oPeration
The Mug Froster/Plate Chiller is designed to chill mugs, glasses, plates, etc. that will appear “frosted” when removed.
The Mug Froster/Plate Chiller should be filled with dry, room-temperature mugs, glasses, plates, etc. to allow maximum
chilling. During business hours, the Mug Froster/Plate Chiller can be loaded with additional dry, room-temperature mugs,
glasses, plates, etc. Allow 30 minutes for chilling.

digital Controller oPeration
Automatic Defrost
Each time the door is opened, moisture from the outside air enters the cabinet. Consequently, frost builds up on the evaporator coil
over time. To eliminate this buildup and keep the unit running efciently, Glastender frosters are programmed to automatically
defrost 3 times each day.
Manually-activated, 6-hour defrost
Over time, which varies depending on the level of humidity in the air and the number of door openings, a manually-activated, 6-hour
defrost cycle will be required to completely free the evaporator drain pan of frost buildup. Activate this defrost cycle by pressing the
round button next to the digital controller. The controller display will alternate between ECO and ON. An in-progress, 6-hour defrost
cycle can be canceled at any time by pressing the round button.
Activate the 6-hour defrost cycle at the close of business, at least once per week. The froster will automatically resume normal
operation six hours later.
Digital Controller Trouble Shooting Error Codes
If the digital controller display shows an Err 1 or Err 3 error code, this is likely the result of disconnected digital controller wires.
These wires are commonly disconnected for service and maintenance. Please verify controller wires are connected before calling for
service, because service calls to reconnect the controller are not covered by the factory warranty.

Cleaning instruCtions
Cleaning is essential to sustaining the integrity of your equipment and preventing corrosion.
ESTIMATED CLEANING TIME: 5 to 10 minutes per unit daily, 30 minutes quarterly
FREQUENCY: Daily cleaning of exterior & door gaskets. Quarterly cleaning of interior, including shelves.
PROCEDURE:
1. A non-chlorine based cleaner or mild detergent and warm water applied with a soft cloth or sponge to all contact
surfaces.
2. Immediately rinse off cleaning agent(s), using clean warm water, clean soft cloth or sponge.
3. Dry with a soft clean cloth, removing standing water as soon as possible.
NOTES:
1. Never use hydrochloric acid, wire brushes, steel wool, scrapers, or chlorine based cleaners on stainless steel surfaces,
since they will break down the passivity layer and allow corrosion to occur.
2. On stainless steel surfaces, you may use a soft bristle brush or Scotch-Brite®pad for more stubborn stains. Always
scrub with the direction of the grain. Follow with a thorough cleaning as described above.
3. Deposits from food preparation must be properly removed. Even hard water deposits will rust stainless steel, if not
removed.
4. Repeated cleaning may dry up black-vinyl-clad steel (exterior) surfaces of the cooler. Armor All®or similar product
can bring back the shine. Apply the product to a cloth and then rub into the surface, rather than spraying it directly onto
the black-vinyl-clad surface.
5. The cooler door gaskets are most often overlooked when cleaning. Failure to clean them regularly will lead to premature
failure, since alcohol and moisture build-up breaks down the gasket material.
6. Mug frosters have a manual defrost timer switch on the front near the bottom, which will activate a 6-hour defrost cycle.
Depressing the switch before you close for the evening will remove excess frost build-up on the interior liner. This
procedure should be done as often as is necessary. It should also be done the night before the quarterly interior cleaning.

requested during other than normal working hours, the end user will be
charged the premium portion of the overtime rate.
The warranty covers substantiated travel expenses for up to 2 hours /
100 miles round trip up to a maximum of $150. Any additional costs

ing an installation error, or service calls that reveal the unit is function-
ing normally will not be reimbursed under warranty.

cleaned regularly. Failure to provide adequate air flow to a refrigeration
unit will void the warranty.

any other indirect, incidental, special, or consequential damage includ-
ing, but not limited to, product spoilage or loss.
