Repair
General advice
Repairs should only be undertaken by an authorised specialist company. The following
advice is designed to ensure trouble-free operation and a long service life for your heat
pump.
Repair and maintenance of a SET heat pump should only be carried out by qualified or
trained personnel who have been instructed about the tasks entrusted to them and about the
potential dangers of improper conduct.
In the connection diagrams, no protective measures are specified. These must be provided
in addition for the assembly of the plant, or when connecting the devices according to VDE
0100 and the provisions of the relevant energy supply companies.
35mA type B residual current circuit breakers and type C back-up fuses should be used.
Please note that the operating voltage is 230V or 400V at 50Hz. The control voltage
is max. 24V.
Before starting any maintenance or repair work on the heat pump, the power supply
must be switched off. Danger of death from electric shock!
Before opening the control cabinet and/or the device, the power supply must be
switched off! Danger of death from electric shock!
The fans must not be opened or operated during operation.
Within the warranty period, repairs to the heat pump must only be undertaken by
SET Energietechnik Ltd. or their representatives.
Unauthorised conversions and modifications to the device must not be undertaken
for safety reasons. This would lead to the warranty becoming void and to the
termination of conformity.
No foreign parts may be used on the device, as compliance with the required safety
and operability may not be guaranteed. The user/operator, and not the
manufacturer, shall be liable for any resulting damage or injuries.
