Installation Instructions
•
The device must only be installed by authorised personnel.
•
The unit is designed for a power supply of 400 or 230V/50Hz.
•
Recommended protection for use with the electric boiler is 3F-16A/D, and
without the electric boiler 1F-16A/D.
The device should be installed externally, preferably vertically to the wall of the
building, in a position that ensures smooth air circulation. It is suitable to install the
device close to a drainage canal, 20 cm above the terrain. The unit should be mounted
to the bearing construction using screws and anti-vibration rubber mounts. Select the
area of its placement in such a manner that neither airborne nor construction noise can
travel into premises designated for resting in the owned or the neighbouring property.
Commissioning of the Heat Pump
•
Check that the HP is properly shielded and no foreign objects are present on its
surface.
•
Check that the unit is properly filled and is deaerated.
•
Check that the water flow through the HP is supplied.
•
Check the system's connection to the electricity supply and its grounding.
•
Turn on the heating pump. After several minutes the system should automatically
start operating.
•
Check that the pump is rotating smoothly without making any unusual noises and
that the unit does not shut down at short intervals (in less than 15 minutes).
•
Check that the HP is supplying thermal energy and notice whether there is any
increase in the temperature of the input or the output water.
•
During periods of low outdoor temperatures undertake periodical check-ups of the
unit and in case of freezing, reset the time parameters for defrosting (this also
depends on the presence of any water surface in the area surrounding the system).
Maintenance
The LWRc-8kW heat pump is fully automatic.
•
The input water filter must be cleaned periodically.
•
Periodically clean any solid impurities and dust from the air section of the heating
pump.
•
If there is anything amiss with the unit and if the customer is unable to solve the
problem, contact the supplier or our company for the remedying of the problem.
•
The system must be operated with water that meets the requirements for heating
water (max. 7 degrees of hardness and a pH ranging between 7.8-8.5).
