WARNING: Electrical shock hazard. Always disconnect power before installing or servicing this device.

• Installation should only be performed by a qualified electrician or service technician in accordance with all local and national electrical codes.
• Ensure the power supply to the equipment is completely disconnected and locked out before beginning any work.
• Verify that the pressure switch specifications (3A, SPST) are compatible with your system's requirements.
• Do not exceed the specified current rating of 3 Amps.
• Protect the switch from physical damage and extreme temperatures.

4. Tāuta me te Tatūnga

4.1 Nga Tirohanga i mua i te whakaurunga

• Ensure the system is depressurized and drained if necessary.
• Confirm the new pressure switch matches the specifications of the original part.
• Gather necessary tools: pipe sealant tape or compound, wrench, wire strippers, screwdriver.

4.2 Tāuta Hangaia

1. Apply a suitable pipe sealant (e.g., PTFE tape or pipe thread compound) to the 1/8" MPT threads of the pressure switch.
2. Carefully thread the pressure switch into the designated port on your hot tub heater or plumbing manifold.
3. Tighten securely with a wrench, but do not overtighten, as this can damage the switch or the plumbing.

4.3 Waea Hiko

The 30408 is an SPST (Single Pole, Single Throw) switch. It typically operates as Normally Open (NO), closing the circuit when sufficient pressure is detected.

1. Identify the Common (C) and Normally Open (NO) terminals on the switch (refer to Figure 3.2).
2. Connect the appropriate electrical wires from your control system to these terminals. Ensure connections are secure and free from corrosion.
3. Double-check all wiring against your equipment's specific wiring diagram.

4.4 Te Whakatikatika Whakatau

The pressure activation point can be adjusted using the black gear-like dial on the switch (refer to Figure 3.3). Turning the dial clockwise typically increases the pressure required to activate the switch, while turning it counter-clockwise decreases it. Consult your equipment's manual for the recommended pressure setting.

5. Mahi

Once installed and properly adjusted, the Balboa Water Group Pressure Switch 30408 operates automatically. When the system's pressure reaches or exceeds the set point, the switch will close its internal contacts, allowing electrical current to flow to the connected component (e.g., a heater or pump). If the pressure drops below the set point, the contacts will open, interrupting the circuit and deactivating the component. This mechanism serves as a safety device to prevent equipment from running dry or under insufficient flow conditions.

6. Tiaki

• Tirotiro auau: Periodically inspect the switch and its connections for any signs of corrosion, damage, or leaks.
• Te ma: Puritia kia ma te wāhi huri noa i te pana, kia kore hoki he paru.
• Taki Taumahi: If your system experiences issues related to water flow or heating, verify the pressure switch's operation by observing if it activates/deactivates correctly with changes in water pressure (e.g., by turning pumps on/off).
• Karekau he waahanga e taea ana e te Kaiwhakamahi: The internal components of the pressure switch are not user-serviceable. Do not attempt to disassemble the unit.

7. Te Raru

If your system is not functioning as expected, consider the following troubleshooting steps related to the pressure switch:

• Heater Not Activating:
  • Check for sufficient water flow. Low water levels, clogged filters, or air locks can prevent adequate pressure.
  • Verify the pressure switch adjustment. It might be set too high.
  • Inspect wiring for loose or corroded connections.
  • Test the switch continuity with a multimeter (with power disconnected). If it doesn't close with pressure, it may be faulty.
• Heater Always On/Off (Incorrectly):
  • The switch may be stuck in an open or closed position.
  • Check for debris inside the pressure port.
  • Ensure the pressure adjustment is correct.
• Nga turuturu:
  • Check the threaded connection for proper sealant application and tightness.
  • If the switch itself is leaking, it indicates internal damage and requires replacement.

If troubleshooting does not resolve the issue, contact a qualified service technician.
