If the temperature is higher than 30°C and the humidity is higher than RH 80%, the
thickness of the insulation materials should be at least 20 mm to prevent
condensation on the surface of the insulation.
Use separate thermal insulation pipes for the gas and liquid refrigerant piping.
INFORMATION
Also read the precautions and requirements in the "General safety precautions"
chapter.
WARNING
▪
If the power supply has a missing or wrong N-phase, equipment might break
down.
▪
Establish proper earthing. Do NOT earth the unit to a utility pipe, surge absorber,
or telephone earth. Incomplete earthing may cause electrical shock.
▪
Install the required fuses or circuit breakers.
▪
Secure the electrical wiring with cable ties so that the cables do NOT come in
contact with sharp edges or piping, particularly on the high-pressure side.
▪
Do NOT use taped wires, stranded conductor wires, extension cords, or
connections from a star system. They can cause overheating, electrical shock or
fire.
▪
Do NOT install a phase advancing capacitor, because this unit is equipped with an
inverter. A phase advancing capacitor will reduce performance and may cause
accidents.
WARNING
▪
All wiring MUST be performed by an authorised electrician and MUST comply
with the applicable legislation.
▪
Make electrical connections to the fixed wiring.
▪
All components procured on-site and all electrical construction MUST comply
with the applicable legislation.
WARNING
The backup heater MUST have a dedicated power supply and MUST be protected by
the safety devices required by the applicable legislation.
WARNING
ALWAYS use multicore cable for power supply cables.
