3. Installation and connection
3.1 Notes
The factory supplies only the heat pump. All other components, including a bypass if necessary, must be
provided by the user or the installer.
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 – 2. Electricity – 3. Swimming pool filters
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.
