ATTENTION:

Jomar requires that the Add-A-Valve® installer view the Jomar installation video prior to attempting

installation. Failure to do so will relinquish Jomar from any and all liability for improperly installing

an Add-A-Valve® device. In this case, Jomar will not be responsible, nor will it exchange or provide a

refund for any improperly installed Add-A-Valve®.

Video is available for viewing on the Jomar website at: www.jomarvalve.com/aav.html

NOTE: The Jomar Add-A-Valve® is engineered for ONE-TIME use as an emergency shut-o󱐯

device! Once the stem cutter has been raised, DO NOT lower it again.

Step 4

Assemblethetwobodyhalves

aroundthecoppertubing.

NOTE: Be sure the stem cutter is

backed out all the way so that the

cutter does not make contact with

the copper tubing.

Step 5

Usingaratchetandwrench, tighten the four (4) 316 stainless steel bolts in an ‘X’

pattern to a torque of 95 - 105 in/lb.Donotovertighten,asyoumaystripthebolts

detected,makesurethegapisevenlydistributedonbothsidesofthebody.

NOTE: A closed gap on one side and an open gap on the other will cause a leak.

Additionally, it will prevent the cutter from making a straight cut and will damage

the pipe, thereby making it susceptible to breakage or a leak.

Ensureevengap

directions.

CORRECT INCORRECT

Unevengapdistribution

canleadtoinstallfailure.

Step 10

When the stop ring is reached, the seating position of the valve is met. At this time, ratchet

approximately one to one and a half turns to expand the Viton® seal across the two pipe cuts.
