10.1 Open the Service Valves

WARNING: MODERATE TO SEVERE BURNS
Extreme caution must 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.

valve stem just touches the rolled edge (approximately five (5) turns).
3. Replace the Valve Stem Cap to prevent leaks. Finger tighten plus an additional
1/6 turn.
