CAUTION!
Possible environmental and material damage
In event the red gear bleeding plug is sealed, during opera‐
tion it prevents any pressure compensation between the
drive housing and the surroundings. This ensure that oil can
be pushed from the drive housing.
– Remove the gear bleeding plug before commissioning.
Before start up pull the red gearbox vent stopper off, see chapter "Over‐
view of equipment and control elements".
When the pump is idle, check whether the oil level in the pump is in the
middle of the oil level indicator.
This will rule out the pump losing oil and suffering damage.
When commissioning the unit, check whether the drive motor is rotating
correctly - check this against the arrow on the motor housing or the dia‐
gram in the chapter entitled "Electrical Installation."
CAUTION!
Danger due to incorrect use of the integral relief valve
The integral relief valve can only protect the motor and the
gear, and then only against impermissible positive pressure
that is caused by the metering pump itself. It cannot protect
the system against positive pressure.
– Protect the motor and gear of the system against posi‐
tive pressure using other mechanisms.
– Protect the system against illegal positive pressure using
other mechanisms.
CAUTION!
Danger of the integral relief valve failing
The integral relief valve no longer operates reliably with feed
chemicals having a viscosity of greater than 200 mPa s.
– Only use the integral relief valve with feed chemicals
having a viscosity up to 200 mPa s.
1. Hydraulically isolate the discharge line from the pump using an iso‐
lation device.
2. Turn the rotary dial on the integral relief valve in a counter-clockwise
direction as far as the "open" stop.
ð
The excess pressure escapes through the hose connector.
3. Run the pump until the feed chemical coming out of the hose con‐
nector is free from bubbles.
4. Turn the rotary dial on the integral relief valve in a clockwise direc‐
tion up to the "close" stop.
ð
The pump can be started.
