(3) Maintenance of the strainer (once a month)
Caution
If the mesh of the Y-shaped strainer becomes clogged with foreign matter such as algae, the
exhaust heat performance will be reduced, which may trigger the safety device, stopping the
operation.
Warning
Stop the facility water device or shut off the facility water circuit, and release the residual
pressure before cleaning the strainer.
Stop supplying the facility water, and conduct maintenance after removing the mesh of the Y-shaped
strainer.
If foreign matter is accumulated, clean the mesh with a brush or air gun in order to avoid deforming or
damaging it.
[Key point]
Installation of a valve and a pressure gauge is recommended to clean the Y-shaped strainer easily.
If this is done, it will not be necessary to stop the facility water device by mounting a valve and fully closing
it when cleaning the Y-shaped strainer.
The pressure of the facility water circuit can be checked and cleaning can be performed easily by
mounting a pressure gauge.
(4) Cleaning of the facility water equipment (once every three months)
•
Clean the facility water equipment and replace the facility water.
•
The supplied facility water should be within the range shown in Table 2.
(5) How to clean the water-cooled condenser
Even if the facility water quality is controlled carefully, the inside of the water-cooled condenser will
become dirty with scale, leading to a decrease in performance. If the performance decreases, the
temperature difference at the cooling water inlet and outlet will be smaller, and the condensation pressure
will be higher than usual (if the inlet conditions of the compressed air are the same).The procedure for
cleaning the water-cooled condenser is as follows.

Chemical cleaning
Chemical cleaning is divided into two methods, static method and circulating method. The latter is more
effective. When performing chemical cleaning, beware of hazardous gases being generated and corrosion
by the cleaning liquid.
