WATER SUPPLY AND BACKFLOW
All ECOLO 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 liters per minute (15 U.S. gallons
per minute) and 170 liters 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.

If the above-prescribed water flows are not respected,
