INSTALLATION

Setting Up

WARNING
Improper installation, adjustments, alternations, service, or maintenance can cause property damage, injury, or death.

Handling

To prevent injury or damage to the unit, take the proper precautions when moving the cabinet.
For larger cabinets moving equipment such as a forklift or pallet trolley should be used (the forks should be completely under the pallet)
Ensure that the cabinet is always level.

Unpacking

Before and after unpacking, the cabinet should be checked for damage.
If there is any damage, please contact the distributor and/ or manufacturer within 24-48 hours of receipt and before connecting to the mains.
The cabinet is supplied fully assembled.
Remove all protective plastic film, tapes, ties, and packers before installing and operating.
Clean off any residual from the interior / exterior of the cabinet using a clean cloth and warm soapy water.

WARNING
Danger of suffocation due to packing material and plastic film. Do not allow children to play with packaging material.
Take the packaging material to an official collection point.

Positioning

Ensure that the cabinet is on a horizontal and level floor.
- If your cabinet comes with front levelling feet, you may adjust them to ensure the cabinet is level.
- If the cabinet is on castors the front two breaks on the castors must be engaged to ensure the cabinet stays in the correct position.
Do not position the cabinet in:
- Wet areas
- Near heat and / or steam sources
- Near flammable substances
Ensure there is 60mm ventilation space on sides, 100mm on the rear, and 200-300mm on top of refrigerator for proper air flow. See example below.
The cabinet should not be installed in any manner that would impede normal service access.
Please wait at least 2 hours before switching the cabinet ON as this will allow the refrigeration gas in the refrigeration system of the cabinet to settle due to movement and handling during freight.

Large Cabinets

Refrigeration

__

| WARNING
---|---

System charged with flammable refrigerant.
If there is a suspected refrigerant leak, turn the cabinet off and contact Nuline Refrigeration if under warranty; if no longer warranty contact your preferred qualified services technician.

This cabinet is fully operational once it leaves our factory, no additional refrigeration setup is required.

Electrical Connection

| WARNING
---|---

Some procedures in this manual require the power to the equipment to be turned off and isolated. Turn the power OFF at the power point and unplug the power supply lead by the plug body. If the power point is not readily accessible turn the equipment off at the isolation switch or the circuit breaker in the switchboard.
Attach a yellow “CAUTION-DO-NOT OPERATE” tag. This must be performed where relevant unless the procedures specify otherwise.
FAILURE TO DO SO MAY RESULT IN ELECTRIC SHOCK.

Single Phase Units:
Supplied and fitted with an appropriately rated plug and lead, 10A plug.
When connecting and disconnecting the appliance, pull on the plug, not on the cable.
Notes:
If the supply cord is damaged, it must be replaced by the manufacture, its service agent, or similarly qualified persons in order to avoid a hazard. Please contact Nuline for parts and we will advise how to do this in order to avoid any electrical hazard.
The power cable should be dry and isolated from moisture and water.

Plumbing
No additional drainage or plumbing is required.

Shelves

Adjustable Shelf Installation

Fully open the door.
Lift up the shelf so that it is fully off the shelf support clips to remove the shelf.
Gently pull up to remove the shelf support clips
Push the shelf support clips down into the space on the rails at the level that you desire.
Ensure that all four shelf support clips are at the same level.
Carefully lower the shelf inside the cabinet on top of the shelf support clips
Ensure that the shelf is fully inside the cabinet before loading and closing the door

When loading the shelves with product, care should be taken to ensure that the product is loaded evenly to allow for proper air circulation around all products.
Note: Do not use pilers when installing the shelf support clips
Loading Restrictions

There should NOT be any overhang of products on the shelves.
Shelves are only designed to hold one layer of product. Overloading can break / damage the shelves and prevent proper air flow.
Remove some products if the shelves are flexing or bending.
Shelves should be adjusted to allow air space around all the product to ensure proper air flow and even refrigeration to ensure efficient operation of the cabinet.

Locking

This cabinet comes standard with a key door lock. It is recommended not to keep the key in the lock during normal use. This will prevent the bending or breaking of the key inside the lock. If the key is broken inside the lock, the lock will have to be replaced.
Keeping the key removed from the lock will also prevent the lock from accidentally locking when the door is open. Locking when the door is open could prevent the door from closing properly, resulting in the cabinet temperature to rise.

Remote Alarm Contact

A Remote Alarm Contact is optional on this cabinet, if it is required it should have been requested at the time of ordering the cabinet to ensure that it can be installed during manufacturing.
A voltage free Remote Alarm Contact is used to connect to a Building Management System (BMS).
For installation simply connects the network cable from the BMS into the cabinet. We do not provide the network cable.
Please see below for an example of where the Remote alarm Contact can be found.

Temperature Probes

This cabinet is equipped with a temperature probe inside the unit that monitors the temperature inside the cabinet. This probe also controls the temperature alarms.
To monitor the temperature in various areas of the interior of the cabinet, external probes can be installed through the port entry.

Port Entry

To monitor the temperature in various areas of the interior of the cabinet, external probes can be installed through the port entry. A port entry is optional on this cabinet, if it is required it should have been requested at the time of ordering the cabinet to ensure that a port entry can be installed during manufacturing.
Installation of External Probes

Never install probes through the door as this will prevent the door from closing properly, thus preventing a correct seal from forming and from preventing the cabinet from maintaining the correct temperature. This will damage the door gasket which will prevent a correct seal from forming.
Nuline Refrigeration will not be held liable for the damage caused by the incorrect installation of external probes out of the door.
