air inlet and 1.5 meters around the air outlet. If the air inlet
and the air outlet are blocked, the cooling ability that the
equipment should have cannot be realized.
a) Make sure that the water supply pipe of equipment is not
blocked;
b) It is necessary to check the water pipe and the water pump
to confirm that there is a proper amount of water entering the
water pump and exhaust it through the water pump exhaust
valve, otherwise it will cause damage to the water pump;
c) Confirm that the state of the equipment is normal and safe,
otherwise there may be injury and damage.
For equipment that has not been used for a long time, it may
be difficult to start the pump at the first start. Please gently
move the motor impeller before the equipment is powered on.
Please do not step on or sit on the equipment. Otherwise, it
may cause injury accidents such as falling or overturning
Clean the air filter at least once a week. If it is blocked, the
cooling ability will decrease and the power consumption will
increase, and the alarm will not work properly.
a) Please use cleaning agents that are non-corrosive to
metals and plastics;
b) Please keep the cleaning agent properly after cleaning to
prevent liquid leakage;
c) The container for storing the cleaning agent must be
sealed completely to avoid danger.
A temp sensor is installed inside the water inlet, and it is
forbidden to blow air inside the device with an air gun.
a) The sharp edges of the condenser fins may cut the skin;
b)The temperature of the internal compressor and refrigerant
piping is very high, and direct skin contact may cause burns.
a) When the ambient temperature is lower than 0℃ and the
machine is shut down for a long time, it is necessary to drain
the liquid and blow the water away in the system with
compressed air, otherwise there is a danger of freezing and
cracking the components and pipelines.
b) When room temperature is lower than 0 ℃ , it is
recommended to use antifreeze with a concentration of not
more than 30% containing ethylene glycol or propylene
glycol.
