IT IS IMPORTANT THAT THIS OPERATION IS
ONLY UNDERTAKEN BY A QUALIFIED
ELECTRICIAN
The unit is fitted with an IEC socket on a flying
lead at the rear of the instrument. This lead and
the suitable mains lead should be connected
together BEFORE connection to the mains
supply.
Should the mains lead need replacement a cable
of 1mm
2
of harmonised code H05W-F connected
to an IEC 320 plug should be used.
N.B. The UK mains lead is protected by a 10A
fuse mounted in the plug top.
IF IN DOUBT CONSULT A QUALIFIED
ELECTRICIAN
Safety advice
❖
If the mains supply is interrupted the units
will restart with its current settings on the
restoration of the electricity supply
❖
The pump is protected thermally. If the
thermal protection has been activated the
pump may restart unexpectedly when the
protection resets on cooling.
❖
Before use ensure that the outlet port is not
blocked. Before first use remove the cap fitted
for protection during transit.
❖
When using any equipment under vacuum
ensure adequate protective clothing is worn.
At a minimum this should be eye protection,
gloves and overalls.
❖
Do not operate the pump in an atmosphere
containing flammable or explosive vapours.
❖
Do not lift or carry the pump while it is
switched on or connected to the electricity
supply.
❖
The unit should be carried using the handle
located on the top (see fig 1).
Before use
See figure 1
Before installing and using the pump for the first
time please familiarise yourself with the general
layout and features of the pump.
In particular ensure you have correctly identified
the inlet and outlet ports. These are clearly
labelled on the top of the pump heads.
The on/off switch is located at the front of the
motor. Position (I) is on and position (0) is off.
There are plastic catch pots fitted to both outlet
and inlet ports to collect liquid ejected from the
outlet and prevent liquid ingress through the
inlet. The condition of the catch pots should be
checked before each use for cracks, chips or
signs of corrosion. Replace pots if defects are
found.
The inlet port is fitted with a vacuum gauge.
Pressure can be adjusted via the vacuum
regulator located at the front of the unit.
Installation
1. Choose a clean, dry and well ventilated area
where the pump will not be exposed to
moisture or flammable vapours.
2. The unit should be placed on a firm level
surface.
3. The pump is fitted with 4 rubber feet which
help reduce noise and creeping while the
pump is in use.
4. It is recommended that flexible hose
connections between the pump and the
vacuum system are kept as short as possible.
5. It is recommended that a flexible hose be
attached to the outlet port in order to lead
any fumes which pass through the pump
away from the working area, preferably into a
fume hood. Make sure this hose does not
become kinked and block the outlet path.
6. The tubing connectors on the inlet and outlet
ports accept tubing of 9mm internal diameter.
