MAINTENANCE
Fan-coil units must be disconnected from mains power and
secured against unintentional re-connection before any
maintenance work. All work must be in accordance with all
applicable safety and health rules and regulations.
Filter Maintenance The filter pad may be cleaned or
replaced.
For cleaning, a vacuum-cleaner operating at medium or low
suction should be used.
For replacement, the fasteners of the intake grille must be
opened and the grille must be removed. The filter pad must
then be taken out and replaced. Finally, the intake grille
must again be locked in place.
CLEANING, MAINTENANCE AND SPARE PARTS
Maintenance of the unit must be carried out by trained
maintenance personnel only.
FAN:
No maintenance required.

OPERATING GUIDE

• The temperature should not be set lower than what you
need. This would result to increase energy cost.
• Clean the air filter every week for higher efficiency.
• Draw close curtains or close glass windows when cooling
to prevent heat load from sun light which may cause more
electricity cost.
• To distribute cool air through out the room, adjust air flow
direction as shown by the arrows (see picture) to diffuse
cool air.

PRECAUTIONS

• Check electrical system (voltage and frequency). Use the
proper power supply indicated on the unit to operate the
air conditioner and only fuses with specified capacity. Do
not use pieces of wire instead of fuse.
• Do not insert objects into the air inlet or outlet when the air
conditioner is running as it may case damage or personal
injury. Also pay special attention when children are
around.
• Do not channel the air flow directly at people, especially
infants, aged persons, or patients.

TROUBLESHOOTING

1 The motor does not rotate or rotates incorrectly.

PROBLEM
HEAT EXCHANGER COIL:
No ordinary maintenance required.
FILTER:
Using a suitable tool, unhook the filter holder strip and
extract the filter from the guides.
Clean regularly with a vacuum cleaner or shake lightly.
When it can no longer be cleaned, replace.
SPARE PARTS:
To order spare parts, always give the model of appliance
and a description of the component.
IMPORTANT!
BEFORE CARRYING OUT CLEANING OR MAINTE-
NANCE, MAKE SURE THE POWER TO THE UNIT IS
TURNED OFF
IMPORTANT!
ALWAYS REPLACE THE FILTER AFTER CLEANING.
• Close windows and doors while operating the unit to pre-
vent leakage of cooled air to save energy.
• In case of ineffective ventilation, open the window to venti-
late the room air once in a while but not too long since
cooled air will be uselessly drained out.
• Turn off the air conditioner if, while running, electricity
interference occurs. If the unit is not to be used for a long
time, cut off the power supply main switch.
• Do not locate any obstacles against the air flow direction
of indoor and outdoor units. Inefficient performance or
malfunction may result.
Do not locate a heater or any other heat sources close
to the unit . The heat may deform the plastic parts.
REMEDY
Make sure the power to the unit is on.
Make sure the wires are correctly connected, referring to the
wiring diagram.
Control if the main switch, the seasonal commutator and the
thermostat are in the right position.
Make sure the fi lter is clean.
Make sure the hydraulic circuit is free from air by venting the
heat exchanger.
Make sure it is sloping in the direction of the condensate
drain.
Make sure the condensate drain is not clogged.
