It is most important that the oven is installed
correctly and that the operation is correct
before use. Installation shall comply with local
electrical, health and safety requirements.
BEFORE CONNECTION TO POWER SUPPLY
Unpack and check unit for damage and report
any damage to the carrier and dealer. Report
any deficiencies to your dealer. Fit the feet which
are packed inside the oven. Check that the avail-
able power supply is correct to that shown on the
rating plate located on the right-hand side panel.

LOCATION
To ensure correct ventilation for the motor and
controls the following minimum installation clear-
ances are to be adhered to:
Rear 0mm / 0“
Left-hand side 0mm / 0”
Right-hand side 75mm / 3.0”
Position the oven in its allocated working posi-
tion. Use a spirit level to ensure the oven is level
from side to side and front to back. (If this is not
carried out, uneven cooking could occur). The
feet/legs used with bench or floor mounting or
provided with stands are adjustable and will re-
quire adjusting in levelling the unit. It should be
positioned so the operating panel and oven
shelves are easily reachable for loading and
unloading.
2. INSTALLATION
WARNING: THIS APPLIANCE MUST BE GROUNDED.
WARNING: ALL INSTALLATION AND SERVICE REPAIR WORK MUST BE CARRIED OUT BY
QUALIFIED PERSONS ONLY.
Bench Mounting
For bench mounted applications the oven must
be fitted with 100mm / 4inch feet.
Floor Mounting
For floor mounted applications the oven must be
fitted with 150mm / 6 inch legs.
Note: Four 100mm/4 inch or 150mm/6 inch ad-
justable legs are available separately from your
E35 dealer as an optional extra.
Stand Mounting
Ovens that are to be mounted on stands do not
require feet or legs. Refer to Appendix B for
stand mounting instructions.
Avoid having heat producing equipment such as
fryers or steamers adjacent to the right-hand side
of oven.
BEFORE USE
Operate the oven for about 1 hour at 200°C
(400°F) to remove any fumes or odours which
may be present.
ELECTRICAL CONNECTION
Remove side cover panel to allow access to the
terminal block and strain relief cable clamp. The
cable can be fitted through the entry grommet
and secured from strain by tightening the fitted
strain relief bushing. Connect cable to the
terminals as marked. Refit cover panel.
IMPORTANT: FIXED WIRING
INSTALLATIONS MUST INCLUDE AN
ALL-POLE DISCONNECTION SWITCH.
Refer to specifications section for wire
connections required, and supply connection
conductor sizes.
IMPORTANT: THE OVEN VENT
LOCATED ON THE CABINET TOP MUST
NEVER BE OBSTRUCTED.

IMPORTANT: MAXIMUM INLET WATER
PRESSURE IS 550 kPa / 80 psi.
WATER CONNECTION
A cold water supply should be fitted to the water
inlet (3/4” BSP hose connection) which is located
on the rear of the right hand side of the unit.
Alternately, a connection elbow and sealing
washer is supplied with this unit for direct
connection of a 1/2” ID hose, which is
recommended for easy installation and service.
Connect water supply - Max inlet pressure 80psi /
550kPa.
Turn on water supply to check for leaks.
DOUBLE STACKING UNITS
When it is desired to mount an E35 Turbofan
oven on an E85 prover, a double stacking kit
must be used. Available from your dealer or Tur-
bofan distributor. (see Spare Parts).
When mounting one oven on top of another, a
double stacking kit is also required.
For stacking kit assembly instructions, refer to
Appendix A.
RACK WIDTH POSITIONS
The E35 models have an adjustable rack width
setting. This allows for the racking to be
configured for 405mm/16” or 460mm/18” wide
baking sheets/pans or racks.
Position the side racks in their innermost position
for 16” trays and in their outermost position for
18” trays.
Removal of Side Racks (as illustrated)
1) Lift the side rack off the bottom locating pins.
2) Move bottom of rack toward centre of oven.
3) Lower rack to clear top locating pins, and
remove.
Replacement of Side Racks
1) Insert rack into the oven, placing the
appropriate holes over the top locating pins.
2) Lift the side rack over the bottom locating
pins.
3) Lower rack with appropriate holes over bot-
tom locating pins.
RATING PLATE LOCATION
The rating plate for the E35 convection oven is
located at the bottom left corner of the RH side
panel. An internal rating plate is also located
behind the RH side panel on the vertical dividing
panel behind the electrical contactors. (Units
manufactured from July 2002).
