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.

CAUTION
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.
