Mechanical installation

To install the module in an iCON fan follow the instructions below. for instructional drawings.

1. Remove the iCON fan front cover .
2. Lift the fan electrical terminal away from its mounting pillars and position on the module connector pins. Tighten the two screws with a suitable screwdriver. Ensure the leads are under the module retaining cable clamp.
3. Fit the module at a slight angle into the fan housing, ensuring that the locating slot is fully engaged in to the locating block on the fan.
4. Push the module against housing, ensuring the module clip holds it in place (clicks at the cable clamp). With iCON 15 & 30 the terminal will reposition back over mounting pillars.

Modules with pull cord: Ensure that the pull cord is properly located within the cord slot at the bottom of the fan.

Modules with PIR control: Remove the oval logo cap fitted at the bottom of the front cover of the fan. Replace it with translucent lens supplied with the PIR module. Note: The  lens must be replaced in order for the PIR module to functionproperly. Ensure the orientation of the lens is correct (i.e. the lens should be flush with the surface).

Connecting mains cable into the module
Connect the 12V Power Supply Unit cable to the 3-way supply connector block (see wiring diagrams on page 3) ensuring that the supplied cable clamp is fitted. Refit the front cover.

Note: When using DTS module on initial connection the fan will start immediately and continue running for the duration set on the timer function of the module.

Front Cover Removal

To remove front cover assembly, first make sure the fan is off, isolated from the power supply and the iris shutter is fully closed

1. Undo the locking screw at the bottom edge of the cover using a screwdriver.
2. Rotate the cover a few degrees anticlockwise until it clicks out from the fittings.
3. Remove the cover by pulling it out.
   

To refit the cover, reverse the above procedure. The iris shutter should be in closed position after refit. If not, wait approximately 1 min after fan switch off allowing the actuator to retract back in the closed position and then refit the cover again.

Module adjustment

A module with Timer and/or Humidistat is supplied pre-set, but may be adjusted by the installer. All adjustments must be done using the supplied Adjustment Tool.

Humidity settings
The humidistat is factory pre-set at approx. 70% RH (relativehumidity). Adjusting the “% RH” towards 40% will result in fan activation at lower humidity (more sensitive). Adjusting the “% RH” towards “90%” will result in fan activation at higher humidity (less sensitive).

Time settings
The Run on Timer is factory pre-set at approx. 15 min. Adjusting the “Timer”towards “MIN” will result in a timer overrun decrease towards 1 or 2 minutes (depends on module). Adjusting the “Timer” towards “MAX” will result in a timer overrun increase towards 30 or 45 minutes (depends on module).
