IMPORTANT: Total amperage of the H5 plus all devices plugged into the receptacle must not exceed 12 amps. The
circuit breaker will not allow for loads in excess of 12 amps, although there is a time delay before the overloaded circuit
is broken.
IMPORTANT: When the Quest H5 is plugged into a standard “powered” wall outlet the Quest H5’s duplex outlet is
electrically “HOT” and AC voltage is present
3.6 GFCI Protection and the On-Board Duplex VAC Outlet
The standard AC voltage outlet GFCI (Ground Fault Circuit Interrupter) protection promotes operator safety in wet
applications. GFCI devices trip when a fault to electrical “ground” is sensed.
It is recommended to check the GFCI protection prior to operation. To check, push the “TEST” button located on the
GFCI duplex outlet. If operating properly the “RESET” button on the GFCI outlet will pop out. A tripped GFCI is
indicated by a small LED. The device can only be “RESET” when the H5 is connected to a wall outlet providing standard
voltage. This duplex AC outlet allows the inter-connection of other AC powered devices. The sum total amperage of all
devices plugged into the receptacle must not exceed 10 amps.
3.7 Servicing
Before each use inspect for damage, blocked inlet or outlet.
Inspect the GFCI to ensure it is not in a “tripped” condition. Push “RESET” to reset the GFCI.
When the Quest H5 is first turned on, check for excessive vibration. If the unit vibrates excessively or if impeller rubs on
housing, turn off the unit immediately. Have a service technician inspect the unit to locate the problem.
4. Maintenance
Use extreme caution when changing the HEPA filter as hazardous material could be trapped in the media. Always
make sure to dispose of filters in the appropriate way. If you are unsure of how to safely dispose of any filter-consult an
industrial hygienist to ensure that all hazardous materials are contained and disposed of properly.
4.1 Air Filters
The standard Quest H5 HEPA System is equipped with two filters that progressively filter out smaller particles.
An optional activated carbon/potassium permanganate filter can be also added. These filters must be checked
regularly. Operating the unit with dirty filters will reduce the airflow, but will do no harm to the unit. The unit
can be run indefinitely with dirty filters.
The two standard filters used are listed below (as installed in the unit from top to bottom):
A. 25 to 30% efficient (per ASHRAE 52.1-1992), MERV-7, pleated fabric pre-filter.
B. 99.97% DOP efficient HEPA filter.
4.2 Filter Replacement
4.2A Filter Change Light
When the green “filter change light” illuminates. It may be time to replace one or both filters.
To check airflow accurately, an airflow meter or anemometer must be used:
When the filter change light illuminates; remove all ducting and run on high speed. if the filter light remains lit; replace
the pre-filter and run on high again. If the light remains; it is time to replace the HEPA filter for full 500 CFM
performance.
