Section 2 Installation
Prepare And Plan Your Installation
1. Read through these instructions completely. Determine
what is applicable to the installation.
Inspect The Equipment Packaging
2. Visually inspect the exterior of the package and skid or
container. Any damage should be noted and reported
to the delivering carrier immediately. Take multiple
pictures of the damage.
3. If damaged, open and inspect the contents with the
carrier.
• Retain all crating material until an inspection has
been made or waived.
Uncrating the Equipment
,
Caution
Never attempt to lift or move these units by yourself. The
use of a mechanical lift is required.
4. First cut and remove the banding from around the
crate.
5. Remove the front of the crate material, use of some
tools will be required.
6. Remove the top of the crate as well and lift the unit off
the skid.
7. Bolts, screws and other accessories needed for
fastening units together are in a bag located inside one
of the units. The unit is marked with a note attached to
the front. Be sure all items are included.
8. Care must be taken so the equipment is not damaged
during unloading and movement into the building.
Inspect The Equipment
9. Check the lower portion of the unit to be sure legs or
casters are not bent.
10. Also open the compressor compartment housing and
visually inspect the refrigeration package. Be sure lines
are secure and base is still intact.
11. In the event that the exterior is not damaged, yet upon
opening, there is concealed damage to the equipment
notify the carrier. Notification should be made verbally
as well as in written form. Take multiple pictures of the
damage.
• Request an inspection by the shipping company
of the damaged equipment. This should be done
within 10 days from receipt of the equipment.
• Freight carriers can supply the necessary damage
forms upon request.
• Retain all crating material until an inspection has
been made or waived.
Utilities
DANGER
Be sure all electrical power to this equipment or units
already in place have been disconnected before starting
to assemble the line-up.
12. Check utility rough-in dimensions and locations against
the presentation drawing to insure accuracy.
13. Verify that access to utilities will be available after
lineup installation.
14. Check wall to wall dimensions to make sure there are
proper clearances.
15. For any counter requiring a water hookup the water
pressure must be 20-80psi (138-552kPa).

Installation Section 2
16. Plumbers, electricians and refrigeration installers
should work at the same time as the equipment
installers if possible. This will allow them proper access
to their work before it is obstructed by the equipment.
17. Plumbing, electrical and ventilation provisions must
be made in floors, walls or ceilings. Utilities should be
roughed-in and surfaces finished.
Preparation For All Lines
18. All Delfield Custom Systems line-ups have been
assembled at the factory before shipment. Each unit
is marked with the work order number, SKU (item)
number and serial number. The SKU number is identical
to that marked on the sales presentation drawing. Use
these numbers as a guide during installation.
19. Starting points for an installation vary, depending on
the building layout and the type of equipment included
in the line-up.
• A good place to start assembling the line-up is
where the equipment will tie-in to an end wall or to
other equipment.
• If your line-up contains an equipment stand and
cooking equipment that requires a ventilation duct,
that would be a good place to begin.
20. Check your drawings for the correct work height.
Standard work height is 36” (91.4cm) but depending
on the installation it may be lower or higher. The work
height is the distance from the finished floor to the
stainless steel top.
Preparation For Curb-Mount Only
21. All electrical, water, drain and refrigeration lines must
be pre-plumbed.
22. It is essential that the curb is perfectly level. If the curb
has imperfections, it may be necessary to use metal
shims to achieve level units.
Refrigeration Quick Connects
23. If necessary, determine at what stage of the installation
refrigeration lines, drains and thermostat probes will be
accessible and easily connected.
24. Remove the caps from the quick connect lines and
screw them together. Tighten using two wrenches. Use
soap bubbles to look for any leaks.
25. Run the drain line to the drain pan mounted under the
compressor. Make sure to route the line so it is not
kinked or running upwards.
26. There is a T-stat probe that needs to be hooked to the
t-stat in the compressor housing. The t-stat probe ends
are keyed so they will only go into one slot. The unit
will not run correctly if the probe ends are in the wrong
slots.

27. Units that are 72” (178cm) or longer will have six legs.
On these units, adjust the two center legs’ feet up until
they no longer touch the floor.
28. The first unit must be leveled at its work height. Level
the unit by adjusting the bullet feet on the four outside
legs. Set the level on the unit length wise first, and level
the unit end to end. Next, place the level front to back
and level the unit again. A longer level will be more
accurate.
29. Clean the spline bars of all dust, oils, packing materials,
residue or other foreign matter, in order to ensure a
good seal between the units.
30. If applicable adjust the center legs’ feet until they rest
firmly on the floor.
31. Leg location can also be adjusted. Move them to the
left or right if your layout requires.
32. Place the next unit into position and level at its work
height as previously described.
33. Each unit has a heavy duty spline bar on each end of
the top. Match the front nosing and the backsplash.
Cafeteria lines replace the backsplash with a second
nosing.
34. Clamp the units together tightly. Do not rely on the
fasteners to pull the units together.
35. Custom System line-ups have been pre-assembled at
the factory to ensure proper fit. As the line-up was dis-
assembled for shipping, a yellow sticker was placed on
each unit indicating the location and direction in which
fasteners are to be re-installed.
36. Insert the screws into the matching holes in the
adjacent unit with #14 x 3/4” lag type hex head sheet
metal screws.
37. A bead of NSF listed silicone can be added for a closed,
tight seam.

Attach Non-Refrigerated Bases (Shelving Units)
38. The alignment of shelving units, whether open shelf,
hinged or sliding door or drawer base, is achieved with
screws. 1” (2.5cm) diameter holes are located at the
top of the interior sides to allow the unit to be fastened
to the adjacent unit with #14 x 3/4” lag type hex head
sheet metal screws. A yellow sticker will indicate where
the units are to be fastened together.
Attach Refrigerated Bases
,
Caution
If a refrigerated base does not have a condensate
evaporator supplied, you must connect the condensate
line to a suitable drain. Otherwise, water will collect on
the floor, causing a potentially hazardous situation.
39. Refrigerated bases use screws. The location for
fastening two units together is in the machine
compartment (behind the louver panel) on self-
contained units. Use #14 x 1.25” hex head screws.
40. Two refrigerated units must be splined behind the units
at the backsplash, using #8 x 0.75” pan Phillips head
screw with 1/4-20 locking nut. In the front, a small
stainless steel strap is used under the front nosing to
join the units, fastened with Phillips truss head sheet
metal screws.
