Exposed surfaces can be hot
to the touch and may cause
burns.

CAUTION:

SHOCK HAZARD

DO NOT splash or pour water
onto control panel or wiring.

Always use an inset.
DO NOT place food directly
into the warmer.

Always pour hot water into the
warmer before it is preheated.
DO NOT pour water into a
dry, heated warmer. This may
damage the unit.

DO NOT put ice into a
warmer pan. This will cause
condensation on the inside of
the warmer. Damage caused
by condensation is NOT
covered by warranty.

Stir thick food items frequently
to keep food heated uniformly.

WET OR DRY OPERATION for WARMERS

1. Carefully read the description of the warmer operation on the

specication sheet.

2. a. Most warmers are designed for WET OR DRY operation.

b. Warmers may be used wet, or may be used dry. However

warmers may NOT be used wet-to-dry or dry-to-wet unless they
have been allowed to cool to room temperature between the
change in wet or dry operation.

c. Wells Manufacturing recommends operating WET for consistent

food heating.

d. If your wet-operation warmer is allowed to run dry, turn it OFF and

allow to cool to room temperature before adding water.

3. If the warmer is to be used for WET operation, add approximately
1” of hot tap water before turning the warmer ON. Use of hot water
will allow a faster preheat.

a. Check the water level frequently and add hot water as necessary

to prevent the warmer from running dry. Do not add water to the
warmer if it has run dry.

b. If your wet-operation warmer is allowed to run dry, turn it

OFF and allow to cool to room temperature before adding water.

warmer.

a. Insets are available as accessories in 2½ qt., 4qt., 7 qt., and 11 qt.

sizes with lids and adapter tops.

b. For dry operation, a 6” deep pan or inset is recommended.

the control for the desired temperature. Be sure to keep the warmer

covered during preheat and operation.

Keep insets covered to
maintain food quality and
temperature.
