IN-ECO spol. s r.o.
Check connections of the pipes/hoses for leaks.
Check direction of rotation:
> The direction of flow of the pumped gases/vapors is marked with arrows on the intake and discharge connection.
> The intended direction of shaft rotation is marked with an arrow on the motor mounting adapter between the intake
and discharge connection, as well as with an arrow on the fan guard.
> The pump-motor unit may not be allowed to run dry! Have you filled it with operating liquid
beforehand (during or after installation)?
provozního režimu agregátu:
See sections „Fill with operating liquid“ ,Pg. 17 a Pg. 18.
> Briefly switch on pump-motor unit.
> Compare the actual direction of rotation of the external fan with the intended direction of shaft rotation as indicated
with the arrows.
> Switch off pump-motor unit again.
> If necessary, reverse the direction of rotation of the motor.
WARNING
Danger due to gauge pressure and vacuum!
Danger due to escaping fluid!
Before beginning work on the unit or system:
. Interrupt supply of operating liquid.
. Bleed lines and vacuum pump/compressor (depres-
surize).
DANGER
Electrical danger!
The electrical connection may be carried out by trai-
ned and authorized electricians only!
DANGER
Electrical danger!
Before beginning work on the unit or system, the
following measures must be carried out:
- Deenergize.
- Secure against being switched on again.
- Determine whether deenergized.
- Ground and short-circuit.
- Cover or block off adjacent energized parts.
See Fig. 8, Pg. 20.
Here the following must be watched:
> The pump-motor unit must be pre-throttled on the inlet side. This means a vacuum of at least 900 mbar abs. [13.1
psia] must be present in the inlet pipe (Item B) at switchon.
> During switch-on, the liquid level in the feed pipe (Item A) and in the reservoir (Item C) respectively must be at the
same level as the center of the unit shaft (Item 1).
> During operation the liquid level in the reservoir (Item C) may not drop below approx. 1 m [3.28 ft] below the center
of the unit shaft (Item 1).
Starting the pump-motor unit:
> Switch on the unit.
> The operating liquid is sucked in.
