MAINTENANCE
WARNING! ELECTRIC SHOCK HAZARD. Unplug
the LGR1800 before performing any maintenance.
Never use a water hose or pressure washer to clean
coils, as water entering the electrical compartment
could cause a shock hazard.
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 service on +44 (0)1908-611-
211.
Inspect and vacuum filter as needed. Keep a clean
filter in the unit at all times to protect internal
components from dust and other particulate build-up.
The LGR1800 is 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.
Replace only with a new 3M HAF Filter (Dri-Eaz part
no. F372). For parts and service call Dri-Eaz Service
Department on +44 (0)1908-611-211.
CAUTION: Dust can cause the unit to overheat and
shut down. Do not operate when excessive dust or
airbourne 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 mould remediation job or
otherwise exposed to
potentially dangerous
contaminants.
Monthly

cause the unit to overheat.
Clean when visibly dirty. See
Fig. E.
1. Unplug unit
2. Remove housing, locate
coils and allow coils to dry if

that may cause damage by
bending them.
Check catch basin tray, and clean when dirt and
debris are present.
1. Wipe clean with a rag.
