CHARACTERISTICS AND REQUESTS
ABOUT YOUR GAS HEAT PUMP AIR CONDITIONER
The gas heat pump air conditioner (GHP) uses gas as the fuel to drive the compressor. As it uses gas engine, there are various characteristics.
Even on very cold days the unit doesn't almost frost up so it provides stable heating operation.
As the electric power consumption is about 3 kW, this leads to be less received power equipment.
However, as with a car engine, periodical inspections by a specialist are for efficient use needed for a comfortable operation. Please make sure you have these periodical inspections.
PLEASE ENSURE YOU SIGN UP FOR A REGULAR CHECK UP CONTRACT
In order to have a comfortable operation of GHP for a long period, periodical inspections are necessary. Please conduct yearly inspections supported by a specialist.
What will happen if you don't have periodical inspections.
1.The engine oil will deteriorate, causing a malfunction.
2.The air cleaner element will be clog up, causing carbon monoxide and occasional reduction of performance.
REQUESTS
Once signed up for a periodical inspection, a specialist will call on depending on the length of time the unit has been in use. After a fixed period of in use hours. the remote controller will display "Oil lnspection". At this time we would appreciate you contacting your dealer or service center for a check up.
For details please refer to page 3.
CHANGING ENGINE OIL
Periodically change engine oil and oil filter.
If you forget to change engine oil or use a non-specified oil, it may have a bad effect on the engine and be the cause of trouble.
* Engine Oil (Genuine Oil)
CAUTION
Filling in too much oil will have a bad effect on the engine.
PIease consult with your service center or dealer when changing the oil.

Please obey the following regarding the power source installed nearby the unit:
•Please do NOT operate the equipment with the at hand power source. Your air conditioner is a multi-type air conditioner.
If you turn off one of the power sources installed near by the unit, all the units with the same power source will become inoperable.
•Please turn on the power switch at least 5 hours before operating the air conditioner. In order to protect the compressor, the crank case heater is provided. Please be sure to carry out the following:

•During maintenance, turn the power switch OFF.
•During seasons of use please do NOT turn the power switch OFF.
•Be careful about cold water (hot water) freezing.
When operating heaters in cold districts (regions where outdoor temperatures remain below 0°C), adding an antifreeze agent to the cold water (hot water) system will increase anti-freezing effects. We recommend use of a proper antifreeze agent for this purpose, following consultation with the dealer where the unit was purchased.
In such cases as well, conduct either “water draining” or “pump antifreeze operation when heating operation is shut down.”
