WATER SUPPLY
The minimum recommended supply line is 1/2" IPS COLD. Cold supply temperatures should
range from 35°F to 75°F. Outlet connection is a 1/2" NPT dielectric union. We recommend a
manual bypass loop with appropriate tamper resistant shut-off valves to allow for heater water
system maintenance or service without interrupting emergency eyewash operation.
INSTALLATION PROCEDURE...
PROCEDURE
Use Teflon thread seal tape on all water connections. Do not use pipe dope . This unit
should be mounted as close to the point-of-use as possible.
STEP 1: Mount unit on wall (This unit is intended for indoor use only) per attached
installation drawing. Bolt dia.
3/16” fasteners through heater box. Unit must be installed
in the vertical only, with the inlet and outlet at the bottom. The cold water inlet is on the
right hand side and the hot water outlet is on the left. Under no circumstances can
these be changed. Leave a minimum of
8” clearance above the unit to facilitate
heating element replacement.
STEP 2: Flush supply piping thoroughly prior to connecting to inlet unions. Connect outlet union
to piping leading to eyewash. Check for leaks. Run water through the supply pipe to
remove all debris from the pipe before connecting the heater: Failure to do so could
cause damage to the flow switch. Run water through the supply pipe to remove all
debris from the pipe before connecting the heater. Failure to do so could cause
damage to the flow switch.
The unit should be installed in the plumbing system in such a way that there is no
tendency for the unit to be starved of water. For example: an excessive draw-off of
cold water just before the unit. Also, do not fit an unrestricted hot water draw-off point
below the heater as this will tend to empty the heater by siphoning.
NOTE
ALL MOUNTING AND PLUMBING MUST BE COMPLETE BEFORE
YOU PROCEED WITH ELECTRICAL HOOK-UP. TEST THE
INSTALLATION FOR LEAKS BEFORE CONNECTING THE
ELECTRICAL SUPPLY.
