DiamaPro Systems AS-1000, Owner'S Manual

4. PRIOR TO USE

A. 

Remove any excess dust/dirt from exterior housing and control panel.

B. 

Be sure the HEPA Filter and Pre-Filters are installed properly with a 

positive seal.

C. 

Insure the unit is connected to a dedicated 10Amp, 

110/115 volt circuit.

D. 

Make sure unit is safely positioned as not to impede any entrances or 

exits of the work area.

E. 

If applicable, check exhaust port connections for tight seal.

CAUTION:

Insure your power cord is securely attached to the male 

recessed plug. If any movement or play is detected, change power 

cord immediately! If connection remains loose, immediately

replace the male recessed plug.

OPERATION

A. 

When utilized in containment, the AS-1000 should be positioned a 

minimum distance away from the entrance and located towards the 

center of the containment.

B. 

When using a HEPA filter, insure the filter is correctly installed and 

sealed. Anchor and secure the filter utilizing the supplied retaining 

brackets.

C. 

Install the Ring Filter and Pre-Filter pad into unit.

D. 

Insert the female end of your 10 amp rated, UL listed cord, into the 

male recessed plug on control panel.

E. 

To begin operation, depress the power switch to either the low or high 

position. Locate the differential pressure gauge located on the control 

panel. The gauge will register between 1.0” – 1.2” of water column. This 

is the initial reading when filters are new and unused. This reading will 

incrementally increase as filters become loaded with dust and debris. 

When the gauge reaches 1.6” – 1.8” of water column; either one or all 

of the filters are loaded and in need of replacement.

F. 

Pressing the power switch to the left will operate the unit in “Low” mode 

equivalent to 500 CFM.

G. 

Pressing the power switch to the right will operate the unit in “High” 

mode equivalent to 1000 CFM.

5. REPLACEMENT OF FILTERS

The work atmosphere will impact the frequency of filter replacements. As 

filters begin to load, the reading of the pressure gauge will increase

incrementally. When the Pressure gauge reads 1.6” - 1.8” or when airflow

is greatly reduced, check the condition of filters.

CAUTION:

If applicable, wear personal protective equipment during 

filter replacement. Please observe all Federal, State, and Local 

regulations regarding the handling and disposal of 

hazardous materials.
