All electrical ratings provided in this manual are for reference
only. Always refer to the machine data plate to get exact electrical
information for this machine. All electrical work performed on
machines should be done in accordance with applicable
local, state, territorial, and national codes. Work should only
be performed by qualied electricians and authorized service
agents.
Note that all electrical wiring used in this series of machines must
be rated, at a minimum, for 212 °F (100 °C), and that only copper
conductors must be used.
Where applicable, heating element amperage draws have been
adjusted for the assumed input voltage. The manufacturer
assumes incoming voltages will be either 208 or 230 V. Some
heating elements used in the machines are rated for other voltages,
such as 240 V and 480 V. Always verify the amperage draw of the
machine in operation when sizing circuit protection.
If the dishmachine is equipped with the optional rinse heater, note
the rinse heater might have its own electrical connection and
require a separate service. Amperage loads for motors and heaters
are indicated on the machine data plate.
The electrical congurations of this series of machines are as
follows:
Available Electrical Characteristics:
UH30-FND

Before installing the unit, check packaging and machine for damage. Damaged
packaging might be an indication of damage to the machine. If there is any type
of damage to both packaging and unit, do not throw away the packaging. The
dishmachine has been inspected at the factory before shipping and is expected to
arrive in new, undamaged condition. However, rough handling by carriers or others
might result in damage to the unit while in transit. If this occurs, do not return the unit to
the manufacturer. Instead, contact the carrier and ask them to send a representative
to the site to inspect the damage and request that an inspection report be completed.
Contact the carrier within 48 hours of receiving the machine as well as the dealer that
sold you the unit.
Remove the box and machine from the pallet before installing. Open the front door and
remove all of the materials from inside. Once unpacked, verify there are no missing
parts (reference the Parts section). If a part is missing, contact the manufacturer
immediately.
All plumbing connections must be made to adhere to local, state, territorial, and
national codes. The installing plumber is responsible for ensuring the incoming
water lines are ushed of debris before connecting to the machine. Note that chips
and materials from cutting processes can become lodged in the solenoid valves
and prevent them from opening or closing. Any valves that are found to be fouled
or defective because of foreign matter left in the water line, and any subsequent
damage, are not the responsibility of the manufacturer.
A water hardness test must be performed. A hardness test kit can be found on the
warning tag that is attached to the incoming plumbing connection on the back of the
machine. If water hardness is higher than 3 GPG, install a water softener or install the
optional Scale Prevention System (SPS). See the Plumbing Options page and the
next section for more information on the SPS.
See the Machine Dimensions page and reference item "B" for water inlet connection
location.
The manufacturer does NOT endorse "Tankless On-demand" water heaters
for use with their dishmachines. The manufacturer DOES endorse, and highly
recommends, the standard "Tank" style water heaters, sized to properly handle the
water heating requirements of the facility.

A water hardness test must be performed. There is a hardness test kit on the warning
tag attached to the incoming plumbing connection on the back of the machine. If
water hardness is higher than 3 GPG and a water softener is not being used, install
an SPS (see Plumbing Options page) into the water line between the facility water
line and the machine water line (installed at the factory). Observe proper inlet/outlet
water directions. A water shut-o󰀨 valve should be installed before installing the SPS
to allow access for service. The water supply must be capable of a minimum of 20 ±
5 PSI “ow” pressure at the recommended temperature indicated on the data plate.
If water hardness tests at 3 GPG or lower, connect the machine water line (installed
at the factory) to the facility water line. A water shut-o󰀨 valve should be installed in
the water line between the facility supply and the machine to allow access for service.
The water supply line must be capable of a minimum of 20 ± 5 PSI “ow” pressure at
the recommended temperature indicated on the data plate.
The manufacturer has an optional water pressure regulator to accommodate areas
where water pressure uctuates or is higher than the recommended pressure. Take
care not to confuse static pressure with ow pressure: static pressure is line pressure
in a “no ow” condition (all valves and services are closed); ow pressure is the
pressure in the ll line when the valve is opened during the cycle. See the Plumbing
Options page.
It is suggested that a shock absorber (not supplied) be installed on the incoming water
line. This prevents water hammer (hydraulic shock)—induced by the solenoid valve
as it operates—from causing damage to the equipment. See the Plumbing Options
page.
The dishmachine has a pumped (pressure) drain capable of pumping waste water
to a height of 24” above the oor to the kitchen’s drain system. Each dishmachine is
supplied with a drain hose. When installed, it will extend from the rear of the machine.
There must be an air-gap between the machine drain line and the oor sink or drain.
If a grease trap is required by code, it should have a ow capacity of 12 GPM.
After installing the incoming ll line and the drain line, slowly turn on the water supply
to the machine. Check for any leaks and repair as required. All leaks must be
repaired before operating the machine.
Take care not to confuse
static pressure with
ow pressure!

The data plate is located at the left-front side of the dishmachine. Refer to the data plate
for machine operating requirements, machine voltage, total amperage, and serial number.
Remove the back panel and set aside. This will require removing the screw at the
bottom of the back panel with a phillips screwdriver. Install 3/4” conduit into the pre-
punched holes in the back of the control box. Route power wires and connect to power
block and grounding lug. Install the service wires (L1 and L2 for UH30-FND, L1 and
N for UL30/UL30H) to the appropriate terminals as they are marked on the terminal
block. Install the grounding wire into the lug provided. It is recommended that “DE-
OX” or another similar anti-oxidation agent be used on all power connections.
UH30-FND UL30/UL30H
Ensure that the "ON/OFF" switch is in the "OFF" position and apply power to
dishmachine. Check the incoming power at the terminal block and ensure it
corresponds with the voltage listed on the data plate. If not, contact a qualied service
agency to examine the problem. Do not run dishmachine if voltage is too high or too
low. Shut-o󰀨 the service breaker and advise all proper personnel of the location of
the breaker and any problems. Replace the control box cover and tighten-down the
screws.
This is a commercial dishmachine and reaches temperatures that can exceed
those generated by a residential machine. Surrounding countertops, cabinets, ooring
material, and suboor material must be designed and/or selected with these higher
temperatures in mind.
Any damage to surrounding area that is caused by heat and/or moisture to materials
that are not recommended for higher temperatures will not be covered under warranty
or by the manufacturer.
The thermostats on this dishmachine have been set at the factory. They should only
be adjusted by an authorized service agent.

Proper preparation of ware will help ensure good results and fewer re-washes. If not
done properly, ware might not come out clean and the e󰀩ciency of the dishmachine
will be reduced. Putting unscraped dishes into the machine a󰀨ects its performance,
so scraps should always be removed from ware before being loaded into a rack.
Pre-rinsing and pre-soaking are good ideas, especially for silverware and casserole
dishes.
Place cups and glasses upside-down in racks so they don't hold water during the
cycle. The dishmachine sanitizes as well as cleans. To do this, ware must be properly
prepared before being placed in the machine.
To wash a rack, open the door completely and slide the rack into the unit. Close the
door, ensure the "WASH/DELIME" switch is on "WASH," press the "Start" button, and
the unit will start. After the cycle light turns o󰀨, the cycle is complete. When the ush
light is on (steady, not ashing), tank water should be drained and relled.
Based on use, the strainer might become clogged with soil and debris as the
workday progresses. Operators should regularly inspect the strainer to ensure it has
not become clogged. If clogged, it will reduce the washing capability of the machine.
Instruct operators to clean out the strainer at regular intervals or as required by
workload.
1. At the end of the workday, close the door. Flip the “ON/OFF” switch to the “OFF”
position.
2. The drain pump will activate and empty the unit of water.
