5 FT. ABOVE UNIT-UNRESTRICTED
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
refrigerant 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 alwayA 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.

(* latest revision number).
3. The support pad must NOT be in direct contact with any
structure.
Unit must be positioned a minimum of 12"
from any wall or surrounding
shrubbery to insure
adequate airflow. Clearance must be provided in front of

VALVE OPERATION
BRASS LiQUiD LiNE SERVICE VALVE
The Brass Liquid Line Service Valve is factory shipped in the
seated position to hold factory charge. The pressure tap
service port (when depressed) opens only to the field brazing
side of the valve when the valve is in the seated position.
The liquid line valve is not a back seating valve (see
WARNING below).
Extreme caution should be exercised when opening the
Liquid Line Service Valve. Turn valve stem counterclock=
wise only until the stem contacts the rolled edge. (See
Figure 3) No torque is required.
BRASS GAS LiNE SERVICE VALVE
The Brass Gas Line Service Valve is shipped in the closed
position to hold the factory refrigerant
charge. The pressure
tap service port (when depressed) opens only to the field
brazing side when the valve is in the closed position. The Gas
Line Service Valve is full open with a 1/4 turn. See Figure 4.
BRAZING REFRIGERANT LINES
1. Remove lower access cover to access service valves.
The gas line must always be insulated.
2. Before brazing, remove plugs from external eopper stub
tubes. Clean internal and external surfaces of stub
tubes prior to brazing.
