Jackson JPX-300H Dishwasher User Manual


 
SHOCK ABSORBER: It is also recommended that a shock absorber (not supplied with the JPX-300 series models) be installed
in the incoming water line. This prevents line hammer (hydraulic shock), induced by the solenoid valve as it operates, from
causing damage to the equipment.
CONNECTING THE DRAIN LINE: The JPX-300 series machines are a pumped (pressure) drain capable of pumping waste
water to a height of 24 inches from the floor to the kitchen’s drain system. The dishmachines are supplied with a 10 foot long
hose that extends from the rear side of the machine. There must also be an air gap between the machine drain line and the
floor sink or drain. If a grease trap is required by code, it should have a flow capacity of 12 gallons per minute.
PLUMBING CHECK: Slowly turn on the water supply to the machine after the incoming fill line and the drain line have been
installed. Check for any leaks and repair as required. All leaks must be repaired prior to placing the machine in operation.
ELECTRICAL POWER CONNECTION: Electrical and grounding connections
must comply with the applicable portions of the National Electrical Code
ANSI/NFPA 70 (latest edition) and/or other electrical codes.
Disconnect electrical power supply and place a tag at the disconnect switch to
indicate that you are working on the circuit.
The dishmachine data plate is located on the front of the machine. Refer to the
data plate for machine operating requirements, machine voltage, total amper-
age load and serial number.
To install the incoming power lines, remove the kick panel. This will require tak-
ing a phillips head screwdriver and removing the two screws at the bottom of
the kick panel; open the door slightly while carefully lifting the kick panel up
and out of the way. 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 ground-
ing lug. Install the service wires (L1 and L2) 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.
VOLTAGE CHECK: Ensure that the power switch is in the
OFF position and apply power to the dishmachine. Check
the incoming power at the terminal block and ensure it cor-
responds to the voltage listed on the data plate. If not, con-
tact a qualified service agency to examine the problem. Do
not run the dishmachine if the voltage is too high or too
low. Shut off the service breaker and mark it as being for
the dishmachine. Advise all proper personnel of any prob-
lems and of the location of the service breaker. Replace
the control box cover and tighten down the screws.
CHEMICAL CONNECTIONS: All chemical hookup loca-
tions are located on the back of the dishmachine. Please
refer to the drawing at the right for the correct connection
point. The JPX-300H/HC/HN dishmachines are supplied
with integral detergent and rinse aid chemical feeder
pumps. The JPX-300L dishmachine is supplied with inte-
gral detergent, rinse additive and sanitizer chemical feed-
er pumps.
Please refer to page 11 for instructions on priming the chemical feeder pumps.
