OPERATION
Ambient temperature
Temperature 0-35°C
Atmosphere 86-106 kpa
VOLTAGE:115V/60HZ
Position the water cooler on the horizontal, structurally sound ground. Leave an
adequate open space (10-20 cm) behind the water cooler for good ventilation.
When using the bottles holding ultra-pure water, distilled water or space water with
the so-called clever lid, tear off the hygienic labels on the lid.Place the bottles at the
intake, then the core of water guard will automatically open the valve and seal it in
the meantime, when moving the bottles, the valve will also seal automatically to
avoid any possible oozing.
Push the hot water valves, bubbles are generated inside the bottle, indicating
that water is flowing into hot water and cold water tanks,keep pressing the hot water
valve until water flows out,dispensing cold water required need no particular
adjustment.
Caution: Do no connect the electrical power plug,until water comes out of the hot
water tap.
After water is flowing out from the hot tap; power can be on, the yellow LED indicator
on the front light on.
Turn the heating switch on, the red LED indicator on the front lights on and the
heating system starts working, when the hot water comes up (86-95°C) or so, the
red light goes off, the heating system stops working is on a warm keeping status.
When the hot water temperature is lower than 85°C, the heating system will resume
working again automatically.
Turn on the cooling switch, the green LED indicator on the front lights on and the
cooling system starts working when the cold water falls down to 5-15°C (for
compressor-cooling)
，
the green light goes off, the cooling system stops working
and is on a cold keeping status.When the cold water temperature goes up to a set
degree, the cooling system will resume working again atomically.
Since the temperature has already been adjusted before leaving the factory, it is
unnecessary for customer to set the temperature.
Turn the heating, cooling water switch on.Then the heating and cooling processes
start working, the heating indicator is red showing it is heating. When the hot water
temperature reaches the set limit, the heating process starts working automatically.
When cooling is lit green, the cold water starts working. The cooling indicator goes
out as the temperature of the cold water and fridge get the set lower limit. The
cooling process stops working,when the cold water temperature gets the set upper
