The booster heater/wash tank heater interlock circuit removes power from the wash tank heater
whenever the booster heater contactor energizes. The illustration below shows how the booster
heater contactor is wired. The booster heater contactor is located on the backside of the control
panel bracket which is located behind the lower front access panel.
Interlock Circuit Operation
1. The glasswasher lls with water when the
main power switch on the glasswasher is
turned on. The booster heater thermostat
calls for heat which energizes the booster
heater contactor.
2. The auxiliary contact on the top of
the contactor opens and removes
power from the wash tank
heater.
3. When the booster heater thermostat
is satised, the booster heater
contactor deenergizes and the
auxiliary contacts close

240HT - Installation
Water Connections- 240HT
NOTE
Plumbing connections must comply with national, local plumbing and sanitary codes.
ATTENTION
Make sure that the flexible water supply and drain hoses are not kinked.
1. The 240HT has a 7ft. exible hot water ll hose with a 3/4" female garden hose connector.
2. A 1/2" or larger main incoming supply line should be installed to the glasswasher.
3. A 1/2" or larger shut-off valve should be installed in the water supply line as close possible
to the glasswasher for servicing.
4. A pressure regulating valve, PRV must be installed after the shut-off service valve if the
incoming ow pressure exceeds 20-22 psi.
5. The hot water supply must provide a minimum of 140°F/60°C, measured at the glasswasher
for the 40°F/ 22°C rise booster. For the 70°F/39°C rise booster the hot water supply must
provide a minimum of 110°F/43°C measured at the glasswasher.
Drain Connections - 240HT
1. All models have a 6ft. 5/8" I.D. drain hose. The maximum drain height connection must
not exceed 3 ft.[0.9 m].
2. The drain hose is located at the rear of the glasswasher.
3. The drain hose is secured to the rear of the machine by a clamp to maintain a gooseneck bend in the drain hose.
DO NOT KINK, STRETCH, OR LENGTHEN THE DRAIN HOSE.
4. Install the drain hose to a "WYE" drain tting.
Connection to a "TEE" tting will prevent the glasswasher from draining completely.
5. The maximum drain ow is 15 US gpm.
6. Make sure the drain hose does not kink. Kinks will prevent the glasswasher
from draining completely.
ATTENTION
The glaswasher will not drain correctly if the drain hose is connected to a disposer.
Connect the drain hose
to a WYE fitting.
Do not connect the drain
hose to a TEE fitting.

Chemical Dispensing Pumps
ATTENTION
Contact a local chemical supplier for detergent and rinse-aid chemicals.
The detergent should be a non-chlorinated liquid detergent.
The chemical dispensing pumps must be adjusted by the chemical supplier.
Model 240HT Hot Water Sanitization:
1. The 240HT is equipped with a built-in detergent dispensing pump and rinse-aid dispensing pump.
(See the photographs below.)
2. The pumps are located on a center bracket behind the lower-front access panel.
3. Each pump is equipped with 6 feet [1.8 m] of pick-up supply tubing, a stiffener tube, and a strainer.
4. A red label marked DETERGENT is attached to the detergent pump inlet tubing.
5. A blue label marked RINSE-AID is attached to the rinse-aid pump inlet tubing.
6. The detergent enters the wash tank compartment through a tting at the right rear of the wash
compartment.
7. The detergent supply should be a non-chlorinated liquid detergent.
8. The rinse-aid enters the nal rinse piping through a tting located on the upper-right rear side of the
glasswasher. The tting is located near the vacuum breaker.
For Model 240HT, the dispensing pumps are located
on the center bracket behind the lower-front access
panel.

9. The chemical supplier will choose the appropriate liquid rinse-aid.
10. The factory chemical dispensing pump settings are only approximations; therefore,
your chemical supplier must adjust the dispensers for the supplied product.
11. Place the chemical supply containers as close to the glasswasher as possible.
12. Do not elevate the chemical containers above the nished oor.
For Model 240HT detergent enters the wash tank
compartment through a fitting on the rear wall of the wash tank

MD240-HT - Initial Start-Up
Chemical Dispensing Pumps
Chemical Dispensing Pump Speed and Tank Fill Adjustments
The chemical dispensing pump speeds are not set at the factory. Variations in the
type of chemicals supplied by the chemical supplier always require that the supplier
make nal adjustments for the products supplied.
1. Adjustment screws are provided for the dispensing pumps and for the wash tank ll.
They are located on the right-side of the glasswasher behind the lower front access panel.
2. Make sure the chemical containers are full and the pick-up tubes are in the proper
containers.
3. Turn the glasswasher power switch ON. The switch will illuminate and the glasswasher
will ll with water.
4. Run a normal glasswasher cycle and test detergent and rinse-aid concentrations
according to the chemical supplier's instructions.
CAUTION
Excessive pressure to the potentiometers when adjusting
can result in bent or broken adjusting screws.
5. Each dispensing pump has a clearly marked
adjustment screw. Turn the screw CW to
increase the time of the dispensing pump
and CCW to reduce the dispensing pump
time.
6. The Fill adjustment screw will provide a
small change in the tank water level.
If a large adjustment is needed, then
check the incoming water pressure and
make sure the ll hose is not kinked. If these
items are okay, then the size of the incoming
water supply should be evaluated.
7. The 240HT uses detergent and rinse-aid
only, a sanitizer is not required.
