LA-1400S CEILING MOUNT AIR CLEANER
INSTALLATION INSTRUCTIONS
IT IS IMPORTANT TO READ THE FOLLOWING INSTRUCTIONS CAREFULLY – DAMAGE
TO THE PRODUCT OR TO INSTALLER AND PROPERTY COULD RESULT IF
IMPORTANT
1. Do not connect the power source until after the unit is mounted. Shock and/or damage could
result.
2. Be sure to shut the unit off prior to any service work.
3. Wear gloves to protect hands during installation as well as to keep surface of air cleaner free from
dirt and smudges.
4. All electrical wiring must comply with applicable codes and local ordinances. DO NOT connect
power supply until air cleaner has been installed and/or checked.
HOW TO DETERMINE THE NUMBER OF ELECTRONIC AIR CLEANERS REQUIRED
1. Calculate the volume of the room. Volume (cubic feet) = Length x Width x Height
2. Determine the circulation of the air needed, based upon 8 air changes per hour for average
conditions, to reduce the smoke and pollution. Use 16 air changes per hour for high
concentrations of smoke and contaminants, or when one has a desire to reduce smoke and
pollution even further.
3. The LA-1400S produces 800 cfm at low speed and 1100 cfm at high speed. To establish the
correct number of units to use, you should calculate the cubic feet of air in the area to be
cleaned, and then use a figure of 8 air changes/hour in that area for average cleaning, and 16 air
changes per hour for very polluted or smoke filled conditions. You should remember that the
slower the air passes over the surface of the air cleaner, the more efficiently the unit will
operate. Therefore, when calculating the number of units needed, take into account air flow and
cleaning capacity.
EXAMPLE #1
ROOM DIMENSIONS:
TYPE OF AREA:
AIR CHANGES DESIRED:
STEP 1 – Volume
50' x 100' x 10' = 50,000 CU FT
STEP 2 – Volume to be cleaned
50,000 CU FT x 16 air changes per hour = 800,000 CU FT per Hour
STEP 3 – Volume/Minute to be cleaned
800,000 CU FT per Hour / 60 Minutes per Hour = 13,333 CU FT Min (CFM)
STEP 4 – Number of units needed
13,333 CFM / 1,1000 (CFM of unit) = 12.09 or 12 units
