Installation
Extractor Installation Procedure
Remove Fume Extractor from the shipping carton and inspect for any damages. Make sure
you have access to the unit for filter maintenance.
Connect the power cord into the outlet on the side of the system. Plug the power cord into a
grounded wall socket.
Connect the arms/hose to the inlet on the base of the fume extractor.
To power up system, depress the power switch, located on the bottom right of the unit. The
operator can expect a delay of a few seconds before hearing the motor running. This is due to
the built-in motor “Soft-start” feature.
If utilized, connect the supplied remote Start/Stop switch to the system and site the switch
in a convenient position on the workbench. We recommend that this switch be used for your
convenience.
Position the extraction arms to optimize fume capture.
Follow maintenance procedures on next page.
Caution
To provide protection against the risk of electrical shock, connect to properly grounded outlets
only.

residue. Be sure the unit is turned off while cleaning.
The cooling inlets and outlets should be cleaned once a year to prevent build up of dust and
overheating of which are on each side of the unit.

Model 35470
Filter replacement indication
As fumes are filtered inside the unit, any particulate will be captured and over time will start
to clog the filter. This clogging will result in a reduction of the airflow, which may reduce the
amount of fumes extracted from the work area. Once the filter starts to become blocked an
audible alarm will sound from the main unit. This is to signify that filter replacement is required.
35472, 35473 - HEPA/GAS Filters Only
As fumes are filtered inside the unit, any particulate will be captured and over time will start to
clog the filter. The coarse particles are collected in the pre-filter while fine particulate will be
collected in the HEPA filter. This clogging will result in a reduction of the airflow, which may
reduce the amount of fumes extracted from the work area. Once the filters starts to become
blocked an audible alarm will sound from the main unit. This is to signify that filter replacement.
When using a HEPA or Gas Filter initially replace the pre-filter (35471). If this does not silence
the alarm then replace the main filter too.
Pre-filters should be replaced approximately every 4 – 6 weeks depending on the application.
We recommend that a stock of replacement filters be kept for optimal extraction performance
and minimum down-time. MENDA part number 35471.
Warning!
Do not attempt to clean filters. Attempted cleaning can damage filters and cause
potential risk to health and equipment.
Note:
MENDA recommends replacement of Main Filters annually as a minimum. Use only
original replacement filters.
