Installation And Connection; Heat Pump Location; Initial Operation - GRE HPM20 Manuel D'instructions

4. Installation and connection

Attention:
Please observe the following rules when installing the heat pump:
1. Any addition of chemicals must take place in the piping located downstream from the heat pump.
2. Always hold the heat pump upright. If the unit has been held at an angle, wait at least 24 hours before
applying main power to the heat pump.

4.1 Heat pump location

The unit will work properly in any desired location as long as the following three items are present:
1. Fresh air
The unit may be installed in virtually any outdoor location as long as the specified minimum distances to other
objects are maintained (see drawing below). Please consult your installer for installation with an indoor pool.
Installation in a windy location does not present any problem at all.
ATTENTION: Never install the unit in a closed room with a limited air volume in which the air expelled from the
unit will be reused, or close to shrubbery that could block the air inlet. Such locations impair the continuous
supply of fresh air, resulting in reduced efficiency and possibly preventing sufficient heat output.

4.2 Initial operation

Note: In order to heat the water in the pool (or hot tub), the filter pump must be running so the water to is
circulating through the heat pump. The heat pump will not start up if the water is not circulating.
