CAUTION
▪
Incomplete flaring may cause refrigerant gas leakage.
▪
Do NOT re-use flares. Use new flares to prevent refrigerant gas leakage.
▪
Use flare nuts that are included with the unit. Using different flare nuts may
cause refrigerant gas leakage.
CAUTION
Install the refrigerant piping or components in a position where they are unlikely to
be exposed to any substance which may corrode components containing refrigerant,
unless the components are constructed of materials that are inherently resistant to
corrosion or are suitably protected against corrosion.
Electrical installation (see
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
▪
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
ALWAYS use multicore cable for power supply cables.
WARNING
Use an all-pole disconnection type breaker with at least 3 mm between the contact
point gaps that provide full disconnection under overvoltage category III.
WARNING
If the supply cord is damaged, it MUST be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid a hazard.
