SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be
hazardous due to system pressure and electrical components. Only
trained and qualified service personnel should install, repair, or
service air-conditioning equipment.
Untrained personnel can perform basic maintenance functions of
cleaning coils and filters and replacing filters. All other operations
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

should be performed by trained service personnel. When working
on air-conditioning equipment, observe precautions in the litera-
ture, tags and labels attached to the unit, and other safety precau-
tions that may apply.
Improper installation, adjustment, alteration, service, mainte-
nance, or use can cause explosion, fire, electrical shock or other
conditions which may cause personal injury or property damage.
Consult a qualified installer, service agency, or your distributor for
information or assistance. The qualified installer or service agency
must use factory-authorized kits or accessories when modifying
this product. Refer to the individual instructions packaged with the
kits or accessories when installing.
Follow all safety codes. Wear safety glasses and work gloves. Use
quenching cloth for brazing operations. Have fire extinguisher
available. Read these instructions thoroughly and follow all warn-
ings or cautions attached to the unit. Consult local building codes
and applicable electrical codes for special installation require-
ments.
Electrical shock can cause personal injury or death. Before in-
stalling or servicing system, always turn off main power to sys-
tem. There may be more than one disconnect switch. Turn off
accessory heater power if applicable.
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 un-sweat remaining tubing stubs when neces-
sary. Oil can ignite when exposed to torch flame.
Failure to follow these procedures may result in personal inju-
ry or death.
