EWF
FIG. 2
• • • • • Shock hazard. Disconnect power source before servicing. Serious injury or death could result.
• • • • • Installation must be performed by qualified personnel and in accordance with all national and local codes
and ordinances.
• • • • • Not for use in hazardous locations.
• • • • • To prevent damage to the device and/or electrical fire, wire insulation must be rated at 167° F (75° C) – over
copper wire only.
• • • • • When installations are complete, check for correct operation of ALL limit and operating controls!
• • • • • Read all instructions carefully and understand them before starting installation and save for future use.
• • • • • Instruct user how to test and operate this feeding device as described in these instructions.
• • • • • Do not use manual reset low water cutoff with automatic water feeders like the EWF or flooding and prop-
erty damage can occur.
• • • • • If using mixed voltages, DO NOT install jumper wire on LWCO.
• • • • • Wire the water feeder and low water cutoff from the same power sources. Failure to do so could result in
flooding and property damage can occur
INSTALLATION
Piping
Plumb the EWF water feeder as shown in Figure 4.
The EWF must be installed with a manual bypass.
To permit ease of removal for servicing or replace-
ment, install unions and isolation valves. Install
the EWF with the flow direction arrow toward the
boiler. Fill the boiler by manually opening the
bypass valves until the water level is at a normal
level for the boiler, (refer to the boiler
manufacturer's literature for proper fill levels).
Check the system for leaks before proceeding.
Once the system is full, close the bypass valve and
verify that both isolation valves are open. This
routes water through the EWF.
TERMINAL BLOCK CONNECTIONS
CLAMPING PLATE TERMINAL
FIG. 3
FIG. 4
(3)
An uninsulated section of a
single conductor should not be
looped around the terminal and
serve as two separate
connections. The wire must be
severed, thereby providing
supervision of the connection
in the event that the wire
becomes dislodged from under
the terminal. Use 18 AWG
(min.), or as required by local
code. Wire insulation rating
must be at least 167°F (75°C).
