When the cover panels are disassembled, the energised parts can be easily accessed. Never leave
the unit unattended during installation or during maintenance work when the cover panel is
removed.
Do not touch the coolant pipes, water piping, or internal parts during and immediately after
operation. Pipes and internal parts may be excessively hot or cold, depending on the use of the
unit.
The hands may be burned by cold or heat in case of improperly touching pipes or internal parts. To
avoid injury, wait until the pipes and internal parts return to their normal temperature.
Alternatively, if access is required, be sure to wear appropriate safety gloves.
1.3 Transport, storage and handling warnings
DUAL CLIMA heat pump must be transported, handled and stored vertically. Tipping the machine
may cause the oil to be emptied inside the compressor, causing premature rupture of the machine
when the machine is started.
OK NO OK
The heat pump packaging has a "tilt indicator" label to ensure that the machine has not been
overturned during transport and storage. Before receiving the machine from your supplier
(distributor), check the status of this indicator and refuse the device without unpacking it if
the warning switch of the label indicates that it has been overturned.
Do not twist, loosen or pull the external electric cables of the heat pump. Do not insert any sharp
objects through the fan grille or into the fan itself.
Do not wash the interior of the heat pump with water as this may result in electric shock or fire. For
any cleaning and/or maintenance operations, disconnect the main power supply.
1.4 Freeze protection warnings
DUAL CLIMA heat pump is a machine that is installed in the exterior of the house, so that it will be
exposed to the extreme climatic conditions of cold in the periods of frost. Due to this, it is of
paramount importance that this type of machine is protected against such frost. The freezing of the
water inside the heat pump causes the heat pump to breakdown, with the subsequent interruption
of its operation and major economic expenses involving its repair.
It is mandatory to use a safety system in the installation to prevent the freezing of water in the
machine. DOMUSA TEKNIK proposes the use of glycol in the water circuit of the pump, or some
antifreeze valve system to empty the installation in conditions of low temperatures. Carefully read
the
"Freeze Protection" section in this manual for more detailed information on these systems.
DOMUSA TEKNIK will not cover damages caused by the lack of any of these antifreeze safety
systems.
