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” 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 MK81A.SS 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; then securely fasten with 3/8-16 UNC Hex Nuts and 3/8" washers (Not supplied).
Seal and tighten tee (1-1/4) to floor flange making certain the tee is facing the proper
location.
STEP 5: Assemble nipple (1-1/4” x 21-1/2”) to the tee (1-1/4”) and tighten with a pipe wrench.
STEP 6: Assemble the eyewash assembly to the waste bend, then assemble the 1-1/4” tee to the
cross. Attach this assembly to nipple (1-1/4” x 21-1/2").
STEP 7: Assemble in the following order:
Attach nipple (1-1/4” x 52-1/2”) onto the cross.
Attach tee (1-1/4” x 1-1/4”x1”) onto nipple.
Attach plug (1-1/4”) to unused portion of tee.
Attach nipple (1 x 24”) onto tee.
Attach elbow 1” straight onto nipple.
Attach nipple (1-1/4” x 6”) onto cross side (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.SS Valve, then connect both nipples
(1/4” x 9”) with the (1/4”) union.
Attach nipple (1/4” x 9”) onto the eyewash assembly.
Attach union (1/4”) onto nipple (1/4” x 9).
Attach nipple (1/4” x 9”) onto the outlet of MK81A.SS 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.
