CAUTION
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Filter drier must be wrapped in a heat---sinking material
such as a wet cloth while brazing.
Refer to Fig. 5 and install filter drier as follows:
1. Braze 5- -in. liquid tube to the indoor coil.
2. Wrap filter drier with damp cloth.
3. Braze filter drier to above 5" liquid tube. Flow arrow
must point towards indoor coil.

REFRIGERANT TUBING CONNECTION OUTDOOR
Connect vapor tube to fitting on outdoor unit vapor service
valves (see Table 1.) Connect and braze the 3/8" coupling
(provided with the filter drier) to the liquid service valve and
connect and braze the liquid tubing to the other end of this
coupling. Use refrigerant grade tubing.
SWEAT CONNECTION
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Service valves must be wrapped in a heat- -sinking
material such as a wet cloth.
Service valves are closed from factory and ready for brazing.
After wrapping service valve with a wet cloth, braze sweat
connections using industry accepted methods and materials.
Consult local code requirements. Refrigerant tubing and indoor
coil are now ready for leak testing. This check should include all
field and factory joints.
EVACUATE REFRIGERANT TUBING AND INDOOR
COIL
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Never use the system compressor as a vacuum pump.
Refrigerant tubes and indoor coil should be evacuated using the
recommended deep vacuum method of 500 microns. An alternate
triple evacuation method may be used if the deep vacuum
procedure is not followed.
IMPORTANT: Always break a vacuum with dry nitrogen.
