Conservation
In case of adverse ambient conditions (e.g. aggressive atmosphere,
frequent temperature changes) conserve the vacuum pump immediately. In
case of favorable ambient conditions conserve the vacuum pump if a
storage of more than 3 months is scheduled.
During the factory tests, the vacuum pump inside has been completely in
contact with oil. In case of favorable ambient conditions, it is not necessary
to the pump with conservation oil. In case of unfavorable storage conditions,
the vacuum pump draining with conservation oil is advised. If anything
remains to be clarified please contact your Greenco representative!

(or a conservation oil from same quality)
NOTE:
VCI stands for “Volatile Corrosion Inhibitor”. VCI-products (film,
paper, cardboard, foam) evaporate a substance that condenses in
molecular thickness on the packed good and by its electro-chemical
properties effectively suppresses corrosion on metallic surfaces. However,
VCI-products may attack the surfaces of plastics and elastomers. Seek
advice from your local packaging dealer! GREENCO uses CORTEC VCI
126 R film for the overseas packaging of large equipment.
Wrap the vacuum pump in VCI film.
Store the vacuum pump.

Commissioning after conservation
Make sure that the gasket, plug or adhesive tape are removed from the
ports.
Commission the vacuum pump as described in the chapter “Installation
and Commissioning” (Page 5).
Installation and Commissioning
Installation prerequisites
Make sure that the assembly of the vacuum pump is carried out in line
with the essential safety requirements.
Mounting Position and space
Make sure that the environment of the vacuum pump is not potentially
explosive.
Make sure that the following ambient conditions will be complied
with
：
—
Ambient temperature: see “Oil”
If the vacuum pump is installed in a environment of low temperature:
—
Ambient pressure: atmospheric pressure
Fit the vacuum pump either with an oil sump heater (on request) or
fit the vacuum pump with a temperature switch and control the vacuum
pump in such a way that it will start automatically when the oil sump
CAUTION
Tilting a vacuum pump that is already filled with oil can cause large
quantities of oil to ingress into the cylinder.
Starting the vacuum pump with excessive quantities of oil in the
cylinder will immediately break the vanes and ruin the vacuum
pump.
Once the vacuum pump is filled with oil it shall not be lifted
anymore.
CAUTION
In case of non-compliance with the installation prerequisites,
particularly in case of insufficient cooling:
Risk of damage or destruction of the vacuum pump and adjoining
plant components!
Risk of injury!
The installation prerequisites must be complied with.
