Keep external doors and windows closed during
colder weather to enable the DVS system to
gently ventilate your whole home.
The DVS system gently pressurises parts of your
home, pushing fresher, drier air into every room.
The damp, stale air is sucked out through the
exhaust side of the system.
During colder seasons when condensation is a
problem, we recommend keeping your external
doors and windows closed as much as possible,
otherwise the DVS system will be much less
effective. You may open doors and windows
on warm days if you wish to do so, without
noticeably affecting the DVS systems operation.
When using a clothes dryer, showering, bathing
or cooking, we suggest you open a window in
the relevant room and put the system on boost
for a period. Close the window again after you
have finished. Ideally, installing a vented extract
fan in these ‘high moisture’ rooms will assist
the DVS system to keep your home drier and
healthier.
Keep internal doors open, not just slightly ajar,
to allow air to flow into all the rooms, especially
bedrooms, for effective condensation control.
Closing internal doors prevents air from the
DVS system from ventilating those areas, often
resulting in continuing condensation problems
in those rooms. Doors should therefore be kept
open, or at least half open - not just slightly
ajar. This is especially true in bedrooms where
breathing from sleeping occupants can cause
condensation if doors are left closed.
Installing additional ceiling outlets in the
affected rooms is an easy way to ensure privacy
and solve condensation problems in rooms
where people prefer to close doors at night.

If necessary, slightly open drapes or blinds, or
create a gap between the drapes and window
frame at night to ensure adequate airflow can
reach window surfaces.
In some homes tight fitting roman blinds,
shutters, heavy floor-to-ceiling curtains or
window pelmets can sometimes make it difficult
for the drier air from the DVS system to reach
window surfaces.
When windows are ‘sealed off’ condensation
can sometimes occur, particularly during colder
weather. The DVS system is usually able to
clear any misting or minor condensation once
blinds and curtains are opened.
If you believe that your blinds or curtains are
causing a problem here are some tips:
• In living areas - open curtains at least a
metre wide when you go to bed at night,
• In bedrooms – pull curtains or blinds slightly
out from the wall if possible to create a small
gap so as to allow some air to reach the
windows.
Clean the ceiling outlets twice a year.
In the vast majority of cases, dust around the
ceiling diffuser is the result of dust already
inside the home being attracted by tiny
electrostatic charges that build up on the
surface of the ceiling or diffuser as the incoming
air brushes past these surfaces. Clean these
with a clean dry cloth or a dry brush.
Follow these simple steps to ensure your 5 year
warranty remains valid.
• Do not use your ventilation system without
filters
• Replace your filters every 12 months
• Ensure all parts are supplied by DVS
• Do not make alterations or modifications to
your unit
