Installation Instructions

10 Service Valves

10.1 Open the Service Valves

WARNING: MODERATE TO SEVERE BURNS

Extreme caution should be exercised when opening the
Liquid Line Service Valve. Turn counterclockwise until
the valve stem just touches the rolled edge. No torque is
required. Failure to follow this warning will result in abrupt
release of system charge and may result in personal injury
and /or property damage.
Leak check and evacuation must be completed before opening the
service valves. The brazed lineset valves should be used for leak
checking and vacuuming. Using the separate suction port for this
process will result in loss of charge.
The Suction Service Valve must be opened fi rst BEFORE opening the
Liquid Service Valve.
1. Remove Service Valve Cap (Fig. 23).
2. Fully insert hex wrench into the stem and back out counterclockwise until
valve stem just touches the rolled edge (approximately five (5) turns.)
3. Replace the Valve Stem Cap to prevent leaks. Tighten finger tight plus an
additional 1/6 turn.
4. Repeat STEPS 1 - 3 for Liquid Service Valve.
