4. INSTALLATION
4.1 ELECTRICAL CONNECTION
•
Connection to the electrical power source must be done according to all state and local codes. Before
connecting your oven, make sure that the voltage and the amps comply with those stated on the data plate
of your oven. Avoid using patch cords and multiple jacks.
•
The appliance must be placed so that the connection plug to the outlet can be easily reached.
When the appliance is in operation, the power supply voltage must not diverge from the value of the
nominal voltage, written on the technical data plate, by more than + or – 10%.
•
Ovens are equipped with cordset and NEMA plug (single phase; 120V or 208-240V, depending on oven
model.) It is sufficient to insert the plug in the proper outlet (the outlet must be suitable for the plug
assembled on the oven.)
4.2 WATER CONNECTION
(available on all digital models EXCEPT XAFT-111 & XAFT-130, per
below)
•
WARNING: The water supplied to the oven must be free from chloramine, or else with levels not
exceeding .5ppm. Any damage caused by chloramine within the water is not covered by warranty.
•
WATER SUPPLY SPECIFICATIONS
♦
Water supply must not exceed 86°F, and must be potable.
♦
Water must have a maximum conductivity of 150
μ
S/cm. If greater than 150
μ
S/cm, use a filter to
avoid limescale and/or other minerals from depositing inside the oven.
♦
Water must have a hardness between 0.5° and 5°F (to avoid formation of lime deposits inside the
electric valve and inside the cavity).
•
CONNECTION TO THE WATER NET: Full Size digital oven models (XAFT-188 & XAFT-195)
come with an electrovalve for direct water connection.
♦
A mechanical filter must be placed between the water system and the water connection of the oven.
♦
Before connecting the water pipe to the oven, flush it out with water, to clean the duct from any
residue.
♦
A shut-off valve should be positioned between the water supply and the oven.
♦
Water used in the oven must have a pressure between 22 – 87 psi (150-600 kPa). If the pressure of
water supply at the inlet is too low (22 psi/1.50 bar), a pump with a suitable flow rate should be used
(minimum flow rate of 1.32 gpm (300 l/h).
♦
Cadco suggests you use a decalcification filter in order to maintain fan balance.
•
AUXILIARY WATER PUMP: Half Size digital ovens with Dynamic control panels (XAFT-115 &
XAFT-135)
come with an EL080 Auxiliary Water Pump included, for manually pumping water from a
bucket or other container.
WARNING:
Before using the water pump, always make sure that there is
water in the tank. Damage to the pump can occur if it is operated without water in the tank and it will
void your warranty. If the pump makes “groaning” sounds, it is probably due to lack of water in the tank
or the pump is simply running an air bubble through the system.
•
Hot air and steam will exit the oven from the back exhaust port. During most cooking cycles, you will
have hot and humid exhaust coming out from this exhaust port (temperature and humidity of this exhaust
depend on the cooking parameters being used.) The steam that comes out of the exhaust port can also be
vented outside if desired.
II. INSTRUCTIONS FOR THE USER
Never allow grease splatters or spills to collect on the inside walls, floor, or ceiling of your oven. A
simple cleaning with soap and water is usually enough to keep your oven spotless and in “like new”
condition for years. Your oven should never be cleaned with a water hose or anything more powerful
than a spritz bottle. For tougher cleaning and built up grease, we suggest using Foam Plus® from
Discovery Products Corporation (Tel. 877.822.8500.)
