The LUF-series Lufran fluoropolymer inline water heater requires only a routine inspection every 6
months to check the operation of the various operation and safety devices. The maintenance procedures
listed here should only be performed by qualified technicians. Many of these devices require the control
system to remain operational during inspection, while others may be checked while the unit is completely
powered down.

Several maintenance tasks can be completed simultaneously while the cabinet access covers
are open and lockout/tagout procedures are in place.
