MAINTENANCE
The following section is a basic guide for general maintenance and servicing of the
vendor. This section is divided into three parts: (I) Preventative Maintenance, (II)
Lubrication Guide, and (III) Care and Cleaning.
I. PREVENTATIVE MAINTENANCE SUGGESTIONS:
Whenever a vendor is visited on its site, the following service should be performed.
Preventative maintenance will help prevent future problems with the vendor.
A. Observe the vendor and its surrounding area for any unusual indications of
problems (rear of cabinet, obstructions of the air flow, dark spots on the sign
face, etc.).
B. Open the door and visually check the inside of the vendor (water accumulation,
rust marks, moisture around the edges of the inner door, etc.).
C. Check the fluorescent lamps, replace as necessary. Replace all lamps within
24 to 48 hours of burnout. This will prevent damage to the ballast.
D. Check the product temperature for proper cooling.
E. Check the evaporator drain for obstruction; water in the evaporator area must
drain to the condensation pan.
F. Empty condensation pan.
G. Clean the condenser filter.
H. Check that evaporator fan runs normally.
I. Check that the compressor and condenser fan run normally.
J. Investigate any unusual sounds (fan blades hitting something, refrigeration
lines rattling, etc.).
K. Clean coin acceptor.
L. Check for proper operation of the coinage mechanism by inserting all
denominations of coins accepted by the vendor.
M. Test the vendor and make a report on the problems.
