INSTALLATION INSTRUCTIONS
SECOND STAGE
Position the unit on 50mm x 25mm wooden
battens (not supplied) laid across the joists
or raised platform if the insulation is thicker
than the joists so that the ducting between
the unit and the diffuser is not impeded.
Lightly screw the drilled battens to the
joist through the foam mounts and metal
washer provided. Fit the ducting to the unit
spigot using half of the tape provided.
Fig.1 Fixing Instructions
FIRST STAGE
Determine the position of the re diffuser. It must be located a minimum of one metre from
a smoke alarm but may be tted closer than one metre from a wall or other obstructions if
required. Position a dustsheet beneath the site you have chosen for cutting the hole for the
diffuser. Protect your lungs with a mask. Enter the loft space with the unit and check there are
no obstructions to your chosen position for the diffuser.
Cut an appropriately sized hole using the diffuser spigot as a template.

and check that the lters are securely in
place. For maximum airflow set the diffuser
fully open.
THIRD STAGE
Push ducting through the hole in the ceiling. Return to the hallway and connect the ducting onto
the neck of the diffuser. Secure the duct to the spigot of the diffuser using the other half the tape
supplied. Fix the diffuser in position using plasterboard plugs and the screws provided.

About your PIV L3
DO YOU KNOW WHAT’S GOING ON IN YOUR OWN HOME?
In a dwelling of 4 people, each will contribute
approximately 4 pints of moisture per day
– through showers, boiling kettles, cooking
etc totalling over 100 pints of liquid per
week.
Other airborne contaminants which exist
in a typical dwelling like dust, tobacco
products, exhaust gases – even chemical
emissions from furnishing and building
products further deteriorate air quality.
In older, less energy efcient dwellings,
there is a natural escape for this hot, damp
problem air – through ill-tting windows
and doors, uncarpeted floorboards, lofts
without insulation and so forth.
Improved building features such as cavity
wall insulation, double-glazing and draft
proong prohibit ‘natural ventilation’. Stale,
humid air is trapped – increasing the
condensation problem in the dwelling.
THE CAUSE OF CONDENSATION, DAMP AND MOULD
The Benets
Say goodbye to condensation & mould
Whole house ventilation
Improved air quality
Musty odours removed
Streaming windows stopped
Condensation control
Enhanced heat distribution
Benets allergy and asthma sufferers
MOISTURE
The typical household creates
around 100 pints per week - from
showers, baths, cooking etc.
CHEMICAL EMISSIONS
From everyday household
furnishings, building products etc.
FUMES
From tobacco products, exhaust
gases etc.
DUST
From furniture, carpets, bedding etc.
= Poor Air Quality = Condensation, Damp & Mould

How does my PIV L3 work?
The unit works by supplying fresh, ltered air throughout the home to transform a stagnant
and stale atmosphere into a fresh, healthy and condensation-free environment.
The unit delivers air into a home via a single input, usually located in a central landing.
How does my PIV L3 help?
It prevents the build-up of moisture in the house, controlling steam/condensation from
bathing and cooking to prevent the formation of black mould on walls, behind cupboards etc.
It will also help to stop dampness and musty smells caused by poor ventilation.

Energy Saving Benets
The unit will help you to save energy in the following ways:
Minimal Energy Consumption
Using the latest technology, the unit is powered by ultra-low watt motors to achieve low
running costs.
Solar Gain
The unit takes maximum advantage of the benets from solar gain within the loft space.
This is the natural accumulation of heat from the sun on bright days. Temperatures in the
loft are on average 3°C higher than outside, which results in a relative saving of around
150 Watts per day in an average modern family home. This equates to approximately
10% of annual heating costs.
Heat Distribution
Warm air accumulates at ceiling level. This air can be up to 7°C higher than the internal
air at ground level. By introducing an air supply from the loft space, the unit helps to
redistribute heat around the home to further reduce heating costs.
No need to open windows
To reduce humidity and condensation, people often have to open windows. This can
lead to a signicant energy loss, particularly in the winter period. The unit provides fresh,
ltered air to the home and reduces humidity without the need to open windows, saving
energy and heat loss.
Health Benets:
Reduces mould spores, a trigger for respiratory problems and allergies.
Reduces house dust mite populations by lowering humidity levels - a main trigger for
asthma and allergies.
How do I control my PIV L3?
The unit will operate continuously, 24 hours a day. It is important that the unit is not turned off.
The flow rate of the unit will be set at the appropriate level for your home during installation.
With the remote control switch you can change the unit flow rate/speed at any time at the
push of a button. You can also use it to enable or disable the comfort heater (see pages 5-6
for operation instructions).

About your PIV L3

What features does my PIV L3 have?
The intelligent comfort heater is designed to temper the air during periods of low external
temperature. It is capable of holding incoming air temperature accurately at 10°C. With the
function enabled, the comfort heater may be on 10% of the time, depending on the fan speed
setting and only activates at loft temperature of 10°C or below.
The unit has an automatic increased airflow setting. This function increases airflow rates
per setting by 10% to deliver additional air into the property at temperature above 19°C. At
temperatures above 25°C the unit will go into standby mode to prevent hot air being delivered
into the dwelling.
Maintenance
The unit has been subjected to rigorous testing and are constructed from durable materials.
There should be no requirement for any maintenance within the ve year period.
At the ve year service, the lter located on the unit must be replaced to ensure maximum
efciency of the unit. The lter is mounted around the unit with velcro, simply pull off and
replace.
How much does my PIV L3 cost to run?
The unit is very energy efcient. On a constant medium setting with the comfort heater
enabled, the heater will be ON around 10% of the time. With the comfort heater disabled the
unit will cost less than £6* a year.
*Based on an average electricity unit price of 15p.
Costs will vary depending on atmospheric conditions and unit settings.
Helpful hints and tips
Keeping your home condensation free:
• Try to keep the house as warm as possible for as long as possible
• Do not dry clothes over radiators
• Vent your tumble dryer outside
• Do not use parafn / Calor gas type heating
Energy bills:
• To minimise energy bills you may need to adjust the central heating down if the diffuser is
in the same room as your thermostat.
