6.2 Components Maintenance
6.2.1 Condenser
The air-cooled tube-fin style condenser of the SIC-A series is installed in an open
way. In the use process, it will inevitably adhere to dust and sundries, which
reduces the heat exchange rate. The condenser should be cleaned regularly so
that the machine can run stably. Use a brush, dust collector or compressed air to
clean the dust and sundries on the condenser fins and copper pipe, and then use
low-pressure water to spray the coil from the top to bottom or from inside to outside.
Be careful not to sprinkle water on the fan motor.
Attention!
Do the cleaning work every half-year in the environment with little dust, but
you must do the work every month in the environment with a great deal of
dusts, and under the severe environment you had better see the situation
to do the work.
6.2.2 Evaporator
The inner flank of the heat emission pipe will pile up a great deal of water
scaleafter a long time use of the evaporator, which will influence the heat emission
effect, so it is necessary to clean the evaporator at fixed periods in order to keep its
working performance. If the circulation has been under water treatment, it is
advised that firstly use hydrogen peroxide to kill bacteria and then use a high
pressure water rifle to flush it, at last check whether there is still scalescale. If the
circulation is not processed under water treatment, clean it with citric acid and
sulfamic acid along with inhibiter, and then flush it with a high pressure water rifle.
Passivation is need after acid washing, and the dirt will be diacharged from the
water outfall.
