GENERAL INSTRUCTIONS

(INSTALLATION)

Note: Read the following instructions carefully, proper installation of your Conserver Dishwasher

will ensure proper machine operation.

1. Cut straps holding machine to base of crate, ease machine on to floor and move into place of
installation.

2. Connect drain line to bottom of machine (2 IPS female fitting on front of machine) to conform with
local and/or national codes. Drain is a gravity feed system from the machine.

a. The Conserver is designed to accommodate an external scrap trap if one is shipped with the

unit. The scrap trap should be placed beneath the unit with the top opening to the right of the
pump and motor mounting shelf so that the top hole of the scrap trap is in line with the drain
opening from the machine.

b. Direct the drain line from the dishwasher to the top of the trap and plumb accordingly with 2"

pipe of the necessary length. Connect a 2" fitting to the back of the scrap trap and plumb to the
drain line. The drain line is a gravity feed system from the dishwasher to the scrap trap and also
from the scrap trap to the drain line. Scrap trap aids sluggish drains by containing machine
water as it drains and letting it drain off slower.

3. Connect incoming ¾" water line with capacity to supply 10.5 gallons per minute with a flow pressure
of 20 PSI at a temperature of 140 degrees fahrenheit. This connection is just before the Y-strainer.
Connect to conform with local and/or national codes (standards). a. It is recommended that in areas
where there is fluctuating water pressure a restrictor valve allowing 8 gallons of water per minute be
installed. This will help to provide a steady fill rate. The restrictor should be located down the line
from the Y-strainer.

4. Install the proper circuit breaker, wire and conduit size to conform with local and/or national codes.
Refer to data plate for electrical rating.

5. Electrical connections are made to the circuit breaker located in the dispenser/control box on top of

the machine. The circuit breaker is located on the side of the box with a grounding lug next to it.
Three wires L1, N and a ground wire should be passed through the hole in the back of the box and
pulled over to the top two terminals of the circuit breaker. Wires L1 and N are connected to the top
two terminals of the circuit breaker and the ground wire connected to the grounding lug next to the
circuit breaker.

6. Do not apply power until step # 9.

7. Turn on water supply to machine; check for any leaks in plumbing and connections.

8. Place the open end of the red tube into a container of detergent, white, into a container of sanitizer

and blue, into a container of rinse additive.

9. To energize electrically, proceed as follows:
a. Turn on customer's circuit breaker controlling the machine.
b. Check voltage at incoming terminals L1 and N, it should match data plate voltage. Voltage at
L1 should be checked to ground to ensure that a high (or wild) leg is NOT connected.
(Voltage exceeding 150V to ground would indicate a high leg).
c. If voltages are in required range, turn on circuit breaker on the side of the dispenser/ control

box.

10. To fill the unit with water:
a. Located on the right side of the control box are two rocker type momentary switches. To fill this

unit initially with water, push and hold the fill switch to the top of the unit until the water
reaches the overflow hole the side of the drain stopper. Release the switch and it will return to
the center position.

b. After the unit is full of water, check for leaks and see if the solenoid valve opens and closes as

the fill switch is turned on and off.

c. After checking the plumbing lines for leaks, run the unit through a complete cycle to determine

the proper water level. The proper level for the water is the overflow hole in the side of the
drain stopper if this level is either not reached or is exceeded, please turn to the timer section
of this manual to determine the proper adjustment of the timer that has to be made.

TIMER ADJUSTMENTS

The timer is a self-contained (frame-mounted) timer of the repeating cycle type. It is mounted in the
control box on the top of the machine to control the automatic functions of the machine. The timer motor
operates on 110 VAC, 60 cycles, taking 90 seconds to complete one full revolution. There are six micro
switches which are controlled by rotating cams driven by the timer motor. Two of the cams are fixed and
cannot be adjusted. The remaining four cams are adjustable and can be adjusted to either lengthen or
shorten the desired operation.

Remove the power to the machine when making all timer adjustments.
Included and taped in each control panel is a spanner wrench (as shown in the drawing). This wrench is

needed to adjust the cams on the timer. The cams are preset at the factory but may have to be
readjusted for different conditions of the country and for the different brands of detergent, rinse additive
and sanitizing solutions. On both sides of the four adjustable cams, there are holes into which the
spanner wrench is placed to apply leverage to make the desired change. The left side of the cam will
always start an operation and the right side will end it The cam on the right side is the one that will be
adjusted more often since this one determines the length of the operation.

When making adjustments to the timer cams be sure that the first cam next to the timer motor is in its
stop position in the notch. Place one hand over the timer motor with your thumb lodged next to or on the
first cam so that it will not move when the other cams are being adjusted. To make the adjustment, place
the wrench in the holes on the right side of the cam. If a longer operating time is desired, increase the
gap between the left and right side of the cam. If a shorter operating time is desired, decrease the gap
between the left and right side of the cam. At the extreme end from the timer motor, there is a cam
marked in five-degree increments. Every four degrees equals one second of the timer's revolution.

Function of each micro switch starting from the timer motor and going left to right:
Timer Motor Micro Switch: controlled by a fixed cam that controls the total length of the cycle. It is

activated by engaging the fill/start switch in the start position.
Detergent Micro Switch: controlled by an adjustable cam. It operates the peristaltic pump that

dispenses the detergent. By adjusting the right side of the cam, you can either increase or decrease your
amount of detergents.

Drain Solenoid Micro Switch: controlled by a fixed cam. It opens the solenoid valve during the cycle
that drains the wash water out of the unit.

Fresh Water Solenoid Valve Micro Switch: controlled by adjustable cam. It is important that the unit
have two-and-a-half gallons of water in it during the wash and rinse cycles. The proper level indicator is
the height of the cut-out leading into the drain strainer and stopper. By adjusting the right side of the
cam, you can either increase or decrease your water supply to meet this required level. Fill water is
turned on before drain cycle ends to insure machine is flushed before filling.

Rinse Agent Micro Switch: controlled by an adjustable cam. It operates the peristaltic pump that
dispenses the rinse agent. By adjusting the right side of the cam, you can either increase or decrease
your amount of rinse additive. It should activate during the fill cycle.

Sanitizing Agent Micro Switch: controlled by an adjustable cam. It operates the peristaltic pump that
dispenses the sanitizer solution. By adjusting the right side of the cam, you can either increase or
decrease your amount of sanitizer solution. It should activate during the fill cycle. When the timer is
preset at the factory, it is set to dispense 15 milliliters of detergent 11 milliliters of rinse additive and 9.5
milliliters (50 parts per million) sanitizing agent based on an 8.4% solution of Sodium Hypochlorite.
