7.2.1 Condenser
SIC-A series water chillers use the air cooled condenser with ferrule
installed openly, in the using time, it hard to avoid any dust and
sundries ,which will influence the heat emission effect, so it is
necessary to clean the condenser at fixed periods in order to keep its
working performance. Use brush, dust catcher or compressed air to
clean the wings and copper pipe. Then use the low pressure water to
cascade the tray pipe. Note: do not let the water to cascade on the
surface of the fan motor.
Note: 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 scurviness environment you had
see the situation to do the work. better
7.2.2 The evaporator
The inner flank of the heat emission pipe will pile up a great deal of
water incrustation after 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.
Open the pollution discharge porthole on the bottom of the
evaporator1,and spray rinse the heat emission pipe from the outer
flank to the innerflank, the water incrustation will be discharged from
the pollution discharge porthole.
