Figure 1 - Installing Refrigerant Lines
3
Field Installation:
Install the outdoor and indoor units
per the manufacturer’s recommendations.
Route the copper lines between the units.
Step 1:
The tubing should be cut
square. Make sure it is round
and free of burrs at the con-
necting ends. Clean the tub
-
ing to prevent contaminants
from entering the system.
Step 3:
Flux the copper tube and in
-
sert into the stub. Braze the
joint. No flux is necessary if a
low to zero-silver braze alloy
is used.
Step 5:
This is not a back seating
valve. To open the valve re-
move the valve cap with an
adjustable wrench. Insert a
3/16” or 5/16” hex wrench into
the stem. Back out counter-
clockwise until the valve stem
just touches the retaining
ring.
Step 2:
Wrap a wet rag around the
copper stub before brazing.
Step 4:
After brazing, quench with a
wet rag to cool the joint and
remove any flux residue.
Evacuate, purge or charge
the connecting lines per the
unit manufacturer’s instruc
-
tions.
Step 6:
Replace the valve cap finger
tight then tighten an addi
-
tional 1/12 turn or 1/2 hex flat.
A metal-to-metal seal is now
complete. Complete normal
factory recommended proce-
dures.
