3.2.4 Pipe connection
Fit the outlet pipe or hose in the Rp 1 1/4 outlet. Steel pipes can be
screwed directly into the pump outlet.
In a permanent installation, fit a union to the outlet pipe to facilitate
mounting and removal. If a hose is used, fit a hose union.
In a permanent installation with a level switch, fit a non-return valve
to the outlet pipe or hose.
3.2.5 Start and stop levels
UNILIFT KP-A
For pumps supplied with a float switch, the difference in level
between start and stop can be adjusted by changing the free cable
length between the float switch and the pump handle.
•
An increased free cable length will result in fewer starts and
stops and a large difference in level.
• A reduced free cable length will result in more frequent starts
and stops and a small difference in level.
The stop level must be above the pump inlet to prevent the pump
from taking in air.
