Product Features
Timer Fans
Timer fans are designed to be connected to the lighting circuit so that they will operate when the light is switched on, and stay on for a pre-set time after the light has been switched off.
Timer and Humidistat Fans
Timer and Humidistat fans are designed to be connected to the lighting circuit and will operate when either the light is switched on or when the humidity level exceeds the pre-set level between 60 and 90%.
Once the light is switched off, or the humidity level drops below the pre-set level, the fan will stay on for the time period set by the timer control, between 2 -30 minutes.
Noise Level
All ventilations fans have a low noise level, under 35dB.
Thermal Fuse
All Vimark ventilation fans have a thermal fuse which prevents the motor overheating if the impeller becomes jams.
Installation Instructions
- Switch off the mains supply before commencing the installation.
- Drill a hole in the wall to suit the fan and ducting: 4” fan Ø 110mm hole max.
If mounting the fan on the ceiling, position the fan between the joists - Route ducting from the fan position to the external grille position, ensuring the end of the ducting is flush to the walls. Ducting runs should be as short as possible for optimum performance.
- Remove the front cover of the fan by undoing the securing screw on the bottom edge. To access the cover on the Flat Facia fans remove the front plate first by pulling away from the pillars in each corner.
- Hold the body of the fan in position and mark on the wall/ceiling the four fixing screw positions and the cable entry hole.
- Drill and plug the wall/ceiling.
- Route the cable so that it exits through the wall ceiling at the position marked, leaving enough cable protruding so it can be terminated.
- Fix the fan body in position.
- Terminate the cable. (For Zone 1 fan the internal cover must be removed to access the terminal block)
- Fit the front cover and tighten the securing screw.
- Switch on and check for correct operation.
Ventilation Fan Performance
Vimark ventilation fans are design to meet the requirements of The Building Regulations – Approved Document F1 Means of Ventilation, and The Building Standards (Scotland) – Domestic Ventilation.
These Building Regulations and the Domestic Building Services Compliance Guide state the intermittent extract ventilation fans should have a specific fan power (SPF) less than 0.5W/(ltr/sec). Vimark fans meet this requirement.
Fan Positioning
Vimark ventilation fans are designed to move air over short distances, typically under 2m, and are suitable for through wall installations. These ventilation fans can also be installed in ceilings with the ducting length under 2m.
The ventilation fan should always be sited in the wall or located on the ceiling furthest from the main source of air replacement, e.g. door, to ensure optimum performance. The fan should also be located as high as possible.
