Inspect strainer and clean if
necessary.
Open valve in condensate
return line.
Reduce amount of time set on
steam timer.
Check steam line installation to
see that "risers" are installed,
as shown on installation
illustration.
Install a by-pass trap from
supply header to by-pass
condensate to return line.
Install a separate trap for each
machine.
Inspect all traps to see if one is
stuck open, or improperly
installed. Perform steps neces-
sary to make return line drain
by gravity to condensate return
tank. See that return tank is
adequately vented.
See wet steam above.
Inspect machine and repair or
replace any leaking parts.
See leaking steam valve (3).
Inspect wheel and remove any
foreign objects & lint.
Inspect wheel for loose balance
weights, out of round or dam-
age, replace if necessary.
Inspect motor to see if bearings
are tight and motor free
turning. Replace motor if
necessary.
Inspect motor mount to see if
machine has been dropped in
transit, bending the mount,
letting the blower wheel hit the
housing. If so, inspect blower
wheel for damage. Replace
either or both if necessary.
Check to see that wheel is
mounted in center of housing,
key is in keyway if used, and
both set screws tight.
Check electrical service and be
sure main switch is "ON" all
wires are tight and fuses are
good.
