8. SYSTEM MAINTENANCE

FILTRATION SYSTEM

In order to maintain good air quality in your home, the power unit is equipped with a fi ltration

system. It consists of a permanent fi lter and an optional disposable fi ltration bag. The fi lter

separates dust from the air. The fi lters refi ne the fi ltration process retaining extra fi ne dust

particles, as minute as 0.1 micron (the diameter of one hair is approximately 60 microns).

ermanent

iLter

Duovac's fi ltration system will maintain its high performance as long as it is well looked after.

The permanent fi lter can be machine-washed and tumble dried.

A natural protection (GREEN) against odour-causing

bacteria, SILPURE exploits the natural power of silver in

stopping the growth of a wide range of bacteria. It is

recommended that the dust canister be emptied every three

(3) months or more often depending on the use you make of

your system.

IMPORTANT

DO NOT vacuum gypsum dust, fl our, mud, or any sludgy materials as they cake onto

the fi lter and obstruct the fi ltration system resulting in the overheating of the

motor and thus failure of the power unit to function properly;

not using

If you are

a disposable fi ltration bag in addition to the permanent fi lter,

empty the dust canister regularly to ensure a longer-lasting life of the motor.

using

If you are

the disposable fi ltration bag, it should be checked / changed as

often as you would empty the dust canister.

While emptying the power unit's dust canister, the permanent fi lter should also be cleaned:

Unlatch the dust canister;

1�

Wrap a plastic / paper bag around the fi lter and gently pat the fi lter to dislodge any loose

2�

dust into the bag.

Empty the dust canister into a garbage bag.

3�

NOTE

We recommend that the permanent fi lter be deep-cleaned once a

year;

a� Remove the dust from the lter by gently patting it into a bag as

mentioned above;

b� Remove the lter by pulling it down;

c� Drop it into the washer.

d� Set the washer to a normal wash cycle (warm or cold water) then,

spin dry (regular cycle) for 10 minutes;

e� Before replacing the lter, clean the inside of the ltration cage;

IMPORTANT

Do not turn fi lter inside out. It must be replaced over the cage on the same fabric

side as initially mounted in the factory.

It is very important that the fi lter be slipped over the metal rim located at the top of

the cage. In order to prevent any dust infi ltration into the motor, the cage must be

completely covered by the fi lter;

f� Clip the dust canister back onto the casing.

iSPOSaBLe fiLtratiOn Bag

In order to maximize your system's fi ltration capabilities, all Duovac power units (except

the SIG-200) come with a disposable fi ltration bag. See below instructions on replacing the

disposable fi ltration bag depending on the system being used:

The disposable fi ltration bag must be changed at least every 3 months to ensure proper

functioning of the power unit.

To change the fi ltration bag, please proceed as follows:

Unlatch the dust canister;

1�

Remove the disposable bag from the elbow attachment by gently pulling on both sides of

2�

the cardboard cuff ;

Dispose of the used bag;

3�

Slip the new disposable fi ltration bag onto the elbow fi xture by gently pressing on both

4�

sides of the cardboard cuff until it reaches the stop notch on the elbow.

IMPORTANT

The warranty will be void if non-recommended fi lters are used to repair the unit.

Duovac recommends strongly to use only Duovac certifi ed fi lters.

MOTOR

All units are equipped with a soft-start control module and have a LED communicating the

system status (see fi g. 5 in section 9 for more details on LED colour interpretation). When the

LED changes to amber, it is time to make an appointment with a Duovac certifi ed technician for

a complete check-up of the unit. This mandatory maintenance will extend the life of the unit

and keep the warranty valid. If it is still not carried out after 20 hours of additional operating,

the device will automatically switch off as a safety measure.

All systems also have a mini breaker (power cut-off ) directly connected to the module which

protects the motor against an overload and prevents overheating.
