Maintenance - Dri-Eaz LGR i- Serie Guide D'utilisation

At the end of the job
As with all dehumidifiers, once the drying job is
completed, it is important to make sure the unit is
completely purged of water before moving it. To ensure
that all water has drained into the pump, follow
these steps:
1. Turn the unit off and allow the plugged in dehumidifier
to rest for 10 minutes.
2. Press the PURGE key and while the purge pump is
operating, tip the unit back approximately 45° and hold
the unit in place. The manual purge cycle lasts
approximately 10 seconds.
3. Return the unit to the upright position and press
PURGE one more time to empty the pump.
Remove the dehumidifier promptly from the job site
once these steps have been completed.
Before transporting, be sure to remove the external drain
hose, drain it carefully, and return it to the pocket
provided on the back of the unit.

MAINTENANCE

WARNING! ELECTRIC SHOCK HAZARD. Unplug the
dehumidifier before performing any maintenance.
Before each use
Inspect the electrical cord for damage. Look for
fraying, cuts, etc. Do not use the unit if you find any
damage. Call Dri-Eaz for the nearest Service Center at
800-932-3030.
Inspect and vacuum filter as needed. The i-Series
dehumidifiers are equipped with a 3M™ High Air-Flow
filter. The HAF filter may be vacuumed clean and reused
up to three times. Do not rinse or wash the HAF filter,
as it will reduce the effectiveness of the electrostatic
material.
Keep a clean filter in the unit at all times to protect
internal components from dust and other particulate
build-up. Vacuum or replace filter before each job.
Replace only with a new 3M HAF Filter (Dri-Eaz part no.
F421). For parts and service call your local distributor or
contact the Dri-Eaz Service Department at
800-932-3030 or 360-757-7776.
CAUTION: Dust can cause the unit to overheat and
shut down. Do not operate when excessive dust or
airborne particles are present, such as during
sanding or spray-painting. Inspect and clean air filter
elements and coils frequently.
IMPORTANT: Replace the HAF filter whenever 1)
it has been vacuumed clean 3 times or 2) it has
been used on a mold remediation job or
otherwise exposed to potentially dangerous
contaminants.
