SELECTION OF THE INSTALLATION PLACE
When choosing the installation place of the heat pump, keep in mind that the heat pump
produces a certain level of noise (see table “Heat pump technical data”).
The device must be mounted on a flat and stationary surface with a permissible load of at least
500 kstr. Minor surface irregularities can be compensated by adjusting the feet of the device.
The ambient temperature near the heat pump must be between 10°C and 35°C, and the relative
humidity must not exceed 80%.
There must be no aggressive chemicals in the environment.
The heat pump should not be installed close to walls; the front of the unit should always be
accessible (see, Annex No 6).
A drainage system must be provided in the room where the unit is installed. In this case, leaking
water can be drained.
Do not use extra platforms.
PRELIMINARY PREPARATION OF THE PIPELINES
The connecting pipes for the outdoor circuit, the heating circuit and, if provided, the hot water
circuit must be laid up to the intended location of the heat pump. Install an expansion vessel, safety
valves, coarse suction filters and pressure gauges for the outdoor, heating circuit and boiler. The
circuits must have a provided filling point.
OUTDOOR CIRCUIT
Installation and filling
The outdoor circuit can be vertical (boreholes) or horizontal. The horizontal circuit must be
installed below the freezing zone, depending on the ground of the installation site. Fill the outdoor
circuit with glycol, which ensures that it does not freeze in temperatures up to -15
o
C.
Do not use the
salt-based solution.
The following fluids are approved for the outdoor circuit:
• monoethylene glycol;
• propylene glycol.
It is recommended to use a mixture of water and monoethylene glycol concentrate in a ratio of
3:1.
The applicable rules and regulations must be observed when installing and filling the outdoor
circuit. There must be no stones or sharp objects in the ground where the outdoor circuit is installed
that could damage the pipes. Prior to filling the system, make sure that the system is tightly sealed.
When installing the outdoor circuit, it is necessary to protect the pipes from penetration of dirt
or gravel. If the system is dirty, the heat pump may become clogged and individual components of
the device may be damaged or corrupted.
Filling and circulating unit
The outdoor system refiller must be installed next to the circuit inlet so that the system can be
replenished when the system pressure drops and the external and glycol mixing procedure can be
performed when filling the outdoor circuit.
The filling unit is not included in the heat pump
package.
