LOCATION OF UNIT: The Model 8300FP Freeze Resistant Shower/Eye/Face Wash should be
installed in close proximity to potential accident areas. It should be clearly identified, free from
obstructions and easy to access.
SUPPLY LINE: The minimum recommended line size is 1-1/4” IPS with 30-90 psi (2-6 ATM) flowing
pressure. Where sediment or mineral content is a problem, an inlet filter is recommended.
PLUMBING CONNECTIONS: The main inlet supply connections are 1-1/4” male IPS for shower
and 3/4” female IPS for eyewash. Waste outlet is 1-1/4” female IPS.
MAINTENANCE: In freezing conditions, wipe eye/face wash head and dust cover dry after each use
to prevent unwanted ice buildup.
INSTALLATION PROCEDURE
Refer to Installation Drawing for clarification. Check parts list to insure all required parts are included. Use
pipe joint sealant PST #565 (Loctite) on all connections.
STEP 1: Install the 1-1/4” and 3/4” supply line below the frost line. Provide porous fill with a minimum
size of 5 cubic feet for the supply line drain back.
STEP 2: Install the MK8A and MK81A freeze proof valves in their proper location (See Installation
Drawing). For proper operation, valves must be installed in a vertical position. Valves must not
be bowed or bent as this may result in binding and improper function. Turn the water on and
test for proper operation before burying the valves.
STEP 3: Prepare the emergency shower foundation by using the floor flange as a template. Locate the
three holes for the 3/8-16 UNC x 6" anchor bolts (not supplied). Anchor bolts should extend 1"
above the floor level.
STEP 4: Once the concrete foundation is ready (dry), assemble the floor flange to the anchor bolts; and
then securely fasten with 3/8-16 UNC Hex Nuts and 3/8" washers, (Not supplied). Seal and
tighten tee (1-1/4) tee to floor flange making certain the 1-1/4 tee is facing the proper location.
STEP 5: Assemble (1-1/4” x 21-1/2”) nipple to the (1-1/4”) tee and tighten with a pipe wrench.
STEP 6: Assemble the eye/face wash assembly to the waste bend, then assemble the 1-1/4” tee and
the 1-1/4” x 4” plugged nipple with the plugged side on top, then attach the other 1-1/4” tee to
the 1-1/4” x 4” plugged nipple. Attach this assembly to nipple (1-1/4” x 21-1/2") nipple.
STEP 7: Assemble in the following order:
Attach nipple (1-1/4” x 52-1/2”) onto the eye/face wash assembly.
Attach elbow (1-1/4” x 1”) onto nipple.
Attach nipple (1x 24-5/8”) onto elbow.
Attach street elbow (1”) onto nipple.
Attach nipple (1-1/4” x 6”) onto tee (1-1/4”).
Attach union (1-1/4”) onto nipple (1-1/4” x 6”).
Attach nipple (1-1/4” x 6”) onto the outlet of MK81A Valve, then connect both nipples (1/4” x 9”)
with the (1/4”) union.
Attach nipple (1/4” x 9”) onto the eye/face wash assembly.
Attach union (1/4”) onto nipple (1/4” x 9).
Attach nipple (1/4” x 9”) onto the outlet of MK8A Valve (use the reducer bushing), then connect
both nipples (1/4” x 9”) with the (1/4”) union.
STEP 8: Assemble the sign onto the unit. Use the strap, screws, washers and nuts provided to mount
the sign onto the upright. The sign should be positioned for maximum visibility.
STEP 9: Attach the showerhead. Water test and make the final check up.
