Raypak High Limit 1‑HL1‑Surface Mount Kit, 019045F, is a genuine Raypak high‑limit auto‑reset thermostat kit set to 140°F, used on Raypak Avia gas‑fired pool and spa heaters (models 264A and 404A) to prevent overheating.
What It Does
This kit provides the primary high‑limit safety thermostat (“HL1”) that monitors heater outlet/water temperature and opens the safety circuit if the temperature exceeds about 140°F, shutting the burner down. Once the temperature falls back below the limit, the auto‑reset thermostat closes again, allowing the heater to resume operation without manual reset.
