　　In every 2000 hours, for clean dust of radiator surface, we open the hole cover of cooler on the bracket of fan, until it cleanlity. If it too dirty to clean it ,we can offload the cooler, spill the cooling oil and close the four entrance in case dirty into ,then blow with compressed air or wash it, finaly dry it.At the end ,installing it in formerly pleace.

Notice:do not use iron-bruse blow radiator in case damage the surface of radiator.

Let cooling water
The water in the air may coagulate in the air and oil separator .When exhaust temperature is lower than pressure dew point especially in wet air,there are separate out more cooling water .The oil contain too muchwater to makelubricating oil emulsification and affect machine safe operation,for instance:
Bad lubricate of compressor;
Bad effect or big errand of oil and air separator.
Arouse parts rust
So,we must make schedule of exhaust cooling water according to humidity.

The method of exhaust cooling water:
We should stop machine, without pressure of oil and air separator, sufficiency cooling and sufficiency deposition. For instance: before open the machine in the morning.
1.Open the pre-spiral of the bottom of oil and air separator
2.Slowly open the ball valve to exhaust water until the oil is pour then close the ball value.
3.close the pre-spiral of the ball value.

Safety value
The safety value was mixed before the whole set leaves the factory, so we do not advocate the user adjusts it .If need adjust that the users must is guide with the safety department or themselves maintenance man.

Advice of maintenance
We provide some maintenance advice to general users
1.Every week
a. Checking the unit to find out have or not strange voice and leakage
b. Checking the meter to see the reading if or not right
c. Checking the temperature display of
2.Every month
a. Checking the unit inside to look for the parts of rust or flexible. If found paint or tighten them.
b. Exhaust the cooling water.
3.Every three months
a. Clean out the dust of cooler surface, fan cover and fan leaves.
b. Filling the lubricant oil of electromotor bearing
c. Checking the tube to find if or not old or break
d. Checking the electricity component, clean out the control
box.

Filling the oil of the compressor
The oil level of compressor should keep between the lowest and the highest oil level under the running status. Too much oil could influence the separated effect. Too less oil could influence lubricate and cooling .In the period of changing oil. If the oil face is lower than the lowest oil level, the user should replenish lubricating oil in time .the method is:

1. Stop the machine and waiting the inside pressure is all release (affirming that the system does not pressure),then pulls down the power supply master switch.
2. Open the gob of the oil and gas separates and filing the cooling lubricating oil.
3. The change oil time after the machine normal operate according to the routine maintenance table.

Please use special environmental cooling oil of our company or appoint brand.
