1 foot from the unit and again approach the nonadhesive side of the tape with your
free hand, If the tape has been neutralized, it will not attract.
CAUTION! ELECTRICAL SHOCK HAZARD – Do not insert objects through
intake or outlet grille.
Do not try to verify operation of the unit by drawing a spark from an ion emitter
point. The design of the balancing circuit makes the “spark test” inconclusive.
Sustained grounding of the ion emitters may damage the balancing circuit.
Ion Balance Check
To test the unit for ion balance, the use of a charged plate monitor such as the
SIMCO Electrostatic Analyzer H0601(SSD) or cpm374(Warmbier) is recommended.
Offset voltage should be measured and checked against the Ion Balance in Section 3,
Specifications.
Testing value can be changed with difference of temperature, humidity and ambient
environment.
Do not try to determine ion balance by holding a static meter in the ionized air
stream. This will result in s meaningless reading.
Ion balance adjustment
This Blower is designed with function of ion balance adjustment. If the offset
voltage (ion balance deflection) is too much, you can adjust the ion balance. Use the
screwdriver to adjust the balance localizers back of the unit respectively. When ion
balance lean to positive, adjust clockwise. Adjust clockwise to produce negative ion;
When ion balance leas to negative, adjust anticlockwise. Adjust anticlockwise to
produce positive ion.
NOTE: The two fans are adjusted at the same time when adjusting the ion balance.
Calibration
The BLOWER OVERHEAD’s ion output is inherently balanced by design. If, after
adjusting the ion balance, the offset voltage is still too much ,please contact our
Customer Service.
