ting feet down). In case of doubts, wait for the heat pump to start for min. 24 hours
after installation to prevent damage to the compressor. If the heat pump is handled
correctly (with the feet down), it can be started immediately.
3.4 Pool site selection
The heat pump is designed for outdoor installation and will work well in virtually
any outdoor environment if the following three conditions are met:
1. Fresh air – 2. Electric power - 3. Piping with pool filtration
(a) Do not install the pump in an enclosed space with
limited air access and thus without sufficient air
circulation. The air supply and vent from the heat
pump must be completely free of any obstacles.
No objects have to be found in the working spa-
ce around the heat pump defined in the figure
next to it. Do not place it even between bushes
and grates, which can also restrict air access. Any
obstacles to the free flow of air reduce the effici-
ency of the heat exchange and can even cause the
pump to stop completely. Make also sure that the air coming out of the heat pump
cannot fly back and be sucked in again (it is important to have at least min. 2 meters
of free space in the direction of the air outlet from the heat pump).
(b) The device must be installed in a place protected from direct sunlight and other
heat sources, and preferably so that it can suck in air from a sunny area. It is
recommended to build a loose roof above the heat pump to protect the device
from direct rain and sunlight.
(c) Do not place the device near car traffic. Increased dust formation causes a gra-
dual deterioration in the efficiency of heat exchange.
(d) The air outlet should not be directed to places where the flow of cold air could
be annoying (windows, terrace, ...). Do not orientate the air outlet against the
direction of the prevailing winds.
(e) The distance between the device and the edge of the pool must not be less than
3.5 m. It is recommended to install the heat pump at a distance of max. 7.5 m
from the pool. The greater the distance from the pool, the greater the heat loss
in the piping. The total length of the connecting pipe should not exceed 30 m. It
must be taken into account that the longer the length of the connecting pipe, the
greater the heat loss in the distribution line. When embedding most of the pipes
underground, the heat losses are smaller, but to give you an idea of 30 meters of
distribution line (if the ground is not wet) it has about 0.6 kW / hour (2000 BTU) of
heat for every 5°C difference between the water temperature in the pool and the
temperature of the ground surrounding the pipes, which can be converted into
about 3 - 5% extension of the operating time of the heat pump.
(f) The device must be installed on a flat and solid surface, such as a concrete plinth
or a steel base. The heat pump housing must be anchored to the surface (plinth
or base) with screws or bolts via rubber anti-vibration inserts. Rubber anti-vibra-
tion inserts (silent blocks) not only reduce the noise of the heat pump, but also
extend its life service.
