Swimming pool Heat Pump

4. Guidelines

4.1 Water chemistry

Special attention should be paid to the chemical balance of the pool water. The pool water values should
always stay within the following limits:
pH
Free chlorine(mg/1)
TAC(mg/1)
Salt(g/1)
Important: failure to comply with these limits will invalidate the warranty.
Note: exceeding one or several limits can damage the heat pump beyond repair. Always install water
treatment equipment past the heat pump's water outlet, especially if the chemicals are automatically
added to the water.
A check- valve should also be installed between the outlet of the heat pump and this equipment in
order to prevent products from flowing back into the heat pump if the filter pump stops.

4.2 Winterizing

Important: failure to winterizing could damage the heat pump and will void warranty
The heat pump, filter pump, filter and conduits must be protected in areas where the temperature can drop
below the freezing point, Evacuate all water from the heat pump as follows:
1. Turn off the electrical power supply to the heat pump
2. Close the water supply to the heat pump: completely close valves 2 and 3 of the by-pass
3. Disconnect the water inlet and outlet coupler fittings of the heat pump and let the water drain out of the
unit

4.3 Spring startup

If your heat pump has been winterized, perform the following steps when starting the system in the spring:
1. Inspect the system for any debris or structural poroblems.
2. Connect the water inlet and outlet unions firmly.
3. Turn on the filter pump to supply water to the heat pump. Adjust the by-pass to allow water flow through
the heat pump.
4. Turn on the electrical power to the heat pump at the main breaker panel.
