– Note: We recommend warming up the hose with hot water, pushing it or
twisting it onto the hose adapter and securing with the appropriate hose
clamp. This improves the seal of the connection.
– To avoid pressure loss, saw off the stepped hose adapter at the
appropriate point for the respective hose.
Note: At the end of each step of the hose adapter there is groove for
shortening (see arrow in the fig.).
– Avoid unnecessary angles and curves that lead to additional pressure
loss.
7.3.1 Water intake D
To ensure proper cleaning rotor function, the flow nozzle must be inserted in
the intake duct if there is low water flow and/or a large height differential
between pond surface and the Bitron's water discharge (see Table 8 and
Fig. 6).
Legend for Table 8 (page 47):
X Flow nozzle must be inserted.
– Flow nozzle not required.
Due to the excessively low water flow, the cleaning rotor will no
longer function even with flow nozzle inserted.
1. To avoid pressure loss, saw off the stepped hose adapter at the
appropriate point for the respective hose.
– Bitron 18C/24C: Stepped hose adapter 1" to 1½"
– Bitron 36C/55C: Stepped hose adapter ¾" to 2"
2. Insert the flow nozzle in the water intake – if required according to Table 8.
The triangular protrusion in water intake D fits into a corresponding
aperture in the flow nozzle.
3. Push the threaded collar over the stepped hose adapter.
4. Push or twist the hose on and secure it with a suitable hose clamp.
5. Insert the flat gasket in the threaded collar. Firmly screw the stepped
hose adapter with threaded collar onto the water intake D of the UVC
device.
6. Layout the hose all the way to the pump in such a manner that it cannot
be stepped on and has no kinks.
7. Connect the hose to the pump according to the pump's operating
instructions.
7.3.2 Water discharge A and C (only for single-unit setup)
1. To avoid pressure loss, saw off the stepped hose adapter at the
appropriate point for the respective hose.
2. Push the threaded collar over the stepped hose adapter.
3. Push or twist the hose on and secure it with a suitable hose clamp.
4. Insert the flat gasket in the threaded collar. Firmly screw the stepped
hose adapter with threaded collar onto the water discharge A and C of
the UVC device.
