PRODUCT USAGE INSTRUCTIONS

OPERATION

Transporting the AS-500

The AS-500 should be transported vertically or horizontally on
the appropriate feet located on the bottom of the unit or opposite
the handle.

Electrical Requirements

The AS-500 can be plugged into a grounded 15 Amp circuit. Avoid
using extension cords. The presence of a GFCI receptacle requires
direct wall outlet connection.

Air Ducting

Always turn off the unit before attaching air ducting.

Inlet Ducting

Attach a round 16″ diameter flexible duct to the unit’s inlet
when necessary. Connect by placing the wire in the duct over the
collar lip and gradually working it over.

Outlet Ducting

A detachable trapezoid-shaped exhaust ring is supplied for
attaching a 10″ round lay-flat plastic duct to the AS-500 outlet.
Follow instructions to attach the ducting securely.

Negative Air Ducting

The AS-500 can filter and exhaust air from a space, creating a
slight negative pressure to prevent airborne particles from leaving
the space.

Resettable Circuit Breaker

The resettable circuit breaker protects the unit and connected
devices. Ensure total amperage does not exceed 12 amps to prevent
tripping.

FAQ

Q: Can I use an extension cord with the AS-500?

A: No, due to the presence of a GFCI receptacle, the AS-500
model must be plugged directly into a wall outlet. Avoid using
extension cords.

Q: How do I transport the AS-500?

A: The AS-500 should be transported vertically or horizontally
on the appropriate feet located on the bottom of the unit or
opposite the handle.

OPERATION
Transporting the AS-500
AS-500 should be transported vertically or horizontally on the appropriate feet located on the bottom of the unit or opposite the handle.
Electrical Requirements
The AS-500 can be plugged into a grounded 15 Amp circuit. It draws about 2 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 AS-500 model must be plugged directly into a wall outlet. No extension cords should be used.
Air Ducting
Always turn off unit prior to attaching air ducting.
A. Inlet Ducting
Occasionally the area to be filtered is difficult 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.
B. Outlet Ducting
A detachable trapezoid shaped exhaust ring is supplied that will allow 10″ round lay-flat plastic duct to be attached to the AS-500 outlet. 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.
C. Negative Air Ducting
The AS-500 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.

OPERATION
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, AS-500 on-board circuit breaker prevents nuisance visits to a remote power junction box.
! IMPORTANT
IMPORTANT: Total amperage of the AS-500 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
IMPORTANT: When the DiamaPro® AS-500 is plugged into a standard “powered” wall outlet the DiamaPro® AS-500’s duplex outlet is electrically “HOT” and AC voltage is present.
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 AS-500 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.
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 AS-500 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.

OPERATION
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 AS-500 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 AS-500 is running. C. Direct the outlet duct from AS-500 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 AS-500 is running to guarantee that they are not backdrafting.
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 or exhaust ring guard with the unit on. Removing the top and filters while running will expose the dangerous rotating impeller fan. Disconnect the appliance before changing filters.

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.
Air Filters
The standard AS-500 HEPA System is equipped with two filters that progressively filter out smaller particles. 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. Pre-filter. B. HEPA filter.
Filter replacement
A
When the amber “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. The operator must judge if that is acceptable. If the operator determines the filters should be changed due to low airflow, change them in the following order: Change the pre-filter (top) first. 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
