3 INSTALLATION AND POSITIONING

INSTALLATION and POSITIONING

Bring the glasswasher to the installation site, remove the packaging and check the appliance and components for damage; any damage found must be reported to the transporter in writing. The packaging components (plastic bags, expanded polystyrene, nails, etc.) must not be left within reach of children and pets since they are potentially dangerous. All packaging materials used are environment-friendly. They can be kept without constituting any hazard, or may be disposed of at a specialist waste disposal centre. The plastic components suitable for recycling are marked as follows: PE polyethylene: external packaging film, bag containing the instructions, protective bags. PP polypropylene: straps. PS expanded polystyrene: corner guards, top of packaging.

CWG 520-530

Water supply and drain connection

The water pipelines and electricity supply cable lead out of the bottom right-hand corner of the appliance. Connect the water intake hose to a connector with ¾” threaded fitting, fitting the filter A provided (in models with acquastop, the filter and ring-nut form a single unit). The connection to the water mains must only be made with new hoses; the use of old or worn hoses is not permitted.

Caution: the indoor system and premises in which equipment for institutions is installed must comply with the relevant regulations.

The manufacturer declines all liability for direct or indirect injury or damage deriving from failure to comply with these regulations. Before installation, check that there are no objects or materials in the vicinity which may be damaged by steam or splashes of washing solution, or that any such items are suitably protected. Place the glasswasher in the chosen point and remove the protective film. Level the glasswasher (with the aid of a spirit level) on its adjustable feet to ensure that it is stable; all other mounting solutions must be approved by the manufacturer.

Wooden and cardboard components can be disposed of in accordance with the relevant regulations. When the product is decommissioned it must not be dumped in the environment; it must be disposed of in accordance with the relevant regulations. All metal parts are in stainless steel and can be removed. The plastic parts are marked with the symbol identifying the material used and must be disposed of in accordance with the relevant regulations. When the product is decommissioned it must not be dumped in the environment; it must be disposed of in accordance with the relevant regulations. All metal parts are in stainless steel and can be removed.

POSITIONING:

4 INSTRUCTIONS FOR TECHNICAL STAFF

4.1 lumbing hookup

FOR MODELS WITH A WATER SOFTENER

AN ‘APPROVED’ DOUBLE CHECK VALVE OR SOME OTHER NO LESS EFFECTIVE DEVICE PROVIDING BACKFLOW PREVENTION PROTECTION TO AT LEAST FLUID CATEGORY TWO SHALL BE FITTED AT THE POINT OF CONNECTION BETWEEN THE WATER SUPPLY AND THE FITTING OR APPLIANCE.

FOR MODELS WITHOUT A WATER SOFTENER

AN ‘APPROVED’ SINGLE CHECK VALVE OR SOME OTHER NO LESS EFFECTIVE DEVICE PROVIDING BACKFLOW PREVENTION PROTECTION TO AT LEAST FLUID CATEGORY TWO SHALL BE FITTED AT THE POINT OF CONNECTION BETWEEN THE WATER SUPPLY AND THE FITTING OR APPLIANCE. The dynamic water supply pressure must be between 1 and 6 bar; if it is higher a pressure reducer must be installed. It is essential to fit a main stop tap on the water intake deliver pipeline; the tap must be accessible after installation of the appliance, so do not install it behind the warewasher. The stated cycle duration applies to appliances supplied with hot water >50°C<60°C If the warewasher is supplied with cold water, the cycle duration might increase depending on the intake water temperature. The warewasher is fitted with a drain pump and can operate with drain connections

CWG 520-530

Caution: make sure that the intake and drain hoses are not bent, constricted or crushed after installation.

The glasswasher and any additional equipment must be connected to the electrical system by authorised, skilled staff, in accordance with the relevant regulations; also

comply with the technical instructions for the connection. The total rated power is stated on the appliance’s technical data plate. The electrical protection devices fitted for the glasswasher must serve this appliance only. The user must have a master switch and a differential safety breaker, with rating

suitable for the appliance’s characteristics, installed on the electricity supply line in accordance with the relevant regulations.

These switches must be installed close to the glasswasher, be easily accessible after installation, and provide complete disconnection from the electrical mains in overvoltage class III conditions.

Warning !!! The glasswasher is always powered up unless the master switch is turned off.

Connect the appliance to the user’s earth system. The terminal for the connection is

in the bottom right-hand corner of the appliance. The earth wire (PE) is yellow-green in colour, the neutral wire (N) is blue and the live wires (L1, L2, L3) are black, grey and brown. In the event of single-phase connection (230V-1N~), the connection to the electrical

mains must be made using a cable with plug compliant with the relevant regulations.

THE POWER SUPPLY CABLE, AS PROVIDED, MUST BE REPLACED BY THE MANUFACTURER OR AN AUTHORIZED SERVICE CENTER IN COMPLIANCE WITH THE SPECIFICATIONS PROVIDED ON ELECTRICAL DIAGRAM SUPPLIED IN THE MACHINE IN ORDER TO PREVENT ALL RISKS.

on the floor or wall. Refer to the connection diagram for the maximum permitted height of wall drains – (see TECHNICAL DATA)

When installing the drain hose to a siphon with valve, the maximum height of the drain outlet is reduced to 600 mm.

4.2 Electrical connection

CWG 520-530

Before inserting the hoses into the containers, fit the weights (needed to ensure that they always draw in liquid from the bottoms of the containers) and the filters onto their ends as shown. If the detergent dispenser is not factory-fitted, it can be retrofitted after ordering the relative kit.

The quantity of lime in the water (which indicates its hardness) causes whitish marks on dry dishes and dishes also tend to lose their shine over time. The glasswasher is equipped with an automatic water softener which removes the substances that cause hardness from the water with the aid of regenerating salt.

The first time the glasswasher is used, a litre of water must be poured into the tank with the salt. Whenever the tank is filled, always take care to ensure that the cap is firmly closed. The mixture of water and detergent must not get into the salt tank, as this would impair operation of the regeneration system. In this case warranty cover will be forfeited.

5 FIRST START-UP

First start-up

The electrical protection system must undergo a functional test before the appliance is put into operation. The appliance must be installed and/or inspected by qualified staff, who will start it up for the first time and provide the relevant operating instructions.

Preparing for use (important)

The rinse aid dispenser is fitted on all models, the detergent dispenser only on some. If both dispensers are present put the external detergent and rinse aid containers in place and insert the respective intake hoses on the rear of the appliance into them. Red hose: detergent blue hose: rinse aid NOTE: It takes about 10-15 wash cycles before they arrive in detergent and rinse tank and boiler

As an alternative an external dispenser can be fitted, making the electrical connection by means of an H05 RN-F 2x0.5 mm electrical cable, which can be laid along the route shown in the TECHNICAL DATA diagram and connected as shown in the wiring diagram supplied with the glasswasher. The dispenser must operate on 230V/50 Hz with maximum power absorption of 15 W. Connect to the detergent dispenser outside the glasswasher using the red hose mentioned above.
