4. Installation

1. Using case blueprints, measure off and mark on the

floor the exact dimensions of where the cases will

sit. Snap chalk line for front and back positions of

base rail or pedestal. Mark the location of each joint

front and back. Find the highest point throughout

the lineup. FLOORS ARE NORMALLY NOT LEVEL!

Determine the highest point of the floor; cases will

be set off this point. All cases in the entire lineup

must be brought up to the highest level of the case

sitting at the highest point in the lineup. This may be

done a few different ways.

a) Walk the floor looking for any mounds or dips.

b) Use a string level.

c) Use a transit.

If a wedge is used in the middle of a lineup, the

wedge must be set on the highest point on the floor

FIRST, with the rest if the lineup being leveled from

it. The Q2-SS case has adjustable legs to allow for

leveling.

2. Set first case over the highest part of the floor and

adjust legs so that case is level. Remove side and

back leg braces after case is set and joined.

3. Set second case within one foot (1') of the first case,

and remove leg skids. Keep the supports along the

length of the case and far end of case. Level case to

the first using the instructions in step one.

4. Apply masking tape 1/8" in from end of case on

inside and outside rear mullion and body work on

both cases to be joined.

5. Apply liberal bead of case joint sealant (butyl) to first

case. Sealant area is shown using a dotted line in

illustration in Step 8. Apply heavy amount to cover

entire shaded area.

DO NOT USE PERMAGUM!

It is the contractor’s responsibility to install

case(s) according to local construction and

health codes.

6. Slide second case up to first case snugly. Then level

second case to the first case so glass front, bumper

and top are flush.

Do not use bolts to pull cases together.

Location

The refrigerated merchandisers have been designed

for use only in air conditioned stores where temperature

and humidity are maintained at or below 75°F and 55%

relative humidity. DO NOT 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.

NOTE: MAINTAIN MIN. CLEARANCE OF 15' FROM

DOORS, VENTS OR HIGH HEAT SOURCES.

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 product.

Uncrating the Stand

Place the fixture as close to its permanent position as

possible. Keep in place, attached case until ready to set/

bolt to adjoining case.

Tighten Glass Screws

Tighten screws along clamshell located on the underside

of glass before placing unit into operation.

Exterior Loading

These models have not been structurally designed to

support 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.

An Alignment pin kit is supplied with every case and

must be used in alignment.

Leveling

IMPORTANT! IT IS IMPERATIVE THAT CASES

BE LEVELED FROM FRONT TO BACK AND SIDE

TO SIDE PRIOR TO JOINING. A LEVEL CASE IS

NECESSARY TO INSURE PROPER OPERATION,

WATER DRAINAGE, GLASS ALIGNMENT AND

OPERATION OF THE HINGES SUPPORTING THE

GLASS. LEVELING THE CASE CORRECTLY WILL

SOLVE MOST HINGE OPERATION PROBLEMS.

Installation (Cont'd)

7. To compress butyl at joint, use two Jurgenson wood

clamps. Make sure case is level from front to back

and side to side on inside bulkheads at joint.

8. Attach sections together via the bolts pictured in the

illustration below.

9. Apply bead of butyl to top of bulk heads and slip on

stainless steel bulkhead cap. Also apply silicone to

seam between joints.

10. Use finger to smooth silicone as thin as possible at

masking tape on inside and outside of rear mullion

(apply additional silicone if necessary). Remove

tape applied on line #4.

11. Remove front, back and end shipping braces.

Installation (Cont'd)

Bumper Installation Instructions

Step 1: Make sure the aluminum

channel and end caps are installed.

Step 3: Starting on one end: while

inserting the bumper, push it up against

the end cap to prevent the bumper from

shrinking after installation (when it gets

cold).

Step 2: Use silicone lubricant to help the

bumper slide into the channel.

Step 4: As you insert the bumper into

the channel with one hand, pull the

bumper toward you with the other

to open the inside lips. Slowly apply

pressure by rolling the bumper into the

track.

6. Refrigeration

Refrigerant lines should be sized as shown on the

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

Hussmann’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 product 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 section. Never use two water seals in series in

any one line. Double P-TRAPS in series will cause a

lock and prevent draining.

3. Always provide as much down hill slope (“fall”) as

possible; 1/8” per foot is the preferred 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 provide the “fall” necessary for

good drainage.

5. Provide a suitable air break between the flood rim of

the floor drain and outlet of condensate drain. 1” is

ideal.

6. Prevent condensate drains from 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 between

a refrigerator and a wall), provide means to

prevent freezing. The water seal should be

insulated to prevent condensation.

Refrigerant Type

The standard refrigerant will be R-404A 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 1/2” (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.

refrigeration legend furnished by the store. Install P-TRAPS

(oil traps) at the base of all suction line vertical 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 Q2-SS technical data sheet for the appropriate

settings for your merchandiser. Maintain these

parameters to achieve near constant product

temperatures. Product temperature should be measured

first thing in the morning, after having been refrigerated

overnight. For all multiplexing, defrost should be time

terminated. Defrost times should be as directed in the

Q2-SS technical data sheet. The number of defrosts per

day should never change. The duration of the defrost

cycle may be adjusted to meet conditions present at

your location.
