operation must be performed with pump stopped. Do not over-

the fill plug.
2 Mechanlcal Connections
Mounting on a Frame
The pump can be mounted on a frame by using the 4 mounting
holes in base (3) and 4 special shock mounts (see§ 3.4.3).
NOTES : These mounts reduce the p ump vibrations but will not
hold the pump securely when the pumping assembly is moved.
Clamp pump to frame before moving.
b) Ventilation
The pump and motor are equipped with a ventilation system.
When the pump is installed, the pump should be p laced in a venti­
lated location.
Check ventilation holes on the pump and motor periodically for
obstructions.
Alcatel pumps are designed to operate at an ambient tempera­
ture of 1 O to 40 ° C. If the temperature is likely to rise above
40 C, an auxiliary cooling device can be used (see § 3.4.3).
°
c) Inlet and Exhaust Ports
The pump inlet and exhaust ports are equipped with ISO NW 40
nipples for Pneurop quick connectors to accept various stainless
steel, plastic, etc. tubing accessories (see diagram 6).

In g eneral , use accessories whose ti g htness and materials are
com p atible with the p umped g ases at both the inlet and exhaust.
At the p um p exhaust , the dischar g e circuit must be such that the
resulting overpressure lo the oil case is less than or eq ual to 0.5 bar
relative p ressure.

3.4.4 Electrical connection

It is recommended that the motor be p rotected for1200/oof its rated
current.
In the case of series motors , see the dia g ram "Protection 0f Eleetrt­
cal Motors ( dia g ram 3 ) .
Three-Phase Version
Connect motor accordin g to line volta g e. The connections are
shown on the schematic located inside the terminal box or on the lid.
The pum p s are delivered with their motors connected to maximum
volta g e. Switch on current briefl y to check motor rotation direction.
The end of the shaft must rotate in the direction of the arrow on the
motor mountin g p late (103) .
Function
• separates oil droplets and conta-
minant part i c l es
In exhausted
gases from the machanical va-
cuum pumps.
• in addition to standard oi l mist eli-
minator functions, polluted
and settlings can't turn back into
the pump.
• prevents dust particles larger than
.2 microns from accumulating in
the pump and oil.
• protects pump against conden-
sable vapors.
• prevents oil from backstreaming
into pumped chamber.
• prevents oil backstreaming when
pumping a "clean vacuum".
• facilitates pumping condensable
vapors, regenerates pump oil, by
remote control.
• filters oil when pumping corrosi e
gases containing particles
could rapidly degrade ,oil quality.
• filters oil during p um p in g in a pp li-
cations with high levels of particu-
late.
• when operating at ambient tern-
p eratures above 40 ° C, a water
cool i ng ring can be fitted.
• a l lows pump to
be mounted on
a frame.
• condenses water or solvent
pors before the y enter the mecha-
nical p ump.
