MAINTENANCE

Cleaning

To ensure optimum performance of the heat pump, follow these recommendations:

• Backwash the filter of the pool on a regular basis in order to ensure proper flow rate through the pool heater.

• Keep the surfaces of the coil clean and free of any obstruction such as papers, leaves or other debris.

• Carefully clean the unit using a soft, non abrasive and bleach free cleaner, and rinse using a garden hose without the

nozzle.

• Check the drainage holes of the base of the unit to make sure that they are clean and unobstructed. (This prevents

water from accumulating in the heat pump.)

Winterizing (Titanium Heat Exchanger)

If you close the swimming pool during the winter season, it is essential to drain the unit in order to prevent the

formation of ice in the condenser (water section). To winterize the heat pump, you must :

1. Turn off the unit.

2. Shut off the breaker of the heat pump electrical supply line.

3. Disconnect the water inlet and outlet connections (Figure A).

4. Freely flush the condenser.

5. If the heat pump is left outside during winter, protect it with a waterproof cover.

Seasonal Start-up

Before starting the pool heat pump for the first time of the season, you must:

1. Make sure that the electrical breaker of the pool heat pump is in the off position.

2. Flush with tap water until clean.

3. Replumb the heat pump and close by-pass valve (to avoid high concentration of water from entering the heat pump).

4. Clean the pool filter and make sure the water is flowing adequately through to pool return line.

5. Chemically balance and clean pool water.

6. Switch on the breaker of the heat pump electrical supply line.

7. Open bypass valve.

WARNING

Before performing any maintenance on the heat pump you must turn off the electricity at the breaker of the

electrical supply line.

Loosen

bypass valves
