Tubing Connectors
All models
There are 6 tubing connectors in back of the washer. One
connector is larger in diameter than the others. The larger
diameter connector should be used for the pump requiring the
highest flow rate. If you need additional chemicals, contact the
manufacturer. Tubing connectors are sealed at the factory
and must be drilled out before use.
NOTES:
Only drill out connectors that will be used. Any unused
open connectors must be sealed to avoid reflux during
the fill cycle.
Holes must be drilled. Attempting to open holes with a punch
will damage the washer.
1.
Drill out connectors that will be used. Use a drill bit slightly
smaller than the interior diameter of the hole. Remove all
debris from the hole. See illustration.
2.
Attach flexible hoses rated for commercial laundry chemicals
to the connectors. (Secure the hoses with a hose clamp.)
PD models only
These additional steps are necessary to connect tubing
connectors:
3.
Open top cover. Locate
connectors that were drilled.
Attach tightly fitting flexible
hoses rated for commercial
laundry chemicals onto those
connectors long enough to
reach the dispenser
connectors. Secure with
a hose clamp.
4.
Be sure that dispenser connectors fit the hoses. Drill out
connectors on the dispenser with a drill bit slightly smaller
than the interior diameter of the hole. Remove all debris from
the hole.
5.
Attach flexible hoses rated for commercial laundry chemicals
to the connectors. Secure the hoses with a hose clamp.
