oughly to remove all debris, chips and other foreign objects.
Failure to do so may make the assembly inoperable.
approved by ASSE (American Society of Sanitation
Engineers) to be installed in horizontal or vertical positions.
Local water authorities must approve all installation con-
figurations.
3. Allow sufficient clearance around the installed assembly
to conduct testing, servicing, and inspection. Allow a mini-
mum of 12" from the flood level to the bottom of the assembly.
4. Be sure to contact local code authorities for proper
installations.
5. If installing on fire protection system, be sure to purge air
from fire system. Fill system slowly with all inspectors test

NOTE: Ames assemblies require minimum maintenance. All
assemblies must be retested once maintenance has been
performed. Before servicing be certain shutoff valves are closed.
Removing Cam-Checks
1. Shut down water system and lock out system if possible.
Slowly open all ball valves to relieve air and water pressure.
Loosen bolts on groove coupler and remove groove coupler
and cover plate from valve body.
2. #1 CHECK (Fig. 2)
Using a 9/16" socket wrench or nut driver, remove the four
nuts from the #1 check studs (See fig.1). Using two hands,
place them at 12 o'clock and 6 o'clock, wiggle the check
assembly free. Remove through access port with back of
clapper first with spring end down. Pull check assembly out
of main body.
#2 CHECK (Fig. 3)
After loosening bolts with a 9/16" socket, remove bolts com-
pletely. Using the centerline access bar, spin the cam
assembly from the 9 o'clock position to the 12 o'clock posi-
tion, then (without letting go of the access bar) push the
cam assembly slightly downstream so that the clapper is
now parallel to the valve body. Now bring the cam assembly
through the check retaining wall. Leave the cam assembly
clapper parallel to the valve body. Pull the cam assembly
through the access port.
3. Using a
3/8" nut driver or a piece of small diameter pipe,
place on the cam arm torsion spring and move away from
and around the torsion spring retaining bracket so as to
relieve the torsion spring tension. (See Figure 4.) This will
allow the cam arm to move freely, enabling you to inspect
the clapper face and cam seat. Thoroughly clean the seat
area and clapper sealing surfaces, cam arms, and O-rings
for damage, nicks, and debris. If damaged, install a new
check assembly O-ring, or washer, shutoff disk.
4. Before reinstallation of check assembly, thoroughly clean O-ring
groove and lubricate O-ring with F.D.A. approved lubricant.
