Installation Notes
Shut off power to the spa system and lock out the circuit. Remove the existing blower, noting mounting orientation, air plumbing size, and electrical connections. Install the new 6315141 blower in the same orientation, connect the outlet to 2″ slip air plumbing, wire to correct voltage, and ensure proper ventilation around the motor housing. Restore power and verify the blower generates consistent air flow with minimal noise.
Maintenance Tip
Inspect the blower annually: check mounting bolts, clean any debris around the intake, ensure the spring-check valve moves freely, and listen for changes in noise or vibration. Replace the blower if you observe abnormal sound, decreased airflow or signs of motor overheating to maintain spa performance and longevity.
