Bench Testing - Pentair Genesis HB16 Instruction Manual

BENCH TESTING

When "bench testing the HIBOY® air conditioner before mounting to the electronic enclosure, follow the
procedures outlined in the following paragraphs:
Make sure that the HIBOY® air conditioner is supported in a manner that assures free air flow out of and
back into the openings which are located in the base tray.
Refer to nameplate for proper electrical current requirements, then connect the power cord to a properly
grounded electrical outlet.
NOTE: Minimum circuit ampacity should be at least 125% of the amperage shown in the
DESIGN DATA table. To prevent overloading, no other equipment should be connected to this
circuit.
Make sure the unit has been in the upright operating position for at least five minutes.
Operate the air conditioner for five (5) or ten (10) minutes. No excessive noise or vibration should be
evident during this run period. The condenser blower located in the rear section of the air conditioner, the
evaporator or cool air blower located in the bottom of the unit, and the compressor should be running. To
check cool air output, use a reliable air temperature measuring device. The cool air should be between 50
F (10 C) and 60 F (16 C) when room temperature is between 70 F (21 C) and 80 F (27 C).
You may remove the air inlet filter while checking the operation. The discharge line from the compressor
(uninsulated line) should become very warm. Carefully touch this line to avoid possible burns. Condenser
air temperatures should be warmer than normal room temperatures within a few minutes.
Mounted along the side of the compressor is the suction accumulator which is insulated to help avoid
sweating or condensation buildup.
The compressor is provided with automatic reset thermal overload protection. This thermo switch is
located and mounted inside the plastic enclosure clipped to the compressor. The only time this switch
should operate is when the compressor overheats due to clogged or dirty inlet air filter, if ambient air
temperatures exceed nameplate rating or if enclosure dissipated heat loads exceed the rated capacity
of the air conditioner. The thermal overload switch will actuate and stop compressor operation. Blowers
will continue to operate, however, and the compressor will not restart until the compressor has cooled to
within the thermal overload cut-in temperature setting.

To avoid possible damage to the air conditioner, it must be in
an upright operating position for a minimum of five (5) minutes
before functional testing is started.
