FEATURES & OPERATING CONTROLS

WELLSLOKS

INDICATOR
LIGHT

TEMPERATURE
CONTROL
(INFINITE
SWITCH)

IMPORTANT:

DO NOT LEAVE ON

“PREHEAT”

Unit may cycle on hi-limit
control, leading to premature
failure of the hi-limit control
device.

A. INFINITE SWITCH

1. On INFINITE SWITCH CONTROLLED warmers, power is

applied to the heating element based on the control knob

position, which varies the duty cycle of the heating element.

2. The desired temperature is controlled by rotating the
TEMPERATURE CONTROL KNOB. The knob may have a
numeric scale, where higher numbers correspond to higher

IL2614

temperature. LO is the lowest temperature setting; PREHEAT
is a “continuous on” setting. Innite switch controlled warmers

are equipped with a hi-limit device to prevent overheating. The
hi-limit will self-reset after the warmer has cooled.

3. On warmers equipped with an INDICATOR LIGHT, the light will

glow when the innite switch is in any position other than OFF.

4. The TEMPERATURE CONTROL KNOB will rotate without
stopping, with PREHEAT and OFF having obvious detents.

The OFF position is a “positive” OFF (i.e. the switch is positively

held in the open position).

NOTE: An innite switch controls temperature by varying the ratio of
“on” time to “off” time. Thus, no temperature sensing devise is required.

B. MOUNTING

1. Top-mounted drop-in warmers are equipped with WELLSLOKS,
uniquely designed turnout tabs which help secure the warmer

top ange to the countertop.

2. See the Installation Instructions, supplied with the particular
appliance, for details.

C. DRAINS

1. “D” units (e.g. SS-10D) have drains for each well, with each pan

having an individual drain valve.
