Waterco Hydrochlor MK3 Mineral Chlorinator – Power Pack for Mineral and Saltwater Pools
Overview
The Hydrochlor MK3 Power Pack serves as the advanced control unit for Waterco’s MK3 Mineral/Salt Chlorinator systems. Featuring energy-efficient switch‑mode technology, intuitive controls, and essential safety protections, it delivers reliable, automatic chlorination for swimming pools up to 100 m³ when paired with the appropriate cell.
Key Features
- 
50%+ Energy Savings 
 Switch‑mode power design greatly reduces electricity usage while maintaining chlorine production.
- 
Auto-Cell Recognition 
 Adjusts output based on the connected 20A or 30A cell for optimal performance.
- 
Salt-Level Protection 
 Audible and visual alarms detect low/high salt (< 4,000 ppm or > 6,000 ppm); output is automatically limited if outside optimal range.
- 
Built-In Timer with Backup 
 Easily set daily or weekly chlorination schedules. Supercapacitor backup holds the schedule for at least 150 hours during power outages.
- 
Self-Cleaning Chlorinator Support 
 Enables polarity-reversal to reduce calcium build-up on cell electrodes—automatic operation.
- 
No-Flow Detection 
 Automatically shuts off chlorine production and triggers an LED alert if water flow stops.
- 
Weather-Proof and Durable 
 IP23-rated housing with UV-stable connectors and easy-to-use brass-pin cell plugs ensures outdoor reliability.
- 
Winter & Shock Modes 
 Easy switch to reduce output in cooler months or boost output for pool shock/super chlorination.

Benefits
- 
Consistent Sanitization 
 Automatically maintains ideal chlorine levels—reducing bacterial and algal risks.
- 
Comfort-Focused Water 
 Mineral-enriched or salt-treated water is gentler on skin and eyes compared to traditional chlorine.
- 
Minimal Maintenance 
 Self-cleaning cell reduces scaling, while LED alerts and timer simplify upkeep.
- 
Safe and Intelligent Design 
 Integrated safeguards (no-flow detection, salt-level control, pump protection) ensure reliable operation.
- 
Eco-conscious Operation 
 Energy-efficient design and optimized chlorination reduce electricity and chemical consumption.
Installation & Use
- 
Mounting: Install control unit near filter and cell, away from chemical storage. Pump outlet drives filtration pump only. 
- 
Cell Placement: Position cell at end of filtration line, with proper gas trap and flow direction. 
- 
Startup Sequence: Power the unit for ≥150 hours initially to charge backup capacitor. 
- 
Water Requirements: Maintain pool salt/mineral level between 4,000–6,000 ppm. 
Summary
The Waterco Hydrochlor MK3 Power Pack is a smart, energy-efficient, and versatile chlorination controller, designed to deliver precise, low-maintenance sanitization for pools up to 100 m³. With intelligent controls, long-term reliability, and compatibility with mineral and salt systems, it’s a superior upgrade for those seeking comfort, efficiency, and safety.
