Spare parts are available through:

• Dantherm authorized dealers (UK-wide network)
• Certikin distributors (listed on their website)
• Direct from Dantherm support: support.dantherm.com or shop.dantherm.com

Common spare parts:

• Replacement filter (Code 094686)
