Indoor unit
• Do not splash water directly.
Wipe the unit gently with a soft dry cloth.
Anode Bar
Sanitary Water Tank
Water Filter Set
Water pressure gauge
• Do not press or hit the glass cover
using hard and sharp objects.
Failure to do so may cause
damage to the unit.
• Ensure that the water pressure
is between 0.05 and 0.3 MPa
(0.1 MPa = 1 bar).
• In case the water pressure is out
of the above range, consult an
authorised dealer.
Outdoor unit
• Do not obstruct the air inlet and outlet vents. Failure
to do so may result in low performance or system
breakdown. Remove any obstruction to assure the
ventilation.
• When it snows, clean and remove snow around the
outdoor unit to prevent the air inlet and outlet vents from
being covered with snow.
Non serviceable criteria
Disconnect the power supply
then please consult an authorised dealer under the
following conditions:
• Abnormal noise during operation.
• Water/foreign particles have entered the control panel.
• Water leaks from the indoor unit.
• Circuit breaker switches off frequently.
• Power cord becomes unnaturally warm.
For extended non-use
• The water inside the Sanitary Water Tank should be
drained.
• Disconnect the power supply.
MAINTENANCE
User
• In order to ensure optimal performance of the units, user may inspect and clear any obstruction on the air inlet and outlet
vents of the outdoor unit.
Dealer
• In order to ensure safety and optimal performance of the units, seasonal inspections on the units, functional check of
RCCB/ELCB, field wiring and piping have to be carried out at regular intervals by authorised dealer.
• Specific to the Sanitary Water Tank, it is important to service the Water Filter Set periodically and inspect the Anode
Bar annually. The Anode Bar which protects the tank body will corrode, depending on water quality. When diameter is
approximate 8mm, the Anode must be replaced.
• Users should not try to service or replace parts of the unit.
• Contact authorised dealer for scheduled inspection.
