in Figure 4.
2. Loose a screw, cord clamp and float cord band on the
float switch
3. Shift the float cord band to the required cord tether
length ,then tighten the screw, cord clamp and float
cord band.
SINGLE-PHASE POWER INSTALLATION (INPUT)
1. All submersible pumps referred to in this manual
require 115 VAC, 60 Hz., single-phase power for
normal operation.
2. If you cannot determine what your pump's power
requirements are, look at the vendor supplied
identification name tag attached to the pump or contact
Multiquip's Technical Support Department.
CAUTION
When Installing the float switch, keep enough space
around the float switch to avoid an improper operation.
POWER CORD REQUIREMENTS
When routing the 115 VAC, 60 Hz., single phase power via
a power cord ,
ALWAYS use the correct wire size. Refer to
Table 3 to determine the correct wire size. Incorrect wire
size can adversely affect the performance of the pump.
CAUTION
Applying incorrect power (voltage phasing) to the
submersible pump can cause severe damage to the
pump.
Make sure that the correct voltage and phase are
transferred to the pump at all times.
