Lamp Replacement Procedure
- Disconnect power to the UV system and close water supply valves before beginning any service work
- Remove the quartz sleeve carefully, then extract the old S740RL-HO lamp from the ballast connector without touching the new lamp glass with bare hands
- Insert the new Viqua S740RL-HO lamp into the ballast connector, reinstall the quartz sleeve, and restore power to verify indicator light operation
- Mark your calendar for replacement in 12 months regardless of whether the lamp still appears to glow, as UV-C output degrades over time
System Fitment
The S740RL-HO lamp is designed exclusively for Viqua SP740-HO, Sterilight SC-740, and Sterilight SCM-740 UV disinfection systems. This lamp uses a proprietary design validated for dosage delivery in these specific chambers. Non-genuine replacement lamps sold at discount prices do not meet Viqua engineering specifications and will void your system warranty while potentially compromising disinfection performance. Isopure Water stocks only factory-original Viqua and Sterilight replacement lamps to ensure your UV system continues to provide validated microbial reduction.
