Float Switch Installation
Pass the float switch lead through the tank/cable
gland assembly to give the desired alarm switchpoint
and tighten the cable gland.
Fit the float switch assembly through the 1" BSP
tank gland in the tank.
Should the float switch lead require extension, fit a
PVKA extension cable connector to the float switch
lead and run the length of additional cable from the
PKVA connector to the TA3 unit.
