EXAMPLE #2
ROOM DIMENSIONS: 50’ X 30’ 10’ CEILING
TYPE OF AREA: OPEN OFFICE AREA WITH MULTIPLE PERSONNEL
AIR CHANGES DESIRED: SOME SMOKERS & 20 DESKS –USE 8 CHANGES/HOUR
STEP 1 –Volume
50’ x 30’ x 10’ = 15,000 CU FT
STEP 2 –Volume to be cleaned
15,000 CU FT x 8 air changes per hour = 120,000 CU FT per Hour
STEP 3 –Volume/Minute to be cleaned
120,000 CU. FT per Hour / 60 Minutes per Hour = 2,000 CU FT Min (CFM)
STEP 4 –Number of units needed
2,000 CFM / 1,1000 (CFM of unit) = 1.8 or 2 units
PROPER LOCATION OF THE MODEL LA-1400S AIR CLEANER
Locate electronic air cleaners consistent with existing air circulation in the room so that the heating and
air conditioning systems are complemented by the air cleaners. Air cleaners must be mounted to strong
structural parts of the ceiling with adequate head clearance, and should be a minimum of 10 feet from air
intake or exit ductwork.
MOUNTING YOUR LA-1400S ELECTRONIC AIR CLEANER
The LA-1400S comes with a 6’ cord, but it is the responsibility of the purchaser to provide an adequate
outlet which meets local codes. An approved extension cord may be used if it meets local and national
codes.
The LA-1400S is designed with 4 mounting holes on the top and bottom of the unit. Eye bolts are
provided with the units so that they may be hung by chains from supporting beams on the ceiling. If you
choose the optional wall mount for the LA-1400S, see the instruction sheet included with the Model
10009 wall mount. The mount using the included eye bolts, follow the instructions below. The unit may
be hung so the air flow is from the left to the right, or from the right to the left depending on the needs of
the customer.
1. Choose an area which compliments the rest of the air flow in the room
before you mount the air cleaner.
2. Make sure you have correct lengths of chain, and that it is capable of
sustaining the weight of the unit. Standard hardware item, link chain with
working load of at least 100 lbs. Also make sure you have mounting lag
screws or equivalent fasteners to attach the chain to the ceiling beams or
studs. In some instances, it may be necessary to construct a mounting
frame to properly suspend the unit.
3. Locate the ceiling studs or beams and attach the correctly sized chain.
Chain length should be such that it will not allow the LA-1400S to have a
floor to bottom height which would pose a hazard to room occupants. A minimum height of eight
feet from floor to bottom of unit is recommended when chain hung.
4. After securing the chain to the ceiling studs or beams, us 4 “S” hooks on the chain to mount the
air cleaner cabinet to the chain. (It is a good idea to take out the electronic cell and other parts to
make the cabinet lighter when mounting and then to replace the internal parts into the unit.) The
