Operation
Do not use this pump to pump liquids.
1. Place the pump in the required location and
connect to the electricity supply.
2. Ensure that the outlet port is not blocked.
Never block the outlet port. If the pump
is run with the outlet blocked pressure
will build up in the pump which can
lead to the pump head bursting.
3. Ensure that the catch pots are empty and in
good condition. (see fig 1).
4. Switch the pump on and allow it to run for
a few minutes in order to warm up before
connection to the vacuum system.
5. Switch off and connect the pump to the
vacuum system.
6. Fully open the vacuum regulator (see fig 1)
by turning it anti-clockwise to the stop.
Note: It is necessary to completely turn the
vacuum regulating valve a number of times
before it is fully open. When fully open the
vacuum regulator will reach a stop point and
won't be able to turn any further, take care not
to force the valve past this point.
7. Switch on the pump.
8. Slowly close the vacuum regulator until the
required vacuum level is shown on the
gauge (see fig 1).
Do not run the pump continuously for more
than 18 hours at blankoff. This will cause
the pump to overheat and seize.
9. After use release the vacuum before
switching off the pump. This can be done
either by venting the vacuum system or fully
opening the pump's vacuum regulator.
10. Switch off the pump and disconnect from
the vacuum system.

11. It is recommended that after use the pump
be switched on again and run while
disconnected from the vacuum system for 2
minutes. The air passing through will purge
any vapours or condensate from the pump
heads and extend the diaphragm life.

Safety Features

For the protection of the user and the pump
there are several safety features included (See fig 1).
1. Inlet Catch Pot
Liquid or particulate matter entering the pump
will cause damage and loss of performance. In
order to prevent this a catch pot is fitted to the
inlet port to trap such material before it can
enter the pump head.
If the pot becomes half full it should be emptied
as follows:
1. Switch off the pump and release the
vacuum
2. Unscrew the catch pot
3. Empty, clean and dry and examine the catch
pot and seals before screwing back into
place
4. Restart the pump.
2. Outlet Catch Pot
If a heavy vapour load is pumped it is possible
for condensation to occur inside the pump
because of the compression. The pump is
designed to cope with this load and will not be
damaged. However the resulting liquid will be
ejected from the outlet port.
The catch pot will collect this liquid preventing it
being ejected into the laboratory.
If the pot becomes half full it should be emptied
using the procedure outlined above for the inlet
pot. The contents of the pot should be disposed
of according to appropriate legislation.
