4. Setup and Installation
Installation should only be performed by a qualified service technician or electrician. Ensure all power to the spa is disconnected before beginning.
- Power Disconnection: Turn off the main power breaker to the spa or hot tub at the service panel. Verify power is off using a voltage tester.
- Drain Spa: Drain the spa water to below the level of the heater.
- Remove Old Heater (if applicable): Disconnect plumbing unions and electrical connections from the existing heater. Carefully remove the old unit.
- Install New Heater:
- Ensure new O-rings are properly seated in the plumbing unions.
- Connect the new Balboa VS100 FloThru Heater into the plumbing lines, tightening the union nuts securely by hand, then with a wrench for a snug fit (do not overtighten).
- Connect the heater's electrical wires to the spa pack's heater terminals according to the spa pack manufacturer's wiring diagram. This typically involves two hot wires (L1, L2) and a ground wire.
- Connect the temperature sensor wires to the designated sensor ports on the spa pack.
- Refill Spa: Refill the spa with water, ensuring the heater is completely submerged and there are no air pockets in the plumbing system.
- Check for Leaks: Inspect all plumbing connections for leaks before restoring power.
- Restore Power: Once all connections are secure and leak-free, restore power to the spa at the main breaker.
5. Operating Instructions
The Balboa VS100 FloThru Heater operates in conjunction with your spa's control system. Once installed and powered, the heater will activate automatically when the spa's control system detects that the water temperature is below the set point and there is adequate water flow.
- Temperature Setting: Adjust the desired water temperature using your spa's main control panel. The heater will work to maintain this temperature.
- Flow Requirement: The heater requires sufficient water flow to operate. Ensure your spa pump is running and filters are clean to maintain proper flow.
- Indicator Lights: Refer to your spa's control panel manual for specific heater indicator lights or messages.
6. Maintenance
Regular maintenance ensures the longevity and efficiency of your heater.
- Water Chemistry: Maintain proper spa water chemistry (pH, alkalinity, calcium hardness) as recommended by your spa manufacturer. Imbalanced water can lead to scale buildup or corrosion, damaging the heating element.
- Flow Inspection: Periodically check for obstructions in the plumbing or dirty filters that could restrict water flow through the heater. Reduced flow can cause the heater to trip safety sensors or fail prematurely.
- Visual Inspection: With power disconnected, visually inspect the heater and its connections for any signs of leaks, corrosion, or damaged wiring.
- Winterization: If winterizing your spa, ensure the heater is completely drained to prevent freezing damage.
7. Troubleshooting
Before attempting any troubleshooting, ensure power is disconnected. If you are unsure about any step, contact a qualified technician.
