Do not disconnect the control box from the modular unit.

i. Remove the knobs and faceplate from the control box. Pass the

control box through the countertop cutout, and then through
the apron cutout. This will require the box to be rotated so the
mounting tabs clear the hole. Next, lower and position the
modular section into countertop cutout.

ii.

Before final seating of modular section to countertop, apply
a bead of silicone sealant to the underside of the grey gasket
material supplied on the mounting flange. From underneath,
insert screwdriver into the slots in the Wellslok frame and twist
clockwise to move the ears outward as required to secure the
flange tightly to countertop.1

iii. Mount the control box to apron cutout using #10 sheet metal [or

wood] screws to the facing side where the holes were drilled.

iv. Run wiring through the conduit knockout to the terminal block,

making connection as shown in the unit’s wiring diagram to the
correct power source.

v. Mount the front panel onto the control box using the provided

hardware and place the knob on. At this point, you should be
able to power on the unit and check for proper operation.

BASIC USE

BASIC USE

HSW, HT, HW, MDW, MOD, and SS series of round or rectangular,
top-mounted, built-in warmers come equipped with the Wellslok
mounting system. After getting the warmer positioned correctly
into the cutout with the appropriate gasket(s) and sealant applied,
as described in the installation instructions for the unit, access the
underside and turn each Wellslok tab outward with a screwdriver
as shown on the right to secure the warmer to the counter. On
countertops thicker than 16 GA steel, Wellslok extension kit[s]
will be needed. These kits can accommodate countertops up to

1.5 inches (38 mm) thick. Wellslok extension kits can only be

used with UL listed warmers approved for installation in wood
countertops. When installing in custom countertops, please
follow the manufacture’s “suggested” recommendations or
guidelines for installation of heated equipment in their counter
material”.

RECTANGULAR EXTENSION KITS

Rectangular extension kits [number 22593] come with hardware
to secure a single well up to 12 inches (305 mm) by 20 inches (508
mm) in size. For multiple-well models, additional kits will be required.
If your unit is a 4- or 5-well model, then you will need 3 kits for
proper installation. On 2- or 3-well models, you will need 2 kits for
proper installation. The clips will need to be attached under the
countertop and be positioned equally around the unit to assure
proper seating. Once all are in place tighten screws until they are
flush against the underside of the counter and the unit is secured
in place. On some materials, you may wish to place something
in between the tip of the screw and the countertop to prevent
marring the countertop material.
