LOCATION

The refrigerated merchandisers have been designed for
use only in air conditioned stores where temperatur e and
humidity are maintained at or below 75°F and 55% rela­tive humidity . DO NO T allow air conditioning, electric fans,
ovens, open doors or windows (etc .) to create air cur­rents around the merchandiser, as this will impair its cor­rect operation.
Product temperature should always be maintained at a
constant and proper temperature. This means that from
the time the product is received, through storage, prepa­ration and display, the temperature of the product must
be controlled to maximize life of the pr oduct.

UNCRA TING THE ST AND

Place the fixture as close to its permanent position as
possible. Remove the top of the crate. Detach the walls
from each other and remove from the skid. Unbolt the
case from the skid. The fixture can now be lifted off the
crate skid. Lift only at base of stand!

EXTERIOR LOADING

These models have not been structurally designed to sup-
port excessive external loading. Do not walk on their
tops; This could cause serious personal injury and dam­age to the fixture.

SETTING AND JOINING

The sectional construction of these models enable them
to be joined in line to give the effect of one continuous
display. A joint trim kit is supplied with each joint.

LEVELING AND PLACEMENT

IMPOR TANT! It is imperative that cases be lev­eled from front to back and side to side prior to
joining.

NOTE: A. To avoid removing concrete flooring, begin lineup

leveling from the highest point of the store floor.
B. When wedges are involved in a lineup, set them first.

All cases were leveled and joined prior to shipment to
insure the closest possible fit when cases are joined in the
field. When joining, use a carpenters level and shim legs
accordingly. Case must be raised correctly, under legs
where support is best, to prevent damage to case.

1. Check level of floor where cases ar e to be set.
Determine the highest point of the floor; cases will
be set off this point.

2. Set first case, and adjust legs over the highest part of
the floor so that case is level. Prevent damage – case
must be raised under leg or by use of 2x6 or 2x4 leg
brace. Remove side and back leg braces after case is
set.

3. Set second case as close as possible to the first case,
and level case to the first using the instructions in

IGSS-ESS/ESSS-0303

step one.

JOINING - ESSS

1. Apply masking tape 1/8" in from end of case on
inside and outside rear mullion on both cases to be
joined.

2. Apply liberal bead of case joint sealant (butyl) to
dotted area shown in (Fig.2, #1) of first case. Apply
heavy amount to cov er entire shaded area.

DO NO T USE PERMAGUM!

It is the contractor’s responsibility to install

case(s) according to local construction and

health codes.

3. Slide second case up to first case snugly . Then lev el
second case to the first case so glass front, bumper
and top are flush.

4. To compress silicone at joint, use two Jurgenson
wood clamps. Mak e sure case is lev el from front to
back and side to side on inside bulkheads at joint.

5. Attach sections together via a 2 bolts located in the
base of the case. Secure the ov erhead structure by
bolting the bracket, located inside behind lights.

6. Apply bead of silicone to top of bulkheads.

7. Slip on stainless steel bulkhead cap. Also apply
silicone to seam between overhead light tubes.

8. Recheck all camlocks.

JOINING - ESS

1. Using a 7mm Allen Wrench, lock in and close the
three camlock.

4

Rev.0303

Installation (cont.)

Do not use cam locks to pull cases together.

2. Secure joint backer. Located behind cart bumper
suport at joints. T o adjust scr ews holding bumper
cart to case on either side or the joint and slide
extrusion to center of joint. This piece supports the
fornt panel at the joint.

3. Apply bead of silicone to top of bulkheads.

4. Slip on stainless steel bulkhead cap. Also apply
silicone to seam between overhead light tubes.

5. Recheck all camlocks.

CORNER WEDGES

If a wedge is used in the middle of the lineup, the wedge
must be set off the highese point on the floor FIRST, with
the rest of the lineup being leveled from that point.
If an outside corner display is used, it must be mounted
and set before attaching any joint trim parts. Set the front
stainless steel bumper so it aligns with bumpers on the
two cases.

