General Description
Topaz Portable Air Conditioners are designed to spot
cool industrial, commercial, institutional, and
construction sites. These Two models provide 11,900 to
17,300 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 with 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 or register online at
www.gotopaz.com.
Standard Features
Serviceability
The only normal service required for Topaz Portable Air
Conditioners is the periodic replacement of the filters
and cleaning of the coil surfaces if they become dirty.
Both of these items can be accessed by removing the
inlet grills on the front and back of the unit. Pull on the
handle near the bottom of the grills; pull the bottom
away from the unit a few inches and lower the panel
until the tabs on top are clear of the casing and remove
the panel.
The condensate tank will need to be emptied on a
regular basis. The tank and the high pressure switch reset
can be accessed by sliding out the bottom drawer.
If more in-depth service is required, Topaz Portable Air
Conditioners have a hinged, latched door to access most
of the electrical controls including:
• Control voltage transformer
• Compressor and blower contactors
• Delayed start timer
• Float switch relay
Service ports for the refrigerant circuit can be accessed
through the access panel on the left side of the unit.
Access to any other component requires the removal of
the top and the left and/or right sides.
High- ressure 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 rotection Control
The TZ-12B and 18B 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 rotection Timer
The TZ-12B and 18B 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.
Manual Temperature-Control System
The manual temperature control system allows you to set
the desired temperature by simply rotating the
COOL/COOLER dial either left or right. The supply air
fan can be set to run continuously whether the cooling
circuit cycle is on and off, or can be set to cycle on and
off with the cooling circuit.
Filter
All units are equipped with removable disposable filters,
located behind the return air grilles for both the
condenser and evaporator coils. The filters should be
replaced when they are dirty. Filters should always be
installed when the unit is operating to keep the coils
clean and efficient.
Condensate Tank:
A five gallon polyethylene tank in the lower-front
compartment of the unit collects evaporator coil
condensate moisture. When full, a magnetic float
activates a relay that turns the refrigeration circuit OFF
and illuminates the condensate tank-full light on the
front of the unit. To empty the tank pull the front access
drawer open and remove the tank. Empty the tank,
replace it in the drawer with the molded handle facing
the front of the drawer and slide back in place, and
restart.
Note: The unit will not operate unless the tank is
drained periodically. An optional condensate pump is
available for continuous operation.
Optional Features
Condenser Duct
Condenser discharge air can be removed from the
conditioned space with flexible duct. Use 40-ft
maximum for all models. Allow six feet for every 90°
bend. Do not exceed 0.10-in wc external static pressure
at the condenser.
Ceiling- anel Duct Kit
A ceiling-panel duct kit comes complete with flexible
duct and a 2-ft by 2-ft ceiling-tile adapter which allows
condenser air to be vented to the plenum area above a
suspended ceiling.
Discharge Nozzle Kit
A dual-nozzle, discharge-air assembly optimizes the
ability to direct cool air precisely where needed. The
flexible nozzles are attached to a mounting plate that fits
over the evaporator-air grille. See Accessory
Information on page 11 for proper sizing.
Condensate ump
A condensate pump automatically drains the condensate
pan by removing evaporator-coil water allowing
continuous operation. The pump is connected to the
condensate drain and to the air conditioner’s power
supply. A hose runs from the unit to a convenient drain
or outdoor location.
Cord Kit (LCDI) (TZ-12B, 18B)
The LCDI cord set provides both personal shock as well
as cord arcing and fire protection. Use the LCDI cord
kit provided by TE P-AIR, Inc.

Installation Instructions
Before Installing
Check unit for damage. Air conditioners are inspected
at the factory. If any damage has occurred, save the
packaging and file a claim with the delivering carrier
within fifteen working days. TOPAZ requires minimal
installation. Plug unit in proper NE A receptacle, and
it begins to cool immediately.
Electrical Supply
Determine the proper power by checking unit’s rating
plate. Refer to the Specifications section on page 3 for
voltage and fuse requirements. Use wall outlets and
receptacles found in the table below.
Operating unit on improper voltages voids the warranty.
Note: Extension cords may be used if rated at a
minimum 120-V, 20-amp for models TZ-12B
and TZ-18B. Extension cords must be fitted with
the appropriate grounding-type attachment plug.
Use 25-ft maximum length extension.
Unit Operation
Fan
1. Place unit on level surface.
2. Plug unit in.
3. Press the COOL/FAN on switch for continuous fan
operation. The cooling circuit will cycle on and off.
Press the COOL/FAN AUTO switch for cycling the
fan operating on and off with the cooling circuit.
Cooling Cycle
1. Set the desired temperature by adjusting the
COOL-COOLER dial from 68º-115º
Note: Wait 4 minutes between turning cooling mode
off and on.
reventative Maintenance
TOPAZ provides maximum performance and reliability
with minimum maintenance. The refrigeration and
electrical circuits of the system should be serviced by
qualified technicians only. To prolong the life of the
unit, perform regular maintenance as described below.
Blower Motors
The blower motor has permanently lubricated ball
bearings and requires no relubrication. Inspect fan for
buildup of dirt on blades. Clean as needed.
Filters
Dirty filters cause the unit to operate at reduced
efficiences. Inspect both evaporator and condenser air
filters every six weeks, or more, if operating in a dirty
environment. The filters are located behind the air inlet
grilles on the front and back of the unit. Remove the
grilles by pulling the bottom of each grill outward
using the handle located near the bottom of the panels.
When the bottom of the panel is clear of the unit
casing, it can be lowered several inches, which will
disengage tabs at the top of the panel from slots in the
casing. At this point the panel can be removed. The
filters are visible at this point but still retained by four
clips. Use a screwdriver to loosen the screws securing
the clip, so the clips rotate downward, clear of the filter.
Remove the filter and replace with a clean one
reversing the above procedure.
Do not operate the unit without filters. Doing so will
cause the coil to become dirty faster, and may require
professional cleaning.
Coil Cleaning
Evaporator and condenser coils can be cleaned using
compressed air.
Condensate ump
1. Disconnect unit from power source before
attempting to service or remove any component.
2. Be sure floats move freely. Clean as necessary.
3. Remove floats and check for obstructions. Clean as
needed.
4. Clean tank with warm water and mild soap when
mineral deposits are visible.
