•
Before going into the roof space to change your DVS filter ensure
that you have the required filter and a second filter if the optional
Summer ventilation or Integrated heat transfer is fitted. You also
need a clean dry cloth, and a good torch or safety lamp.
•
With a pair of strong scissors (recommended) or sharp utility knife,
carefully cut the plastic tie holding the used filter to the black
plastic ring of the DVS Air Handling Unit or loosen the pull cord,
which ever is applicable. Pull away the used filter.
•
Use the dry cloth to wipe any fine dust from the Air Handling Unit impellor and inside of the
inlet flange.
•
Pull the new filter over the inlet flange, tighten the new filter around the inlet flange using
the pull cord and toggle.
•
Repeat for each filter.
•
•
Please note that 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.

How to get the Best from Your DVS System.
Your DVS Home Ventilation System has been configured, installed and calibrated to best meet
your family’s needs and the size and layout of your home. However, in order to get the best
results it is important that you, the homeowner, follow these General Guidelines.

Maintain adequate home heating to balance
cooler airflows during colder seasons,
particularly in colder regions of New Zealand.
According to research by the Building
Research Association of New Zealand
(BRANZ), both adequate heating and
continuous ventilation are needed to prevent
excess moisture, condensation, mould and
mildew occurring in New Zealand homes.
If indoor temperatures are not maintained
at reasonable levels, even small amounts
of moisture inside the home can cause
condensation, even in homes which may
otherwise be well ventilated by the DVS
system. We advise a minimum of 16
o
C
in the occupied rooms for the purpose of
condensation control. All air contains water
vapour, but it can only hold a limited amount
without becoming saturated. The higher the
temperature the more it can contain.
Some customers may need to use additional
heating to balance the flow of cooler
drier air required to adequately control
their condensation and dampness. Most
customers have found that additional heating
in colder months is balanced by less heating
required during other times of the year, due
to solar heat gain from the roof space on
warmer days, and a drier home being easier
to heat and requiring less energy than a
damp home.
Don’t be afraid to adjust and customise your
settings to achieve a good balance between
condensation control and airflow, especially
in colder seasons.
Your DVS ventilation system has been
individually configured and calibrated to your
home. But we also recognise that every
home, location and family are different, so
we have designed the DVS system so you
can easily customise and adjust the settings
to best meet your needs, and changes in the
seasons, family circumstances and weather.
Don’t be afraid to ‘experiment’ with your DVS
system by increasing or decreasing the airflow
to achieve the best results. In general, the
greater the airflow the greater the level of
condensation control.
But remember, too much air may cool your home
unnecessarily in winter, while too little airflow
will not be effective in controlling condensation.
Experiment with your controller to find the right
balance for your home, and remember to use
additional heating if needed to ensure both a
dry and comfortable home.
You might wish to increase the airflow of
your DVS system if …
You have friends or family staying. More
showers, cooking and breathing may
cause condensation or misting due to
higher levels of moisture generated in
the home.
You may experience some temporary
‘misting’ or minor condensation during
very cold weather.
You might wish to decrease the airflow
of your DVS system if …
You are concerned about too much cooler
air entering your home during colder
seasons. Try reducing the airflow a little
at a time until you get to the point where
misting or condensation starts to appear.
The lower the airflow the lower the DVS
systems ability to control condensation,
so if you turn the system down too far,
condensation will occur more frequently.