ESSS

Anchor woth bolts through brack et hjoles on legs of cases.
Install rear stianless steel plate with shelf standards to back
edge of ends with screws. Install brackest and shelves.
Next, connect applicable electrical, refrigeration, water , and
drain lines throug the access panels in the side of the stand.
After the cases have been leveled and joined, and refrig­eration, electrical, and waste paping work completed, in­stall the splashguards. (See instructions in the “Finishing

Touches” section of this booklet). Fasten along the top
edge, or center, with #10 x 3/4” sheet metal screws in the
pre-drilled holes.

ESS
REFRIGERATED

Inside Wedge: Line up taper pins with holes on adjoining
case. Turn camlock to lock in. Two camlocks are located at
the rear of the case behind the air discharge and behind
the lower electrical raceway panel. Bolt the front of the
wedge into the adjoining case. In refrigerated cases, the
bolt is located under the pans in the front. In the hot case,
the cases are bolted together by means of a bracket lo­cated behind the front panel. Remove the front panel by
lifting up and then sliding out.
Outside wedge: Taper pin and camlock locations are the
same as a standard case.

DRY

Inside Wedge: Bolt the w edge into the sides of the adjoin­ing case. Use bolts provided.
Inside Pedestal Wedge: Set wedge on the adjoining case’s
mounting brackets located at the base of the unit, and
bolt down. Drive screws provided through the sides of
the wedge (4 screws per side), accessible through the back
of the wedge.

COMMON END BETWEEN UNLIKE CASES AND HOT
CASES

Bolt end onto case using bolts provided in pr e-drilled holes
behind front panel through brakcet provided and in the
rear behind the rear access panel on the bottom. Hot
cases are onlu bolted in two places. Common ends be­tween refrigerated cases are bolted together the air dis­charge panel. Remove air discharge panel by lifting up and
out.
Nex connect applicable electrical, r efrigeration, water , and
drain lines.

JOINT TRIM

After cases have been leveled and joined, and refrigera­tion, electrical, and wasted piping work completed, install
the splashguards. Fasten along the top edge, or center, with
#10 X 3/3" sheet metal screws.

Plumbing

WASTE OUTLET AND P-TRAP

The waste outlet is located off the center of the case on
one side allowing drip piping to be run lengthwise under
the fixture.
A 1-1/2" P-trap and threaded adapter are supplied with
each fixture. The P-trap must be installed to prevent air
leakage and insect entrance into the fixture.

NOTE: PVC-DWV solvent cement is recommended.

Follow the manufacturer’s instructions.

INSTALLING CONDENSATE DRAIN

Poorly or improperly installed condensate drains can se­riously interfere with the operation of this refrigerator,
and result in costly maintenance and pr oduct losses. Please
follow the recommendations listed below when installing
condensate drains to insure a proper installation:

1. Never use pipe for condensate drains smaller than
the nominal diameter of the pipe or P-trap supplied
with the case.

2. When connecting condensate drains, the P-trap
must be used as part of the condensate drain to
prevent air leakage or insect entrance. Store plumb­ing system floor drains should be at least 14" off the
center of the case to allow use of the P-trap pipe

IGSS-ESS/ESSS-0303

section. Nev er use two water seals in series in any
one line. Double P-traps in series will cause a lock
and prevent draining.

3. Always pr ovide as much down hill slope (“fall”) as
possible; 1/8" per foot is the pr eferred minimum.
PVC pipe, when used, must be supported to main­tain the 1/8" pitch and to prevent warping.

4. Avoid long runs of condensate drains. Long runs
make it impossible to pro vide the “fall” necessary for
good drainage.

