International Plumbing Code,
International Code Council (ICC) or
the Uniform Plumbing Code,
International Association of Plumbing

After unpacking the machine, first check the
delivery against the packing slip to ensure that it
is complete, and inspect for damage that may
have occurred during transportation. Immediately
report any damage to the carrier, t he insurance
company and the manufacturer.
Setting Up and Alignment:
When setting up the machine, remember that the
machine gives off steam during operation (when
you open the door). Protect adjacent wooden furni-
ture to prevent it absorbing moisture and swelling.
CAUTION:
Protect the washer against frost. Systems that carry
water can be damaged if they freeze.
The machine must be completely level when
installed. Adjust the machine’s feet to compensate
for any unevenness of the floor.
CAUTION:
Note all the information on the enclosed connection
diagram. For the machine to work correctly, the
required water pressure and flow rate must be
guaranteed at all time.
Connection to the Wa ter Supply:
• Use a ball valve and a pressure reducing valve
for the water supply and drain near t he washer
and in an easily accessible position. It should
not be located behind the washer.
• PRV should be set to supply 20 psi flow
pressure.
• The washer is equipped with a drain pump.
The maximum drain pump lift above floor is 24”.
Connection to the Wa ter Supply (continued) :
• Connection should provide for a minimum of
24” (600mm) of flexible line at machine so that
unit can be moved for cleaning. Note: Unit is
provided with 37” (940mm) flexible connections.
Connection to the Drain:
Unit must be connected to drain capable of han- dling
4.75 gal/min flow and must be provided with
a proper air gap at connection. Failure to provide
air gap will result in improper or inconsistent drain-
ing of unit and potential overflow condition. The
maximum height of the drain connection is 24”.
Connection to the Power Supply:
Before using the washer, check that all electrical
protection systems are working correctly.
Attention: The machine should not be regarded
as isolated from the power supply unless
switched off at the customer’s main switch.
• The total amp load is 20 fla.
• The electrical connection of the washer is to
be fused by the customer with time-lag fuses
or circuit breaker according to wattage (see
the machine rating plate) . No other appliances
may be fused with the washer.
• Install according to local regulations, this unit
requires a 30 amp circuit breaker in t he electric
supply.
• Connect the power cord to the customers
power system, make sure the unit is properly
grounded. Unit comes equipped with a NEMA
L6-30P plug.
• The power cord comes attached from the
factory, if replacement is needed it must be
done by certified personnel only.
Final Tasks:
The washer must be connected to all services
(electricity supply and to the fresh water and waste
water systems), prior to testing the machine &
installation . Make sure incoming water line is f lushed
of debris before connecting to unit.

PART 3 OPERATING INSTRUCTIONS
OPERATING INSTRUCTIONS
Chemical Connections:
The RL-30 is supplied with integral detergent and
rinse additive pumps and the chemical hoses are
located on t he side of the dishmachine.
Detergent concentration should be between .25%
(.30oz/gal) and .30% (.38oz/gal). Note: Always
consult chemical manufacturer for proper
concentration.
Preparing for operation:
• Locate the clear chemical pick up tubes on the
side of the un it
• Identify the detergent pick up tube (smaller
diameter ID tube) and place it in the container
of commercial liquid de t ergent.
• Place the rinse additive pick up tube (larger
diameter ID tube) in the container of commercial
liquid rinse additive.
Priming the system:
• The detergent pump is self priming and runs
during the rinse/fill cycle. The amount of
detergent dispensed is controlled by the speed
of the peristaltic pump. This can be adjusted by
turning the control screw.
• The rinse additive pump is located behind the
front kick panel. The pump is a diaphragm type
pump and can be primed by inserting a
screwdriver into the screw on t he front/top of the
pump, turning counter clockwise and then
depressing the screw to begin the manual
priming. Make several compressions until you
see the rinse additive solution entering the check
valve on the other side of the pump. The amount
of rinse additive that is added to the system can
be adjusted by turning the screw clockwise to
decrease and counterclockwise to increase.
Once set, the solution is then added
automatically to the rinse system.
