ST-1500 SERIES SUB. PUMP— CONTROL BOX INSTALLATION

DANGER

The ST-1500 series submersible pumps are also designed to work with a control box (Model CB3).This control box contains the necessary

electronics (float switch connections) to operate the pump. Remember this control box contains hazardous voltages. Disconnect all sources of power before installing or servicing. There exists the possibility of electrocution, electric shock or burn, which can cause severe bodily harm or even death!

CAUTION

This control box should only be installed or serviced by a licensed electrician or qualified personnel.

Control Box Mounting

Mount thecontrol box in anupright vertical position.Makesure the control box is securely fastened to a flat surface, that is free of dust, dirt, moisture or any elements that may contaminate or erode the electronic components of the control box.

Single-Phase Power Installation (Input)

All ST-1500 series submersible pumps require 115 V, 60 Hz., single-phase power for normal operation.

If you cannot determine what your pump's power requirements are, look at the vendor supplied identification name tag attached to the pump or please contact Multiquip's Service/Technical Assistance department.

CAUTION

Applying incorrect power (voltage phasing) to the submersible pump can cause severe damage to the pump. Please make sure that the correct voltage and phase are transferred to the pump at all times.

Power Cord Requirements

When routing the 115 VAC, 60 Hz., single phase power via a power cord to the control box, ALWAYS use the correct wire size. Please reference Table 4 below (Cord Length/Wire Size) to determine the correct wire size. Incorrect wire size can adversely affect the performance of the pump.

2.Tighten the connector housing to ensure a tight fit between the cord and the connector body.This will prevent the cable from pulling out of the terminal block and also prevent moisture from entering the control box.

3.Determine the length of the float switch wires, then secure float switch wires to pump discharge hose. See Figures 3 and 6 and Table 3 to determine the pumping range.
