General Description
Topaz Portable Air Conditioners are designed to spot
cool industrial, commercial, institutional, and
construction sites. Six models provide 11,900 to 77,500
BTU/hr. Options include discharge nozzles to direct
conditioned air precisely where needed, and flexible duct
to transfer condenser hot air either outside or to an
adjacent area.
Topaz Portable Air Conditioners are completely self-
contained and housed within an insulated cabinet. The
unit’s exterior is constructed of galvanized steel and
protected with a tough powder-coated, polyester finish.
All models are equipped standard heavy-duty casters for
portability.
General Requirements
Topaz Portable Air Conditioners are designed for ease of
operation and rugged dependability. Follow installation
and maintenance instructions completely. Fill out and
return the warranty registration card within 30 days of
purchase to register the warranty.
Standard Features
Serviceability
Topaz Portable Air Conditioners have removable side
panels for easier servicing from all sides.
The interior of the unit is divided into four sub-
compartments. The upper right encloses the evaporator
coil and fan, and provides access to the thermostat and
fan switch. The lower right contains the condensate tank
and access to the high-pressure switch.
The condenser fan on air-cooled models can be found in
the upper left compartment. The lower left compartment
encases the condenser coil, compressor, and most
electrical components.
High-Pressure Safety Switch
All models feature a manual reset, high-pressure switch.
If refrigeration circuit pressure exceeds control limits,
power shuts off to protect the compressor and other
critical components.
Note: Wait four minutes to restart unit after high-
pressure safety switch trips.
Freeze Protection Control
The TZ-12AB, 24AB, 36AB, 60AB and 60AB4 models
are equipped with an automatic freeze protection control.
This control turns the compressor off if moisture on the
evaporator coil freezes and blocks the coil. Normal
cooling operation resumes when the temperature of the
coil rises and the ice melts.
Short Cycle Protection Timer
The TZ-12AB, 24AB, 36AB, 60AB and 60AB4 models
are equipped with a short cycle protection timer. The
timer provides a five-minute delay before the refrigerant
compressor restarts. Under normal conditions, no
adjustments are necessary.
