Cleaningthelters
Although the Dry-Matic is designed to run continuously for
years, the lters do need cleaning every 8 months or so for
optimal performance (clean at least yearly).
When the hall controller display starts ashing - this indicates
it is time to clean the lters.
The white lter bag can be machine washed on gentle cycle
or hand washed - vacuum rst to remove excess dust.
Alternatively replace with a new one.
The carbon lter inside the lter box should be checked - if it
is showing signs of dust and dirt, it can be vacuumed clean
or replaced. It is recommended to clean or replace every
second year.
You may prefer to get a professional to climb into the attic
space to access the lters.
Dry-Matic Maintenance
Optional Heater
The DM07B units have been tted with a thermostatically controlled duct heater
that tempers the incoming air when it is cold in the attic.
Your Dry-Matic is essentially fully automatic in operation once commissioned to
suit your home.
•
Anti Condensation Mode - when the attic temperature is cooler than the house
temperature, the Fan operates at trickle speed to provide background ventilation
24/7.
•
Auto Summer Shutdown - when house is hot and attic is very hot >27°C, the
system shuts down until the attic temp decreases again.
•
Heater Mode (heated models only) - if the attic is cold, <15°C, the heater can operate to
temper the incoming fresh air.
