Signs it's time to call now
Calibration failing at startup, energy dropping mid-day, cooling or flow alarms, or patients reporting weaker results at the same settings. These usually get more expensive the longer the system keeps running.

Common questions
How often should a Candela GentleMax be serviced?
Most clinics need a technician preventive maintenance visit every 6 to 12 months, depending on shot volume. High-volume hair removal practices should lean toward every 6 months.
How often should GentleMax coolant be changed?
Deionized coolant and the DI filter are usually replaced during each preventive maintenance visit, or sooner if the coolant looks cloudy or flow alarms appear.
Can staff replace the GentleMax flashlamp?
We don't recommend it. Lamp replacement involves high voltage and needs energy calibration afterward. A technician should do it.
