1. Safety instructions
If the heat pump is tipped to one side, it must re-
main in an upright position for at least seven hours
before being operated again.
• Always keep the heat pump in an upright posi-
tion during storage, transport and operation.
• Carry the heat pump only at the carrying handles.
• Do not lift the heat pump by its copper pipes or
they may get bent.
Caution: the voltage in the compressor circuit is
dangerous to touch!
• Do not thermally insulate the compressor or it
may overheat.
• After shut-down by the overpressure cut-out
switch wait for 10 minutes to press the green re-
set button.
2. Description
Demonstration model of an electrically powered
compressor heat pump for demonstrating how a
heat pump or a refrigerator operates. Can be oper-
ated as a water-air or water-water heat pump.
The demonstration model of an electrically powered
compressor heat pump consists of a compressor with
a drive motor, an evaporator, a condenser and an
expansion valve. These components are connected in
a closed system by means of pipes and built onto a
base.
The energy monitor allows to record and display the
electrical performance data of the compressor.
