3.15 Steam System Connections

IMPORTANT
In some cases, local codes dictate that steam
system connections be made only by a
certified professional.
The steam supply and condensate return
connections are located behind an access
panel on back wall of the machine, at the
unload end. Both connections are 3/4" male
NPT. See Figure 3-12.
If the machine is against a wall, you can
remove the water connection access panel
to reach the steam supply and condensate
return connections, as shown in Figure 3-10
on the previous page.
The steam supply connection is on the
outboard side (closest to the end of the
machine). The condensate return is on the
inboard side (further away from the end of
the machine).
Note that the condensate return is only for
the steam system of the dishmachine. A
steam booster heater, or a steam supply line
with an upward slope, will require individual
condensation removal systems (moisture
trap, pump, etc.) that are in compliance with
all applicable local codes.
1. Check the incoming steam pressure. At
the machine connection, pressure should
be 10-29 psi and constant.
2. Check that the volume of steam delivered
is sufficient for proper operation. The
dishmachine requires 60 lbs./hr. of steam
at 10-29 psi (not including an external
steam booster heater, if one is present).
3. Connect the customer-supplied steam line
to the machine's steam connection. The
machine's connection is 3/4" NPT male.
4. Plumb the condensate return connection
to a floor drain as per local codes. The
machine's condensate return connection
is 3/4" NPT male.

3.16 Drain Connection

IMPORTANT
In some cases, local codes dictate that drain
connections be made only by a certified
professional.
The machine is equipped with a 2-15/16"
(75mm) OD vertical, gravity-fed drain. The
machine requires a 4" or larger floor drain.
See Figure 3-13.
1. In some cases, a grease trap (supplied
by others) must be fitted into the waste
water line. If a trap is required for your
installation, check that it is present.
2. If possible, the machine drain can simply
be positioned directly above a floor drain,
as shown in Figure 3-13.
3. If a floor drain is not directly beneath the
machine drain, or if local codes require a
trap, a drain line can be attached using
the supplied rubber boot and clamp. Using
the boot and clamp, the machine drain can
be connected either to a 3" OD drain line,
or to a 3" NPT pipe (using the supplied 3"
NPT adapter). Choose a piping material that:
• Complies with any applicable local and
national codes.
• Is rated for use with water temp-
eratures up to 180°F.
• Is rated for 3-12 pH to accommodate
detergents and rinse aid in the drain
water.
