The Presscontrol tted to this pump has a status indicator light mounted
on its front panel. This light will be illuminated whenever the Presscontrol
senses that there is electrical power available. The light will only work
when unit is connected to the correct electrical supply.
The electrical connections and checks must be made by a qualied
electrician and comply with applicable local standards.
NOTE: For protection, the Davey pump motors are tted with an automatic
reset thermal overload, constant tripping of this overload indicates a
problem e.g. low voltage at pump, excessive temperature (above 50°C) in
pump enclosure.
