accessible by anyone operating or servicing the machine. The line from the main shutoff to the
machine should be watertight flex conduit. The factory strongly recommends that a few extra feet be
used to allow the machine to be moved if necessary. The wire used to supply the machine must be
heavy enough to carry the amperage load of the machine.
The first connection should be the main ground to the grounding lug at the lower right hand corner of
the control panel. Next the hookup can be made to the main power block. On 230 VAC machines the
wild leg must be connected to the center terminal.
Once the hookup is complete the circuit breakers in the control box of the washer must be checked to
make sure they are in the "OFF" position. The main switch on the wall can then be turned on to power
the machine.
Step 8 GAS CONNECTION (Gas models only): A certified gas technician is required for the hookup
and final adjustments of the burners. This is necessary to insure proper inlet and manifold pressure for
the gas machines (see page 6 for gas pressure settings).
Verify the type of gas supply to be used, either natural or LP, and make sure the marking on the gas
data plate agrees with that of the supply. The gas line hookup must be made with a union at the
location shown on page 26 (see page 6 for gas line size). This line must have a shutoff valve (supplied
by the customer) installed near the machine and accessible by anyone operating or servicing the
machine.
A stainless steel gas chimney runs up the backside of the machine (see page 6 for size of chimney). A
draft diverter is included with the machine (shipped inside the machine with the other accessories). The
draft diverter must be installed on top of the factory installed chimney. The Type B gas flue can then
be continued to the outside of the building per local codes.
The initial startup of the burners should not be done until the startup procedures for the machine on the
following pages have been completed.
Step 9 STEAM HOOKUP (Steam models only): A steam line is required to supply the steam injector or
recirculated steam heat exchanger coil (see page 6 for size of steam line). A strainer is already built
into the machine but a union will be required in the supply line (supplied by the customer). The
Specification sheet on page 6 lists the rated pressure and average steam consumption rate for the
machine.
