Heat Pump Location - GRE HPG25 Manual De Instrucciones

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. Install a bypass if the water flow from the swimming pool pump is more than 20% greater than the
allowable flow through the heat exchanger of the heat pump.
3. Install the heat pump above the water level of the swimming pool.
4. Always place the heat pump on a solid foundation and use the included rubber mounts to avoid
vibration and noise.
5. Always hold the heat pump upright. If the unit has been held at an angle, wait at least 24 hours
before starting the heat pump.

3.2 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, unlike the situation with a gas
heater (including pilot flame problems).
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.
See the drawing below for minimum dimensions.
3.3 Distance from your swimming pool
The heat pump is normally installed within a perimeter area extending 7.5 m from the swimming pool. The
greater the distance from the pool, the greater the heat loss in the pipes. As the pipes are mostly
underground, the heat loss is low for distances up to 30 m (15 m from and to the pump; 30 m in total) unless
the ground is wet or the groundwater level is high. A rough estimate of the heat loss per 30 m is 0.6 kWh
(2,000 BTU) for every 5 ºC difference between the water temperature in the pool and the temperature of the
soil surrounding the pipe. This increases the operating time by 3% to 5%.
