SHIPPING DAMAGE CLAIM PROCEDURE

NOTE: For your protection, please note that

equipment in this shipment was carefully

inspected and packed by skilled personnel

before leaving the factory. The transportation

company assumed full responsibility for safe

delivery upon acceptance of this shipment.

* We cannot assume responsibility for

damage incurred in transit. We will, however,

be glad to furnish you with the necessary

documents to support your claim.

All Montague products are factory tested for

performance and are free from defects when

shipped. The utmost care has been taken in

crating this product to protect against damage in

transit.

You should carefully inspect your Montague unit

for damage during delivery. If damage is de-

tected, you should save all the crating mate-

rials and make note on the carriers Bill of Lading

describing the damage. A freight claim should be

filed immediately. There is a fifteen (15) day limit

to file freight damage with the carrier. (to

verify)

Care should be taken during unloading so the

equipment is not damaged while being moved

into the building.

1. Visually inspect the exterior of the package

and skid or container. Any damage should be

noted and reported to the delivery carrier

immediately.

2. If damaged, open and inspect the contents

with the carrier.

3. In the event the exterior is not damaged, yet

upon opening, there is concealed damage to

RECEIVING & INSPECTING

connections. See wiring diagram shipped

with the unit on the compressor compartment

behind the louver panel for electrical rating.

E. REFRIGERATION LINES (Remote units

only)

WARNING: REFRIGERATION LINES ARE

SHIPPED UNDER PRESSURE. USE CAUTION

WHEN OPENING LINES.

F. ON REMOTE UNITS. Refrigeration lines for

suction and supply are located on the back

of the unit. The suction line is marked

“suction” and 3/8 copper tubing. The liquid

supply line is 1/4” copper. If upon opening

lines, no release of charge is evident, contact

your local authorized service agent immedi-

ately.

Cut refrigeration tubing with appropriate tool

and de-burr end of the tube. Clean tubing prior

brazing connection. Use Silfos 5% refrigerant

line brazing or better.

A. TEMPERATURE CONTROL SETTINGS:

On both Self-Contained and Remote

Refrigerated units, temperature Control

should be set 35°F with a 5°F dierenal. This

display should read between 35°F to 40°F . The

temperature control seng is “locked” to avoid

unauthorized adjustments. Therefore,

adjustments to the set point must be made by an

authorized service technician.

B. ON FREEZER BASE UNITS: The temperature

control should be set at 0°F with 5°F dierenal.

Temperature display should read between 0°F

and 5°F

C. The temperature control is the actual

thermometer of the unit, it does display the

actual temperature of the storage cabinet.

Allow cabinet to reach normal operang

temperature before loading (approximately) 20

minutes for refrigerator and 45 minutes for

freezer. If the storage cabinet is overloaded with

warm food products, a certain amount of me is

required to remove heat from items before

operang temperatures can be maintained.

The system is designed for storage of

refrigerated or frozen products.

D. DEFROST TIME SETTINGS: All models are

provided with an electronic temperature control

which have a built-in defrost system, which is

factory set as well as the temperature sengs.

Any change made to the seng must be made

by a qualied or authorized service technician.

E. SHUTDOWN FOR EXTENDED PERIODS: If the

units are not to be used for an extended period

of me, disconnect the electrical power supply

and remove the drawers from the storage

cabinet. As soon as cabinet has warmed to room

temperature, wipe out the base interior.

AVAILABLE DRAWER CONFIGURATION

A. CLEANING: STORAGE CABINET

WARNING: DISCONNECT ELECTRICAL

POWER SUPPLY BEFORE CLEANING ANY

PARTS OF THE UNIT.

B. STORAGE CABINET: Remove the drawer

from the drawer frame modules, use warm

soapy water to clean storage cabinet doors.

NEVER use cleaners containing gritty, abrasive

materials, bleach or harsh chemicals. Rinse

thoroughly and dry with a clean soft cloth. Al-

ways rub in the same direction as the grain pat-

ter of the stainless steel.

WARNING: DISCONNECT ELECTRICAL

POWER SUPPLY BEFORE CLEANING ANY

PART OF THE UNIT

The condensing unit coil must be cleaned

regularly on self-contained models for optimal

performance. The operating environment will

affect the required frequency of cleaning.

However, the condenser should be cleaned at

minimum of once every 6 months. Air must be

able to freely circulate through the condenser.

Unit performance and operating efficiency are

significantly affected by the amount of the air

passing through the condenser. Condenser fins

that are clogged with dirt and grease greatly

reduce required heat transfer to air flow. Failure

to keep the condenser clean may cause

premature compressor failure, which will not be

covered by the warranty. The condensing unit is

located behind the louvered panel in the

compressor compartment. Remove panel by

lifting it up and pulling the bottom out. Carefully

clean dirt and lint from the condenser coil using

a vacuum cleaner or soft brush. Do not use a

wire brush. An approved condenser degreaser

must be used to remove grease. Replace

louvered panel by installing top of the panel into

track and pushing in the bottom so it fits inside

the opening, reconnect electrical supply.

D. EVAPORATOR COILS:

WARNING: DISCONNECT ELECTRICAL

POWER SUPPLY BEFORE CLEANING ANY

PARTS OF THE UNIT.

Evaporator coils should be cleaned as required

for optimal performance.

The evaporator coils are located in the storage

cabinet behind the coil cover. With a 1/4” driver,

remove 2 screws holding the cover and remove

cover. Clean evaporator coils with a vacuum

cleaner or soft brush. Replace coil cover . Re-

connect electrical supply.

MAINTENANCE PROCEDURES

PROBLEM POSSIBLE CAUSE

1. Compressor fails to operate

 Prolonged and/or frequent door openings or

door(s) ajar

 Excessive load of warm food placed into

lower storage cabinet

3. Lower storage cabinet not holding

temperature
