A water hammer arrestor (meeting ASSE-1010 Standard or equivalent) should be installed (supplied
by others) in the common water supply line at the service connection.
The plumber connecting this machine is responsible for making certain that water lines are THOROUGHLY
FLUSHED OUT BEFORE connecting to the dishwasher. This "ush-out" is necessary to remove all
foreign matter, such as chips (resulting from cutting or threading of pipes) pipe joint compound from the
lines; or, if soldered ttings are used, bits of solder or cuttings from the tubing. Debris, if not removed,
may lodge in the dishwasher's plumbing components and render them inoperative. Manual valves
or solenoid valves fouled by foreign matter and any expenses resulting from this fouling are NOT the
responsibility of the manufacturer and associated repair costs are not covered under warranty.
Water supply requirements are as follows:
MODEL TEMPERATURE
LXeC 120°F Minimum
LXePR 120°F Minimum
LXeH 110°F Minimum
LXeR 55°F Minimum, 80°F Maximum
NOTE: On LXeR installations, if cold water supply temperature is consistently above 80°F or if excessive
water vapor or steam is entering the room after the condensing cycle is complete, contact Hobart
Service to increase condensing time.
Required owing water pressure to the dishmachine is 15-65 PSIG. If pressures higher than 65 PSIG
are present, a pressure regulating valve must be installed in the water line to the dishmachine (by
others). If owing pressure is less than 15 psi, improper machine operation may result. All LXe models
are equipped with a pumped rinse system; therefore, a water pressure gauge is not required and is
not supplied with the machine.
The water pressure regulator must have a relief bypass. Failure to use the proper type
of pressure regulator may result in damage to the unit.
A manual shutoff valve (not supplied) should be installed upstream of the ll hose to accommodate
servicing the machine.
It is recommended that a line strainer (not supplied) be installed in the supply line between the manual
shutoff valve (not supplied) and the connection point on the machine. Make plumbing connections with
1
⁄2" minimum copper piping OD (
3
⁄4" recommended), with a
3
⁄4" male garden hose tting (not supplied).
See installation diagrams, pages 16-17.
PLUMBING CONNECTIONS
Plumbing connections must comply with applicable sanitary, safety, and plumbing
codes.
Drain
A drain hose,
5
⁄8" inside diameter and 6' long, is provided. This should be securely plumbed into a
drain. Use care not to kink hose. See installation diagrams, pages 16-17. Drain must have a minimum
ow capacity of 5 gallons per minute.
