Cut off all temporary power supply, resume all the insurance and check the electricity for the last time.
Check the power supply and voltage of the control circuit; _____V must be ±10% within the range of rated
operating power.

21. Daily Operation and Maintenance
In order to avoid damage of the unit, all protecting devices in the unit had been set before delivery, so please do
not adjust or remove them.
For the first startup of the unit or next startup of unit after long-period stop (above 1 day) by cutting off the power,
please electrify the unit in advance to preheat the unit for more than 8 hours.
Never put sundries on the unit and accessories. Keep dry, clean and ventilated around the unit.
Remove the dust accumulated on the condenser fin timely to ensure performance of the unit and to avoid stop
of the unit for protection.
In order to avoid protection or damage of the unit caused by blockage of the water system, clean the filter in
water system periodically and frequently check water replenishing device.
In order to ensure anti-freezing protection, never cut off the power if ambient temperature is below zero in winter.
In order to avoid frost crack of the unit, water in the unit and pipeline system not used for a long period should
be drained. In addition, open the end cap of the water tank for drainage.
When the water tank has been installed but the water tank is set to “Without”, functions relative with the water
tank will not work and the displayed water tank temperature will always be “-30”. In this case, the water tank would
suffer frostbite and even other severe influences under low temperature. Therefore, once the water tank has been
installed, the water tank must be set to ‘’With”, otherwise GREE will not be responsible for this abnormal operation.
Never frequently make the unit on/off and close the manual valve of the water system during operation of the
unit by users.
Ensure frequent check to the working condition of each part to see if there is oil stain at pipeline joint and charge
valve to avoid leakage of refrigerant.
If malfunction of the unit is out of control of users, please timely contact with authorized service center.
The water pressure gage is installed in the returning water line in the unit. Please adjust the hydraulics system
