Installation Tips
If you are planning a repair or replacement, keep the following workflow in mind:
- Recommended Pairing: Experienced technicians recommend replacing the 77707-0120 Manifold/Tube O-Ring Kit at the same time as the old o-rings must be disturbed to access the bypass valve. Always make sure to properly lubricate the new o-rings.
- Safety First: Before beginning, ensure the entire pool system is shut down, electrical power is disconnected at the main breaker, and the heater is completely drained by removing the lower manifold drain plug.
