INSTALLATION - Safety Information

INSTALLATION

Safety Information

When using any electrical appliance, safety precautions should always be

observed. Read these instructions carefully and retain for future reference.

• This appliance is not intended for use by persons (including children) with

reduced physical, sensory or mental capabilities, or lack of experience and

knowledge, unless they have been given supervision or 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.

•DoNOT use this appliance for other than its intended use.

•DoNOT cover the grilles or block the entry or exhaust of airflow by placing

objects up against the refrigeration unit.

•DoNOT probe any opening.

• Only use this appliance with voltage specified on the rating label.

• Ensure adequate ventilation of the SKOPE refrigeration unit.

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

• Regulations require that all electrical work be carried out by authorised

persons. For your own safety, and that of others, ensure this is done.

• If the supply cord becomes damaged, it must be replaced by a SKOPE

authorised service agent, or similarly qualified person, in order to avoid a

hazard.

• If the refrigeration unit is required to be installed or removed from the cabinet,

ensure all necessary safety precautions are observed.

• This chiller is not designed to be stable in motion. Exercise caution when

moving or transporting this chiller.

Caution:

Disconnect the cabinet from the mains power supply before attempting any

cleaning or maintenance.

INSTALLATION - Fitting the Legs or Castors

Fitting the Legs or Castors

Packed inside the cabinet is a set of adjustable height legs and a set of adjustable

height castors. Either of these sets can be fitted to the cabinet depending on

specific height and manoeuvrability requirements. The legs or castors should be

fitted to the base of the cabinet before final positioning of the chiller.

Adjustable Legs

The adjustable legs screw into the castor mounting plates attached to the bottom of

the cabinet. The adjustable legs can adjust the cabinet height up to 30mm.

To adjust the height of each leg, turn the black plastic foot at the bottom of the leg

counter-clockwise to raise the height or clockwise to lower (see Figure 2 below).

Figure 1: Castor Mounting Plate Figure 2: Adjustable Leg

INSTALLATION - Fitting the Legs or Castors

Adjustable Castors

The adjustable castors screw into the castor mounting plates attached to the bottom

of the cabinet. The two lockable castors should be fitted to the front of the cabinet

(see Figure 3 below) and the non-locking castors fitted to the rear (see Figure 4

below). The adjustable castors can adjust the cabinet height up to 15mm.

To adjust the height of each castor, loosen the lock nut and turn the castor counter-

clockwise to raise the height or clockwise to lower. Re-tighten each lock nut after

final adjustment has been made.

Castor Mounting Plates

If the chiller is intended to be mounted on a plinth, the castor mounting plates

attached to the bottom of the cabinet can be removed to provide a flat bottom. Each

castor mounting plate is held in place by four pozi-drive hexagon head screws (see

Figure 1 on page 7).

INSTALLATION - Positioning the Cabinet

Positioning the Cabinet

Location

When positioning the cabinet, avoid direct sunlight and warm draughts etc. The

cabinet must NOT be situated where it is affected by warm or hot air from adjacent

equipment, as this will compromise the airflow and performance of the chiller.

The cabinet must be positioned on a level surface for the doors to shut and seal

correctly, and to prevent the condensate tray from overflowing. Adequate allowance

should be made for door opening.

Always ensure that the top of the cabinet is shielded from impact and moisture, with

either a SKOPE provided bench top or with a custom or existing bench top.

Ventilation

For efficient operation of the chiller, it is essential that adequate ventilation be

provided around the front of the refrigeration unit. Normal operating conditions

should not exceed 40°C at 65% RH.

It is critical that the hot refrigeration exhaust air is not restricted and that it can easily

flow out and away from the front of the cabinet.

Never store cardboard cartons or other items in front of the refrigeration unit. The

ventilation slots in the unit front cover must be kept clear at all times.

When installing the cabinet:

• Avoid direct sunlight and warm draughts etc.

• Ensure adequate ventilation around the front of the refrigeration unit.

• Allow adequate space for the door/s to open fully.

• Ensure the cabinet is positioned on a level surface so the door/s shut and seal

correctly and to prevent the condensate tray from overflowing.

• The self-closing door/s have internal torsion bars, pretensioned at the factory,

and should not require any further adjustment.

• Do not overload the power supply. See the rating label inside the cabinet for

power supply and current draw.

Warning:

The ventilation slots in the unit front cover must be kept clear at all times.

INSTALLATION - Positioning the Cabinet

Power Supply

The chiller is supplied with a 1.8m flexible power cord and plug, which for transit

purposes is located inside a compartment in the rear of the cabinet (see Figure 5

below).

Before final positioning of the chiller, pull the power cord out from the rear

compartment and connect to the power supply. For convenience, any surplus cord

length may be left inside the cabinet compartment.

Once the chiller has been installed it can be disconnected from the mains power

supply by turning off the cabinet isolating switch and unplugging the unit supply

isolation flex, located inside the refrigeration unit compartment (see Figure 6

below).

Warning:

Do NOT overload the power supply. See the rating label inside the cabinet for

power supply and current draw.
