30 minutes
Required Tools and Materials
 Small flat blade screwdriver
 3/8-inch open end wrench
 Needle nose pliers
 Sealant
 1/4-inch poly tubing
Prerequisites
 Valve ductwork free of debris
 Construction filters in place

NOTE:
Valves should be located so that they
do not come in contact with rigid
conduit, sprinkler piping, Greenfield
metal covering, or rigid pneumatic
tubing. Do not install valves tight against
concrete slabs or columns because
vibrations are amplified through these
structures. Also, allow clearance for
service access to controls.
