Installation Procedure
Based on the above criteria:
1. Fit Diffuser
Before cutting hole for diffuser, check that it will clear ceiling
joists and roof structure. Use circle template to cut correct sized hole in the
ceiling. Attach duct to grille, taping the centre duct sleeve to the grille spigot
then separately taping the insulation/outer to the spigot. Feed ducting
through the hole and clip diffuser in place using the spring clips. Ensure
grille has a minimum gap of 16mm between inner disk and outer collar.
2. Assembly of Unit
It is suggested that this is done in a clear space on the
floor.
FAN: Mount fan brackets / hanging lugs to side of fan.
HEATER (on heated models): Fit to inlet of fan using 4 screws provided
(note airflow direction for fan is shown by an arrow on the terminal
cover). Ensure airflow direction arrow on heater is the same as
direction on fan, ensure heater is mounted so marked top is installed
upright.
FILTER BOX: Fit to heater (on heated models), or fit to the fan using the
supplied collar, so that the hanging bracket is on the heater/fan inlet
side. Ensure airflow direction arrow on filter is same as fan.
PRE FILTER: Fit white pre filter bag to inlet of filter box.
3. Pre Wiring
Using supplied flying leads, connect attic control unit to fan
and heater (on heated models). Check wiring diagrams on components
carefully. For 3 speed fans, wire to the high speed (black) wire as indicated
on the fan junction box.
4. Installing in Attic
Lift assembled unit into attic space. Fit supplied
cup hooks (x2) to roof structure. Clip supplied bungies (x3) to the three
mounting points on assembled unit. Lift unit into position and hook other
end of bungy cords over cup hooks. Attach duct to fan outlet, taping core
and insulation/outer as before. Adjust length of bungies so unit is level and
tighten cable ties to lock unit into position.
5. Mount & Set Attic Controller
Mount vertically, can be fixed to the timber
framing. For DM01B & DM07B models, set the top Summer Off” thermostat
to 27°C, and the lower “Hi/Lo”(for DM01B) or “Heater” (for DM07B)
thermostat to 15°C.
6. Power Supply
Connect a power supply to attic controller isolating switch
(by registered electrician).
7. Check Operation
