English
5. Carefully lower the condensing unit followed by the cold
shelf into the countertop cutout. This step requires two or
more people.
• The condensing unit must go into the cutout first and be
fastened to a level, stable surface within 4' (1219 mm) of
the connections on the bottom of the cold shelf. Refer to
the SPECIFICATIONS section for installation dimensions.
• The cold shelf rests on top of the four leveling bolts,
which are part of the mounting bracket assembly
installed at each corner of the countertop cutout.
6. Adjust the leveling bolts underneath each corner of the unit so
that the shelf is flush or slightly below the countertop surface.
7. Tighten the lock nut on each leveling bolt to secure the
position.
8. Apply a bead of NSF-approved silicone sealant in the gap
above the countertop and the cold shelf. To apply a clean,
consistent sealant bead:
a. Make sure the shelf is centered in the countertop cutout.
b. Install masking tape on each side of the gap to define
the edge of the sealant.
c. Carefully apply sealant into the gap.
d. Quickly smooth the sealant surface.
e. Carefully remove the masking tape before the sealant dries.
NOTE: The silicone sealant must be rated for use at temperatures
between -10°F (-23°C) and 250°F (121°C).
9. Apply polyurethane-based foam sealant in the gap
underneath the countertop and the cold shelf.
Seal this gap with foam sealant
underneath the entire unit.
Foam Sealant Gap
CAUTION
DO NOT tip unit/mounting surface after final installation.
Unit is free-floating and could fall out if tipped—for
permanent, horizontal installations only.
10. Install the control panel in the desired location, if installing
remotely.
• The control panel can be installed remotely within
4' (1219 mm) of the condensing unit. Refer to the
"Installing the Control Enclosure Remotely" procedure
in this section.
11. Clean the cold shelf surface thoroughly in preparation for
initial operation. Refer to the MAINTENANCE section for
proper cleaning procedures.
12. Plug the unit into a properly grounded electrical receptacle
of the correct voltage, size, and plug configuration. See the
SPECIFICATIONS section for details.

Installing an Under Mounted Unit
(CSU Models)
CSU Series units are surface mounted directly against the
underside of a solid surface countertop (no cutout is required).
Cooling transfers through the countertop to the top side for a
true, seamless installation.
1. Remove the mounting
bracket assembly from
each corner of the cold
shelf. To remove:
a. Remove the two shipping
screws and washers that
attach each mounting
bracket assembly to the
bottom of the unit.
b. Carefully lift the cold
shelf above the wooden shipping frame, and rotate it far
enough to allow the unit to be set back down on top of
the frame (the mounting brackets will stay on the frame
or fall out the bottom). Make sure the flexible tubes from
the condensing unit are not strained or damaged. This
step requires two or more people, depending on the unit.
c. Remove the mounting bracket assemblies from the
frame, if necessary.
2. On each mounting bracket
assembly, remove
shipping screws and the
triangular shipping bracket
that was used to attach the
mounting bracket assembly
to the bottom of the cold
shelf, and discard.
3. Attach three of the mounting
bracket assemblies to the
underside of the prepared
countertop at the pre-drilled locations. To attach each:
NOTE: See installation illustration on the following page.
a. Align the u-shaped mounting holes on the mounting
bracket with the two pre-drilled mounting holes on the
underside of the countertop. The inside surface of the
mounting bracket should be facing the unit.
b. Insert appropriate fasteners through the mounting
bracket and into appropriate anchoring devices in the
mounting holes on the underside of the countertop.
Tighten securely.
4. Apply a layer of thermal mastic to the top of the shelf using
a 3/16" (5 mm) notched trowel.
5. Carefully lift the cold shelf up and into the three mounting
brackets on the underside of the countertop. This step
requires two or more people.
• The cold shelf rests on top of the leveling bolts, which
are part of the mounting bracket assembly installed at
each corner of the cold shelf.
• Slide one end of the cold shelf into the two brackets on
one end while rotating it into the single bracket on the
opposite end.
• The condensing unit must be fastened to a level, stable
surface within 4' (1219 mm) of the connections on the
bottom of the cold shelf. Refer to the SPECIFICATIONS
section for installation dimensions.
