information and procedures to prepare the unit and installation
site as well as to install the unit.
ELECTRIC SHOCK HAZARD:
• Plug unit into a properly grounded electrical receptacle
of space between all sides of the condensing unit and any
combustible surfaces.
This unit must be installed by qualified, trained installers.
Installation must conform to all local electrical and
plumbing codes. Check with local plumbing and electrical
inspectors for proper procedures and codes.
Locate unit at the proper counter height in an area that is
convenient for use. Location should be level and strong
enough to support weight of unit and contents.
Transport and install unit in upright position only. Failure
to do so may result in damage to the refrigeration system.
When shipped during cold weather months, store unit in
proper ambient temperature environment for 10 hours to
prevent compressor and/or refrigerant line damage. If unit
is turned on and there is excessive noise and vibration,
turn off immediately and allow additional warm up time.
This unit is designed for use in environments where the
ambient temperature is between 65°F (18°C) and 86°F
(30°C).
Provide louvered or grill-style openings with a minimum
size of 12″ x 12″/144 square inches (31 x 31 cm/
961 square cm) in the cabinetry in front of and behind the
condensing unit for proper ventilation. Failure to provide
adequate air flow through the condensing unit may cause
unit failure and will void the unit warranty.
Do not locate unit in an area subject to excessive
temperatures or grease from grills, fryers, etc. Excessive
temperatures could cause damage to the unit.

IMPORTANT OWNER INFORMATION section for
details.
Preparing the Unit for Installation
The orientation of the condensing unit on all FTB models can
be adjusted to match the layout of the installation site. It can
be rotated 90° or 180° from its factory-installed position. On
FTB-3, FTB-S2, and FTB-S3 models, the condensing unit
can be installed in several positions along the bottom of the
frost top enclosure using pre-drilled holes at 6-1/2″ (165 mm)
increments. The condensing unit on FTB-2 models can be
installed in pre-drilled holes at 3″ (76 mm) increments.
Survey the installation site and determine if adjustment to
the orientation and/or position of the condensing unit is
necessary. Take into account the need for louvered or grill-style
openings in the cabinetry to provide proper ventilation for the
condensing unit as well as access to the control panel. One of
these ventilation openings must be in front of the condensing
coils with the other on the opposite side. If adjustment to the
orientation and/or position of the condensing unit is necessary,
use the following procedure(s).
Rotating the Condensing Unit
This procedure can be performed on all FTB models.
1. Place blocks underneath the condensing unit for support
during rotation.
2. Remove the 4 mounting screws that secure the condensing
unit support frame to the underside of the frost top enclosure.
3. Rotate the condensing unit 90° or 180°, depending on the
installation site.
NOTE: Do not rotate the condensing unit in a direction that will
put the evaporator lines or any other obstruction in front
of the condenser coil.
4. Reattach the condensing unit support frame to the underside
of the frost top enclosure using the 4 mounting screws.

Moving the Condensing Unit
This procedure can be performed on FTB-2, FTB-3, FTB-S2,
and FTB-S3 models only.
1. Remove the four mounting screws that secure the
condensing unit support frame to the underside of the frost
top enclosure.
2. Move the condensing unit to the desired position. The
condensing unit can be installed in several positions along
the bottom of the frost top enclosure using pre-drilled holes
at 6-1/2″ (165 mm) increments (3″ [76 mm] increments for
FTB-2).
3. Reattach the condensing unit support frame to the frost
top enclosure using the four mounting screws.
Installing the Unit
NOTICE
Use caution and avoid hitting condensing unit hoses/lines
when installing unit. Damage caused during installation is
not covered under warranty.
1. Lift the unit out of the shipping frame and carefully lower it
into the countertop cutout. This step requires two or more
people, depending on the unit.
2. Apply National Sanitation Foundation-approved (NSFapproved) silicone sealant around the edge of the unit to
seal it to the countertop.
3. Install the control panel in the desired location.
• The control panel can be installed on one of three sides
of the condensing unit support frame. Do not install the
control panel in front of the condenser coils.
• The control panel can be installed remotely within 48”
(1219 mm) of the condensing unit. Refer to the “Installing
the Control Panel Remotely” procedure in this section.
4. Connect the 1″ NPT drain fitting to a trap and drain line
(except FTB-3/4 and -1 models). If a trap and drain line
are not available, a catch pan (not supplied) must be used
under the drain fitting to contain water draining from the
frost top enclosure.
NOTE: Consult a qualified plumber for proper trap and drain
installation that conforms to local plumbing codes.
Moving a Condensing Unit
Preparing the Installation Site
1. Cut the appropriate opening in the countertop for the unit
being installed. Refer to “Countertop Cutout Dimensions”
in this section.
2. If installing the control panel remotely, cut and drill the
appropriate holes in the vertical surface where the control
panel will be installed. Refer to the “Installing the Control
Panel Remotely” procedure for cutout dimensions.
3. Make structural modifications or add bracing underneath
the countertop to ensure the countertop will support the
weight of the unit and its contents. Make sure a minimum
2″ (51 mm) clearance will be available between the
condensing unit and any interior surface.
NOTE: The countertop must be level to ensure proper draining
of the frost top enclosure.
4. Cut the required openings in the cabinetry to provide
proper ventilation to the condensing unit as well as
access to the control panel. Two openings, each with a
minimum size of 12″ x 12″/144 square inches (31 x 31 cm/
961 square cm), are required. For proper operation,
one of these ventilation openings must be in front of
the condenser coils with the other on the opposite side.
Louvered or grill-style panels should be installed in the
openings to protect the condensing unit.
5. Make sure a grounded electrical receptacle of the correct
voltage, size, and plug configuration is within 6′ (1829
mm) of the mounting location for the control panel. See
the SPECIFICATIONS section for details.
Installing a FTB-2
5. Clean the frost top enclosure thoroughly in preparation for
initial operation. Refer to the MAINTENANCE section for
proper cleaning procedures.
NOTE: If a catch pan is used underneath the drain fitting,
make sure the pan is emptied regularly to prevent overflowing.
6. Plug the unit into a properly grounded electrical receptacle
of the correct voltage, size, and plug configuration. See the
SPECIFICATIONS section for details.

Installing the Control Panel Remotely
Use the following procedure to install the control panel
remotely.
Control panel must be mounted in a vertical surface.
Mounting control panel in a horizontal surface may result
in the collection of liquids and lead to electric shock.
1. Cut and drill the appropriate holes in the mounting surface.
Refer to the “Control Panel Cutout and Screw Hole
Dimensions” chart for the cutout dimensions.
2. Remove the four trim cover screws from the control panel
and remove the trim cover.
3. Position the control panel into the cutout opening through
the backside.
4. Fasten the control panel to the vertical surface using four
screws (not supplied).
5. Apply a 1/4″ (6 mm) bead of NSF-approved silicone sealant
where the trim cover will contact the cabinet surface. Refer
to the “Control Panel Cutout and Screw Hole Dimensions”
illustration for more information.
6. Reinstall the trim cover on the control panel and secure
in position using the four trim cover screws. Make sure to
embed the trim cover edge into the silicone.
