5. OPERATING INSTRUCTIONS
5.1 BEFORE STARTING
5.1.1 Read this Handbook carefully.
5.1.2 Level the unit and jack or chock to
prevent movement in use.
5.1.3 Check the engine fuel and
lubricating oil levels. Top up as
necessary.
5.1.4 If mechanical seals are fitted check
the reservoir coolant or lubricant
level.
5.1.5 Check the vacuum pump drive belt
is correctly tensioned.
5.1.6 Hand start engines:- Check that
the starting handle is serviceable.
Electric start engines:- Ensure that the
batteries are charged and ready for
use.
5.1.7 Radiator cooled engines:- Check
the coolant level and that the
radiator is free from any debris.
Note that these units are fitted with
‘puller’ fans and therefore it is the
external face of the radiator which
may become blocked.
Air cooled engines:- Check that air inlets
are unobstructed and that the
cylinder vanes are free from debris.
5.1.8 AC50, AC75, AC80 & AC100:-
Check oil levels in vacuum pump
reservoirs.
Other units:- Draw off any water from the
vacuum pump coalescer oil sump
via the tap in the side. Check the oil
level which should be level with the
underside of the cap.
5.1.9 Check that the discharge non return
valve is seating properly and that
there is no debris in the ball
chamber that may prevent correct
operation.
5.1.10 Select and fit a suitable strainer for
the job in hand. Note that most ‘off
the shelf’ strainers are for general
purpose use. As such they may not
protect the pump against oversize
solids. For applications where
stones, etc., may be drawn in, then
a strainer with holes slightly smaller
than the pump handling capacity
must be employed. Refer to the
Technical Data section for details
on specific pumps.
5.1.11 Connect suction and delivery hoses
making sure that there are no sharp
bends in the lines. Where the
hoses pass over sharp edges or
abrasive surfaces ensure that they
are protected by suitable means to
prevent chafing. Ensure that the
suction
hose end is fully
submerged.
5.1.12 AC50 & AC75: Ensure that the mini
ball valve connecting the suction
line to the top cover of the pump is
in the open position (screwdriver
slot aligns with the axis of the
body).
Other units: Check that the surge control
valve is fully screwed in. This is the
large indented nut surrounding the
surge control valve knob on the top
of the priming tank.
