WATER SUPPLY AND BACKFLOW
PLUMBING CONNECTIONS
All Elite model connections have a 1 ½’ diameter.
MINIMUM AND MAXIMUM WATER FLOWS
For maximum efficiency, your heat pump must operate with water flows between 57 litres per minute (15
U.S. gallons per minute) and 170 litres per minute (45 U.S. gallons per minute). With a water flow of less
than 57 lpm (15 U.S. GPM) and greater than 170 lpm (45 U.S. GPM), the heat pump will not work
properly and will suffer damage. (See table below).
A set of valves (Fig. A) to insulate the heat pump and adjust the water flow must be installed.
We recommend installing this set of valves (Fig. A) in order to be able to adjust the optimal water flow
circulating in the heat exchanger (condenser). An adjustable automatic bypass valve must be installed
when a water pump of 2 HP or more is used to circulate the pool water.
Your water pump must be able to supply each heat pump with a water flow within the limits listed below.

WARNING
If the above-prescribed water flows are not respected,
damage will ensue and your warranty will be void.
WARNING
Elite pool heat pumps normally operate with a 1.4 bar (20 PSI) water
pressure. The maximum operating water pressure is 2.0 bars (30 PSI).
Failure to respect the prescribed water pressures will void the warranty of
your heat pump.
