SAFETY INFORMATION

PROPER DISPOSAL OF THE DISPLAY CASE

DANGER!

RISK OF CHILD ENTRAPMENT

USE OF EXTENSION CORDS

NEVER USE AN EXTENSION CORD! TRUE will not warranty any display case that has been connected to an

extension cord.

Child entrapment and suffocation are not problems

of the past. Junked or abandoned display cases

are still dangerous… even if they will sit for “just a

few days.” If you are getting rid of your old display

case, please follow the instructions below to help

prevent accidents.

Before You Throw Away Your Old Display Case:

•Take off the doors.

•Leave the shelves in place so that children may

not easily climb inside.

Refrigerant Disposal

Your old refrigerator may have a cooling system

that uses “Ozone Depleting ” chemicals. If you are

throwing away your old refrigerator, make sure the

refrigerant is removed for proper disposal by a

qualified service technician. If you intentionally

release any refrigerants you can be subject to

fines and imprisonment under provisions of the

environmental regulations.

Before your new display case is connected to a

power supply, check the incoming voltage with a

voltmeter. If anything less than 100% of the rated

voltage for operation is noted, correct immediately.

Have the circuit checked by a qualified electrician

to make sure it is properly grounded.

The display case should always be use it’s own indi-

vidual electrical circuit, which has a voltage rating

that matches the rating plate.

This provides the best performance and also pre-

vents overloading building wiring circuits which

could cause a fire hazard from overheated wires.

For models with standard power cord.

The power cord of this appliance is equipped with

a 3-prong (grounding) plug which mates with a

standard 3-prong (grounding) wall outlet to mini-

mize the possibility of electric shock hazard from

this appliance.

Have the circuit checked by a qualified electrician

to make sure it is properly grounded.

If the outlet is a standard 2-prong outlet, it is your

personal responsibility and obligation to have it

replaced with the properly grounded 3-prong wall

outlet.

The display case should always be plugged into it’s

own individual electrical circuit, which has a volt-

age rating that matches the rating plate.

This provides the best performance and also pre-

vents overloading building wiring circuits which

could cause a fire hazard from overheated wires.

Never unplug your display case by pulling on

the power cord. Always grip plug firmly and pull

straight out from the outlet.

Repair or replace immediately all power cords that

have become frayed or otherwise damaged. Do not

use a cord that shows cracks or abrasion damage

along its length or at either end.

When removing the display case away from the

wall, be careful not to roll over or damage the

power cord.

HOW TO CONNECT ELECTRICITY

Hard wiring is required on specific Display Cases.

Models standard with power cords: Do not, under any circumstances, cut or remove the third (ground) prong

from the power cord.

For personal safety, this appliance must be properly grounded.

WARNING!

USE OF ADAPTER PLUGS

NEVER USE AN ADAPTER PLUG!

SAFETY INFORMATION

NEMA plugs

TRUE uses these types of plugs.

If you do not have the right outlet

have a certified electrician install

the correct power source.

Step 5

A. The compressor is ready to operate. Plug in the

display case.

B. Check the temperature control setting in the

lower right of the cabinet backside. The set-

ting should be at No. 3 position to maintain an

approximate temperature of 38°F (3.3°C). Set

defrost time clock to the correct time of day.

Allow unit to function several hours, completely

cooling cabinet before changing the control set-

ting.

C. Excessive tampering with the control could lead

to service difficulties. Should it ever become

necessary to replace temperature control, be

sure it is ordered from your True dealer or rec-

ommended service agent.

D. Good air flow in your True unit is critical. Be

careful not to overstock product or block air

vents.

E. Verify that the cabinet lights are working.

Bakery cases are shipped with light switches in

the "on" position. The toggle switch is located

lower right corer at the rear.
