Before each use
Inspect the electrical cord for damage. Look for
fraying, cuts, etc. Replace the cord if you find any
damage.
Inspect, vacuum or replace filter. The 3M™ HAF
(High Airflow) filter may be vacuumed clean and
reused up to three times before replacement. Use a
HEPA vacuum and brush tool to remove any dust or
ABOUT 3M™ HAF FILTERS FROM
HAF filters from 3M provide superior particle retention, resist microbial growth on filter surfaces and allow for maximum
airflow throughout the filter loading cycle. Follow these guidelines to ensure maximum protection for equipment,
technicians and the job site:
Replace the HAF filter whenever it has been vacuumed clean and reused three times. HAF filters lose their effectiveness after
three uses.
Replace the HAF filter whenever it has been used on a mold remediation job or otherwise exposed to potentially dangerous
contaminants. Continued use of a contaminated filter risks the spread of contamination.
Do not wash or apply any liquids to the HAF filter. Exposure to liquids will reduce the effectiveness of the electrostatic material.
Do not operate without the HAF filter in place. Do not operate the unit with any other filter type. Incorrect filtration will reduce
unit efficiency and can cause damage to the unit.
Do not operate the unit when excessive dust or airborne particles are present. The high volumes of particulates present during
sanding, spray painting, or similar operations can clog the unit and cause damage.

debris. Do not use compressed air or expose the filter to
any liquids, as may damage the filter.
NOTICE: Replace used filters only with a new HAF filter
(Dri-Eaz part no. F368). Other filter types do not provide
adequate filtration or airflow. Be sure to install the new
filter in the correct orientation. See "Installing the HAF
Filter," p. 8. See also "About HAF Filters," below.
Monthly
Inspect coils and heat exchange block. Clean when
dust accumulation is visible. In normal use, dust can
accumulate and can restrict airflow, reducing
performance and causing the unit to overheat. See
"Cleaning Coils and Heat Exchange Block," p. 7.
To maintain appearance, wipe interior and exterior
surfaces with a damp cloth. For deep cleaning and a
lasting, protective shine, use Dri-Eaz MicroGuard
Cleaner and MicroGuard Protectant, available from Dri-
Eaz, or a similar automotive interior treatment.
As Needed
Clean Pump Check Valve and Basin. If the unit
displays the message "ER9 PUMP BLOCKED CHECK
PUMP & HOSE", the pump check valve and pump basin
may need to be cleaned. This requires removal of the
back cover. For instructions, see "Inspecting and
Cleaning the Pump," p. 11.
Clean coils and heat exchange block. Inspect the
horizontal evaporator (cold) coil with the back cover
removed. If excessive dust and debris is present,
vacuum thoroughly and/or clean with coil cleaner. See
"Cleaning Coils and Heat Exchange Block," p. 7.
CLEANING THE COILS AND THE HEAT
EXCHANGE BLOCK
To help keep the unit operating efficiently, keep the coils
and the air-to-air heat exchange block clean, and
periodically remove any accumulated dust and debris
from interior surfaces. See "Cleaning Coils and Heat
Exchange Block," p. 7.
