6 INSPECTING THE PIPE SYSTEM FOR TIGHTNESS

Start the central unit with all wall inlets closed via the low voltage

connector (gure 1: 8) using a piece of metal wire. If air is still escaping

from the exhaust pipe after approximately 10 seconds, there is a leak

in the pipe system. The leak must be located and repaired. Do not run

the unit for more than 20 seconds with all of the wall inlets closed. If

the installation is completely airtight, the turbine will not receive any

air, therefore overheating and possibly incurring damage. The bypass

valve must be blocked for the duration of the inspection using a piece

of cardboard, for example (gure 2).

7 ACCESSORIES

7.1 PRE-SEPARATORS

Pre-separator EE-20, steel. Product number 80603 / HVAC-code 6901215

Pre-separator EE-20, plastic. Product number 80604 / HVAC-code 6901216

The EE-20 is designed for vacuuming water, sand and coarse rubbish. If the pre-separator is equipped with

a dust bag, the EE-20 also enables the vacuuming of cooled-down ashes and ne dry dust.

Sticky substances and shards of glass may damage the pipe system. The system must

not be used for vacuuming liquids or substances other than normal dust unless a

suitable Allaway-pre-separator is used.

7.2 DUST BAG INSTALLATION KITS

A-series (20l). Product number 81115 / HVAC-code 6901391

C-series (13l). Product number 81114 / HVAC-code 6901390

The central units can be equipped with a dust bag. Dust bag

installation kits are available from all leading retailers. Using a dust

bag is not obligatory, but it is recommended. Detailed instructions

for installation are supplied with the dust bag installation kit.

When using a dust bag installation kit (gure 3), the dust bag is

replaced and the lter serviced as follows:

Remove the dust bag (9), undo the mounting nut (6) located

underneath the lter, remove the dust bag rest (10) and detach

the lter (see section Servicing the Filter).

7.3 FILTER COVER FOR THE CENTRAL

UNIT

Filter Cover, 5 pcs/bag. Product number 80692 / HVAC-code

6901276

The filter cover (figure 4) facilitates cleaning the filter and

lengthens the maintenance intervals and life of the lter. Using

a lter cover is not obligatory, but it is recommended. Never

use a lter cover in central units that are equipped with a dust

bag. Filter covers are available from all leading retailers (sold in

bags of 5).
