SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service,
maintenance, or use can cause explosion, fire, electrical shock,
or other conditions which may cause death, personal injury or
property damage. The qualified installer or agency must use
factory-authorized kits or accessories when modifying this
product.

Follow all safety codes. Wear safety glasses, protective
clothing, and work gloves. Use quenching cloth for brazing
operations. Have fire extinguisher available. Read these
instructions thoroughly and follow all warnings or cautions
included in literature and attached to the unit. Consult local
building codes and the current editions of the National
Electrical Code (NEC) ANSI/NFPA (American National
Standards Institute/National Fire Protection Association) 70. In
Canada, refer to the current editions of the Canadian Electrical
Code CSA (Canadian Standards Association) C22.1.

Understand the signal words — DANGER, WARNING,
and CAUTION. DANGER identifies the most serious hazards
which will result in severe personal injury or death.
WARNING signifies hazards that could result in personal
injury or death. CAUTION is used to identify unsafe practices,

which would result in minor personal injury or product and
property damage.

Recognize safety information. This is the safety-alert
symbol ( ). When this symbol is displayed on the unit and in
instructions or manuals, be alert to the potential for personal
injury. Installing, starting up, and servicing equipment can be
hazardous due to system pressure, electrical components, and
equipment location.

WARNING

Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation. There
may be more than one disconnect switch. Tag all
disconnect locations to alert others not to restore power
until work is completed.

WARNING

When installing the equipment in a small space, provide
adequate measures to avoid refrigerant concentration
exceeding safety limits due to refrigerant leak. In case of
refrigerant leak during installation, ventilate the space
immediately. Failure to follow this procedure may lead to
personal injury.

WARNING

DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.

To remove a component, wear protective gloves and
goggles and proceed as follows:

a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from

system using both high-pressure and low pressure
ports.

c. Traces of vapor should be displaced with nitrogen

and the work area should be well ventilated.
Refrigerant in contact with an open flame produces
toxic gases.

d. Cut component connection tubing with tubing cutter

and remove component from unit. Use a pan to catch
any oil that may come out of the lines and as a gage
for how much oil to add to the system.

e. Carefully unsweat remaining tubing stubs when

necessary. Oil can ignite when exposed to torch
flame.

Failure to follow these procedures may result in personal
injury or death.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Design Revision

DO NOT re-use compressor oil or any oil that has been
exposed to the atmosphere. Dispose of oil per local codes
and regulations. DO NOT leave refrigerant system open to
air any longer than the actual time required to service the
equipment. Seal circuits being serviced and charge with
dry nitrogen to prevent oil contamination when timely
repairs cannot be completed. Failure to follow these
procedures may result in damage to equipment. For
information about replacement oil type and viscosity, see
the Installation, Start-Up, and Service Instructions for the
38VMAH and 38VMAR outdoor units.

GENERAL

packaged for shipment to avoid damage during normal transit
and handling. It is the receiving party’s responsibility to inspect
the equipment upon arrival. Any obvious damage to the carton
and/or its contents should be reported on the bill of lading and a
claim should be filed with the transportation company and the
factory. Unit should always be stored in a dry place, and in the
proper orientation as marked on the carton.

To avoid equipment damage, do not lift unit by the drain
pipe or refrigerant piping. Unit should be lifted using the
mounting brackets.

After determining the condition of the carton exterior,
carefully remove each unit from the carton and inspect for
hidden damage. Check to make sure that items such as
thermostats, controller etc. are accounted for whether packaged
separately or shipped at a later date. Any hidden damage
should be recorded, a claim should be filed with the
transportation company, and the factory should be notified. In
the event a claim for shipping damage is filed, the unit,
shipping carton, and all packing must be retained for physical
inspection by the transportation company. All units should be
stored in the factory shipping carton with internal packaging in
place until installation.

PROTECTING UNITS FROM DAMAGE — Do not apply
force or pressure to the coil, piping, or drain stub-outs during
handling. All units should be handled by the chassis or as close
as possible to the unit mounting point locations.

The unit must always be properly supported. Temporary
supports used during installation or service must be adequate to
hold the unit securely. To maintain warranty, protect units
against hostile environments (such as rain, snow or extreme
temperature), theft, vandalism, and debris on jobsite.
Equipment covered in this manual is not suitable for outdoor
installations. Do not allow foreign material to fall into drain
pan. Prevent dust and debris from being deposited on motor,
fan wheels and coils. Failure to do so may have serious adverse
effects on unit operation and in the case of motor and blower
assembly, may result in immediate or premature failure. Failure
of any unit caused by deposits of foreign material on the motor
or blower wheels will not be covered by the manufacturer’s
warranty. Some units and/or job conditions may require some
form of temporary covering during construction.

PREPARING JOBSITE FOR UNIT INSTALLATION —
To save time and to reduce the possibility of costly errors, set

up a complete sample installation in a typical room at jobsite.
Check all critical dimensions such as pipe, wire, and duct
connections requirements. Refer to job drawings and product
dimension drawings as required. Instruct all trades in their
parts of the installation. Units must be installed in compliance
with all applicable local code requirements.

IDENTIFYING AND PREPARING UNITS — Be sure
power requirements match available power source. Refer to
unit nameplate and wiring diagram. In addition:

• Check all tags on unit to determine if shipping screws are

to be removed. Remove screws as directed.

• Rotate the fan wheel by hand to ensure that the fan is

unrestricted and can rotate freely. Check for shipping

damage and fan obstructions. Adjust blower motor as

required.
