SAFETY CONSIDERATIONS
Installing, starting up, and servicing air-conditioning components
and equipment can be dangerous. Only trained, qualified installers
and service mechanics should install, start up, and service this
equipment.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Service Instructions

When working on the equipment, observe precautions in the liter-
ature and on tags, stickers, and labels attached to the equipment.
Page
Follow all safety codes. Wear safety glasses and work gloves.
.
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.
.
Use care in handling, rigging, and setting bulky equipment.
Personal injury could result.
.
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.
.
DO NOT re-use compressor oil or any oil that has been ex-
posed 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 com-
pleted. Failure to follow these procedures may result in dam-
age to equipment.
