Chemical Injection Supply System - Raytheon SC125VNV Installation & Maintenance

Chemical Injection Supply
System
The machine may be attached to an external
liquid chemical injection supply system. See
the Chemical Injection Supply System table in
this subsection for more information.
WARNING
Wear eye and hand protection when
handling chemicals; always avoid direct
contact with raw chemicals. Read the
manufacturer's directions for accidental
contact before handling chemicals. Ensure
an eye-rinse facility and an emergency
shower are within easy reach. Check at
regular intervals for chemical leaks.

Undiluted chemical dripping can damage the
machine. Therefore, all chemical injection
supply dispenser pumps should be mounted
below the washer's injection point. All
dispenser tubing should also run below the
injection point. Loops do not prevent drips if
these instructions are not followed. Failure to
follow these instructions could damage the
machine and void the warranty.
Five hose barbs just below the vacuum breaker
facilitate connection to an external chemical
injection supply system. A liquid chemical
supply hose entry port is provided just above
the vacuum breaker so that the hoses may be
routed through the valve panel.

A terminal strip next to the input power block
provides supply output signals for the
chemical injection supply system.
Note: Do not attempt to make chemical
injection supply pump electrical connections
to points other than those provided specifically
for that purpose by the factory.
Machines connected to 200VAC provide L1
and L2 fused outputs rated at 3 amps which
may be used to power 208–240VAC
supply pumps.
Machines connected to 400VAC do not
provide L1 and L2 outputs. An external power
source must be provided to power the chemical
SW016 supply pump.
Do not use L1 or L2 with the common line to
deliver 120VAC to chemical injection supply
pumps if the machine is equipped with a
control transformer. The transformer will not
5
be able to provide enough current to operate
5/16 / 8
the control circuits and drive the chemical
supply pumps.
Attempting to obtain 110VAC by using L1 or
L2 with the common may damage laundry
machine circuitry and/or the chemical
injection system. Using a 240VAC power
wire in the washer-extractor and an earth
ground to obtain 110VAC could cause
microprocessor problems.
Consult the chemical injection supply system
instructions for operational details. See Figure
2–9 for terminal strip decal.
