STRATUS TA20 Series Industrial Air Conditioners User Manual
1st edition RevA.
Preventative Maintenance
Air Filter Service
Before performing any maintenance, turn off power to the unit.
Note: This section applies to TA20-20-xx-xx units only. TA20-10-
xx-xx models have a filterless design.
Air conditioners require regular cleaning of the condensing
air inlet filter. Wash the filter often, and back-flush the
dirt out; or replace, if not washable, whenever it appears
physically dirty. Restriction to the flow of air over the condenser
coil will degrade the performance of the equipment, cause it to
overheat, reduce cooling and can damage the compressor.
The compressor protection system will cycle the unit off if
the condenser temperature is too high or the compressor is
otherwise overloaded.
Restricted air flow due to neglecting a dirty filter will cause the
unit to safety off and then turn back on after it cools off, over
and over (cycling). Operation in this overheat/shut down/cool
down/restart mode will damage the equipment and void the
warranty.
Remove the air conditioner filter and wash, or replace if not
washable. Dry thoroughly before replacing. Order replacement
filters by frame size (TA20-FILTER-1) from AutomationDirect.
DO NOT operate the air conditioner without the air filter,
except TA20-010-xx-xx models. Such operation will allow
the condensing coil to become dirty and lose efficiency,
causing overheating and diminished cooling capacity. Dirty
condensing coils must be back-flush cleaned using proper
commercial coil cleaning compounds and thorough back-
flush rinsing. Refer to directions on the cleaning compounds
selected. Acid wash is not recommended as it reduces the life
of the coil.
Note: Do not use solvents to clean the programmable thermostat.
Wipe with mild soap and water.
Condenser and Evaporator Fans:
STRATUS air conditioners use high efficiency, long life
(high duty cycle), high tech, ball bearing fans engineered for
optimum performance. The bearings are sealed and require no
maintenance. Keep fan blades clean for optimal performance.
Before performing any maintenance, turn off power to
the unit.
Fans are removable and powered through plug-in
connections.
Compressor
STRATUS uses hermetically factory sealed compressors that
are quiet, low vibration and are maintenance-free. Overheat
sensors are installed to protect the compressor from damage
due to overheating.
Note: The rotary compressor runs with compressed refrigerant gas on the
outer case and therefore is hot to the touch.
STRATUS air conditioners are meticulously leak-tested
and run-tested after assembly. If a leak in the system should
develop due to shipping damage or mechanical vibration, the
leak must be detected, repaired and the refrigerant charge
restored to the system by a qualified refrigeration professional.
Moving the Enclosure and the Air Conditioner
If the enclosure the STRATUS air conditioner is mounted to
must be moved, remove the air conditioner from the enclosure
and move the air conditioner and enclosure separately. Moving
an enclosure with the air conditioner mounted may damage
the enclosure and the air conditioner and void the warranties.
Replacement filters are available (purchase separately)
for each of the Stratus air conditioner frame sizes.
TA20-010-xx-xx units do not require filters.
