INSTALLATION, OPERATION AND CARE OF OV450 & OV452 SERIES DECK OVENS
SAVE THESE INSTRUCTIONS

GENERAL

The OV450 & OV452 Series Deck Ovens (Fig. 1) are designed and suited for your baking needs. The deck ovens are available in three sizes: OV450N, OV450W, and OV452N. The OV450N and OV450W single baking chamber decks are confi gurable from 1 to 4 units high. The OV452N double baking chamber deck is confi gurable in either 1 to 3 units high. They are produced with quality workmanship and material. Proper installation, usage and maintenance of the ovens will result in years of satisfactory performance. It is suggested that you thoroughly read this manual and carefully follow the instructions provided.

INSTALLATION

The OV450 & OV452 Series Deck Ovens require some assembly and must be installed by authorized Bakery Systems trained service technicians.

UNPACKING
This oven was inspected before leaving the factory. The transportation company assumes full responsibility for safe delivery upon acceptance of the shipment. Immediately after receiving the oven, check for possible shipping damage. If the oven is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.
Carefully unpack the oven and place in a work-accessible area as near to its fi nal installed position as possible. Verify all packaging material has been removed from the interior of each deck. Remove protective covering from exterior surfaces prior to placing oven in its fi nal location.
Prior to installation, verify that the electrical and the water service agrees with the specifi cations on the oven data plate and in this manual.

INSTALLATION CODES AND STANDARDS
In the United States, the Deck Oven must be installed in accordance with:

1. State and local codes.
2. National Electrical Code (ANSI/NFPA No.70, latest edition) available from the National Fire Protection
   Association, Batterymarch Park, Quincy, MA 02269.

In Canada, the Deck Oven must be installed in accordance with:

1. Local codes.
2. Canadian Electrical Code (CSA C22.2 No.3, latest edition) available from the Canadian Standards Association, 5060 Spectrum Way, Mississauga, Ontario, Canada L4W 5N6.

WATER REQUIREMENTS
NOTICE As with all steam related products, water filtration and regular filter replacements, coupled with routine deliming, are required. Your local Service office can recommend a water treatment system to meet the needs of your local water conditions. Contact your local Service representative for water treatment offerings.
Proper water quality can improve the taste of the food prepared in the oven, reduce liming and extend equipment life. Local water conditions vary from one location to another. The recommended proper water treatment for effective and efficient use of this equipment will also vary depending on the local water conditions. Ask your municipal water supplier for details about your local water supply prior to installation.

Dynamic
Water
Pressure| Hardness| Silica| Total Chloride| pH Range| Chlorine & 
Chloramine| Alkalinity| TDS| Undissolved Solids
---|---|---|---|---|---|---|---|---
30-80 PSIG| 2-4 grains| < 13 ppm| < 30 ppm| 07-Aug| 0 ppm| < 20 ppm| < 60 ppm| < 5 microns

Water hardness above 4.0 grains per gallon should be treated by a water conditioner (water softener and/ or in-line water treatment). Water hardness below 2.0 grains per gallon may also require a water treatment system to reduce potential corrosion. Water treatment has been shown to reduce costs associated with machine cleaning, reduce deliming and reduce corrosion of metallic surfaces.

LOCATION
Allow space for operating the oven. The oven requires approximately 3″ from the back of the oven for electrical and plumbing connections. Do not obstruct the ventilation ports on the sides or back of the oven. To prevent heat accumulation, 1″ clearance is required from any wall. The oven must be installed on an approved stand. Minimum clearance of 60″ must be provided in front of the oven so the oven can be pulled forward for servicing.

PLUMBING CONNECTIONS
Water and waste piping and connections shall comply with the International Plumbing Code 2003, International Code Council (ICC), or to the Uniform Plumbing Code 2003, International Association of Plumbing and Mechanical Offi cials (IAPMO).
WARNING Plumbing connections must comply with applicable sanitary, safety and plumbing codes and provide adequate backfl ow protection to comply with applicable federal, state and local codes.
Connect the cold water supply to the 3 /8″ NPT connection located at the rear of the oven. Water supply should have a pressure of 30 to 80 psi. The oven is supplied with a fl ow regulator which must be installed.

DRAIN CONNECTIONS
NOTICE In order to avoid any back pressure in the oven, do not connect solidly to any drain. Drain connections from each deck to the collector box must be high temperature hose. Connect the 1/2″ drain connection from each deck to the collector box on the deck oven stand. Route the drain line from the collector box to a fl oor drain. An air gap is provided by the collector box. No air gap required at fl oor drain.

ELECTRICAL CONNECTIONS
NOTE: The oven must be installed with the provided lanyard securely attached to one deck and to the wall. Verify that all connections are long enough so that the oven can be pulled forward to the extent of the lanyard without straining any connections.
WARNING Electrical and grounding connections must comply with the applicable portions of the National Electrical Code and/or other local electrical codes.
WARNING Disconnect the electrical power to the unit and follow lockout / tagout procedures.

CLEANING

WARNING Disconnect the electrical power to the machine and follow lockout / tagout procedures.
WARNING The oven and its parts are hot. Use care when operating, servicing or cleaning the oven.

DAILY CLEANING

• Always allow the oven to cool before cleaning. Never attempt to cool the oven down with water. Sudden temperature changes could damage the glass or baking stones.
• Use care when cleaning around sensitive interior parts, such as probes and sensors.
• Sweep loose particles off the baking stones. Gently scrape off any hardened material on baking stone. Do not use a wire brush or metal scrapper.
• Using a clean cloth moistened in warm, soapy water, wash the interior of the oven cavity. Rinse with rag moistened with clean water and dry with a clean cloth. Be careful not to drip onto the stone. This could cause the stone to crack when heated back up.
• Clean the outside daily with a clean, damp cloth.
• Do not use cleaners containing grit, abrasive materials, bleach, harsh chemicals or chlorinated cleaners. Do not use steel wool on stainless steel surfaces. Never spray down the oven with water, steam or power wash.
• Be cautious with new or improved cleaning formulas; use only after being well tested in an inconspicuous place.

CLEANING THE DOOR GLASS
