B. WIRING.

WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE

ISOLATED FROM THE POWER SUPPLY DURING THE INSTALLATION /

OR MAINTENANCE.

IMPORTANT: The controller is only suitable for connection to a 220-240V 50Hz AC

single phase mains electrical supply. It is double insulated (CLASS II)

and therefore must not be earthed. It provides a 12V 50Hz AC Safety

Extra Low Voltage for the Solo Pro SELV range of fans. Note that

only one fan must be connected to the controller.

1.5mm² wire is recommended for cable runs up to 8m.

1. Select and follow the appropriate wiring diagram. (Fig. 1, 2 or 3)

2. Check all connections have been made correctly and ensure all terminal

connections and supply wires are securely fastened using cable clamp provided.

3. Ensure the impeller rotates and is free from obstructions once reassembled (Fig. 4

and 5).

C. SETUP

WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE

ISOLATED FROM THE POWER SUPPLY DURING THE INSTALLATION /

OR MAINTENANCE.

Timer adjustment (SVT)

BEFORE ADJUSTING THE TIMER, SWITCH OFF THE MAINS SUPPLY. TIMER

SHOULD ONLY BE ADJUSTED BEFORE OR DURING INSTALLATION.

1. Unscrew the fixing screws on the cover of the controller. The fan overrun period

can be adjusted up or down using the pot located on the internal PCB.

2. To REDUCE the operating time, use a small screwdriver to turn the pot ANTI-

CLOCKWISE.

3. To INCREASE the operating time, use a small screwdriver to turn the pot

CLOCKWISE.

4. Replace the controller cover.

TIMER ADJUSTMENT (SVHTP, FIG. 4 AND 5)

BEFORE ADJUSTING THE TIMER, SWITCH OFF THE MAINS SUPPLY. TIMER SHOULD

ONLY BE ADJUSTED BEFORE OR DURING INSTALLATION.

1. Remove the fan and PCB covers and the impeller (Fig. 4 and 5). The controller is

factory set at 15 minutes approx. The overrun period can be adjusted from 3-25

minutes by altering the pot on the control PCB.

2. To REDUCE the operating time, use a small screwdriver to turn the pot ANTI-

CLOCKWISE.

3. To INCREASE the operating time, use a small screwdriver to turn the pot

CLOCKWISE.

4. Replace the fan and PCB covers and the impeller.

HUMIDITY SET-POINT ADJUSTMENT (FIG. 4 AND 5)

BEFORE ADJUSTING THE CONTROLLER, SWITCH OFF THE MAINS SUPPLY.

HUMIDISTAT SHOULD ONLY BE ADJUSTED BEFORE OR DURING INSTALLATION.

1. Remove the fan and PCB covers and impeller. The controller is factory set to

switch on at about 70% RH. The humidity set point can be adjusted from 40-

95%RH by altering the adjuster on the control PCB.

2. To LOWER the set-point use a small screwdriver to turn the adjuster ANTI-

CLOCKWISE. This makes the controller MORE sensitive.

3. To RAISE the set-point use a small screwdriver to turn the adjuster CLOCKWISE.

This makes the controller LESS sensitive.

4. Replace the fan and PCB covers and impeller.

IMPORTANT: Upon installation it is possible that the humidity controller will make the fan run

continuously until it has acclimatised to the environment. As part of the installation process it is

important to set/adjust the humidity sensitivity to the desired position. The controller is already

factory set to switch on at about 75% R.H.

PULLCORD OPERATION

The PULLCORD will activate the fan when switched. When the PULLCORD is switched into the

off position the fan will deactivate. The SVHTP model will return to the Auto sensing mode.

D. SERVICING AND MAINTENANCE.

WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE

ISOLATED FROM THE POWER SUPPLY DURING MAINTENANCE.

1. At intervals appropriate to the installation, the fan should be inspected and cleaned to

ensure there is no build-up of dirt or other deposits.

2. Carefully pull the front panel off the inner grille. (fig.4.)

3. Wipe the inlets and front face with a damp cloth until clean.

The fan has sealed for life bearings, which do not require lubrication.
