3. Operation
3.1 Transporting the Quest H5
The H5 should be transported vertically or horizontally on the appropriate feet located on the bottom of the unit or
opposite the handle.
3.2 Electrical Requirements
The Quest H5 HEPA System can be plugged into a grounded 15 Amp circuit. It draws about 2.4 Amps with clean filters
and no ducting. The amp draw will decrease slightly with added ducting and as the filters load with particulate.Due to the
presence of GFCI receptacle, the unit must be plugged directly into a wall outlet. No extension cords should be used.

3.3 Air Ducting
3.3A Inlet Ducting
Occasionally the area to be filtered is dicult to access and/or the unit cannot be located in the area. In such cases, the
air can be ducted to the unit’s inlet.
A round 16” diameter flexible duct can be attached to the unit inlet. It connects by placing the wire in the duct over the
duct collar lip at one location and working over it over the lip gradually. It may be removed after use for easier transport
and storage. Flexible 16” duct is available from Therma-Stor LLC. (4028357)
3.3B Oulet Ducting
A detachable trapazoid shaped exhaust ring is supplied that will allow 10” round lay-flat plastic duct to be attached to the
Quest H5 HEPA System outlet. Lay-flat plastic ducting is available from Therma-Stor LLC. (4024935)
To attach ducting to the collar, remove the ring from the unit by pressing release tab at the top of the grill. Put the plastic
duct end through the inside of the ring. Roll the duct end outward so that it over-laps the outside of the ring. Clip the
ring back onto the exhaust grill.
3.3C Negative Air Ducting
The Quest H5 HEPA System can be used to filter and exhaust air from a space. When exhausting to outside the space,
the space will be under a slight negative pressure. This will help prevent airborne particles from leaving the space, because
the negative pressure will draw air in through openings in the space’s exterior surfaces.
CAUTION: Exhausting too much air from a space with open combustion devices (e.g. furnace, fireplace or water
heater) can cause those devices to backdraft. This can contaminate the space with potentially fatal gases.
In such cases, the Quest H5 HEPA System must be used in one of the following three ways:
A. As a filtering unit only. Exhausting no air from the space and thus causing no negative pressure or backdrafting.
B. Exhausting a very limited amount of air which does not cause backdrafting. In case B, the open combustion devices
must be thoroughly checked to guarantee that they do not backdraft while the Quest H5 HEPA System is running.
C. Direct the outlet duct from the H5 HEPA System to the room with the open combustion device(s). This will
positively pressurize the room with HEPA filtered air, thus preventing backdrafting. As in case B, those combustion
devices must be checked after the H5 HEPA System is running to guarantee that they are not backdrafting.
3.4 Power/Speed Control
The power/speed switch is located on the control panel. When turned on to any speed, it powers the impeller fan.
Occasionally the impeller fan may not start on low speed. If this occurs, rotate the speed control to high speed until the
impeller fan starts, then adjust it to a lower speed.
CAUTION: Do not remove HEPA filter with the unit on. Removing the top and filters while running will expose the
dangerous rotating impeller fan. Disconnect the appliance before changing filters.
3.5 Resettable Circuit Breaker
The 12 AMP thermal response resettable circuit breaker protects the unit and devices connected to its duplex GFCI
outlet.
The circuit breaker is designed to sense the total current draw through the circuit. The circuit breaker “trips” when more
than 12 amps of electrical current are drawn through the device’s power cord. Should an over-current condition occur,
the H5 on-board circuit breaker prevents nuisance visits to a remote power junction box.

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 o 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% ecient (per ASHRAE 52.1-1992), MERV-7, pleated fabric pre-filter.
B. 99.97% DOP ecient 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.

Airflow on high speed with all filters clean and no ducting is slightly over 500 CFM. The unit can be run with very dirty
filters and virtually no flow without harming the unit. The operator’s decision to change filters should be based on filter
cost vs. the unit’s filtering eectiveness. If airflow is 250 CFM vs. 500 CFM, the unit will filter particles from a space at
half the rate. The operator must judge if that is acceptable.
If the operator determines the filters should be changed due to low airflow, it is most economical to change them in the
following order:
Change the pre-filter (top) first. This is the least expensive filter. Recheck the airflow. If the airflow is acceptable, no
other filters need to be changed.
If the airflow is still too low, the HEPA filter must be changed. To remove the HEPA filter, follow these steps:
1. Loosen the eight screws one revolution
2. Rotate all eight clips out of the way.
3. Remove old filter.
4. Installing the new filter is the reverse of these instructions
4.2B Optional Activated Carbon/Potassium Permanganate Filters
Optional gas phase filters are available from Therma-Stor. They use a blend of activated carbon and potassium
permanganate. This blend removes the vast majority of gaseous contaminants encountered in most filtering applications.
The activated carbon removes the heavier volatile organics while the potassium permanganate removes lower molecular
weight contaminants. This is well suited to the smoke odors present after fire damage.
The life of the media blend depends upon both the hours used and the contamination level. Another advantage of the
blended media versus activated carbon only is that part of the blend changes color as it loads up with contaminants. It
starts out black, then turns pink, then brown, and finally white. It is best changed when it passes the brown stage and
begins to turn white. It has lost most of its eectiveness at that point.
The filter is the same size as the pleated fabric filter. Install it in place of the pleated fabric filter.
5. Service
CAUTION: Servicing the Quest H5 HEPA System with its high voltage circuitry presents a health
hazard that could result in death, serious bodily injury, and/or property damage. Disconnect the
appliance from the power supply before servicing. Only qualified service people should service this
unit.
