Water Connection - Unox XF Instruction Manual

WARNING :
Connect the electrical cable to the terminal board as
indicated in the drawing: insert screw-wise the copper
bridge and the electrical cable together under the
screw. Tighten the screw taking care that the cable and
the copper bridge are well gripped under the screw.
A wrong connection can cause an overheating of the
terminal board and burn it.
If the supply cord is damaged, you must substitute it
with a special cord available at UNOX or by its service
company.
SAFETY DEVICES
The appliance is equipped with a manually resetting
thermal breaking unit for protection against over-tem-
peratures, which completely deactivates the appliance
if there is an intervention.
Access to such a device is gained by removing the
black cap positioned to the bottom of the rear back: in
case of manual reset, push the button situated in the
centre of the device to bring the appliance into use
again.

WATER CONNECTION

WATER CONNECTION TO THE NETWORK
Connect the decalcified water inlet ducts placed on the
back of the oven to the specific distribution network by
means of a mechanical filter and a cut-off cock.
Before connecting the filters let a certain quantity of
water flow to clean the duct from any ferrous slag.
The water must have a hardness between 0.5°-5°F
(this in order to reduce the formation of limestone
deposits inside the electro-valve and inside the cook-
I. INSTRUCTIONS FOR THE INSTALLER
MAX 2 bar
ing chamber) and a pressure value between 0.5-2 bar.
The quantity of water which has to be vaporized inside
the oven must be regulated by means of the "micro-
cock" placed in the rear part of the appliance.
Regulate the microtap to inject only a trickle of water
on the fan.
An excess of water can cause a quantity of condensa-
tion too much elevated and flood the baking chamber.
CONDENSATION WATER DRAIN
The draining of the steam condensation water is posi-
tioned in the rear part of the oven and is to be con-
nected with a rigid or flexible pipe and convoyed to an
open drain.
Its diameter must not be lower than that of the drain
attachment and the length not greater than one metre.
The drain pipe must remain at least 20 cm below the
drain attachment in order to facilitate the downflow.
Avoid chokes on the flexible ducts or elbows for metal-
lic ducts, along all the run of the drain.
WATER CONNECTION TO EXTERNAL TANK
(Substitution of the electro-valve with the water pump)
Substitute the electro-valve with the water pump in the
models of oven for which is foreseen this optional
installation, proceeding as follows:
- remove the rear back of the oven
- disconnect the water charge pipe, situated inside the
oven, from the electro-valve
- remove the electro-valve from the oven
- set up the pump (4) on the support (5), insert the
pipe in the water exit connection and fix it by the
metallic fastener (6)
