SECTION IV
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 Novair 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.
SECTION V
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.
PRE-FILTER REPLACEMENT
A. Set the power switch (diagram #20.1, item #3) to the off position. Disconnect power supply.
B. Remove Black Filter door (diagram #20.1, item #22) to expose the filters.
C. Reach in and remove the Pre-Filter (diagram #20.1, item #18). Dispose of Pre-Filter accordingly.
D. Replace the discarded Pre-Filter with a new Pre-Filter.
E. Reinsert the Black Filter door (diagram #20.1, item #22).
F. Insert the female end of your power cord into the Male recessed plug (diagram #20.1, item #1), and set
the power switch to the “High” position. If the reading on the pressure gauge exceeds 1.6” – 1.8”” of
water column, the Ring Filter #17 should be inspected.
RING FILTER REPLACEMENT
A. Follow steps A-D listed above referencing Pre-Filter replacement.
B. Reach in and remove the Ring Filter #17. Dispose of Ring Filter accordingly.
