instruction concerning use of the appliance by a person responsible for

their safety. Children should be supervised to ensure that they do not

play with the appliance.

Do not use this appliance for other than its intended use.

Do not insert fingers/foreign objects into any holes.

Only use this appliance with the voltage specified on the cabinet rating

label.

Ensure the appliance has adequate ventilation as this is essential to

economical, high performance.

Be careful not to touch moving parts and hot surfaces.

For your own safety and that of others, ensure that all electrical work is

done by authorised personnel.

If the power supply flexible cord becomes damaged, it must be replaced

by an authorised service agent or similarly qualified person in order to

avoid a hazard.

Ensure all necessary safety precautions are observed during installation

or removal of the refrigeration unit.

The appliance is not designed to be stable while in motion. Use extreme

caution when moving or transporting it.

Do not store explosive substances such as aerosol cans with a

flammable propellant in this appliance.

If the cabinet is to be scrapped, ensure the cabinet is unplugged from

the power supply and cut off the mains flex close to the back of the

cabinet. Be mindful of the risk of animals or children becoming trapped

in the appliance – either remove or secure doors if necessary.

Refrigerant must be removed by a qualified service person and the

cabinet recycled/disposed of in accordance with local regulations.

WARNING

Always disconnect the chiller from the mains power supply

before cleaning or maintenance.

CAUTION

Never overload the power supply, which could damage the

User Manual

Positioning the Chiller

Climate Class The chiller is designed to operate within a climate class 3 environment (25°C

@ 60% relative humidity).

Location Select a suitable location for the chiller away from direct sunlight and heat

sources, e.g. radiators, baseboard heaters, cooking appliances.

This chiller is intended to sit on a raised benchtop. Ensure the bench will

support the chiller which could weigh up to 120kg when fully loaded.

The front door (electronic controller side) is fitted with a door switch. Position

the chiller so that the front door opens to the customer side of the benchtop.

This enables the door switch to detect customer door openings.

Ventilation Ensure adequate ventilation is provided around the chiller. The chiller is

designed for free-standing installation only. Do not place the chiller in a

recess or another cabinet.

Installation

Guidelines

When installing the chiller:

Remove all packaging material from the inside and outside the chiller.

Ensure the chiller is positioned on a level surface so the doors shut and

seal correctly, and to prevent the condensate tray from overflowing.

Ensure the installation surface is capable of supporting the fully loaded

chiller.

Allow adequate space for door opening. The self-closing doors have

pre-tensioned internal torsion bars.

Do not overload the power supply (see the rating label inside the

cabinet for power supply and current draw information).

Position the front door (electronic controller side) towards the customer.

Power Cord The chiller is fitted with a 2 metre flexible power cord with a 3-pin plug, which

exits the front of the refrigeration system.

Levelling Adjust the four stabiliser feet (see image below) to ensure the chiller sits on

a level surface so that both doors shut and seal correctly. Turn the stabiliser

foot clockwise to raise and anti-clockwise to lower the cabinet.

IMPORTANT

Ensure the controller faces the customer side of the benchtop.

2 Operation

Automatic Start-up

After the chiller has been positioned in a suitable place, plug it in and check

the following activity.

Loading Product

Let the chiller run for 30 minutes before loading it with product the first time.

When loading the cabinet shelves with product:

Allow adequate air space around each item to ensure even cooling and

efficient operation of the chiller.

Remove some product if the shelves are flexing. The maximum loading

for each shelf is 25kg.

Do not let anything overhang the shelves, this might stop the doors from

shutting or even break something.

Door Lock

The chiller is fitted with security door locks. Use the supplied keys to lock

and unlock the door as necessary.

Item Activity

Condenser fan The condenser fan starts immediately and can be heard.

Evaporator fan

The evaporator fan will start after a few seconds. To verify,

check that the fan light is flashing on the electronic

controller. The evaporator fan turns off when the front door

(electronic controller) is opened and turns on again when

the front door is closed.

Sign and interior LED

lighting

The lights that illuminate the sign and cabinet interior will

come on when the chiller is turned on.

Compressor

The compressor will start after a few minutes. To verify,

check that the compressor light is flashing on the electronic

controller. The compressor turns off when the product

temperature reaches +2°C and turns on when the product

temperature rises to +5°C.

User Manual

Electronic Controller

Introduction The electronic controller controls and displays the chiller temperature, and

signals temperature alarms. It uses temperature probes and a door switch

to collect data and runs the chiller accordingly. The electronic controller

automatically switches the chiller between ‘Day’ and ‘Night’ modes

depending on chiller usage. The electronic controller is pre-programmed

and requires no initial setup or additional programming. SKOPE does not

recommend that the settings be changed unless it is absolutely necessary.

To ensure efficient operation, the electronic controller forces a defrost cycle

when required.

Faceplate Because the electronic controller plays such an important role, it’s helpful to

know the parts of the faceplate you may use.

Door Switch The front door (electronic controller side) is fitted with a door switch which

tells the electronic controller when the door is opened and closed. If the door

is opened for an extended period an alarm will sound. Press the alarm mute

button on the electronic controller to mute the alarm.

No. Item Description

1Alarm Mute (up): Mutes the audible alarm buzzer.

3 Maintenance

Cleaning

Many commercially available cleaning products contain solvents that may

damage the plastic components of the chiller and cause them to crack. Do

not use abrasive or corrosive cleaners or boiling water.

Wash with warm water and wipe down the chiller with a soft cloth or sponge,

then rinse with clean warm water and dry with a soft cloth. If required, lift up

and remove the shelves to help with cleaning. Do not flush the cabinet with

water.

Shelves

Adjusting the

Shelves

The chiller is supplied with three wire shelves which may be positioned at

different heights to suit various products. Each shelf is held in place with four

shelf clips which engage in the shelf support strips.

To adjust the cabinet shelves

Lighting

The chiller is lit by long life LED strip lighting. If any of the lights fail, contact

an authorised service agent to service the lights.

CAUTION

Isolate the chiller from the power supply before cleaning.

1. Remove the shelves from the chiller.

2. Remove the shelf clips from the four shelf support strips at each corner of the

chiller interior.

3. Establish the desired position for the shelves and securely engage a shelf clip

in each of the shelf support strips.

4. Sit the shelves onto the shelf support clips.