5. Provide a suitable air break betw een the flood rim of
the floor drain and outlet of condensate drain. 1" is
ideal.

6. Prevent condensate drains fr om freezing:

a. Do not install condensate drains in contact with

non-insulated suction lines. Suction lines should be
insulated with a nonabsorbent insulation material
such as Armstrong’s Armaflex.

b. Where condensate drains are located in dead air

spaces (between refrigerators or betw een a
refrigerator and a wall), provide means to pr event
freezing. The water seal should be insulated to
prevent condensation.

Refrigeration

REFRIGERANT TYPE

The standard refrigerant will be R-22 unless otherwise
specified on the customer order. Check the serial plate
on the case for information.

PIPING

The refrigerant line outlets are located under the case.
Locate first the electrical box, the outlets are then on the
same side of the case but at the opposite end. Insulate
suction lines to prevent condensation drippage.

REFRIGERATION LINES

LIQUID SUCTION
3/8" O.D. 5/8" O.D.

NOTE: The standard coil is piped at 5/8" (suction); however,

the store tie-in may vary depending on the number of
coils and the draw the case has. Depending on the case
setup, the connecting point in the store may be

5

/8", 7/8", or 11/8". Refer to the particular case you are

hooking up.

Refrigerant lines should be sized as shown on the refrig­eration legend furnished by the store.
Install P-traps (oil traps) at the base of all suction line ver ­tical risers.
Pressure drop can rob the system of capacity. To keep the
pressure drop to a minimum, keep refrigerant line run as
short as possible, using the minimum number of elbows.
Where elbows are required, use long radius elbows only.

CONTROL SETTINGS

See the “Case Specs” section of this guidebook for the
appropriate settings for y our merchandiser . Maintain these
parameters to achieve near constant product tempera­tures. Pr oduct temperature should be measured first thing
in the morning, after having been refrigerated overnight.
For all multiplexing, defrost should be time terminated.
Loadmaster valves are not recommended. Defrost times
should be as follows: OFF CYCLE - One time daily for
110 minutes. The number of defrosts per da y should never
change. The duration of the defrost cycle ma y be adjusted
to meet conditions present at your location.

ACCESS TO TX VALVES & DRAIN LINES

MECHANICAL - Remove product fr om end of case. Remove
product racks. Remo ve refrigeration and drain access panels
(labeled). TX valve (mechanical only) and drain are located
under each access panel at end of the case.
ELECTRONIC - The Electr onic Expansion valve master and
slave cylinder(s) are located within the electrical access
panel(s).

ELECTRONIC EXPANSION VALVE (OPTIONAL)

A wide variety of electronic expansion valves and case
controllers can be utilized. Please refer to EEV and con­troller manufacturers inf ormation sheet. Sensors for elec-

tronic expansion valves will be installed on the coil inlet,
coil outlet, and in the discharge air. (Some supermarkets
require a 4th sensor in the return air). Case controllers
will be located in the electrical racewa y or under the case

THERMOSTATIC EXPANSION VALVE LOCATION

This device is located on the same side as the refrigera­tion stub. A Sporlan balanced port expansion valve model
is furnished as standard equipment, unless otherwise speci­fied by customer.

EXP ANSION V AL VE ADJUSTMENT

Expansion valves must be adjusted to fully feed the e vapo­rator. Before attempting any adjustments, make sure the
evaporator is either clear or very lightly covered with frost,
and that the fixture is within 10°F of its expected operat­ing temperature.

MEASURING THE OPERATING SUPERHEAT

1. Determine the suction pressure with an accurate
pressure gauge at the e vaporator outlet.

2. From a refrigerant pr essure temperature chart,
determine the saturation temperature at the
observed suction pressure.

3. Measure the temperature of the suction gas at the
thermostatic remote bulb location.

4. Subtract the saturation temperature obtained in step
No. 2 fr om the temperature measured in step No. 3.

3. The difference is superheat.

5. Set the superheat for 5°F - 7°F.

T-STAT LOCATION

T-Stats are located within the electrical raceway. Refer to
