MAINTENANCE
Washing the Electronic Cells and Prefilter
In order for your LAF
M
to maintain peak operating efficiency, the prefilter screen and the electronic cells must be washed
regularly. The frequency of this cleaning will depend on the atmosphere in which the units are operating. The best way to
clean the cells is by soaking them in hot water with LA-99 cell cleaning detergent (other methods can be used if time is a
restraint).
1.
Following the cell cleaner manufacture’s instructions, add LA-99 cell cleaning solution or
other detergent to hot water in an
appropriate container such as a stationary tub.
2.
Immerse the cell in the water and soak for 5 to 10 minutes. Then remove the cell and rinse
with clean water, making sure to
remove all residue from the cell surface.
3.
Check cells for broken ion wires or bent plates and repair or replace if necessary.
4.
Make sure the cell is completely dry before placing it back into the air cleaner.
5.
Remove lint and other dirt from the prefilter by vacuuming or washing it in a mild detergent
solution.
CAUTION: Care should be taken when handling the LAF
M
cells and filters.
1.
Edges may be sharp on the collection plates as well as the area near the ionizing wires.
2.
Be sure to wear appropriate gloves and goggles when dealing with a cell chemical of any
kind.
Contact with
the
skin is not recommended.
3.
Electronic air cleaners and their components are susceptible to damage. Take care when
working with them to avoid
equipment damage.
Replacing the HEPA Media Pad
The HEPA Media pad cannot be cleaned and MUST BE REPLACED every 9-12 months. Failure to replace a heavily loaded
filter can cause undue stress on the blower motors due to the reduced airflow and will void warranty.
Service
Should your LAF
M
malfunction, there are several simple checks which you can use to check the performance before a service
person need be called.
1.
Check to see if the fuse on the unit is tripped which would indicate electrical interruption to
the unit. Correct by replacing
fuse. If the circuit breaker or service box fuse is blown, that too
will need replacement.
2.
Be sure the electronic cell is in place and that the access door is locked down. Failure to have
this done will cause the safety
interlock to override the circuit.
3.
If the operating light is not lit after checking these things, a service person should be
consulted.
All electronic air cleaners undergo a process known as “arcing” from time to time. It is a snapping noise that comes from the
electronic cell when very large particles enter into the col-lection cell or when the cells are wet or extremely dirty. If an unusual
amount of arcing persists, check the collecting cells for broken wires, bent plates, or to see if they are very dirty. If arcing still
occurs, check with your service person or dealer.
