Installation Notes
Shut off power and lock out the circuit before servicing. Remove the pump housing and old motor, confirm mounting and shaft alignment match, install the new HSQ125 motor, wire per voltage label, secure pump and motor assembly, restore power and verify correct rotation, amp draw and smooth operation.
Maintenance Tip
Inspect motor bearings for noise or vibration annually, check mounting bolts for tightness, and verify current draw remains within spec. Replace the motor if amps increase, flow falls or lubrication/ventilation issues appear to maintain pump performance and prolong service life.
