INTRODUCTION
THIS IS HOW YOUR CONVECTION OVEN WORKS
Convection oven RV1 relies on fans to force air to circulate between electrical heating
elements and products continuously, in this way heat is transferred to products more
efficiently than baking in still air in conventional ovens, that is why convection ovens
can operate at a lower temperature than conventional ovens and yet bake products
more quickly. RV1 convection oven is electric heated.
Steam system is constructed of pipes and nozzles near the fan, steam is generated
as water sprays onto hot surface around heating elements. For some kinds of bread,
sufficient steam is necessary to get right surface structure.
Hood with air extractor located over the oven door can trap the steam and cooking
smoke coming from the oven chamber and expel them to the outside through exhaust
duct.

INSTALLATION
PRE-INSTALLATION
CAUTION: Do not allow any part of your body to be under the unit during the lifting
process. Keep everyone clear from the unit if it should fall.
CAUTION: To reduce the risk of fire, the unit is to be mounted on floors of noncombustible construction with non-combustible surface finish, keep area around the
unit clear of combustibles.
CAUTION: Allow the unit to run only in proper work area with adequate light and
space, do not obstruct any ventilation opening on the unit.
─ Retain all shipping materials until you are certain that the oven has not been
damaged (either externally or internally) during shipment. It is solely customer’s
responsibility to report any shipping damage to the freight company.
─ Check the area where the oven is to be installed for the following:
a) The ground must be firm, level and fire-proof, make sure there are no
obstacles and debris under the floor of the oven.
b) The area must be drafty and clear of all combustibles, make sure all the
ventilation openings on the oven are unobstructed.
c) The clearance above the oven should allow the installation and maintenance
of the assemblies on top of the oven, a minimum clearance of 0.5m at the
sides and back of the oven is required.
d) The installation location must allow adequate clearance for servicing and for
the proper operation of the loading door.
e) It is necessary to prepare the room for all connections to the oven: electricity
and water shutoffs are required within a reasonable distance to the oven,
clear access to the exterior of the room for exhaust duct is also needed.
─ Unloading the oven shall be done with safety in mind. The use of proper unloading
equipment is strongly recommended. When using a forklift, make sure the lifting
capacity of the forklift is adequate and the forks do not damage any parts of the
oven. Prior to unpacking, move the oven as near to its intended location as
possible. Existing packaging will help protect the oven from physical damages.
CONNECTION
CAUTION: Installation of the unit must be done by personnel qualified to work with
electricity and plumbing and must comply with all applicable nation and local codes.
CAUTION: This unit is equipped with a five-core cable for your protection against
shock hazard and should be connected directly into a properly grounded circuit
breaker.
CAUTION: It is imperative that the oven is connected to the chimney according to
the regulations to vent the products of combustion.
─
Connect the 380V three phase power supply to the oven. Consult the data plate
for specific current and voltage ratings. Be sure that the wire used is in
compliance with local requirements. Grounding is vital to avoid unexpected
damage and accident, make sure the oven is well grounded.
─
Connect water supply to the oven at the water solenoid valve located in the
control cabinet. Water supply must be between 20 and 80 PSI at all times with a
water flow of 30 liters per minute while steaming. Steam is only used 10 seconds
every 1/2 hour so water consumption will be very low. Provide a water shut-off
valve near the oven for servicing. Water softening device is necessary if the tap
water is too hard.
─
It is the customer’s responsibility to supply all materials and labor required to
adequately vent their ovens. Φ80mm metal bellows is needed to connect the hood
with opening on the wall or roof.
START-UP
CAUTION: When the loading door is opened, hot air and steam are released from
the oven interior. To avoid burns, open door slowly and keep your face and hands
clear of the opening. All interior surfaces are extremely hot, do not touch anything
without oven mitts.
CAUTION: Always keep hands or body parts away from moving parts.
─
Remove all protective coatings from the oven surface, inside and out.
─
Turn on the water supplies to the oven. Check for leaks. Repair any leaks before
proceeding.
─
Conform that all electrical connections are proper and all covers are in place.
Confirm that the oven is properly grounded.
─
Turn on electrical power to the oven. Turn on all circuit breakers located in the
control cabinet.
─
Turn on the main switch of the control panel, the control display should light up.
─
Close the loading door and check the direction of rotation of the circulation fan
motor, the top and bottom circulation fan motors should rotate in the same
direction whereas the middle two circulation fan motors should rotate in the
opposite direction.
─
Heat the oven to 250°C. Refer to the operation section of this manual for
operating instructions. During the first few hours of heating, you may notice a
small amount of smoke coming off of the oven, and a faint odor from the smoke,
this is normal for a new oven and will disappear after the first few hours of use.
─
During operation, check the oven for gas leaks, excessive smoke, and vibration.
Report any abnormal condition to our after-sale service department and never
operate this equipment before receiving instructions.
─
Bake a full rack with one type of bread and check for evenness of baking.

, select desired recipe, controller will
start heating. When setting temperature is reached, users are allowed to load the
oven with products.
2. During baking, users can start the baking timer, steam timer or open/close vent
during baking at any time if needed.
MAINTENANCE
CAUTION: For periodic maintenance and repairs, electrical diagrams are with the
unit.(on the back of the control door)
CAUTION: Service on this, or any other SINMAG appliance must be performed by
qualified personnel only.
CAUTION: Disconnect from power source when cleaning and/or servicing this unit.
CAUTION: Never attempt to clean this unit while it is hot as the risk of serious burn.
─
The oven can be cleaned with damp cloth. Do not clean stainless surfaces with
chlorine detergent and tools which may scratch stainless surfaces. It is important
to thoroughly remove the detergent left at the surface, but do not flush the oven
with water directly as it may cause short circuit.
─
Check that the air distribution system is clean. A dirty system might cause an
uneven baking result. The meshed sheets should be cleaned with a rigid brush or
compressed air.
─
After baking, open the loading door to release vaporous wastes and take residue
out of chamber. It can prevent next batch of products from peculiar smell and
taste.
─
Check control panel, door gasket, cable and water pipeline oftentimes to ensure
them in good condition.
─
If the circuit breaker trips, disconnect the unit from power supply and attempt to
reset. If the oven doesn’t work properly or still trips after reset, please ask
technician for a thorough check.
