INSTALLATION INSTRUCTIONS

Part 2, Section A

2.A.1 PLACEMENT

2.A.1.1 Carefully uncrate machine. Take caution to not damage components which

may be mounted on the top or sides of the machine.

2.A.1.2 Set unit in place and adjust the feet to level the machine.

2.A.1.3 Fasten the tables to the load and unload side of the machine. Most

installations require fastening the turn-down lip of the dish tables to the side of the

machine with flathead counter-sunk screws. The table design should provide horizontal

clearance of 30" for servicing.

2.A.2 ELECTRICAL CONNECTIONS

2.A.2.1 Connect electrical lines sized for the correct voltage, current and phase of the machine.

These should agree with machine requirements indicated on the nameplate and labels in control

panel. This Fuse Sizing Chart should be used as a guide for proper line protection:

Caution

Connections must be made to a circuit breaker or fused disconnect

as provided by the end-user and required by local codes. A laminated

wiring diagram is inside the control panel

INSTALLATION INSTRUCTIONS

Part 2, Section A

2.A.2.2 On machines not provided with a single-point connection there is an electrical connection

required for the, 1. Pumps and control circuit, and Wash tank heater.

2.A.2.3 If an electrical booster is provided connect the power directly to the booster.

Caution

As with any 3 phase system, an electrician must check all motors for proper

phasing, i.e., Pump motors must be running in direction

indicated by arrow on housing.

2.A.3 MECHANICAL CONNECTIONS

2.A.3.1 Connect 140°F water lines for tank fills/booster as tagged and noted on the

installation drawings.

2.A.3.2 If machine is provided with steam heat connect the steam lines and steam

condensate lines as tagged and noted on installation drawings.

2.A.3.3 Connect the drain line.

Caution

Drain lines must be as specified on installation drawings. Drain line should

be properly vented and should have fall of not less than 1/4" to the foot of

proper flow. Some area plumbing codes require drains to flow into an open

gap with an opening twice the diameter of the pipe. Check with your local

plumbing codes for the type of drain connection required.

Caution

All lines must be flushed prior to use to remove debris.

Caution

Do not reduce the size of lines as specified in installation drawings. All

lines are sized to facilitate necessary flows, pressures, etc.

INSTALLATION INSTRUCTIONS

Part 2, Section A

2.A.4 HVAC

2.A.4.1 Ventilation system should be sized to provide adequate ventilation per machine specs.

Refer to spec sheet.

2.A.5 CHEMICALS

2.A.5.1 Upon completed installation of the dishwasher contact a local detergent/chemical supplier

for the correct chemicals for your area.

2.A.5.2 Electrical connection points for the detergent dispenser and rinse injector are located

inside the control panel. Refer to the wiring diagram for this machine for the proper connection

points. Dispensers may be connected on either the primary voltage side of the machine or the

24VAC control voltage side.

Caution

When connecting on the 24VAC control voltage side of the

transformer, total VA must not exceed 50VA.

2.A.5.3 The detergent density probe should be installed in the hole provided & labelled in the wash

tank.

2.A.5.4 The switch on the control panel labelled "Manual" and the switch labelled "Wash" may be

used when de-liming the machine. When activated, these switches keep the machine in an

indefinite wash cycle. This feature can also be used to wash heavily soiled ware.

2.A.6 Tabling

2.A.6.1 Load and unload tables should be pitched towards the machine to return excess water

into the machine.

OPERATION & CLEANING INSTRUCTIONS

Part 2, Section B

Insinger dishmachines are user-friendly, making them the easiest dishwashers to operate and maintain.

By following the operation procedure and general cleaning procedures your Insinger dishwasher will give

you years of trouble free service.

2.B.1 Operation Instructions

2.B.1.1 Ensure drain overflow tube is in place Close the tank drain valve.

2.B.1.2 Check for proper installation and cleanliness of all internal, removable

components such as suction strainers, scrap screens, and rotating spray pipes.

2.B.1.3 Ensure all water, and steam, lines are open. Ensure electrical circuits are on.

2.B.1.4 Close machine doors.

2.B.1.5 Move the power toggle switch to the "ON" position. The machine will fill the

tank, run through a complete wash/rinse cycle and shut-off.

2.B.1.6 When the tank is full the tank heat will operate automatically. Proper tank heat

is 150°F.

Caution

To ensure proper operation of the auto tank fill feature and the tank

heaters, level float(s) located in each tank MUST be cleaned daily

2.B.1.7 Open doors.

2.B.1.8 Insert a rack of soiled dishware in machine (two racks for the DA-3) and lower doors.

Machine will wash and rinse automatically. When the rinse indicator light goes off the cycle is

complete.

Note

Overloading racks will minimize the proper cleaning of ware.

Warning

Do not open the doors during the wash/rinse cycle as hot water is being

sprayed. An interlock is provided to stop the wash/rinse cycle if the doors

are opened but the momentum of the spinning hubs will cause hot water to

be sprayed.

OPERATION & CLEANING INSTRUCTIONS

Part 2, Section B

2.B.1.9 Raise doors and remove rack of clean ware. For continuous operation repeat

steps B.1.9 and B.1.10.

2.B.1.10 Upon completion of ware cleaning move the power toggle switch to the "OFF"

position.

2.B.1.11 Refer to the cleaning procedures for proper clean-up of the dishmachine.

2.B.1.12 Report any unusual occurrences to qualified service personnel.

The following cleaning procedures should be done daily, at the end of the shift.

2.B.2 Cleaning Procedures, Daily

2.B.2.1 Remove all internal removeable parts including rotating spray pipes, scrap screens, drain

overflow tubes, suction strainers and curtains.

2.B.2.2 Remove the end caps from the spray manifolds and clean with the brush provided. Flush

the manifolds.

Note

Do not remove wash and rinse spray arms from the hubs as these

are factory set. Cleaning should be done by removing the endcap on

each arm.

2.B.2.3 Flush scrap screens.

2.B.2.4 Clean drain overflow tube.

Note

V-cup seal on the drain overflow tube may become gummed and not

allow the overflow tube to seat properly. This will cause the drain to leak

water. Remove any build-up on the v-seal. When the seal becomes worn,

replace.

2.B.2.5 Clean suction strainers of build-up.

Note

Improper cleaning of suction strainers will cause the pumps to cavitate.

This will cause poor washing results.

3.A.2.7 Motor Overloads

3.A.2.7.1 All motors used on Insinger Machines are provided with motor overloads. Motor

overloads are adjusted when the machines are factory tested. Should it be necessary to

adjust the motor overloads first verify the motor current draw for the voltage the machine is

using.

3.A.2.7.2 Using the Control Panel Component Layout Drawing located in Section 4 to

identify the overload, adjust by turning the dial to the appropriate current draw.

3.A.2.8 Level System
