Water Connection and Bypass Kit Installation
The following retail components (not included) are recommended for the hydraulic connections:
• Cut-off valves upstream and downstream from the heat pump to facilitate maintenance and/or
heat pump bypass from the pool water circulation system.
• A non-return or check valve, installed between the pool and the heat pump outlet fi tting, to
prevent water refl ux.
All chemical feeder or water treatment devices must be installed downstream from the heat pump
and non-return (check) valve. It is important to install a check valve to prevent chemical saturated
water refl ux which could damage the heat pump and void the warranty.
The water circulation system must be arranged observing the following general layout:

Condensation Draining Hose Installation
NOTE:
The air drawn into the heat pump is strongly cooled by the operation of the heat pump for
heating the pool water, which may cause condensation on the evaporator fi ns. The amount of
condensation may be as much as several liters per hour at high relative humidity. This is
sometimes mistakenly regarded as a water leak.
