Operation
Preliminary
precautions
At start-up
, before switching on the motor, check that the oil bath temperature is
greater than 53°F (12°C).
The ambient operating temperature
for the pump must be between 53°F (12°C)
and 113°F (45°C).
Under these conditions,
the stabilized pump temperature
(at the front of the oil
case) will be between 140°F and 158°F (60 and 70°C) (with A120 oil, depending on
operating conditions).
Special case - Synthetic oils
Synthetic oils are much more viscous when cold than mineral oils.
Do not start up the pump at ambient temperatures below 59°F (15°C).
The stabilized temperature is higher than with a pump used with mineral oil.
For the same reason and to facilitate lubrication of the pump, pour a few drops of oil
(1 to 2 cm
3
) through the inlet orifice before starting.
Operating
temperature
The performance and operational safety of this product are guaranteed
provided it is used normally in the operating conditions defined in this
manual.
It is the customer’s task to:
- train operators to use the product if they do not speak the language the
manual is written in,
- ensure operators know the safe practices to apply when using the
product.
Fire protection.
The roughing pump is not intented to be installed on process containing
flammable materials or in hazardous atmosphere.
Fire hazard due to the presence of electrical components.
The fire hazard is low due to the use of appropriated components and the
containment in the pump cover.
The vacuum pump is also a compressor: incorrect use may be dangerous.
Study the user’s manual before starting up the pump.
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.
The products are factory tested to ensure they will not leak in normal
operating conditions. It is the user’s responsibility to
ensure this level of leak tightness is maintained.»
For emergencies and breakdowns, contact the manager of your local
service center (see addresses at back of manual).
