AQUA-RITE PCB Repair Kit 23B

The SL32 2R023 can safely replace the SL32 2R025 or AS32 2R025 

All 3 thermistors have identical operational specifications except the AS32 version can absorb more dissipated energy before failing in an intense over voltage/current.B

Both will sacrificially fail when the excess voltage exceeds the operational specifications in case of  a major lightning strike.

This sacrificial failure acts as a high energy fuse, protecting the rest of the logic circuitry. (One blown component instead of destroying most elements in the logic circuitry.)

(This Kit contains 1 Thermistor, 2 Varistors,and 2 Fuses)

1 Ametherm SL32 2R023

High Energy Replacement ICL Thermistor

&

2   Littelfuse V150LA2P Varistors

(Most PC Boards use 2 Varistors.)

&

2  Mini-Blade 20A 32V Fuses

(One Fuse used on PCB)

HAYWARD / GOLDLINE / AQUA-RITE GLX-PCB-RITE

This board failure is often due to the "sacrificial" destruction of the fuse, or the thermistor and/or varistors used to protect the circuit from high voltage and high current surges that could occur after a lighting strike during thunderstorms or other power surge.

Normally the thermistor protects the circuit on start-up, providing a relatively high resistance (2 Ohm) at ambient temperature to limit "InRush Current", and then essentially disappearing from the circuit (0.02 ohm) when the current is near or equal the design current of 23 Amp. (The Aqua-Rite circuit is fused at 20 Amp)The part will fail when a power surge is much greater than the power handling capability of the part. 

(It is possible the fuse may blow before the Thermistor or Varistors fail.)

A valid replacement thermistor is:

Ametherm ICL - SL32 2R023

Inrush Current Limiting (ICL) Thermistor

(1 Thermistor included)

KIT 23B ALSO INCLUDES:

2 VARISTORS (V150LA2P)

Varistors are used to "CLAMP" the incoming Voltage as a second protection device.

The Aqua-Rite Unit uses 2 LittleFuse V150LA2P Varistors 

(Use to repair: Hayward Aqua Rite PCB (GLX-PCB-RITE) Pool Chlorinator)
