MAINTENANCE
Before performing any maintenance tasks on this unit, flip the On/Off switch into
the
Off
position and remove the supply cord from the unit.
1. Filter Maintenance
is most important to maintain a clean working environment. As dust, odors, and
microbes are collected from the air in the room, the filters start to fill. When filters are full, they restrict
air flow diminishing the efficiency of the
Fume Hood
. Filters must be replaced regularly to assure the
proper function of this unit.
a.
The
Pre-filter
(first filter) is identified by its white media and is located on the very bottom of the
stack. This filter captures the majority of larger sized contaminates in the room and will need to be
changed more often than the other filters in the unit. Replace the Pre-filter when the air flow drops
significantly, the filter appears substantially dirty, or every 3-6 months, which ever comes first.
Replacing the Pre-filter:
You will notice a group of three filters; the Pre-filter is the one on the bottom. In order to change
the Pre-filter you must remove the two above it. Start removing filters from the top and work down
through the group of filters. When installing the new Pre-filter make sure the metal reinforcement
side is facing up. Inspect the other filters and replace them in the opposite order then they were
removed.

b.
The
Secondary Filter
is identified by its white media and is the second filter from the bottom in
the stack.This filter captures the smaller particles that may slip through the Pre-filter. As a rule, this
filter should be replaced once every three replacements of the Pre-filter.
Replacing the Second Filter:
Comparable to replacing the Pre-filter, you will need to remove the filter above first, then remove
the Secondary filter. When installing the new Secondary filter, make sure the metal reinforcement
side is facing up.

For your convenience Vaniman offers a filter package which includes three Pre-filters and one
Secondary Filter. This filter package will enable you to replace your Pre-filters while reminding you
of the three to one filter maintenance schedule.

c.
The
Charcoal Odor Filter
(third filter) can be identified by its metal frame. The Charcoal Odor
Filter is located on top of the group of filters inside the unit. This filter absorbs odors in the air as it
is similiar to a chemical sponge used to collect odorous chemicals. The Charcoal Odor Filter must
be changed when an increase of odors from the unit is detected.
Repalcing the Charcoal Odor Filter:
Pull out the old Charcoal Odor filter from the unit. Remove the plastic packaging from the new filter
before sliding into place. Either side of the filter may face up. Vaniman recommends to always have
a spare, however, keep new unused filters wrapped in their plastic wrappers to ensure freshness
until use.
