PREVENTIVE MAINTENANCE
Air Filter
Care must be taken to assure free ventilation of the Type
535A inasmuch as some of the components are operated at
dissipation levels such that excessive interior temperatures
will result without adequate air circulation. To assure free
passage of air the instrument must be placed so that the
air intake is not blocked and filter must be kept clean.
Moreover, the side panels and bottom cover must be in
place for proper air circulation. Do not remove the covers
except during maintenance.
A washable EZ KLEEN filter is used at the air intake
port of the instrument. Under normal operating conditions
the filter should be inspected and cleaned if necessary
every three to four months. More frequent inspection is
required when the operating conditions are more severe.
The following cleaning instructions are issued by the filter
manufacturer:
(1) If grease or dirt load is light, remove filter from in­
stallation and rap gently on hard surface to remove
loose dirt. Flush remaining dirt or grease out of filter
with a stream of hot water or steam.
(2) If load is too heavy for treatment described in (1), pre­
pare mild soap or detergent solution in pan or sink
deep enough to cover filter when laid flat. Agitate
filter up and down in solution until grease or dirt is
loosened and floated off.
(3) Rinse filter and let dry.
(4) Dip or spray filter with fresh Filter Coat or Handi-
coater.
These products are available from the local representative
of the Research Products Corporation and from most air
conditioner suppliers.
