4.2.3
Balancers used in drops
Drops have no provision to mount the safety wire.
Instead it can be mounted to the wall or ceiling contruction,
e.g. by means of a mounting plate.
•
Mount the balancer to the drop in question.
•
If desired, attach the safety wire to the wall or ceiling
construction.
CAUTION
Make sure the safety wire connection is strong
enough to hold the weight of the entire
configuration.
4.3
Balancer locking cable
The locking cable's primary function is to control the point of
disconnection.
As the hose reaches it's maximum length the balancer locking
cable will bottom out, in turn pulling the nozzle from the
moving vehicle.
To enable this function it is necessary to cut the locking cable
to the appropriate length by performing the following steps:
•
Extract the nozzle up to 25 cm +/- 5 cm (10 in. +/- 2 in.)
from the door and 50 cm (20 in.) from the ground (tailpipe
height).
•
Measure the shortest distance between the two spring
safety hooks of the balancer.
•
Cut the balancer locking cable using a power cutter and
adjust to the measured distance.
•
Install the balancer locking cable between the two spring
safety hooks.
4.4
Functioning and setting
The balancer is factory-wise delivered with a pre-tension.
It needs to be adjusted to its final tension when the entire
installation is ready. Depending on the installation, there are
two possibilities:
- pre-tension is OK
- spring tension needs to be increased
Check if the balancer is capable of holding and lifting the
connected hose. If not, increase the spring tension as follows:
•
Hold the balancer steady.
•
Turn casing cap max. 0,5 revolutions clockwise (direction
+) using a socket 24 mm
CAUTION
Do not increase spring tension more than 0,5
revolution to avoid serious damage to the balancer.
Except for the BR-200 / 8-17 which can be
increased up to 1 revolution.
