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,

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.
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”.
Round extension kits [number 22592] come with hardware
to secure one well. 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.
