Method For Cleaning Air Conditioner Condenser - Komatsu H70051 Series Operation & Maintenance Manual

MAINTENANCE PROCEDURE

METHOD FOR CLEANING AIR CONDITIONER CONDENSER

• Do not use a steam cleaner for the cleaning since it is dangerous as the condenser is heated.
• If the pressurized water hits a person directly or dirt scatters by using pressurized water, there is a
danger of personal injury.
Wear the protective equipment such as the protective eyeglasses and dust mask.
If dirt or dust is stuck to the condenser, clean them by using water.
If water pressure is excessive, the fin may be deformed. So cleaning by using pressurized water must be done
from a sufficiently distant position.
1.
Open the engine side covers (1) and (2) on the right and
left sides of the machine.
2.
Remove the mounting bolts (4) of condenser (3) (2 places
each on the right and left).
3.
Hold the top of the condenser (3) and tilt it backward.
A gap is made between the condenser (3) and radiator (5).
4.
Clean the condenser with water through this gap.
5.
Restore the condenser (3) to the original position and in-
stall it with the mounting bolt (4).
6.
Close the engine side covers (1) and (2) on the right and
left sides of the machine.
