2.2.3. NOVA Detergent and Rinse Dispenser (Optional)
The NOVA Detergent and Rinse Dispenser has its own reference manual.
Familiarize yourself with the dispenser’s reference manual before proceeding with
1. The NOVA dispenser is pre-wired with a multi-conductor electrical cable that is to
be run through a conduit to the power block inside the control panel drawer. Use
a ½” watertight conduit meeting all local and national codes. A conduit fitting is
present on the bottom of the dispenser where the power cable exits. A mounting
plate to receive the ½” conduit is provided on the top right-hand corner (facing
the back) of the machine.
i. Run an appropriate length of ½” conduit from your dispenser to the mounting
plate where it will be secured. The conduit needs to be of sufficient length
and flexibility to permit the machine to be moved for cleaning without having
to disconnect any wiring.
ii. Run your dispenser wires through the conduit and through the enclosed area
across the top of the machine and then feed them through the access hole
provided in the back of the control panel drawer.
iii. With the machine’s power “OFF”, connect your detergent and rinse dispenser
wires to the power block supplied and labeled (“DISPENSER 110V - 3 AMPS
MAX”) inside the control panel drawer. The table that follows lists the
function of each conductor of the multi-conductor electrical cable.
