Installation and wiring instructionsfor WHS100B Whole House System

PRODUCT DESCRIPTIONThe Silavent Whole House Heat Exchange System is designed to extract from up to three rooms and replace the extractedair with new fresh air via one central inlet grille. To facilitate this, the whole house system is fitted with a unique control unitthat allows for three switch lives to be installed.

The whole house system fans are constructed from tough ABS plastic, mounted to a central powder coated Zintec body.The motors are external rotor type, fitted with long life ball bearings and mounted on flexible rubber mounts to reduce anyvibration transmission. The inlet and outlet ducting connects via easily fitted 100mm manifolds to allow for ease ofinstallation and servicing.

OPERATIONThe whole house system fans are designed to run continuously on slow speed. When any one of the three room lightsconnected to the whole house system are switched ‘on’ via the ‘switch live’ operating switches shown in diagram 1, thewhole house system will switch to high speed running.

When the ‘switch live’ operating switch is switched ‘off’ the whole house system will continue to run at high speed for aperiod of between 2 minutes and 30 minutes dependent on where the timer adjuster in the extract fan is set (Factory set atminimum) then the whole house system will revert to running in the continuous slow speed mode.

INSTALLING THE WHOLE HOUSE SYSTEMWe recommend that the whole house system unit be screwed firmly into position in the attic/loft above the hall, bathroomor airing cupboard to prevent any operating noise being transmitted into the bedrooms. Additional optional foam feetstandoff’s are also provided for fitting under the metal feet of the system if required.

Ducting runs should be kept as short as possible to ensure low operating pressures. If extracting from wet rooms, provisionshould be provided for condensation by leaving a ‘Low’ point condensation trap in the ducting. If the installation is in theattic/loft we recommend that ducting should be insulated.

CONNECTION OF DUCTING TO THE SYSTEMTo connect the ducting to the extract side of the system unit (Adaptors ‘A’ ‘B’ ‘C’ on Figure 1) three adaptors are suppliedfor terminating the flexible ducting, these should be glued or taped onto the ends of the ducting or secured with theadjustable ‘TIE WRAPS’ provided with Silavent Flexible ducting.

The three way manifold plate should be removed from the system by releasing the quick release mechanisms situated atthe bottom of the right hand side fan unit. The adaptors are ‘Push Fit’ onto the three way manifold plate and retained usingthe self tapping screws supplied, the manifold plate can now be fitted back in position on the right hand side fan unit.

NOTE: Do not glue the adaptors onto the manifold plate.

The extracted air is exhausted to the outside via the ducting connected to the left hand outlet (’X’ on Figure 1) and the newor fresh air is directed to the return grille via ducting connected to the right hand outlet (‘Y’ on Figure 1).

When the whole house system is firmly fixed in position and the ducting connected, the wiring should be istalled asdetailed on wiring diagram Figure 2.

Installation and wiring instructionsfor WHS100B Whole House System

WIRING INSTRUCTIONSThe Silaven whole house system will extract from up to three inlet sources. To facilitate independent switching, the systemis equipped with three switch lives, therefore allowing operation from up to three rooms.

ISOLATE POWER SUPPLY BEFORE COMMENCING WORK.

IF IN DOUBT CONSULT A QUALIFIED ELECTRICIAN.

NOTE: THE POWER SUPPLY FOR THE SYSTEM MUST BE FROM THE FUSED CIRCUIT.

The minimum wiring requirement is:

Permanent Neutral, Permanent Live and One switch live. One or two extra switch live may be added as desired. It does notmatter in which order the switch lives are connected or operated.

The ‘Run On Timer’ adjustment within the right hand fan unit is as follows, turn the adjuster anti-clockwise for less overrunor clockwise for more overrun.

WIRING REQUIREMENTThe system should be connected with fixed wiring to the power supply via a cable with solid conductors of 1 to 1.5 squaremm only.

It is recommended that the wiring should be connected to the power supply with Double Pole (3mm) isolation and suitablyfused in accordance with IEE regulations. IF IN DOUBT CONSULT A QUALIFIED ELECTRICIAN.

To gain access to the system wiring terminal block, remove the two screws on the top of the front cover of the right handside fan unit then remove the front cover.

The system wiring should access the unit through the grommet (‘Z’ in figure 1) in the right hand fan unit.

Wire the whole house system to the power supply and the three room lights as shown on wiring diagram Figure 2.

When the wiring is complete, replace the front cover of the right hand fan unit and retain by replacing the two cover fixingscrews. The whole house system is now ready for use and be tested as follows :

Close the Double Pole insolation switch and the system will run continuously on slow speed, operate any one of thethree room light switches and after a slight delay the system will run on fast speed. Switch the room light switch off,the system will continue to run on fast speed for approximately 2 minutes then revert to running on slow speed.

NOTE: FANS INCORPORATING ELECTRONIC CONTROLS MAY BE DAMAGED IF USED OR CONNECTED INTOCIRCUITS SUPPLYING FLUORESCENT LIGHTING.

Typical Installation

SERVICING THE WHOLE HOUSE SYSTEM

WARNING : ISOLATE THE POWER SUPPLY BEFORE SERVICING AND CLEANING THE SYSTEM.

The whole house system should not require any mechanical components servicing, but it will require annual cleaning toensure a long and effective service life.

Remove the four screws on the centre top cover and remove the top cover. Carefully remove the matrix section from themain housing unit. The matrix unit should be cleaned of any dust or debris that may have collected, when clean, replacethe matrix in the main housing unit ensuring correct orientation by lining up the postion indicators adjacent to each otheron the top faces of the matrix and inner cover. A vacuum cleaner is a good method of removing dust and debris from thematrix section and inside the main housing unit.

Remove the front covers from both the right and left hand fan units by removing the two fixing screws in each cover, thefan impellors can be cleaned using either a dry brush or a vacuum cleaner. Prior to replacing both the front covers, checkthe terminal block wiring for loose or dislodged wiring. Replace the front covers and secure using the two fixing screws ineach front cover.

Remove the front grille’s from both the right and left hand fan units using the quick release mechanisms then remove thefilter’s. The filters can be cleaned using a vacuum cleaner and the grille’s wiped with a damp cloth. When cleaned, replaceboth the front grille’s.

Finally, check that all ducting connected to the system and inlet/outlet grille’s is intact and secure.

IF ANY DOUBT EXISTS WITH SERVICING THE SYSTEM, WE SUGGEST YOU CONTACT OUR CUSTOMER SERVICEDEPARTMENT.

WARNING:

Failure to comply with the installation instructionsand cautionary notes may invalidate the warranty.
