Cleaning:
Each day before using the press, check the pump fi lter bowl
for water. To drain the bowl, ensure the pump is turned off, then simply
unscrew the bowl, dump the water out and re-attach the bowl. If the
press is used for mounting on foam board, the water trap may have
to be emptied quite frequently. Do not allow the bowl to become full,
as this may allow water to enter the vacuum pump and cause serious
damage.
Use a brush or vacuum to remove dust and debris from the rubber
diaphragm as needed. Keeping the diaphragm clean will help prevent
the pump fi lter from becoming blocked.
Clean all the way around the grey silicone seal with a damp cloth,
checking for foreign matter and cuts.
If any adhesive has accumulated on the glass, it may be dissolved
with acetone or nail polish remover. Do not use abrasive cleaners.
A single-edged razor blade may also be used, but be careful not to
scratch the glass.
The outside of the press may be cleaned with any standard, non-
abrasive household cleaner.
Latch Adjustment:
The latches on the front of the unit should close
easily with a comfortable “click”. If they are too loose or if they
need excessive pressure to close, they can be adjusted by turning
the latch on the pivoting, threaded shaft. Adjust only one turn at a
time. Lengthening the amount of threaded shaft visible (by turning
counterclockwise) will tighten the latch and shortening the amount (by
turning clockwise) will loosen it.
Overtightening the latches will not improve the effectiveness of the
vacuum seal and will cause the latches to wear out prematurely.
Hinge Adjustment:
The hinges at the rear of the press are designed
so that they can be easily adjusted to ensure a good vacuum seal.
Make sure that both hinges are adjusted by the same amount to keep
the press lid level.
The top part of the hinge is bolted to the top frame and cannot be
moved. Adjustment is carried out on the bottom part of the hinge. Both
bolts pass through elongated holes in the frame. Should it become
apparent that the grey sealing gasket is not in contact with the
underside of the lid across the entire back of the press, the adjustment
procedure is as follows:
Close the press; loosen both Bolts “A” half of a turn. Turn on the
vacuum pump. Using a wrench, turn Bolt “B” on each hinge a little at a
time until a vacuum is pulled. Only a small adjustment will be required.
Re-tighten both Bolts “A”.
Vacuum Pump:
The vacuum pump is built with sealed, permanently
lubricated bearings and does not require lubrication or other periodic
maintenance other than cleaning the fi lter & water trap.
