OPERATING GUIDELINES
General
This Home Ventilation System is capable of providing:
1. Constant low volume ventilation - required to improve air quality and control the effects of
condensation and/or
2. Free solar heating - complements other heating sources in cold weather.
Your Home Ventilation System is easy to operate and is basically set and forget. The aim is to
set the air flow rate to the lowest setting in order to manage the condensation/air problem for your
home.
Your unit has been calibrated to your house size which means the system should manage the air
flow to achieve the required result when set to the lowest setting most of the time. The air flow
rate can be increased by adjusting the fan speed control knob if condensation/air quality is not
being controlled adequately. It is recommended that the fan control knob setting should only be
increased in small steps and given sufficient time (1 or 2 days) at the new setting to check for the
desired result before changing it again.
Experience will determine the best setting. When you have found the correct setting for your
home,
leave it there
.
During summer, “Heat Recovery” should be switched off or the house will
become too hot.
The number of ceiling outlets required will depend on house size, layout and barriers to air flow
throughout the home. Normally one or two outlets is sufficient however if internal doors get
closed, extra outlets will be required.
The air from your Home Ventilation System is filtered for your protection. The filter should to be
replaced every 12 months. A replacement filter is available from your retailer and is easy to
change. The standard filter is a G4 grade which is adequate for dust control etc. A finer filter (F6)
is available for those people who suffer from air borne allergies and asthma. A carbon filter is
available which reduces the effects of wood smoke entering the roof space.
Ceiling vent outlets can simply be cleaned with mild detergent in warm water. Apart from
changing the air filter every year, there is no other maintenance required.
Typically a HVS system can achieve a significant and noticeable reduction in condensation within
the first few days, certainly within 1 month. The time required will depend on a number of factors.
To maximize the effectiveness of the HVS system please observe the following points:
Maintain adequate home heating as required.
Fine tune the air flow rate by finding the optimum minimum setting.
Keep all external doors and windows shut during cold winter weather (even during the
day).
Keep internal doors wide open to allow the fresh air to circulate throughout the home.
Slightly open curtains to allow air flow to the glass surfaces at night.
Slightly open wardrobes and drawers to allow air flow around clothing.
Avoid exhausting moisture into the roof space (eg kitchen, laundry and bathroom exhaust
fans should be ducted outside the home as per building regulations and not into the roof).
Change the filter every year.
