sides of the machine.
A.1.2 Set unit in place and adjust the feet to level the machine.
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.
A.2 ELECTRICAL CONNECTIONS
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.
A.2.2 A single-point electrical connection is provided for the pumps, control circuit, and wash tank heater.
A.2.3 If an electric water booster is provided connect the power directly to the booster. If the Insinger Self -Contained

for each tank.
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.

In order to insure the proper operation of your INSINGER dishwasher, it is necessary that the
LIQUID LEVEL FLOAT be wiped free of any residue and/or moisture at each cleaning. This should be done,
preferably, after each use of the machine, or, at a minimum, once each day.
The LIQUID LEVEL FLOAT is located below the scrap screens is those tanks which contain water
heating devices (coils, steam injectors, or electric immersion heaters) and pump inlet strainers. They are
usually located, in rackless and rack conveyor style machines , on the inside tank wall, at approximtely water
level, opposite and parallel to the inspection doors. In the door, stationary rack, type machines, the LIQUID
LEVEL FLOAT may be found beneath the scrap screen.
Below is a depiction of the LIQUID LEVEL FLOAT and the surfaces which must be wiped clean.

(SEE GENERAL ARRANGEMENT DWG. FOR COMPONENT LOCATIONS)
Hot Surface Ignition Module -
24 VAC, 4 second heat-up time, 7 second trial for ignition. Loss of flame will result in
one re-try for ignition. This unit cannot be repaired - it must be replaced. Flame current .75
micro amp minimum.
Gas Valve -
This valve is equipped with a redundant solenoid valve, that controls gas flow to the pilot and
main burners, a relay -operated main valve that controls gas flow to the main burner, a pressure
regulator to maintain a constant outlet pressure, and a two-position gas cock knob for manual gas
shut-off. Both redundant and main valves open together due to the jumper wire installed between
terminals M-1 and P-3.
The gas outlet pressure is stamped on a metal nameplate inside the burner box. This should
be checked using a manometer at the pressure tap on the outlet of the valve. Remove 1/8" pipe plug
with an allen wrench (not brass hex fitting) to install test fitting.
The gas supply to the valve can be checked using a manometer at the pressure tap on the
inlet of the valve. Shut off gas downstream before removing 1/8" pipe plug to install test fitting.
Hot Surface Element (Ignitor) -
This consists of a silicon carbide heater blade cemented into a ceramic holder with a metal
mounting plate mechanically attached. The ceramic extends 3/4" past the mounting plate into the
burner. The wide surface of the blade must face the burner surface.
To check operation, shut off gas supply. The glow of the ignitor during the heat -up and trialfor-ignition periods can be seen through the viewport (look up from ground level). If no glow can be
seen, a cracked blade or or bad blade to wire joint is possible. Disconnect wire leads and measure
resistance at room temperature (1 to 6 ohms) .
