GAA610-M ADVANCED EMISSION GAS MONITORING SYSTEM | OI/GAA610-M-EN REV. B
Analyzer air conditioner
Compressor
The compressor requires no maintenance. It is hermetically
sealed, properly lubricated at the factory and should provide
years of satisfactory operating service.
Should the refrigerant charge be lost, recharging ports (access
fittings) on the suction and discharge sides of the compressor
are provided for recharging and/or checking suction and
discharge pressures.
Under no circumstances should the access fitting covers be
loosened, removed or tampered with.
Breaking of seals on compressor access fittings during warranty
period will void warranty on hermetic system.
Recharging ports are provided for the ease and convenience of
reputable refrigeration repair service personnel for recharging
the air conditioner.
Inlet air filter
Proper maintenance of the inlet air filter, located behind the
front cover, will assure normal operation of the air conditioner. If
filter maintenance is delayed or ignored, the maximum ambient
temperatures under which the unit is designed to operate will be
decreased.
If the compressor's operating temperature increases above
designed conditions due to a dirty or clogged filter (or plugged
condenser coil), the air conditioner's compressor will stop
operating due to actuation of the thermal overload cut-out
switch located on the compressor housing. As soon as the
compressor temperature has dropped to within the switch's cut-
in setting, the compressor will restart automatically. However,
the above condition will continue to take place until the filter or
coil has been cleaned. It is recommended that power to the air
conditioner be interrupted intentionally when abnormally high
compressor operating temperature causes automatic shut-
down of the unit. The above described shutdown is symptomatic
of a clogged or dirty filter, thus causing a reduction in cooling air
flow across the surface of the compressor and condenser coil.
Note
•
Do not run the air conditioner for extended periods of time
with the filter removed. Particles of dust, lint, etc., can plug
the fins of the condenser coil which will give the same
reaction as a plugged filter. The condenser coil is not visible
through the filter opening, so protect it with a filter.
•
Continued operation under the above conditions can and will
damage and shorten compressor life. The air conditioner is
available with an easily removable inlet filter to facilitate
necessary cleaning. There should be no reason to neglect this
necessary maintenance.
Cleaning and changing the inlet air filter
Aluminum washable air filters are designed to provide excellent
filtering efficiency with a high dust holding capacity and a
minimum amount of resistance to air flow. Because they are
constructed entirely of aluminum, they are lightweight and easy
to service. To achieve maximum performance from your air
handling equipment, air filters should be cleaned on a regular
basis.
Filter removal and installation:
The inlet air filter is located behind the front access cover.
1. To access the filter, loosen the access-cover screw.
2. Swing top edge of access cover forward.
3. Slide air filter up and out of retaining tabs.
–
The filter may now be cleaned, or new filter installed.
Cleaning Instructions:
1. Flush the filter with warm water from the exhaust side to
the intake side. DO NOT USE CAUSTICS.
2. After flushing, allow filter to drain. Placing it with a corner
down will assure complete drainage.
3. Recoat the filters with RP Super Filter Coat adhesive.
When spraying filter do so from both sides for maximum
concentration of adhesive.
Note
It is recommended to exchange the filter once a year depending
on the environmental conditions!
Emptying the condensate collection bottle
CAUTION
Risk of injury due to corrosive condensates
Condensates are often corrosive.
•
When working with corrosive reagents note the hazard
information and safety precautions contained in the
applicable material safety data sheets.
•
Neutralize condensates and follow the prescribed
measures for disposal.
Empty the condensate collection bottle when the applicable
status message is displayed.
