pressure might exceed 0.7MPa. To control water pressure not exceeding 0.7MPa,
stabilizing valve shall be added in water input pipe of tap water to decrease water
input pressure.
Open the handle of safety valve periodically (one month or so) to see if there’s
any blockage, if so, please contact the authorized maintenance center for
replacement. Clean it according to the specification periodically (one year or so).
If need replacing safety valve, Gree safety valve with material code of
0738280101 shall be adopted, its pressure relief value is 0.7MPa±0.05MPa.
10.4 Maintenance of the Unit
(1) Check the water inlet and outlet for blockage periodically. If so, eliminate
it.
(2) Check the water circuits, pipe connectors and valves for blockage,
damage or leakage, and if the filter has been blocked by impurities.
10.5 Periodic Check for Electricity Leakage Protection
Switch
(1) For the unit whose power cord is self-equipped with electricity leakage, be
sure the electricity leakage protection switch before starting up is kept
“open”.
(2) After the electricity leakage protection switch is operating for a period
(normally one month), press “TEST” button under closed and energized
status to check if the protection switch performance is reliable (electricity
leakage protection switch shall cut off when pressing the TEST button
every time). If malfunction occur in the electricity leakage protection
switch, please replace or repair timely.
10.6 Safety Notices While Moving the Unit
(1) Before starting the compressor, make sure water pipe is connected safely
and water input of the water tank is completed, otherwise, malfunction
might occur.
(2) Unit wiring connection shall use the specified electric wire with correct
connection; wiring terminal shall not be directly affected by external force
and be reliably fixed. Improper connection or fixing might generate fire
hazard.
