CARBON MONOXIDE POISONING HAZARD
Special Warning for Installation of Furnace or Air Handling Units in
Enclosed Areas such as Garages, Utility Rooms or Parking Areas
Carbon monoxide producing devices (such as an automobile, space
heater, gas water heater, etc.) should not be operated in enclosed areas
such as unventilated garages, utility rooms or parking areas because of
the danger of carbon monoxide (CO) poisoning resulting from the exhaust
emissions. If a furnace or air handler is installed in an enclosed area such
as a garage, utility room or parking area and a carbon monox i de produc ing
device is operated therein, there must be adequate, direct outside
ventilation.
This ventilation is necessary to avoid the danger of CO poisoning which
can occur if a carbon monoxide producing device continues to operate in
the enclosed area. Carbon monoxide emissions can be (re)circulated
throughout the structur e if the furnace or air handle r is operating in any
mode.
CO can cause serious illness including permanent brain damage or death.

This ceiling mount air handler is available in cooling capacities of 1.0, 1.5, 2, 2.5, 3.0, 3.5, 4.0 and 6.0 nominal tons of
cooling. Electric heat models are available in capacities of 0,
5, 6, 8 and 10 kW.
The unit is designed to be installed in a horizontal position
above a dropped ceiling. Do NOT install this unit outside
the structure. These models are designed for INDOOR
USE ONLY.
PRE-INSTALLATION CONSIDERATIONS
Carefully read all instructions for the installation prior to installing product. Make sure each step or procedure is understood and any special considerations are taken into account
before starting installation. Assemble all tools, hardware
and supplies needed to complete the installation. Some items
may need to be purchased locally. Make sure everything
needed to install the product is on hand before starting.
Before attempting any installation, the following points should
be considered:
• Structural strength of supporting members
• Clearances and provision for servicing
• Power supply and wiring - Routing of wires must be
arranged so the control board cover is fixed properly.
If not, a possibility of overheating, fire or electrical
shock may occur at the connection point of the terminal.
• Air duct connections - Ductwork should be fabricated
in accordance with local codes and sized to accommodate 375-425 CFM per ton of cooling with the static
pressure not to exceed 0.5” W.C. Inadequate ductwork
that restricts airflow can result in improper performance
and compressor or heater failure.
• Drain facilities and connections
• Installation of unit must be, at a minimum, of 91” (2.3m)
above the floor.

2. The connecting pipe should not be installed until the indoor and outdoor units are installed. The connecting
pipe should be kept dry during the installation operation.
3. If additional refrigerant is added, record the amount and
retain a copy for future maintenance.
Connection of piping
All field piping must be provided by a licensed refrigeration
technician and must comply with the applicable local and
national codes.
1. Measure the necessary length of the connecting pipe,
following the instructions below. Connect the indoor unit
first and then the outdoor unit.
• Carefully bend the tubing as shown below.
Bend the pipe with the thumbs

Figure 17
• Daub the surfaces of the flare pipe and the joint nuts
with refrigeration oil. Rotate it 3 to 4 rounds with your
hands before fastening the flare nuts.
Use
Refrigeration oil
Figure 18
• Always use two (2) wrenches simultaneously when
you connect or disconnect the pipes.
Marking the ends
Figure 19
• Make sure the stop valve of the outdoor unit is closed
completely. When loosening it for connecting, first
loosen the nuts on the stop valve. Connect the flare
pipe immediately (within 5 minutes) to prevent dust
and debris from contaminating the system. Always
expel the air from the pipes with refrigerant before connection.

Page 11
• Expel the air after connecting the refrigerant pipe with
the indoor and outdoor units. Fasten nuts at the repair points.
• Bend the connecting pipe of small wall thickness.
Cut out a desired concave at the bending part of the
insulating pipe. Cover exposed portions of the pipe
with tape after bending to prevent impurities from entering.
Bend the connecting pipe of small wall thickness.
Cut out a desired concave at the bending part of the
insulating pipe.
To prevent collapsing or deforming, bend the pipe at
its biggest radius.
Use a bender to get small radius pipes.
NOTES: The bending angle should not exceed 90°
The middle of the pipe is the best place to bend, since
a large bending radius is preferable.

Leak Testing (Nitrogen or Nitrogen-Traced)
Pressure test the system, using dry nitrogen and soapy water
to locate any leaks in the system. If you wish to use a leak
detector, charge the system to 10 psi using the appropriate
refrigerant, then use nitrogen to finish charging the system
to working pressure. Apply the detector to suspect areas. If
leaks are found, repair them. After repair, repeat the pressure test. If no leaks exist, proceed to System Evacuation.
Insulation
Cover all exposed parts of the flare pipe joints and refrigerant
pipe on both the liquid and gas sides, with insulating materials. Incomplete coverage may cause water condensation.
CONNECTING THE AIR HANDLER TO THE
OUTDOOR UNIT
To receive optimum throttle efficiency, mount the orifice as
level horizontally as possible. Anti-shock rubber should be
wrapped on the external parts of the orifice to reduce noise.

CONNECTING THE DRAIN PIPE - INDOOR UNIT
Purchased from your dealer, polyethylene tubing can be used
as the drain pipe (outside diameter 1” - 1/10” (29-31mm);
(inside diameter 1” or 25mm).
To prevent water from ingressing into the air conditioner when
the air conditioner is not operating, the drain pipe should be
slanted down toward the outdoor (outlet side) at a degree of
over 1/50. Avoid any bulges or water deposits.
Take care not to put undue stress on the drain pipe when
connecting to prevent its pulling away from the body. One
support point should be set every 39” - 59” (1-1.5m) to help
support the drain pipe and prevent it from pulling. The drain
pipe can also be tied to the connecting pipe for support.
If the drain pipe is long, tighten the indoor part with a sealant
to prevent its loosening.
If the drain pipe’s outlet is higher than the body’s pump joint,
arrange the pipe as vertically as possible, with the left distance less than 8” (200mm). Otherwise, the water will over-
flow when the air conditioner ceases operation. Only avail-
able with units with plugs.
The end of the drain pipe should be over 2” (50mm) higher
than the ground or the bottom of the drainage chute. Do not
immerse it in water. If water is discharge directly into sewage, make a U-form aqua seal by bending the pipe up to
prevent odorous gases from entering the home through the
drain pipe.
Drain Pipe Installation for the unit with pump: Figure 25.
