1
. Inspect shippin

e, valve, linka
g
e, and actuator
f
or physical
damage. If shipping damage has occurred notify appropriate carrier. Do
n
ot install.
2
. I
f
a replacement, remove existing valve, linkage and actuator
f
rom the
pi
p
i
ng system.
3
. If actuator and linka
g
e are removed, they must be reinstalled correctly.
T
he actuator must be rotated so that the valve sits
p
ro
p
erl
y
for close off.
4
. Install valve with the
p
ro
p
er
p
orts as inlets and outlets. Check that inlet
a
nd outlet of 2-wa
y
valves are correct; check that the "A","B", and "AB"
p
orts of 3-way valves are piped correctly for mixing or diverting. See
supplied drawings on previous page
.
5. Blow out all pipin
g
and thorou
g
hly clean before valve installation.

C
lean male pipe threads with wire brush and rag. If threads have been

C
lean pipes, threads, and valve threads before
i
nstallation; check
f
or any
f
oreign material that can become lodged in trim
c
omponents.
S
trainers should be cleaned after initial startup
.
7. Pipe sealing compound should be applied sparingly after cleaning and
m
a

i
nnermost inside the valve. Sealing compound is to be placed on male
