PRE-INSTALLATION PROCEDURES

Inspection For Shipping Damage

You are responsible for filing all freight claims with the delivering truck line. Inspect all
cartons and crates for damage as soon as they arrive. If damage is noted to shipping
crates, cartons, or if a shortage is found, note this on the bill of lading (all copies) prior to
signing.

If damage is discovered when the case is uncrated, immediately call the delivering truck
line and follow-up the call with a written report indicating concealed damage to your
shipment. Ask for an immediate inspection of your concealed damaged item. Crating
material must be retained to show the inspector from the truck line.

INSTALLATION INSTRUCTIONS

Locating The Display Case

The case should be located where it is not subjected to the direct rays of the sun, heating
ducts, grills, radiator, or ceiling fans, nor should it be located near open doors or main
door entrances. Also, avoid locations where there is excessive air movement or air
disturbances and avoid high humidity locations such as near cases with water misting or
fogging devices.

The case requires a minimum of 24” of clearance at the rear of the unit for air discharge.
Do not locate case with back tight against a wall. No clearance is needed on the sides of
the unit.

Removing Case From Shipping Skid

CAUTION: Do not push against the curved glass, end glass, doors, or doorframes when removing

the case from the skid or moving the case. Case damage or glass breakage could
result.

Move the case as near as possible to the final location before removing it from the

shipping skid.

Remove the screws and brackets that secure the case to the skid.

Removing Packaging Material

Remove the brackets that held the case to the shipping skid.

Remove the shipping tape that secures the doors and lift-up glass. If it is necessary to remove tape residue
from plastic materials, use cleaning compounds recommended in the cleaning section of this manual.

Leveling The Case

The case must be level for proper drainage of defrost water to the condensate evaporator
or floor drain.

Check the level of the case along the front rail and along the top of the display pan.
Adjust levelers (4 on 454, 6 on 654, 854, and 1054) as needed to level the case.

NOTE:

The leveled case must be sealed to the floor using an NSF Listed Sealant.

Grill Removal

DANGER: Electric shock hazard. Do not operate unit with panels removed.

The rear grill requires removal for case installation. Rear grill is secured with self­tapping machine screws.

Grill must be in place for proper operation of the case. Grill must be reinstalled after case
installation.

Condensate Evaporator

NOTICE: During normal defrost cycles, steam from the condensate evaporator may be

visible around the case.

(Remotes Only With Optional Electric Condensate Evaporator Pans)

Self-contained cases (DC & DM) use a hot gas condensate evaporator.

The condensate evaporator is located behind the rear grill panel and is accessible from the
rear of the case.

Make sure that the drain line has not been dislodged during shipment and that the drain
terminates property over the water reservoir.

Fish cases (DF), self-contained and remote, must have the drain line plumbed into a
floor drain.

Lights

The ballasts used on this case allow removal of one or more top lights, or shelf lights if so
equipped, without affecting the remaining lights.

ELECTRICAL INFORMATION &
GROUNDING

This Case Must Be Grounded

DANGER:

display case can result in severe injury or death.

Only a licensed electrician must perform all case electrical connections.

All electrical wiring hookups must be done in accordance with all applicable local, regional, or
national electrical standards.

A separate circuit for each display case is recommended to prevent other appliances on the same
circuit from overloading the circuit and causing malfunction.

The electrical service must be grounded upon installation.

This unit is designed for permanent connection to a power source. See the electrical data plate,
next to electrical junction box, for proper circuit size and wire ampacity.

The electrical field connection 2 x 4 box is accessible from the rear of the case and is located in
the right (as viewed from case rear). See details below.

Defrost Timer Control

Note your new Maxi Deli unit is equipped with a 24 hr / 7 day a week digital electronic defrost timer. This
timer can be programmed to turn the compressor off for a preset time to cause the coils to warm up and
defrost.

The timer was factory pre-set for central time. You will need to change this for your Time Zone. Note

that the time of day must be set for the unit to operate.

Some default defrost were also set at the factory. You need to determine if these will be sufficient for
your application of the equipment. If the unit has been off for more than 5-10 days you may have lost the
programming of these defaults. If you hit the reset switch at the bottom of the timer you can clear all
preset defrosts.

You do need to have a time set on the clock and the I/O (on/off) set to the on position for the
compressor to run. Note that this defrost timer is located behind the switch / control panel at the back of

the unit. (See Photo below.) Note you may have to plug the unit in and turn the power switch on to
charge the battery for 6 to 8 hours if the battery has completely run down. Once you have the battery in
the timer charged and the clock set, the timer should maintain its programming for up to 5 days if the unit
is turn off or there is a power outage.

Note that on DM’s and DC’s the condenser fan runs all the time. This does not mean the compressor is
running. The Compressor is cycled on a timer based on the Refrigeration Control, located on the
switch panel at the back of the case. (See Photo below.) Note that a 1 setting on this control cycles the
compressor for approximately a 10 minute run time. A 5 setting on this control will be approximately a 50
minute run time. Note that the higher the setting the colder the case will get if you don’t have a problem
with the coils icing up. The off time is factory set to get the coils up to about 42 degrees before the time
cycle re-starts.

This 24 hr / 7 day a week digital electronic defrost timer is used to initiate defrosts to keep the evaporator
coils from icing up. You need to determine what defrosts will be required throughout the week to keep the
coils clear and maintain the case temperature that your application requires. Note that some ice
formation and ice drips are normal on the top gravity coil.

Following are the programming instructions for the defrost timer.
This timer allows you to set up to 6 “on” and 6 “off” settings (defrosts) per day Mo thru Su.
