NuAire MRXBOX95B-LH1 User manual

Today’s ho es are built with extra
insulation to keep war air in and reduce
energy costs. This however leaves very little
roo for your ho e to be naturally
ventilated.
Ventilation is about producing a good level of indoor air
quality and an environment that is free from condensation,
odours and indoor pollutants caused by cooking, washing
and day to day living. It is therefore important that you have
adequate ventilation in your home.
Having the Nuaire RXBOX95B-LH1 ventilation unit
installed in your home will not only ensure that your
property has a good level of indoor air quality, it will protect
the fabric of your home from condensation and remove
odours and indoor pollutants, resulting in a healthier living
environment for you as its occupant.

IThe Nuaire RXBOX95B-LH1 is designed to
extract the moisture generated in your home
from bathing and cooking whilst supplying
fresh filtered air into the property.
IThe stale air/moisture is extracted from your
kitchen and bathroom(s) and fresh air from
outside is supplied into your living areas and
bedrooms.
IThe system runs continuously so your home is
constantly ventilated and should not be turned
off for any reason with the exception of
maintenance purposes.
ITo ensure there is no wasted heat, the heat
exchanger within your unit will recover up to
95% of the heat it extracts from your home
and use it to temper the outside air brought in
to supply fresh air into your living areas.
IThe air that gets extracted and supplied into
your home is done so through a grille in your
ceiling. Please note that these should not be
touched as they have been positioned to
extract and supply the right amount of air out
and in to your home.
IThe filters that clean the incoming air are so
fine that they even exclude pollen.
IDuring the warmer months to provide you
with cooler air, the system is set to bypass the
heat exchanger. This means the air pulled in
from outside will not be tempered as it does
not use the heat that the heat exchanger has
recovered from your home.
IHOW WILL HAVING THE UNIT
IN Y HO E BENEFIT E?
IHaving the unit in your home will improve
your indoor air quality and create a healthier
living environment.
IResearch has shown that preventing moisture
in a home can reduce allergic reactions to dust
mites and other pollutants that affect those
suffering with respiratory disorders. The correct
use and maintenance of your ventilation
system will help to achieve this.
IThe unit prevents condensation by keeping
moisture levels low and when used correctly it
will protect your home from mould/damp.

IHOW DO I OPERATE THE UNIT?
At installation your unit will have been
set to run continuously to a level that
will adequately ventilate your ho e for
the ajority of the day.
There will be occasions however when the
humidity/moisture levels in your home will
increase from above normal, usually from
cooking, bathing or showering. During those
times, the unit has a functionality to increase its
capacity to remove the excess moisture. This
functionality is called boost.
We recommend that during times of cooking,
showering or bathing that you ensure your
system is set to boost.
There are a few ways that the RXBOX95B-LH1
system can be set to boost and which setting you
have in your home will have already been decided
by your housing provider or Housebuilder as part
of the installation.
The most common option used is a switch. The
switch is very similar to a light switch and will be
marked up so that you know it’s for boosting your
RXBOX95B-LH1 unit. The switches are typically
found by your counter top in the kitchen and
sometimes by a double pole light switch in your
bathroom(s).
To boost the system simply press the switch to
boost and when you are ready to turn it off, flick
the switch back to normal.
I portant please note that your boost
syste ay have been set to have a run
on ti er, which will result in the boost
function running between 5 to 30
inutes after the boost function has
been switched off. This is to ake sure
the excess oisture is totally cleared.
IHOW UCH DOES THE UNIT
COST TO OPERATE?
The MRXBOX95B-LH1 is energy efficient
and anufactured using the latest
generation of low voltage fans and
otors. This ensures very low running
costs.
