1. Introduction

This instruction manual provides all the necessary information regarding:

 Use of the refrigeration unit
 Technical specifications
 Installation and handling
 Operator procedures and instructions
 Maintenance operation

The manual is to be considered an integral part of the refrigeration unit and
should be stored in a safe place for further consultation for the working
life of the refrigeration unit.

The manufacturer cannot be held liable in the following cases:

■ Improper installation (not in accordance with the guidelines indicated herein)

■ Misuse of the refrigeration unit

■ Power supply defects

■ Improper or inadequate maintenance

■ Unauthorized modification or tampering

■ Use of non-original (NON-OEM) spare parts

■ Partial or total failure to comply with the instructions

All electrical equipment can be hazardous to health. Current standards and
legal requirements must be complied with during the installation and use of
any equipment.

2. Use of the Equipment

The refrigeration units are for storing and preserving fresh, perishable food

and drinks.

The operating temperature for refrigeration is:

■ Between 45°F and 33°F at room temperature of 109°F and 60% RD

The operating temperature for frozen food maintenance is:

■ Between -1°F and -8°F at room temperature of +109°F and 60% RD

3. Technical Features

The refrigeration unit is a ventilated system; the evaporator is in a separate
insulated box on the top. All the materials used in the manufacturing of this
unit are guaranteed to be suitable for use with food items. The gases used in
the refrigerator are R134a; in the freezer for frozen food maintenance the gas
is R404a. The refrigerating circuit is in compliance with current industry
standards.

4. Operation

The gas in the refrigerating circuit is first compressed, liquefied and then
evaporated in the ventilated evaporator, located on the top of the
refrigeration unit.
This cycle involves the absorption of heat from the air in the
refrigeration unit compartment. The heat produced is then dissipated to the
outside environment by a condenser unit located on the top of the refrigeration
unit.

5. Control Panel/Digital Display

A digital display thermostat and a main power switch are on the top panel
of the refrigeration unit operate the refrigerator.

The main power switch is for turning on the power supply.

The green power light comes on to indicate that the unit is connected to the
main electricity source and to start operation.

The green power light turns off to indicate that the unit is disconnected and is
not operable. The digital display thermostat is for the regulation of all
parameters to provide the correct operation of the refrigeration unit. Please

consult all parameters in the digital display thermostat section of this manual.

6. Handling

The refrigeration arrives in PET film and packed in a cardboard box on a
wood pallet.

The refrigeration unit must be transported and handled with care.

!

Never place a refrigerator on its side or turn it on its side or
turn it upside down as this may damage or impair
operation of the unit. Saturn cannot be held liable for any
damage or defects arising directly or indirectly from
improper handling of the equipment or non-compliance
with the safeguards illustrated above.

7. Installation Procedures

Place the refrigeration unit in the coolest and best





ventilated part of the room.



Don’t install the refrigeration unit near heat and direct





sunlight sources.



Remove the straps securing
packing. Remove the cardboard covering. Remove
the PET protection film.



Clean the refrigerator with mild detergent and then dry
it with a soft cloth.

8. Connecting to the Main Power Supply

Qualified professionals must carry out this operation.

!

The refrigeration units are supplied complete with
a power supply cord for connection to the
main power supply. A thermomagnetic circuit breaker
(not supplied) must be installed between the main power
point and the power supply cord of the refrigeration unit.

Before proceeding make sure that:

refrigeration unit being installed

 The electric system to which the refrigeration unit is connected is

made in compliance with current standard requirements

 The electric connections and the installation of the thermomagnetic circuit

Connection steps:

 Install a thermomagnetic circuit breaker that can manage the output of the

unit being installed

 Connect the refrigeration unit to the thermomagnetic circuit breaker outlet
 Check that the refrigeration unit is in order as demonstrated by the

control power light turning on

9. Maintenance Instructions

The smooth operati on and life o f the equipme nt are mainly determined by correct
and regular maintenanc e.

Cleaning:

Regular cleaning of the refrigeration unit is strongly recommended
each month. Please follow the instructions below.

Disconnect the refrigeration unit power supply cord from the

!

mains prior to carrying out any type of cleaning operation.

Cleaning the refrigeration unit surface:

Clean the refrigeration unit with mild detergent and then dry
with a soft cloth. Do not use abrasive detergents!

Cleaning the inside of the refrigeration unit:

Clean the inside area at least a minimum of once a
month with a detergent suitable for use with food items.

Cleaning the condenser:

For an efficient operation of the refrigeration unit, it is
advisable to clean the condenser regularly approximately
every 4 months with a dry brush or vacuum cleaner.

Troubleshooting

My refrigeration unit has stopped working (light off):

 Power supply failure

Solution:

 Check that the plug is properly connected
 Check that the on/off switch is set to “on”
 Check that the main voltage power is on

The temperature of my refrigeration unit has increased:

 The unit may be located too close to a heat source



The condenser is dirty or closed

Solution:

 Move the heat source further away from the unit
 Clean the condenser

Operating Instructions

1. New, upright air-cooling refrigeration units should
be opened and ventilated before use. After
ventilation, you should use warm water to clean the
interior.

2. After connecting the power supply, press the
“POWER” switch on the control panel (Green

Indicator Light ON) and the refrigeration unit’s power will turn on. The

microcomputer controller, installed in the control panel, can automatically
adjust the temperature ranges. This intelligent digital display works as
such: If the temperature increases and reaches set point plus differential,
the compressor is started and then turned off when the temperature
reaches the set point value again.

Front Panel Commands – Digital Display
