1.0 INTRODUCTION
The electric modular Deck Oven is an easy to use practical, good-looking oven,
giving an excellent heat recovery rate and an even bake across a wide range of
bread and confectionery products.
Good looking and totally reliable
Conceived with the no nonsense requirements of both the independent and in-store
baker in mind, and designed to visually please as well as give reliable service for
many years. This oven will more than satisfy the most discerning customer.
Top quality specification
The external and internal contact surfaces are stainless steel.
Each modular deck is fitted with durable reinforced deck tiles, and an increase in
high-grade insulation and high temperature ceramic sealant, makes the oven more
efficient.
The oven comes with a patented integral steaming system, which reduces energy
consumption and the overall size of the oven (no drain required). The system
produces real steam with the advantages of spray steam. Pre-steam is also available
to reduce the affects of long loading times.
No drainage is required.
Supplied with an LED screen. All programmable parameters have separate indicators
for easy programming and extra bake time, if required.
An energy saving 7-day timer is also standard.
The simplified electrical circuits aid reliability with overheat protection (on controllers
and oven) to ensure long life of controllers, all housed in splash-proof electrical
enclosures.
The lights are low voltage, sealed from the chamber and easily accessed from
outside the oven.
An “i” button can be used to upgrade firmware without the need of dismantling the
panels.
Fitted with a choice of hinged easy to clean double glazed doors (using low energy-
loss reflective glass for high visibility) or metal doors, means low energy consumption
and the high kW rating gives good recovery.
(0-100% heating available both top and bottom)

4.0 SAFETY
All maintenance must be made with the oven disconnected from the
power supply and then only by fully trained authorized persons.
Check all cover panels, and any pipefittings are securely positioned.
Check oven door handles are not damaged.
Do not operate a deck's steaming system with oven door open.
Always use oven gloves when loading or unloading the oven.
When products are removed from the oven, ensure:
(a) Tins are knocked out and stored directly onto a tin storage trolley or rack
(Do not leave hot tins on the floor or on tables).
(b)Trays are put into a rack and the rack is wheeled to a safe cooling area.
Do not store items on top of the oven.
Do not store items behind the oven.
Beware of hot surfaces. Do not touch oven front or door with bare skin.
All operatives must be fully trained
People undergoing training must be under direct supervision
The oven should only be used for baking bread, pastries and cakes (for other
products please contact your oven supplier)
No unauthorized modifications should be made to the oven.
Do not walk on the roof of the oven
DISPOSAL
Care should be taken when the oven comes to the end of its working life. All
parts should be disposed of in the appropriate place, either recycling or other
means as the law permits at the time.
NOTE: BAKERY STAFF MUST NOT UNDER ANY CIRCUMSTANCES REMOVE
PANELS TO ACCESS ANY PART OF THE DECK OVEN.
Panels should only be removed by a Mono maintenance engineer (or other fully
trained maintenance contractor) for repairs or maintenance, after isolating oven
from power supply.
The Bakery Manager or the Bakery Supervisor must carry out the above daily safety checks

5.0 INSTALLATION
GENERAL
A hard smooth level floor is recommended on which to position the oven and
access for maintenance should be considered.
The oven is not designed to be ” built in” so sufficient clearance must be left in
front of the access panels (right hand side) to allow for servicing.
If not chosen as an oven option, it is recommended that an extraction hood be
placed above the oven to disperse excess steam and heat, which could have
an adverse effect on the bakery ceiling and ambient temperature.
A wall isolator must be available in order to completely isolate the oven.
THIS ISOLATOR MUST BE CLEARLY ACCESSIBLE TO THE OVEN OPERATOR
A chain retainer should be fitted, that is shorter than the power cables, to
protect them from strain if the oven is moved. (Fit to the wall or floor and the
base, using hole provided in castor fixing corner plates).
Installation must be made by a trained authorized engineer and all utilities
must conform to all local regulations.
The oven must be “run in” as stated in the initial start up instructions.

WATER SUPPLY REQUIREMENTS
The set up procedure on the next page must be followed to
allow the steaming system to function correctly
All ovens with steam require a ½” NPT hot or cold water supply at a pressure
of 2 - 3 bar (29 –44 psi). Located approximately 250mm from the right and
100mm from the top of the stand when facing the front of the oven.
Only one water supply is required per oven. The connections should comply
with local water regulations. A manifold supplies all decks from one connection
point.
For proper operation of the steam system it is recommended that the water
supply follows the following specifications:
Hardness 2-4 grains per gallon
PH range 7.0 to 8.0
Chloride concentration 0 –30 ppm
Consult your water treatment company for proper water filtration system
information.
No drain is required for this oven.
A non-return check-valve is supplied fitted to the water inlet manifold.

WATER SYSTEM SETUP PROCEDURE
It is imperative that the water delivery to the deck oven is checked for the
steam system to operate correctly
1. Flush out the main feed pipe to be used, until water runs clear and free from debris.
2. Connect main feed to oven.
3. Connect flexible hoses to each deck.
4. Place a container under the test valve.
5. Slowly open test valve fully and with the water flowing check the regulator is set to
0.75 bar. If not adjust using the screw above the valve.
Never use the oven above this setting
6. When the pressure has stabilised shut the test valve.
REPEAT 4,5 AND 6 AT THE END OF INSTALLATION.
NOTE. DYNAMIC PRESSURE, NOT STATIC, IS BEING MEASURED.

Exhaust Connections (IF CANOPY FITTED)
Ideally an exhaust duct should rise 2 metres above the bakery roof protected
from wind and birds by a duct protector.
It should be of a suitable material to take the high temperatures and humidity
expected.
It should be flexible and easily removable at the oven connection point.
This allows the oven to be moved for cleaning when required.

7.0 CLEANING
DAILY CLEANING INSTRUCTIONS
ISOLATE OVEN FROM MAINS SUPPLY BEFORE CLEANING.
After the oven has been allowed to cool, (this could take several hours),
sweep any debris out.
Use a vacuum cleaner with metal attachments (able to take heat) if available.
Brush down and wipe oven front, back and sides with a damp cloth.
Spot clean with a damp cloth, which has been soaked in a solution of mild
detergent, and hot water, paying particular attention to ensure excess water is
not applied around the area of the electrical panels.
NOTE: TAKE CARE WATER DOES NOT ENTER CONTROL PANEL
MOUNTING OR ROOF MOUNTED FAN.
WEEKLY CLEANING INSTRUCTIONS
ISOLATE OVEN FROM MAINS SUPPLY BEFORE CLEANING.
Complete daily cleaning as above.
Scrub oven wheels with a mild detergent and hot water using nylon cleaning
brush (excess water will rust metal).
Ensure the oven roof area is clear of debris and dust build up.
(DO NOT STAND ON THE OVEN ROOF)
