Installing / retrofitting a check valve (option)
The BPV check valve (see chapter 6 R
EPLACEMENT
PARTS
AND
ACCESSORIES
) is available as an accessory. It prevents the test sample
from rising through the cleaning nozzles into the hose system due to
hydrostatic pressure. It is especially recommended with immersion
depths of more than 1 m and can be retrofitted at any time.
The check valve is mounted into the length of tubing on the pressure
side in the enclosure of the Cleaning Air Box. To do so, proceed as
follows:
Warning
Risk of injury by rotating parts inside the enclosure.
While the pump is running there is risk of injury for the fingers and
risk of hair and loose clothing being drawn in at the blower wheel.
Before opening the enclosure, disconnect the Cleaning Air Box
from the power supply and secure it against being switched on
inadvertently.
Warning
Mortal danger due to live electrical wires inside the enclosure.
Before opening the enclosure, disconnect the
Cleaning Air Box from the power supply and secure it against
being switched on inadvertently.

Connect all wires to the terminal strip. While doing so, pay
attention to the specifications on the label located on the right
side of the terminal strip.
