PROCEDURE:
●Main water tank bracket
Remove 2 pieces bolts⑴ with 8# sleeve then take off the bracket⑵.
●Main water tank
①Thermostat
Check the opening temperature, full opening temperature and lift of the main valve in the thermostatic
heating equipment with adjustable temperature. If one of them does not meet the specified value, it should
be replaced. Or use a thermometer, water, heater, and container to test.
The initial opening temperature of the thermostat is 80～84℃, and the core moving 0.1mm can be regarded
as the initial opening. The full opening temperature is 95°C, and the core movement is greater than 3.5mm.
The simple test method is to put the core body into a high temperature resistant container, pour it into
boiling water and soak for a period of time, take out the core body with pliers, and observe whether the valve
can be fully opened. Until all closed.
②Add water cover
③Fan
Find a battery with sufficient power and connect the wires according to the positive and negative poles, and
check whether the fan draws air backwards.
●Main water tank maintenance
Compressed air with lower air pressure can be blown from the back to the water tank from a long distance to
clean up foreign objects on the surface. Or use a low-pressure water gun to spray the radiating fins from a
long distance to clean up foreign objects on the surface.
CAUTION:
●Cooling liquid is toxic. Avoid strictly eye or skin contact.
●Do not disassemble the hoop with too strong force. If not, it will cause permanent deformation and lose
elasticity, which will lead to leakage of cooling liquid.
