ELECTRIC COMBI OVEN
POWER SUPPLY
Connect the power supply as follows:
  Electrical and grounding
connections must comply with applicable
portions of the National Electrical Code
and/or other local electrical codes.
  Disconnect
the electrical power to the
machine and follow Lockout/
Tagout procedures.
1. Remove the right side panel from the oven.
The panel is held on by two screws on the
bottom and one screw on the top near the
back edge.
2. Wire to be sized per the National Electric
Code. Use copper wire rated for 125°C max.
3. Route the power supply cable through the
cable strain relief.
4. Connect the power supply cable to the
terminal block as shown on the label below
the terminal block.
5. Fasten the cable clamp firmly.
6. Reinstall the right side panel.

Grounding
The oven must be properly grounded.
Connect the ground conductor to the
terminal block in the position indicated on
the terminal block label.
   Plumbing connections must
comply with applicable sanitary, safety and
plumbing codes.
WATER REQUIREMENTS
Proper water quality can improve the taste of
the food prepared in the oven, reduce liming in
the oven cavity and extend equipment life.
Local water conditions vary from one location
to another. Ask your municipal water supplier
for details about your local water supply prior
to installation.
Presence of sediment, silica, excess chlorides or
other dissolved solids may lead to a
recommendation for alternate form(s) of water
treatment. Test the water with a TDS meter or the
test strip included with the oven. Other factors
affecting steam generation are iron content, amount
of chlorination and dissolved gasses.
Water Treatment
A local water treatment specialist should be
consulted before installing steam generating
equipment. It is recommended that you have
your water tested.
Supply Pressure
20-60 psig
Hardness*
Less than 3 grains
Silica
Less than 13 ppm
Total Chlorine/
0 ppm
Chloramine**
Chlorides***
Less than 30 ppm
PH Range
7 – 8
Undissolved Solids Less than 5 microns
* 17.1 ppm = 1 grain of hardness
** Total Chlorine of 4.0 ppm is the max limit for the
building water supply.  A carbon block filter must still be
used to remove all Chlorine and Chloramines from the
water.  Failure to do so will result in corrosion and rust in
the cooking cavity which is not covered under warranty.
*** If the Chlorides exceed 30 ppm and the oven is
used more than 8 hours during the day in steam or
combination mode the cavity will require rinsing every
8 hours. Failure to do so will result in corrosion and
rusting of the oven cavity and interior parts. RO water
treatment system can be installed to eliminate
chlorides from the water and reduce the hardness.
