please call 215-887-2196 or email
Preventive Maintenance
The humidification system utilizes a pair of ultrasonic transducers that has an estimated
lifespan of at least 3000 hours of run time after which it may need to be replaced. The
ultrasonic transducer is not user replaceable. Please contact ETS for assistance with
repair/replacement. To maximize the life of the transducer, use an appropriate water
supply (deionized water or distilled water) and perform regular preventive maintenance
after
every
500 hours
of operational use.
Any time the humidifier is not being used for more than a week, drain the water
completely out of the basin.
Accessory filters have limited lifespan. It is recommended to replace the filter regularly to
avoid degradation in humidification capability or contamination (e.g. mold). In closed-
loop, high-humidity conditions, filters may become oversaturated with moisture and resist
the flow of air. It is recommended to replace over-saturated filters. Filter lifespan is highly
variable based on each specific application, however, to maximize the humidification
capability of the Model 5482 it is recommended to replace the in-line filter
monthly
.
Preventive Maintenance
Step 1
– Power OFF and Drain the Basin
Unplug the humidifier AC line cord from the
“HUMIDITY” AC outlet of the controller.
Place the unit above a small container at the
end of the drain valve to collect drained
water.
Turn the drain valve to ON position with the
tap lever turned parallel to the shutoff valve
inlet and outlet and wait until draining is
complete.
