Air conditioner common leaking and maintenance methods in hopes it will help!

Leakage:

1, hanging in the machine setup is not level, common causes for the low right inside the machine left. Workaround: restart level adjustment fixed wall plate angle.

2. wall indoor unit connecting pipe out of the wall outside the hole low; workaround: back drilling (or reaming dressing) adjustment through wall angle, achieve high low.

3. wall indoor unit drain location below the through-wall holes location, resulting in condensation water cannot flow out. Workaround: increase the height of the wall plate.

4.a, indoor unit side (wall, floor standing) spend small drain angle; b, drain is too long, flowing smoothly; c, drainpipe is not smooth, wound; d, drain (hose) is extrusion; e, drains and broken, cracked; f, water drain outlet insert; g, drain fittings loose; h, drain dirty block objects. According to following respectively cause different maintenance treatment: a, resize the drain point; b, minimize the drain pipe length; c, rearrange the drain; d, finishing the drain (hose) is extruded parts; e, replace the drain; f, check out into the water drains; g, reconnect connector h, replace the drain or sewage fluoride liquid blow.

5. air conditioner indoor (3%, 4% above the evaporator hang-up) water used galvanized plate bending deformation or shedding. Solution: a, galvanized plate Assembly is not in place or falls off, reassemble b, galvanized plate bending deformation, the replacement of the galvanized sheet.

6 a, indoor refrigeration time wind Board drop; b, indoor and outdoor air humidity larger or indoor and outdoor temperature difference; workaround: a, can wind plate to the horizontal angle b, setting the wind speed is too low, indoor wind speed, it is set to medium-high wind.

7. indoor condensation in the Netherlands wind blowing out, resulting in a outlet. Solution: a, set the speed is too low, indoor wind speed, it is set to medium-high wind. B, paste the flannel, shell insulation.

8, indoor evaporator ice, caused by the leakage of ice. Solution: a system of deficiency, fluoridation; b, cleans the air duct system; c, wind speed, wind adjustment to normal.

9, indoor connection pipe connector with insulation wrapped are not in place, bare produced water condensation. Workaround: use the thermal insulation material is completely bare some connecting tubes.

10, interior-side connection pipe insulation layer is condensed water droplets produced outside of dripping water. Solution: a, insulation material adverse (sponge foam density is not enough, the material is too thin), thickening of the insulation layer or replace insulation; b, setting temperature too low, the wind speed is too low, so its indoor heat capacity of smaller, return gas pipe temperature is too low, the indoor temperature, humidity, long non-stop operation produces the above factors appropriate adjustments to improve; C, drainage pipe surface cooling, condensation water, plus the insulation layer.

11, hanging (cupboard, embedded) then the water plate cracks, water dish and open drainage connection. Solution: a, replace the water plate; b, bonding drainage pipe interface.

12, a, embedded indoor leakage; b, c; water level switch adverse, drainage pump motor; d, indoor low drainage plug did not install good; e, drain straight up more than 200 mm. Solution: install a, drainage approach, couldn't the drainage pipe bends is less than or close to 90 degrees or supposes bending too much, the drainage pipes with PVC pipe material; not embedded within the machine installation, resize the indoor unit level; b, bad water level switch (water level switch does not reset), replace the water level switch; c, drainage pump bad (motor coil open circuit, motor not running), the replacement of the pump motor; d, replace the drain plug; e, more than 200 mm straight up, causing water pump stops running water backflow, finishing pipeline so that the vertical distance is less than 200MM
