SERVICING, MAINTENANCE AND REFRIGERANT HANDLING

1. R290 is classified as flammable refrigerant of Class A3 according to ANSI/ASHRAE. It is a highly flammable and very easy to ignite. It can burn with explosive impacts.

2. R290 in contact with air can cause a risk of fire or explosion in presence of open flames or sparks generated by electrical equipment.

3. R290 (Propane) has no odour. Take extra cautions if a leak is suspected i.e. quarantine the cabinet and call for a qualified refrigeration service technician to attend.

4. Servicing can be only performed by qualified personnel holding a valid certificate and competence to work on and break into a R290 refrigeration circuit safely.

5. Service intervention must be carried out considering the mentioned above risk: do not use electric tools and open flames.

6. Components which require substitution: – only use original spare parts for they have been specifically approved for use with R290 (Propane) refrigerant.

7. The refrigerant circuit is hermetically sealed (closed loop) therefore refrigerant filling, draining or substitution of some components is not possible without breaking the vacuum.
   In such a case:
   i. the substitution cannot be performed indoors at the customer’s premises.
   ii. the cabinet should be moved to a controlled workshop environment suitable for the type of repair where work can be conducted safely.
   iii. In any case, work in confined spaces must be avoided. Work area can be in the open or, alternatively, must be properly ventilated. Ventilation should be able to safely disperse any released refrigerant and expel it safely externally to the atmosphere.

8. While working on cabinet with R290 during which the refrigerant can be possibly released to the surrounding space, all possible ignition sources, including cigarette smoking, must be at least 10 metres away from the place of  installation, maintenance or disposal.

9. In case hot work is required (welding, brazing) best practice must always be applied. This should require the following procedure to avoid risk of fire or explosion.
   i. remove refrigerant safely
   ii. purge the circuit (with inert gas)
   iii. evacuate
   iv. purge again with inert gas
   v. open the circuit by cutting (or brazing)
   vi. Operator must be properly skilled and authorized to perform hot works on systems working with flammable refrigerants.

10. In order to reduce flammability hazards the installation of this appliance must only be carried out by a suitably qualified person.

11. Always use appropriate Personal Protection (PPE) i.e. gloves, safety glasses, boots or shoes, long pants, long-sleeve shirt, etc.

12. Take extra caution with Anti-static protection when undertaking any electrical and/or controller work.

Receiving Cabinets
Cabinets will always be dispatched in good condition. Always inspect the cabinet and packaged accessories for damage. Note any damage on the carrier’s consignment note prior to signing.

Prior to installation Cabinets must be stored protected from the weather and at temperatures and humidity’s within 0°C ~ +45°CDB / 30% ~ 80%RH.

NOTE: – Please provide a photographic record of any damage found along with the cabinet serial number and a brief description of the damage.
NOTE: – Any shortages will follow the same procedure as concealed damage.

A check should also be made to ensure that all loose parts listed on the outside packaging are present and undamaged.

Moving Cabinets to Installed Position

****To ensure any risk of damage to cabinets while moving to their installed location is minimised, it is strongly recommended that the following instructions are followed.

Equipment Required:
1 x Suitably sized Pallet Truck or Fork hoist.
NOTE: – the SGN141S-1 cabinet is fitted with castors for final positioning, please take care as wheels can be difficult to steer and/or may run freely on slight gradients. This is a minimum 2person task.
Once cabinets have been moved into the store with the shipping pallets** still attached, the following methods should be  used to move cabinets to their final installed position:

1. Carefully lift the cabinet off the pallet with a fork hoist or pallet truck, taking care to position the forks in the centre of the cabinet and directly under the skid rails. Test for stability / centre-of-gravity balance before making final  movements.
2. Ensure the mounting feet bolts are screwed-up, such that the wheels can be utilised when cabinet is lowered to the floor. Gently lower the cabinet on to the shop floor.
3. Ensure the floor where the cabinet is to be manoeuvred, is swept and free from debris, as this could otherwise result in a roller wheel coming to an abrupt stop and destabilise the cabinet.
4. Once cabinet is in the required position, screw all four (4) feet bolts down into position evenly such that all four (4) feet bolts take the full load of the cabinet and the roller wheels have between 5mm ~ 10mm free space from the  floor.
5. Ensure the cabinet is securely positioned and levelled via a spirit / laser / or theodolite level.
6. These Cabinets draw store ambient air in through the Condenser coil located at the bottom of the cabinet. Do not block either air entry or exit areas of the cabinet. NOTE: the top air exit should have at least a 1.0m clear area and height above the cabinet  to allow correct airflow and dissipation.
7. If the cabinet has been tilted during positioning/installation, wait at least three (3) hours before starting in order to allow any potential oil displacement to settle.

