CSR Edmonds Maestro User manual

INSTALLATION INSTRUCTION
Maestro
Maestro is an extremely energy efficient and reliable roof ventilator used to extract hot, humid or moist air from the roof space,
allowing it to be replaced by cooler, fresh air. This helps prevent roof space temperatures from reaching extreme levels in
summer, thereby improving the efficiency of insulation, and resulting in a more comfortable home. The unit’s extraction rate
is equivalent to up to three wind-powered ventilators. The Maestro is available in 2
models, a 12V DC (low voltage) or Solar unit.
To achieve adequate ventilation it is imperative to provide adequate opportunity
for replacement air to enter the roof space, as shown in Fig 1.
It is recommended that at least 2 Whirly Mate ceiling grilles or at
least 8 under eave vents be installed evenly around the home for
each Maestro.
Selection of the number of Maestro’s and their location on the roof will depend on the characteristics of each problem and the
size of the roof area to be ventilated. However, one Maestro power vent can provide adequate ventilation for a 20 square (180m2)
home. Locate the Maestro(s) evenly around the roof to give the best results.
IMPORTANT NOTICE
• The Maestro is designed for general household ventilation only. DO NOT use to exhaust hazardous or explosive
materials and vapours.
• The Maestro has an unguarded fan assembly. DO NOT use in locations readily accessible to people or animals. The
fan is intended for use facing an unoccupied space only.
• The 12V DC model is designed for LOW VOLTAGE USE ONLY and must NEVER be connected direct to mains power.
Always use the 12V power pack supplied.
• Instructions for wiring the thermostat should be followed precisely.
• It is recommended that the Maestro be installed on roof slopes no greater than 45 degrees, as water ingress can
occur on steeper gradient roofs.
• DO NOT use this Maestro with any solid state speed control.
1. Select the appropriate position for the vent.
Remove a tile from the third row down from
the ridge cap. The removal of a tile higher
than this may damage the integrity of the
ridge tiles and is NOT recommended.
2. If the roof is ‘sarked’, cut sarking in a cross
and fold back corners to give a 300mm
square opening.
3. Take the flashing and push it under the
tiles above the opening created in the roof,
centre the vent over the opening. Dress the
flashing into the shape of the tile.
Note: Silicone can be used to ensure
installation is weatherproof.
4. Turn bottom edge of flashing down to seal
against lower tile.
5. From inside the roof, hook the fixing strap

METAL ROOF INSTALLATION

Note
1. Select the appropriate position for the
vent. Place the flashing with top edge
slipped under the ridge capping. Ensure
the flashing covers the corrugations or ribs
equally and is located between the roof
joists.
2. Mark the centre of each side to determine
where the centre of the vent will be. Mark
a 300mm circle using the centre mark. Cut
hole. Turn up corrugations or pans of the
roof sheeting around the opening.
3. Place Maestro on metal roof over the
opening and carefully dress sides and
bottom edge of flashing into the
corrugations. If the Profile proves to be
difficult an INFILL that matches the roofing
profile can be purchased & used on the
bottom edge of the flashing to achieve a weatherproof seal.
4. Run a small bead of silicone along the under side of the flashing & secure the flashing with self-tapping screws or rivets.
These are NOT included in the kit (approximately 8 are required).
Note: When a ventilator is required to be installed further down the roof & the top edge of the flashing is exposed, a flat
flashing with turned down sides should be installed over the top edge of the vent flashing & extended back to the highest
point under the ridge capping. Failure to install the ventilator using the back flashing may result in water ingress.
OPERATION
The Maestro motor has a rating of 1 amp with power consumption of 11W at 12V DC. The Maestro is supplied with a
12V 1.5 Amp power pack. The Maestro can be operated manually (via a two-way switch) or wired through the thermostat
(supplied with the 12V model).
