1, the wall-mounted internal unit is not installed horizontally, and the common reason is that the internal unit is low on the left and high on the right.

Solution:

Adjust the angle of the fixed hanging wallboard horizontally again.

2. The connecting pipe of the wall-mounted indoor unit is low in the wall hole and high outside;

Solution:

Re-drilling (or reaming and trimming) to adjust the angle of the wall hole, so that it is high inside and low outside.

3. The outlet position of the wall-mounted indoor unit is lower than the position of the through-wall hole, which makes the condensed water unable to flow out.

Solution:

Increase the height of hanging wallboard.

4a。 The inclination angle of the drainage pipe on the indoor machine side (wall-mounted, cabinet-mounted) is too small;

B, the drain pipe is too long, and the water flow is not smooth;

C. The drainage pipe is uneven and bent;

D, drain pipe (hose) is squeezed;

E. broken drainage pipes;

F. the outlet of the drain pipe is inserted into the water;

G, drain pipe joint is loose;

H. the drain pipe is blocked by foreign objects.

According to different reasons, the following maintenance treatments are carried out respectively:

A, readjust the angle of the drain pipe;

B, try to shorten the length of the drain pipe;

C, rearranging the drainage pipe;

D, install the extrusion part of the drainage pipe (hose);

E, replace the drain pipe;

F, take out the drain pipe and insert it into the water;

G. reconnect the connector h, and replace the drain pipe or blow fluorine liquid.

5. The galvanized sheet used for guiding water of indoor units of air conditioners (three-fold evaporator and four-fold evaporator hang up) is bent, deformed or falls off.

Solution:

A, galvanized sheet assembly is not in place or fall off, reassemble.

B, galvanized sheet bending deformation, replacement of galvanized sheet.

6.a. When the indoor unit of the air conditioner is cold, the air deflector drops water;

B, indoor and outdoor air humidity or indoor and outdoor temperature difference;

Solution:

A, the air deflector can be adjusted to the horizontal angle.

B, set the wind speed is too low, indoor wind speed is caused by low speed, and set it to medium-high wind speed.

7. The condensed water of the indoor unit is blown out by the wind wheel, which causes the air outlet to spray water.

Solution:

A, set the wind speed is too low, indoor wind speed is caused by low speed, and set it to medium-high wind speed.

B, paste the flannel insulation layer on the inner sleeve.

8. The indoor evaporator freezes, resulting in water leakage during deicing.

Solution:

A, the system is short of fluorine, and fluorine is added;

B, cleaning the air duct system;

C. If the wind speed is abnormal, adjust the wind speed to normal.

9. The insulation material at the interface of the indoor unit connecting pipe is improperly wrapped, resulting in condensed water at the exposed part.

Solution:

Completely wrap the exposed part of the connecting pipe with heat insulation material.

10. There are condensed water drops outside the insulation layer of the indoor connecting pipe, resulting in dripping.

Solution:

A, poor thermal insulation material (foam density of sponge is not enough, the material is too thin), thicken the thermal insulation layer or replace the thermal insulation material again;

B, the set temperature is too low, the wind speed is too low, which makes the heat transfer of the indoor unit smaller, the return air pipe temperature is too low, the indoor temperature is too high, and the humidity is high, which is caused by long-term non-stop operation. The above factors can be improved by appropriate adjustment;

C, drain pipe surface is too cold, produce condensate, can add insulation layer.

1 1 Wall-mounted (cabinet, embedded) water tray cracked, and the joint between the water tray and the drain tray stuck.

Solution:

A, replace the water tray;

B, glue the drain pipe interface.

12a, the embedded indoor unit leaks water;

B, poor water level switch;

C, drainage pump motor is broken;

D the drain plug at the lower part of the indoor unit is not installed;

E, vertical drainage pipe is greater than 200 mm ..

Solution:

A, improper handling of the installation drainage angle, the curvature of the drainage pipe should not be less than or close to 90 degrees, nor should it be set too large. The drainage pipe is made of PVC pipe; The embedded indoor unit is not installed horizontally, please readjust the level of the indoor unit;

B, poor water level switch (water level switch is not reset), replace the water level switch;

C. If the drainage pump is broken (the motor coil is open and the motor does not work), replace the drainage pump motor;

D, refitting the blockage;

E, vertical drainage pipe is greater than 200MM, when the pump stops running, it causes too much water backflow. Arrange the pipes so that the vertical distance is less than 200mm. ..
