MAINTENANCE
Thorough flushing and proper maintenance are
essential
to keep your
system working properly
.
Improper flushing or maintenance may prevent the
system from working the next time you need it, and
may
result in costly damage to the system.
Always
flush your system thoroughly and
immediate
-
ly
after each use.
Always
drain all water out of the roller
valve and ex
-
tension
and leave the system filled
with mineral spir
-
its
to prevent corrosion.
CAUTION
NOTE: A
Garden Hose Flush Adapter
, P/N 220–231, is
included.
This adapter is placed at the pump inlet
and uses a standard city water supply to aid in
flushing. Instructions on how to use it are in-
cluded
with the adapter
.
Flushing Procedure (Latex Paint Only)
1. T
urn the ON/OFF switch to OFF
.
2. Trigger the roller valve and roll out the excess paint
from
the roller onto a wall or newspaper
. Remove
the
roller cover and dif fuser, and soak these parts in a
pail
of warm, soapy water
.
3. Put the suction tube in a pail of warm, soapy water.
Hold the roller frame over the paint pail, turn on the
system,
and trigger the
roller valve
to drain and save
the
paint
in the hoses. See Fig 3. Release the trigger
and shut of f the pump as soon as all the paint is
drained.
This avoids contaminating the
paint
with
the
flushing
water
.
4. Now
hold the
roller frame
over the flushing pail. T
urn
on
the pump and trigger
the
roller valve
. Circulate the
solution
for three to five minutes (five
to ten minutes
if using a cold solution). Open the priming valve for
a few seconds to clean the priming tube. Close the
priming
valve.
5. Raise
the suction hose above the water and run
the
pump
for a few seconds
to drain the flushing solution.
Shut
of
f the pump.
6. Wash off all external parts of the hoses, extension,
roller frame,
roller valve
and pump.
7. Flush
again with clean, clear water
. Change the wa
-
ter as necessary , until the system is thoroughly
cleaned.
8. Finally,
flush
the system with clean mineral spirits for
just
a few seconds. Open
the priming valve and turn
off
the pump. Some mineral spirits
must be left in the
system
to prevent corrosion.
CAUTION
Never
leave
water or water-based
paint
(latex) in the
system. To prevent corrosion in the pump, exten-
sion, roller valve and roller frame, your final flush
must
be with mineral spirits.
9. Thoroughly rinse the roller cover inside and out.
Clean
the dif
fuser as explained on page 9.
10. Oil
