8.9.2 Fitting a low level float switch
1. If the pump is filled with lubricant this must be
removed first. Place a clean tray (A) under the
drain plug in the bottom of the pump. Remove
the drain plug (B). Catch the lubricant from the
pump housing in the tray. Check the sealing ring
(C) for damage.
2. Fit the crimp connector (A) together with the
sealing ring (B) to the pump housing. Fit the
low-level float switch (C) to the crimp connector
(A).
3. Connect the low-level float switch to the
electrical supply. Bear in mind that the electrical
contact of the float switch is normally closed
(NC). When the lubricant level is (too) low the
contact will open.
4. Refill the pump housing to the proper level with
Bredel Genuine Hose Lubricant.
