Field Installation
Install the outdoor and indoor units per the manufacturer’s recommendations. Route the copper lines between the
units.
Installation Instructions
Attach the valve
using the mounting proce-
dure that best suits the
application. Clean the tubing
to be brazed to the Parker
frontseating valve.
Step 1
After brazing,
quench the joint with a wet
rag to cool the joint and
remove any flux residue.
Flux the copper
tubing and insert into the
stub. Flux is not required if a
low to zero-silver braze alloy
is used. Braze the joint. Due
to the extended copper stub
the valve does not need to
be immersed in water or
otherwise cooled during
brazing.
Install a valve
core (part #222034-4) and a
valve cap (part #221014-4B)
on the charge port.
The tubing should
be cut square, so it is round
and free of burrs at the con-
necting ends. Clean the tub-
ing to prevent contaminants
from entering the system.
Wrap a wet rag
around the copper stub
before brazing.
Flux the copper
tubing and insert into the
stub. (Flux is not required if a
low to zero-silver braze alloy
is used.) Braze the joint.
After brazing —
quench the joint with a wet
rag to cool the joint and re-
move any flux residue.
This is not a backseating valve. To open the valve
remove 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 incurs resistance.
Replace the valve cap finger tight then tighten an
additional 1/12 turn or 1/2 hex flat. A metal-to-metal seal is
now complete. Complete normal factory recommended
procedures.
