Avoid excessive heating orcooling.• Prevent direct sunlight from entering a room dur-ing cooling operation by using curtains or blinds.• Ventilate often.Extended use requires special attention to venti-lation.• Do not keep doors and windows opened. If thedoors and windows remain open, air will flow outof your room causing a decrease in the cooling orheating effect.• Never place objects near the air inlet or the airoutlet of the unit. It may cause deterioration in theeffect or stop the operation.• Turn off the main power supply switch to the unitwhen the unit is not used for longer periods oftime. If the switch is on, it uses electricity. Beforerestarting the unit, turn on the main power supplyswitch 6 hours before operation to protect the unit.(Refer to the chapter “Maintenance” in the indoorunit manual.)• When the display shows “ ” (time to clean theair filter), ask a qualified service person to cleanthe filters.

Do not let the air blow directly to aperson.• Make sure that the inlet and outlet of the indoorunit are not clogged.8. MAINTENANCE8-1 HANDLING OF HEAT SOURCE WATERRequests from manufacturer;• Do not fail to mount a strainer (sold separately asan accessory) in the inlet pipe for heat sourcewater intake.• Do not use any water contaminated by relativelyhigh level of foreign materials for heat source.• Carry out the control of water quality without fail.Otherwise, corrosion of condenser or pipingoccurs or germs may be generated.• For the timing of cleaning and its method, consultwith the dealer you purchased the unit.Cleaning of the heat-exchanger on the water side• Water scales, mosses, etc will accumulate on theheat-exchanger on the water side within an air-conditioner during use for a long period. Carry outcleaning at a regular interval. If water scales,mosses, etc. have accumulated, the cooling andheating capacity may decline. The safety devicewill be repeatedly actuated causing normal oper-ation to become impossible.• For use in an area where the water quality is poor,increase the frequency of cleaning.Cleaning of strainer• Clean the strainer in the inlet pipe of heat sourcewater intake.8-2 AT THE BEGINNING OF THE SEASONCheck• Are the inlet and outlet of the indoor unit blocked?Remove anything blocking them.• Run the pump and make sure that the water is cir-culating.If you operate without water circulating, the unitmay be damaged.Clean the air filter and exterior.• After cleaning the air filter, be sure to put it back inthe same position.See the operation manual included with theindoor unit for details on how to clean it.Turn the power on.• When the power comes on, the characters in theremote controller display appear.(To protect the unit, turn the power on at least6 hours before operating.
