GENERAL MAINTENANCE
29
of 90
The most important facets of proper care and
maintenance of your machine are the electrical
power supplied to it, leveling, and cleanliness of the
machine.
POWER
The machine must be connected to a dedicated 120
VAC, 15 Amp circuit (U.S. and Canada).
CAUTION:
REMOVE POWER TO THE AC DISTRIBUTION
BOX WHEN ANY ELECTRICAL COMPONENTS
ARE CONNECTED / DISCONNECTED FOR
TESTING OR REPLACEMENT.
CLEANING
DO NOT USE A WATER JET OR NOZZLE TO
CLEAN THE VENDER
GLASS DOOR
The display glass should be cleaned inside and
out with paper towels and glass or non-abrasive
all-purpose cleaner. The gasket around the
product door should be wiped down using warm
water, any mild general purpose, non-abrasive
cleaner and a soft towel. Never lubricate the
gasket and always check for cracking or
deformities which may cause leaks. Replace if
necessary.
TRAYS / TRAY INSERTS
The trays and tray inserts should be cleaned
periodically using warm water and a mild
general purpose, non-abrasive cleaner. Care
should be taken to ensure water does not enter
the solenoids. DO NOT USE SOLVENTS OR
ABRASIVE MATERIALS TO CLEAN ANY
PORTION OF THE TRAY.
SLIDE/PUSHER ASSEMBLY
The slide/pusher assembly should be cleaned
periodically using warm water and any mild
general-purpose non-abrasive cleaner. After
drying, the slide assembly needs to have a coat
of Armorall applied. Care should be taken to
ensure liquid does not enter solenoids. DO NOT
USE SOLVENTS OR ABRASIVE MATERIALS
TO CLEAN ANY PORTION OF THE TRAY.
CABINET
Wash the cabinet with a good detergent or soap
mixed in warm water. Wax the vender often with
a good grade of automobile wax. Any corrosion
inside the vender should be removed with fine
steel wool and the area should be painted with
white paint.
Repair any scratches on painted surfaces to
prevent corrosion.
DRAIN PAN
Check the drain pan periodically for dirt, debris,
and proper alignment. Clean as needed.
Ensure nothing obstructs the drain tube and
drain hose.
WARNING
THE COMPRESSOR ELECTRICAL CIRCUIT IS
ALWAYS LIVE WHEN THE PLUG IS CONNECTED
TO AN ELECTRICAL OUTLET.
REFRIGERATION CONDENSER
Clean the condenser periodically of dirt or lint
build-up. Remove the build up with a brush or
vacuum, or blow the dirt out of the condenser
with compressed air and approved safety
nozzle. Ensure nothing obstructs air intake at
the bottom of the main door. Ensure nothing
obstructs air exhaust at the rear of the cabinet.
COIN ACCEPTOR
Follow the Coin Acceptor Manufacturer’s
instructions.
LUBRICATING THE VENDER
The vender refrigeration system does not
require any field lubrication. The hermetic
refrigeration system and fan motors are
manufactured with lifetime lubrication.
EPROM REPLACEMENT
Software changes / upgrades are accomplished by
changing the EPROM on the Control Board.
To change EPROM:
Remove power to the AC Distribution Box.
Remove existing EPROM.
Replace the EPROM. (The EPROM’s legs bend
easily. Remove and replace very carefully.)
Note the alignment notch at one end of the EPROM
and on the control board. The notches must be
matched or problems will occur. Appy power to the
AC distribution box. Display will scroll