**Timber (pallet only) and plywood (box only) used for shipping materials and they are heat treated (pallet only) and can be recycled

MAINTENANCE

**To ensure this range of cabinets maintain food products at the correct temperature, the following information should be followed.
Starting up (by appropriately qualified person)
Check power supply is ready and correct Voltage (230V ~ 240V) and all fans are clear of packaging and all shelves and panels are correctly fitted.
Turn cabinet power on.
Check that all fans and lights are working correctly. Cabinet refrigeration system will take a few minutes to commence cooling, observe operation and ensure cabinet pulls temperature down and cycles between its cut-out and cut- in temperatures. Cabinet  temperature is displayed in the lower section via an LED display from the cabinet’s microprocessor controller.
Allow the Cabinet to operate for minimum 3 hours before loading with product.
WARNING: – Keep the air vents (front and top) clear of any obstructions.
Load Limits
These cabinets have a load limit that ensures food products stored within these load limits are properly refrigerated. Food products stored outside these load limits may not be properly refrigerated and disturb the airflow with the result that cabinet performance is  compromised, and food products may be damaged. NOTE: – merchandise should be pre-chilled to below +5°C prior to placement in the cabinet.
Internal Fittings and Accessories**
Only fittings and accessories approved by the manufacturer should be used. Any other additions the cabinet to not work in its intended fashion.

Cleaning
To maximize efficiency and durability, it is suggested that your effect an appropriate cleaning and maintenance program.
Wear appropriate PPE when cleaning or maintaining cabinet to prevent scratches or splashes (i.e. gloves, safety glasses, etc.).
Galvanized steel (painted) is used inside the cabinet and it is not rustproof, particularly in the harsh environment of Food Display cabinets. Chlorine and bromine, commonly used for sanitization are highly caustic chemicals for stainless steel, in heat and humidity,  the corrosiveness of these chemicals is enhanced.
Regular cleaning is the best way to prevent corrosion and add to the service life for your stainless steel product.
The goal of your cleaning and maintenance program should be to keep the stainlesssteel’s protective chromium oxide layer intact. This is what prevents corrosion.

For internal cleaning use:

• Warm water (Less than 55°C)
• Water based cleaning solutions
• Soft cloths

Do not use:

• Abrasive products
• Solvent based products
• Steam or high-pressure water systems

When cleaning:

• Check drain trap is clear of obstructions.
• Do not flood the base of the cabinet or well area as water may overflow the small volume water tray in the bottom section of the cabinet onto the floor creating a slipping hazard.
  The SGN141-S is a self-contained cabinet with a limited water dissipator tray, when cleaning use minimal water (maximum 1 litres) and carefully observe the water tray in the lower section of the cabinet to prevent excessive water use/overflow.

Cleaning Acrylic/Perspex (front display)
Clean with a non-abrasive soap (or detergent) and luke-warm water, using a soft grit free cloth, sponge or chamois.
Wipe the Acrylic/Perspex dry with a clean damp chamois or clean soft cloth such as a cotton flannel.
Do not use hard, rough cloths or paper towels, as they will scratch the acrylic
Waxing Acrylic/Perspex (front display)
Once the Acrylic/Perspex is clean, minor scratches can be removed using a good grade commercial wax. The wax should be applied in a thin coat and brought to a high polish by rubbing lightly with a dry clean soft cloth, such as a cotton flannel. Do not rub  excessively as this may build up a charge that will attract dust to the surface. Blotting with a clean damp cloth is recommended to remove charge.
Cleaning Glass Surfaces (ends)

• Use Domestic glass cleaning fluid, Ammonia based glass cleaner may be used.
• Spray fluid onto a cloth then wipe the glass in a circular motion.

Painted Surfaces

• Use a soft cloth.
• Do not use solvent based cleaning products.
• Always rinse internal surfaces with warm water and allow to dry before re-starting the refrigeration system.

Evaporator Coil

• Never use sharp objects around evaporator coils to de-ice them.
• If the coil has solid ice formed. This indicates the refrigeration and/or defrost cycle are not set correctly. Contact your refrigeration service provider to investigate.
• Use warm water to de-ice coil if required, but not so much as to flood the well/condensate tray in the lower section of the cabinet.
• Use a soft brush or vacuum brush to clean coil. Use PPE (gloves, safety glasses, etc.)
• Do not bend fins.

Condenser Coil

• Never use sharp objects around condenser coil.
• Clean the condenser coil with a soft brush or a vacuum cleaner. The dust and fluff obstruct good air circulation and reduces cabinet performance and increases energy consumption.
