INSTALLATION INSTRUCTION FOR SEF-TW ON SEF-18XY
The unit is designed so the eyewash has a dedicated supply line. This allows the eyewash to have a tepid
water supply, set with a Thermostatic Mixing Valve (-TW). Weight is 11.2 lbs and flow rate is 2.5 gpm at
minimum of 35psi.
For this type of installation, follow the installation instructions below:
INSTALLATION:
a. Attach the (2) ELBOWs, (2) TEEs, and (8) brass pipe nipples to the hot and cold inlet of the thermostatic
mixing valve with checks. Use Teflon tape on all threaded connections.
b. See the installation and maintenance manual provided for the SE-370 Emergency Eye Wash Valve for the
required installation recommendations. The valve should be mounted less than 18” from the sink surface.
This allows enough clearance for the supply hoses to reach the inlets. Verify the supply hoses reach the
connections before mounting the valve.
c. Mount the thermostatic mixing valve to the wall and fasten the valve to the wall using 1/2” pipe hangers
with wall plates (not supplied).
d. Connect the (2) supply (hot-cold) hoses (3/8”compression x ½”NPS) to the mixing valve TEE and using
wrench tighten. Connect the other end of the hoses (with fiber washer) to the water supplies, making sure
the hot is to hot & the cold is too cold and wrench tighten.
e. Connect the other branches of the 2 TEEs to the rest of the faucet with (2) hoses (3/8”compress x ½”NPS)
f. Connect the center outlet of the tepid water supply valve directly to the eyewash inlet (don’t use any TEE
there) but use the hose (½”-14 NPT x ½”-14 NPSM).
NOTE: REFER TO THE SEPARATE IOM SHEET LOCATED IN THE VALVE BOX FOR ADJUSTMENT, TESTING
AND MAINTENANCE.
ANSI Z358.1 requires that the delivered flushing fluid temperature shall be tepid. Also, in circumstances where
chemical reaction is accelerated by flushing fluid temperature, a medical advisor should be consulted for the
optimum temperature of each application. Refer to the IOM sheet located in the thermostatic mixing valve
box for adjustment, testing and maintenance instructions to adjust the valve to the proper temperature.
