It collects ﬁrst in low areas but can be circulated by

the fans. If propane gas is present or even suspected,

do not allow untrained personnel to attempt to ﬁnd

the cause.The propane gas used in the unit has no

odor. The lack of smell does not indicate a lack of

escaped gas. If a leak is detected, immediately evacuate

all persons from the store, and contact the local ﬁre

department to advise them that a propane leak has

occurred. Do not let any persons back into the store

until the qualiﬁed service technician has arrived and

that technician advises that it is safe to return to the

store. No open ﬂames, cigarettes or other possible

sources of ignition should be used inside or in the

vicinity of the units.

1. Added new medium temp. models

REVISION B — FEBRUARY 2019

1. Added new low temp. models; updated

Section 2

REVISION A — MARCH 2018

1. Original Issue

Do NOT remove shipping crate until

the merchandiser is positioned for

installation.

Excessive ambient conditions may

cause condensation and therefore

sweating of doors. Facility operators

should monitor doors and oor

conditions to ensure safety of

persons.

A 4-inch (102 mm) space between

the rear of the merchandiser and wall

must be maintained for air circulation.

However, in high ambient conditions,

sweating may still occur. If this

happens install a method of forced

ventilation such as a fan ventilation kit.

UL LISTING

These merchandisers are manufactured to meet ANSI/

UL 471 standard requirements for safety. Proper

installation is required to maintain the listing.

FEDERAL / STATE REGULATION

These merchandisers at the time they are

manufactured, meet all federal and state/ provincial

regulations. Proper installation is required to ensure

these standards are maintained. Near the serial plate,

each merchandiser carries a label identifying the

environment for which the merchandiser was designed

for use. In compliance with DOE 2017, standard

low temp Reach In cases with Innovator I Doors are

equipped with an anti-sweat controller that maintains

the door heat at a level that meets DOE energy limits.Any

factory or eld-installed anti-sweat controller applied

to a low temp Reach In case with Innovator I Doors

must be programmed to cycle the heaters at no more

than 50% run time at design conditions of 75degrees,

55% RH for frozen food operating condition.

ANSI/NSF-7 Type I – Display Refrigerator / Freezer

Intended for 75°F (24°C) / 55%RH Ambient Application

ANSI/NSF-7 Type II – Display Refrigerator / Freezer

Intended for 80°F / 55%RH Ambient Application

ANSI/NSF-7 – Display Refrigerator

Intended for Bulk Produce

LOCATION

These merchandisers are designed for displaying

products in air conditioned stores where temperature is

maintained at or below the ANSI/NSF-7 specified level

and relative humidity is maintained at or below 55%.

Placing refrigerated merchandisers in direct sunlight,

near hot tables or near other heat sources could

impair their efficiency.

Like other merchandisers, these are sensitive to

air disturbances. Air currents passing around

merchandisers will seriously impair their operation. Do

NOT allow air conditioning, electric fans, open doors

or windows, etc. to create air currents around the

merchandisers.To prevent sweating on the exterior

surfaces of merchandisers, there must be aminimum

clearance of 4 inches (102 mm)between the

merchandisers and other fixtures or walls. Product

should always be maintained at 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 the life of the product.

SHIPPING DAMAGE

All equipment should be thoroughly examined

for shipping damage before and during unloading.

This equipment has been carefully inspected at our

factory. Any claim for loss or damage must be made

to the carrier. The carrier will provide any necessary

inspection reports and/or claim forms.

Apparent Loss or Damage

If there is an obvious loss or damage, it must be noted

on the freight bill or express receipt and signed by the

carrier’s agent; otherwise, carrier may refuse claim.

The carrier will supply necessary forms.

Concealed Loss or Damage

equipment is uncrated, a claim for concealed damage

is made. Upon discovering damage, make request in

writing to carrier for inspection within 15 days and

retain all packing. The carrier will supply inspection

report and required claim forms.

MERCHANDISERS SHIPPED WITH

END INSTALLED

If the case was shipped with the end installed, two long

bolts were used to hold the shipping brace to the end.

If the shipping bolts are reinserted after removing the

brace, they will extend into the product area and may

damage the coil. Therefore, be sure To replace These

bolTs wiTh The shorTer bolTs provided.

Be careful not to damage the factory-installed end

while moving the merchandiser. Make sure that

tools are positioned past the end and beneath the

merchandiser’s support bar.

SHIPPING BRACES

NOTE: Begin lineup leveling from the highest point

of the store floor.

Place shims under the rail and make sure that they

are positioned at a base component (crossbar). This

transfers the weight directly from the loaded case

through to the floor.

Placing shims at other locations will cause uneven

distribution of weight leading to piping leaks, as well

as sagging or wracked doors.

Bottom front supports must be shimmed if not in full

contact with the floor.

DOOR ADJUSTMENT

After leveling and joining the merchandisers,

adjust and level doors according to manufacturer’s

instructions shipped with each product. Factory

settings may be lost due to vibration during shipment.

INSTALLING SPLASHGUARD

BRACKETS

1. Attach splashguard retainer and splashguard

retainer support to splashguard support bracket

using two screws per bracket.

2. Install splashguard support brackets underneath

case.The leveling brackets have a maximum

extension of one (1) inch (25 mm) for uneven

floors.

DO NOT place shims under splashguard brackeTs.

NOTE: Install splashguard support brackets

before piping case.

JOINING

Sectional construction means that two or more

merchandisers may be joined in line yielding one long

continuous display requiring only one pair of ends.

Joining kits and instructions are shipped with each

merchandiser.

To join like fixtures, a joining kit is required. To

join unlike fixtures, or like fixtures operating at

different temperatures, a 2inch (51mm) partition kit

is required. To join same temperaturemerchandisers

on different defrost cycles, a plexiglass partition kit is

required.

all joinTs musT be air-TighT To prevenT formaTion of

ice or condensaTion.
