SP103 Pool Pump

Theralaux Theraflo 1hp

Good

Health notesPump is running fine. Oring on the front union had slipped out causing pump to lose prime. Re-seated oring and it primes without any issues

View manual

SP103 Therachlor Chlorinator

Theralaux Therachlor 25g Chlorinator

Needs attention

Health notesChlorinator seems to work fine and produce chlorine, but the main display buttons are faulty at times. This doesn't need replacing at the moment, but early signs of the main unit being unusable. Fine for now but keep an eye on it.

Recommended settingsCheck salt level as Low TDS warning was coming up.

SP103 Media Filter

Theralaux Theraflo 255 Glass Filter

Good

Health notesFilter seems to be working fine. Pressure gauge needs replacing though. This will give a better indication of wether it needs backwashing or not.

Recommended settingsReplace pressure gauge on top of filter. Backwash the filter whenever the pressure gets to 130-150kpa

SP103 Heat Pump

Theralaux Theratherm 9kw Heat Pump

Needs attention

Health notesUnable to get heater running. The red "ON" symbol on the display means "No water flow" although there was definitely water running through the heater. I don't think the heater needs replacing, it may just need a new flow switch.

Recommended settings26c-28c is the ideal temp when working. Potentially replace the flow switch

Dosage guidance: Estimates use Hy-Clor published product-chart rates for Calcium Increaser (200 g/10,000 L per ~15 ppm) and Stabiliser (500 g/10,000 L per ~50 ppm). Salt uses Passport chlorinator settings; buy whole 20 kg bags but add only the calculated amount. Copper advice depends on the exact controller. Always use calcium hardness (not total hardness) for calcium calculations. Check the exact product label, maximum single dose and application directions; never mix chemicals. Dose each chemical separately in the order shown, allowing the circulation time on its label. Never mix chemicals. For ordinary independent corrections, a single final retest is sufficient; if a step specifically requires an intermediate test, do that before continuing. Do not swim when sanitiser readings are unsafe. Estimates are not water-safety clearance or Hy-Clor approval.

Trouble Shoot

Technician: Matt Hoffman

25 September 2026

Works completedCame to inspect pump not priming and timers not working. O Ring on the front of the pump had slipped out which caused the pump to lose prime, and activate "Low Flow" warning, so timers wouldn't work. Re-seated o ring, pump now primes fine and timers are working.

Recommendations & Next StepsOur advice for your pool

Replace the pressure gauge on the filter. Investigate whether replacement flow switch will fix the heater. Check water chemistry, mainly salt level.
