Inspecting the Product

Pull out the power cord before inspecting the parts of the product.
5-1. Water Supply/Drain Pumps
1. Function
1) Supplying water to AG
: Water supply tank → Water supply pump → AG
2) Removing condensation water
: Condensation tank → Drain pump → Drain tank
2. Precautions
1) Water inlet should be under water.
2) Foreign substances: Gap between the impeller and the cover
is 0.6 - 1 mm. Make sure that no foreign substances of 0.5 - 1.2
mm enter the pump.
3) Rotating direction is fixed, so you need to connect the + and
- wires correctly.
4) Others: Noise may occur if you pull the water supply hose
and the air layer is formed inside the hose or if the pressure
inside the hose increases.
3. Potential Failures
1) Noise: Water supply tank 2. Precautions
2) Water inlet should be under water.
3) Foreign substances: Gap between the impeller and the cover is 0.6 - 1 mm. Make sure that
no foreign substances of 0.5 - 1.2 mm enter the pump.
4) Rotating direction is fixed, so you need to connect the + and - wires correctly.
5) Others: Noise may occur if you pull the water supply hose and the air layer is formed inside
the hose or if the pressure inside the hose increases. There is no water in the residual water
tank. Idling occurs due to the wrong connection of wires. Foreign substance is present in the
pump.
6) The component does not work: Terminal connection for water supply/drain pumps is incor-
rect. Foreign substance is present in the pump. Faulty component is used.
4. Things to Check in Case of Failure
1) Check the Precautions section first.
2) Measure the power consumption in the case of motor movement restriction - The value
should be below 200 mA.
3) Check the cycle in the case of impeller movement restriction - The value should be above
600 mm.
(Water should pour out from the hose connected to the water drain pump.)
4) Measure the resistance in the case of faulty motor - The resistance should be 20 Ω ± 5 %.
