VALVE/TRIM INSTALLATION
1. Make sure the trim drawing matches the system’s requirements.
CAUTION
Make sure the foam spacer is removed from
inside the valve body before attempting to
install the valve.
Failure to follow this instruction could cause
improper valve operation, resulting in personal
injury and/or property damage.
•
2. Remove all plastic caps and foam spacers from the valve.
3. Apply a small amount of pipe joint compound or Teflon* tape to
the external threads of all threaded pipe connections. DO NOT get
any tape, compound, or other foreign material into the valve body,
pipe nipples, or valve openings.
CAUTION
Make sure no foreign material gets into the valve body, pipe
nipples, or valve openings.
If using any material other than Teflon tape, use extra caution
so that no material gets into the trim.
Failure to follow these instructions could cause improper valve
operation, resulting in personal injury and/or property damage.
