Installation

Water connections

The heat pump must be installed between the filter discharge and the pool return line, and as closely as possible to the pump and the electrical circuit in order to minimize the connections costs. Moreover the use of 90° angles and small radius angles should be kept to a minimum. The unit must be connected to a dedicated circuit.

Although not essential for the functioning of the unit, the installation of a system of service and derivation valves is highly recommended (see above). This installation will allow for more flexibility during maintenance and during winterizing, and will also protect the heat exchanger from erosion and corrosion.

If an automatic sanitizer system (chlorine, bromine) is integrated to the filtration system, an insulated check valve must be installed, on the intake, on the circuit. The check valve in the automatic sanitizing unit is notacceptable. The use of check valves will prevent the premature corrosion of the pool heater's internal elements.

Note: In areas where the temperature can drop to below 12°C (50°F) during the swimming season the use of a three-way valve or a system of by-pass is required.

WARNING: It is extremely important that the automatic sanitizer system is installed downstream from all the heating and water purification accessories. Any noncompliant installation of any such equipment will void the manufacturer's warranty.

The heat pump unit features an easy installation method for the water connections to the pool plumbing system, this can be done by the skilled user or a skilled handyman.

Note: the use of 1 ½" inside diameter flexible hoses or pipes, tightened by stainless steel pipes are recommended.

1. Connect the water line from the filter to connector "water in" on the base of the heat pump.
2. Connect the pool water return line to connector "water out" on the base of the heat pump.
3. Once the connections have all been made turn on the filter pump to verify the water circulation and that the connections are watertight. The flow rate should be at least 95 litres/minute (25 U.S. GPM).
4. For a higher capacity heat pump the maximum number of litres flowing through the exchanger must be less than 227 litres/minute (60 U.S. GPM). Optimum water flow is 200 litres/minute, if the flow rate is higher install a bypass valve to adjust the flow.
