A. GENERAL
This information is intended for use by individuals
posses-
sing adequate
backgrounds
of electrical and mechanical
experience. Any attempt to repair a central air conditioning
product may result in personal injury and or property
damage. The manufacturer
or seller cannot be responsible
for the interpretation
of this information, nor can it assume
any liability in connection with its use.
The following instructions
cover 4TFR4 Condensing
Units.
NOTE:
These outdoor
units are designed to be installed with
approved/matched
Trane indoor systems.
These units use R-410A refrigerant
which operates at 50 to
70% higher pressures than R-22. Use only R-410A approved
service equipment. Refrigerant cylinders are painted a
"Rose" color to indicate the type of refrigerant
and may
contain a "dip" tube to allow for charging of liquid refriger-
ant into the system. All R-410A systems use a POE oil that
readily absorbs
moisture from the atmosphere.
To limit this
"hygroscopic"
action, the system should remain sealed
whenever possible. Never break a vacuum with air and
always change the driers when opening the system for
component replacement.
Check for transportation
damage after unit is uncrated.
Report promptly,
to the carrier,
any damage found to the unit.
To determine
the electrical
power requirements
of the unit,
refer to the nameplate
of the unit.
The electrical
power
available
must agree with that listed on the nameplate.
