•The appliance must be electrically grounded in accordance with local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.2, as applicable.
The grounding conductor must therefore be connected to the terminal marked Gon the connection terminal board. The appliance must also be connected to an earth grounding system.
This connection is made using the stop screw marked E located on the outside of the appliance near the power cable inlet.
The grounding wire must have a minimum
RATING PLATE
GROUNDING INSTRUCTIONS :
This appliance must be connected to a grounded, metallic, permanent wiring system, or an equipment grounding conductor should be run with the circuit conductors and connected to the equipment grounding terminal or lead on the appliance.
3.1 POWER CABLE INSTALLATION
To connect the power cable to the appliance, proceed as follows:
Model 6 - 10 - 20 GN
•Remove the left side panel.
•Connect the cable to the terminal block as shown in the wiring diagram attached to the appliance, and secure it with the special cable gland.
The manufacturer declines any liability if the safety regula- tions are not respected.
The manufacturer requires when stacking units each appliance have its own branch circuit protection. An
4. WATER CONNECTION
(See the installation diagrams at the beginning of this handbook)
This equipment is to be installed to comply with the applicable Federal, State, Local plumbing codes, or the Basic Plumbing Code of the Building Officials and Code Administrators International Inc. (BOCA) and Food Service Sanitation Manual of the Food and Drug Administration (FDA).
The oven has two separate inlets (“B” and “N”) for the supply water.
The supply pipes of both inlets must be equipped with a me- chanical filter and shutoff cock. Before installing the filters, it is advisable to let a certain amount of water flow in order to clean the pipe of any solid particles.
4.1 SUPPLY WATER CHARACTERISTICS
4.1.1 WATER INLET “N”.
Important (LEVEL A ONLY)
The water supply pipe must have an inside diameter of at least 20 mm and be free of elbow unions.
The discharge steam condensation system can be fed with cold water suitable for human consumption, having the following characteristics:
-total hardness not exceeding 400ppm (40°fH); in LEVEL A ovens equipped with CLEANING SYSTEM it is advisable to use water of hardness not exceeding 5° French; for that purpose, a water softener with automatic regeneration for installing on inlet line “N” is supplied as an accessory by request.
-pressure between 22 to 36 psi
Note:
To check correct water installation, make sure the rotating wash arm (CLEANING SYSTEM) does not turn below 100 rpm (120 max).
4.1.2WATER INLET “B”. (With feed pipe supplied)
The inlet for steam production must be fed with water suitable for human consumption, having specific characteristics:
- total hardness between 5 - 50ppm (0.5 - 5 °fH) French for reducing scaling inside the steam generator.
For that purpose, a water softener with automatic regeneration for installing on inlet line “B” is supplied as an accessory by re- quest;
it has a kit for sterilizing the resins (by further request).
- pressure between 22 to 36 psi
- chlorine concentration (Cl
- pH higher than 7.
For that purpose, a special filtering unit for installing on inlet line “B” is supplied as an accessory by request. The purpose of this unit is to reduce the water hardness to optimum values (below 50ppm "5 °fH") (optimum value), and therefore also serving as a water softener.
- electric conductivity between 50 and 2000 µS/cm (68°F) (20°C).
Important: The use of water treatment systems utilizing methods different from those indicated by the manufacturer of the equipment is not allowed and will completely invalidate the warranty.
Likewise, dispensers of substances for preventing scale in the pipes (e.g. polyphosphate dispensers) must not be used because they can compromise correct machine operation.
