SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
INSTALLATION/OPERATION INSTRUCTIONS HT-1 & HT-2 DISPENSERS
Mount the chemical dispenser unit in a convienent location on the wall.
VERY IMPORTANT: Do not use a domestic type detergent in this machine at any time. This type of detergent may damage
and/or obstruct pump operation or cause corrosion in the tank.
HT-1 DISPENSING EQUIPMENT- ELECTRICAL CONNECTION: Power and signal source for the detergent and rinse aid are pro-
vided as follows:
1. DETERGENT SIGNAL-White/red wire, signal (line voltage) for detergent dispensing. Connected between the normally closed
contact (N.C.) of C6 cam and the Detergent Pump Motor (SM) also connecting to the Detergent Prime Switch (S4). Detergent will
be dispensed during the rinse cycle.
2. DISPENSER POWER-White wire (line voltage). Connected between Detergent Primer Switch (S4) and the On/Fill-Off/Drain
Switch (S1).
All conduit and wiring for the interconnections is shipped pre-mounted to the HT-1 Chemical Dispensing Equipment. For connec-
tions to the dishmachine the wires terminate with butt splice connectors. When installing the chemical dispensing wiring match the
correct wire colors then crimp the connectors.
HT-2 DISPENSING EQUIPMENT- ELECTRICAL CONNECTION: Power and signal source for the detergent and rinse aid are pro-
vided as follows:
1. DETERGENT SIGNAL-White/red wire, signal (line voltage) for detergent dispensing. Connected between the normally closed
contact (N.C.) of C6 cam and the detergent terminal of the Speed Control Circuit Board (SC). Detergent will be dispensed during
the rinse cycle.
2. DISPENSER POWER-Red wire, (line voltage) Connected between “L2” and the “C” terminal on the step-down transformer in
the HT-2 box.
3. DISPENSER POWER-White wire (line voltage). Connected between “L1” and the appropriate line voltage terminal on the step-
down transformer in the HT-2 box.
4. RINSE AID SIGNAL-Blue wire, (line voltage). Signal for dispensing the rinse aid. Connected between the normally closed con-
tact (N.C.) of the C5 cam and the rinse aid terminal of the Speed Control Circuit Board (SC). Rinse aid will be injected into the final
rinse line during the rinse cycle.
All conduit and wiring for the interconnections is shipped pre-mounted to the HT-2 Chemical Dispensing Panel. For connections to
the dishmachine the wires terminate with butt splice connectors. When installing the chemical dispensing wiring match the correct
wire colors then crimp the connectors.
DETERGENT RECOMMENDATIONS: We suggest that you contact your local detergent specialist for the correct detergent for your
area.
LIQUID DETERGENT DISPENSING POINT: Liquid detergent will be dispensed into machine from factory supplied hole at back of
the tub above the basket strainer. Remove factory installed plug and install injector fitting for the detergent.
RINSE ADDITIVE INJECTION-FINAL RINSE LINE (HT-2 ONLY): Rinse Aid will be injected into the final rinse line at the rear of the
machine. Remove one of the 1/4” plugs from the line and install the rinse aid injector fitting.
TIMER ADJUSTMENT FOR DETERGENT CONCENTRATION: The amount of detergent may need to be increased or decreased
depending on water quality and type of detergent. It is factory set to dispense 15 ml of detergent into the wash water during the
rinse cycle. Consult your detergent representative for adjustment.
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 corresponds to the voltage listed on the data plate of the dishmachine. If not, contact 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 ser-
vice breaker and mark it as being for the dishmachine. Advise all proper personnel of any problems and of the location of the ser-
vice breaker. Replace the front kick panel and tighten down the screws.
