Caution!
Work on electric facilities implies danger to life!
6.5 Commissioning
The pump unit‘s functionality has been checked in the factory. Hence, it is ready for
operation and can be connected to a local voltage supply.
Important: Note the safety instructions contained in the "Power supply and
switch-on" section.
First fill lubricant and then start the pump unit, in every case
(Minimum filling level, see chapter 7.2)
Commissioning procedure:
a) Filling the pump with lubricant
The pump units may be operated with clean oil or grease from original
packages only!
The initial filling with grease must be done through the filler nipple in order to
fill the pump’s suction chamber safely.
Hint: For the pump’s initial filling with grease, we recommend to fill it with
transmission oil up to the stirring wing in order to ensure a speedy and
better bleeding.
When selecting the transmission oil, however, proper compatibility
with the lubricant used needs to be ensured.
b) Bleeding the pump unit
The pump needs to be switched on until the lubricant leaves the pump elements‘ outlets free
of air.
c) Connecting lube lines
The lube point lines must be clean and free of any obstruction.
Connect the outlets of the pump elements with the lube lines. These lines must be clean
and free of any obstruction. You may not connect the lube lines to the lube points unless
the lubricant comes out free of air. Check all connections of the lube lines for tightness and
the lube points for air-free lubricant release.
