Fitting a high and low-level float switch
1. If the pump is filled with lubricant this must be removed first.
Note: The drain plug is in the cover of the pump.
2. Place a tray (A) under the drain plug. The tray must be large enough to contain the lubricant,
possibly contaminated with product fluid, from the pumphead. Remove the drain plug (B).
Collect the lubricant from the pump housing in the tray.
3. Position the drain plug and tighten it to the specified torque.
4. Dismount the plugs (A) and (B) on the rear of the pumphead.
5. Position the quick couplings (C) and (D) in both openings.
6. Clamp both connection tubes (E) and (F) on the riser pipe (G) and the quick links (C, D).
7. Connect the high and low level float switch to the electrical supply. Bear in mind that the
electrical contact of the float switch is normally closed (NC). This means that:
• the contact of the high level float switch opens at a (too) high lubricant level
• the contact of the low level float switch opens at a (too) low lubricant level
8. Make sure the lubricant returns to the prescribed level.
