2. For the water purifier, the installation and replacement of filters must be carried out by
qualified personnel.
3. In case the machine is not in use for a long time, turn off the heating switch or the
refrigerating switch to save power.
4. In case the machine is not needed for a long time, please take off the plug, turn off the
copper chromeplated ball valve and drain off the remaining water through the outlet.
For another use, discharge water for 10 min. In the event that the machine is blocked by ice
due to the environment below ice point, keep the refrigerating switch closed for 4 hours and
then turn it on to continue the operation.
5. In case the water supply is cut off, please close the feed water ball valve and cut off the
power. After water re-supply, please open the other faucets to discharge sediment and then
turn on the feed water ball valve.
6. The machine must use an earthed three-pin socket and a reliable creepage protection
switch.
7. Never use organic solvents such as gasoline to clean the machine; strictly prohibit washing
the machine with water or splashing water to the machine.
8. Never turn on (off) the machine by inserting the plug into (pulling the plug out from) the
socket. Never increase the length of the supply cord to avoid fire.
9. If the supply cord is damaged, it must be replaced by the manufacturer or qualified person
so as to avoid a hazard.
10. The water source for the water purifier is civil tap water.
11. Never dismantle spare parts of the machine to avoid water leakage or damage.
3-5. Maintenance
12. Never turn the machine upside down or lean it more than 45° when moving it so as to
avoid any damage to it or any accident.

Check the PCB on the base plate.
Repair the machine and dry the
PCB, and then power on again.
Electric leakage Machine in poor contact
with ground
Use a three-pin socket with
earth wire, making the machine
grounded properly
Noisy operation Not installed steadily Place the machine on a steady
& solid surface
Machine fails to run Power supply not put through Switch on power supply
It is a normal state that the following circumstances occur when the water purifier is used.
1. During the heating, the heating tube may generate slight noises. This is a normal state.
2. When the heating tank is being heated without water, the anti dry-burning device will
disconnect automatically and can not reset by its own. The reset must be completed by a
professional technician. The design is in accordance with the national safety requirements.
3. When an ambient temperature is higher, the cooling capacity may be slower, which is a
normal state.
