INSTALL AND CONNECT WATER SUPPLY LINES
Furnishing and plumbing the water supply lines is the responsibility of the owner and/or
installer. This section explains the plumbing layouts recommended by the Manufacturer.
When installing and connecting the water supply lines to the Oven/Steamer, observe the
following guidelines and instructions.
The Oven/Steamer has compression fittings at the back of the unit for connection to the
water supply lines. The steam generator and humidifier fitting (
on dimension drawing)
is 3/4” IPS and the condenser and boiler rinsing fitting (
on dimension drawing) is 3/4”
IPS.
Always connect untreated COLD water supply to the Oven/Steamer condenser/boiler rinsing
water supply line. DO NOT USE HOT WATER. The Oven/Steamer will not function properly or
within design safety limits if hot or warm water is supplied.
Do not connect the to a softened or treated water supply which adds chlorine or chloride
salts to the water. Refer to the Softened, Treated, or Filtered Water instructions on page 21
for details.
Supply water must have a minimum dynamic pressure of 35 psi (2,4 kg/cm
2
) and a maximum
static pressure of 60 psi (4.1 kg/cm
2
). Water pressure greater than 60 psi will cause damage
to the solenoid valves. Local water pressure can be 100 psi or more.
If possible, check supply pressure at non-peak demand time. A local water company can
assist in this check. If static pressure exceeds 60 psi water, a pressure regulator must be
installed in the supply lines. For best results, set the regulator for 50 psi dynamic pressure.
Refer to the recommended plumbing layouts in Figures 2-6 and 2-7, and install the water
supply lines and fittings in accordance with all local and national codes.
While constructing and installing the water supply lines, pay particular attention to the
following requirements and recommendations.
