Control Panels

motor before connecting controls or power supply.
Adhere to local electrical codes governing pump and
control installations.
A control panel is not included with the pump.
Install simplex or duplex control panel (purchase
separately) for proper pump operation. A full range of
controls and switches is listed in our catalog.
If a Myers control panel is not used, install a control
panel with circuit breaker or fused disconnect as
required by local code. Use magnetic starters with
ambient compensated overload protection. Three phase
units require three line protection; single phase units
require only one line protection. Inadequate protection
voids the warranty.
Control Panel Overload Adjustment – Three
Phase
NOTE: See your con trol panel in stallation and operating
instructions before adjusting overload setting.
Set the overload protective device to the nameplate full
load current.
Size the overload protective device so that the trip
current is 115% of the nameplate full load current.
