Installation and
start-up
All series
• After 3 months storage without oil, factors such as temperature, degree of humidity,
salt air, etc. may cause the deterioration of the pump components, particularly the
hardening of O-rings and the "sticking" of lip seals on shafts and the gumming of oil.
In this state, a pump may have operational problems, particularly oil leaks. Before any
start-up (new pump as well as used), the pump must be disassembled (see page 46),
and all the seals changed.
Pump which have been used:
If the pump is not new, drain and rinse it (see page 42). Fill it with new oil, then pump
a dry inert gas through it to remove all traces of dampness in the pumping system and
oil casing. Pump in dry inert gas as fallows:
- 10 minutes at above 2.25 Torr (30 mbar).
- 10 minutes at ultimate pressure with gas ballast open.
- 10 minutes at ultimate pressure.
Stop the pump and seal the inlet and exhaust orifices tightly with quick connect
clamps, centering rings, blank-off flanges...
Note:
The seal kits must be stored with caution. Keep them away from heat and light
(sunlight and ultraviolet light) in order to prevent the elostomers from hardening
(AFNOR standard FD T 46.022).
Storage (cont’d)
The pump must be operated in the horizontal position with the pumping
axis vertical and the inlet operating upwards.
Ensure that the product is connected to an electrical installation:
- in compliance with the local and national safety requirements,
- equipped with electrical protection (fuses, circuit breaker, …) which has a
suitable earth (ground) point, properly connected.
Do not expose any part of the human body to vacuum.
The product is supplied with the inlet and exhaust sealed. Remove these
blanking plates when you are ready to connect the product on your
vacuum system.
As well as, don’t operate the product unless the inlet and exhaust are
connected to a vacuum and exhaust pumping line.
The products are designed to avoid subjecting users to heat hazards.
Specific operating conditions can nevertheless exist that require extra
caution from users due to the high temperatures generated (outer
surfaces > 70° C):
Wear protective gloves to work on the appliance, especially during
maintenance.
Our pumps are tested in the factory with A120 oil or A119 for the USA (A113 oil for
the C2 series).
It is recommended to use the same oil during operation, because the oils are
not mixable (refer to table page 17 and remplacement fluids page 18).
• If changing the type of oil, refer to the chapter concerned for the procedure and the
type of lubricant required (see page 42).
