obstructed and that the cooling air flow is not affected adversely in
any other way.
Filling Oil
In case the vacuum pump was treated with conservation oil:
Drain the remainders of conservation oil and top up oil.
The vacuum pump is delivered without oil (oil specification see “Oil” in page
22).
●
According to the description in Oil (Page 22), at least 2L oil shall be kept
in the oil tank (Note: 0.45L oil in 1RV0020, 1L in 1RV0025 and
1RV0040).
NOTE:
The amount given in these operating instructions is a guide. The oil
sight glass (83) indicates the actual amount to be filled in.
Remove the oil fill plug (88)
Filling about 2L oil according to the values set in the table “Oil” (Note:
0.45L oil in 1RV0020, 1L in 1RV0025 and 1RV0040).
Make sure that the level is between the MIN and the MAX-markings
of the oil sight glass (83)
Make sure that the sealing ring (89) is inserted into the oil fill plug (88)
and undamaged, replace if necessary
Firmly reinsert the oil fill plug (88) together with the sealing ring (89)
NOTE
: Starting the vacuum pump with cold oil is made easier when at this
very moment the suction line is neither closed nor covered with a rubber
mat.
Switch on the vacuum pump.
In case the suction line is equipped with a shut-off valve:
Close the shut-off valve
In case the suction line is not equipped with a shut-off valve
：
Cover the suction connection with a rubber mat (260).
Let the vacuum pump run for a few minutes.
Shut down the vacuum pump and wait a few minutes.
Make sure that the level is between the MIN and the MAX-markings
of the oil sight glass (83)
In case the level has fallen below the MIN-marking of the oil sight
glass:
Top-up oil
In case the suction line is equipped with a shut-off valve:
Open the shut-off valve
In case the suction line is not equipped with a shut-off valve:
Remove the rubber mat, and connect the suction connection
Recording of Operational Parameters
As soon as the vacuum pump is operated under normal operating
conditions:
Measure the drive motor current and record it as reference for future
maintenance and troubleshooting work.
Version with exhaust filter pressure gauge
：
Read the scale of the exhaust filter pressure gauge and record it as
reference for future maintenance and troubleshooting work (Check
during operation in Page 11).
Operation Notes
Application
The vacuum pump is designed for the suction of air and other dry,
non-aggressive, non-toxic and non-explosive gases
Conveying media with a higher density than air leads to an increased
thermal and mechanical load on the vacuum pump and is permissible only
after prior consultation with Greenco company.
Max. allowed temperature of the inlet gas, see “Oil, Ambient temperature
range”
In case the vacuum pump is equipped with a gas ballast (optional) water
vapor within the gas flow can be tolerated within certain limits (see
“Installation and Commissioning, Operating Notes, Conveying Condensable
vapors” in Page 8). The conveyance of other vapors shall be agreed upon
with GREENCO.
The vacuum pump is made for the intended use in potentially non-explosive
areas.
If the vacuum pump is equipped with ball-lock valve (200) and oil return
pipe:
CAUTION
The vacuum pump is designed for operation under the conditions
described below.
In case of disregard risk of damage or destruction of the vacuum
pump!
Risk of Injury!
The vacuum pump must be operated under the conditions
described below.
CAUTION
Filling oil through the gas inlet (260) will result in breakage of the
vanes (22) and destruction of the vacuum pump.
Oil may be filled through the oil fill port only (88).
CAUTION
During operation the oil separator is filled with hot, pressurised
oil mist.
Risk of injury from hot oil mist with open oil fill port .
Risk of injury if a loosely inserted oil fill plug (88) is ejected .
Remove the oil fill plug (88) only if the vacuum pump is stopped.
The vacuum pump must only be operated with the oil fill plug (88)
firmly inserted.
CAUTION
The vacuum pump is shipped without oil.
Operation without oil will ruin the vacuum pump in short time.
Prior to commissioning it must be made positively sure that oil is
filled in.
