Electrical Connection - LAMINOX KING HEAT 6 User Manual

Air vent valves and suitable devices should be fitted for the correct removal of air from the
circuit during the filling stage.
All water circuit piping MUST be insulated to prevent condensation during
operation in cooling mode and reduction of the cooling and heating capacity, as well as to
prevent freezing of outside pipes during winter. The minimum insulation thickness of the
pipes should be 19mm(0.039W/mK), preferably comprising a closed cell insulation or a
vapour barrier. In outdoor areas exposed to the sun, the insulation must be protected from
the effects of degradation.
The water circulation pump must at all times be operational (even if unit is not
running) to prevent any possible damage due to freezing. Even when in standby
mode, the circulation pump is controlled directly from the unit, which takes the
outdoor temperature and temperature in pipe into consideration to decide whether to
circulate water within the system.
Important: Even though the unit has anti-freeze protection, if the circulation pump
fails or there is a problem with the power supply, there is still a risk of damage due to
freezing. During the installation Anti-freeze (Ethylene Glycol) is strongly
recommended. If the air temp is ever lower than 0°C, it must use enough glycol.

4.4 Electrical Connection

The electrical installation of the heat pump and its electrical accessories should be carried
out by qualified personnel, subject to the current installation regulations on the matter. The
electrical installation must be connected so that the heat pump can be fully isolated and
disconnected for the safe execution of any maintenance operations.
Th machine has 2 holes with cable grommets in its back side to introduce all connection
cables inside the machine. The cables exposed to the weather conditions of the exterior
should be protected by means of protective raceways or pipes. Alternatively, they should be
of a suitable category for use outdoors (H07RN-F type or higher). It is also advisable to
keep the high -voltage cables (general supply, diverted valves, electrical heaters, circulation
pumps, etc.) at a minimum distance of 25 mm low-voltage cables (controller board cable,
temperature sensors, room sensor, etc.) and drive them through independent pipes.
IMPOTTANT: Before carrying out any work on the electrical installation
of the heat pump, always ensure it is disconnected from
the mains.
