HEYLO FT 1000 Bedienungsanleitung Seite 20

Negative pressurisation: The refurbishment area has to be sealed off from the non-affected areas.
This is done by dust protection wall or film doors. The working area should be kept as small as
possible. Hoses are used to pass the filtered exhaust air from the refurbishment area into the open. FT
1000 can be set up in the refurbishment area as well as in front of the refurbishment area. Let FT 1000
run with negative pressure for the duration of the work without interruption.
WARNING - breathing risk: When operating FT 1000 in a closed area, all power sources to open
fires, such as chimneys, boilers, oven, water heaters and air conditioning units, have to be switched
off in order to reduce the risk of the return of deadly carbon monoxide.
When the change of filter indicator lights up during operation, the pre-filter or the HEPA filter (main
filter) has to be replaced immediately. More information is rendered in the chapters titled "Filter
exchange" and "Maintenance".
Special functions for refurbishing professionals:
FT 1000 has two special functions to assist refurbishment.
1. Adapter sheets for hose connections (diam. 200 mm) can be fitted to the three suction sides (A)
of the unit. Thus, FT 1000 can be set up outside of the enclosed area as well in order to draw off
by means of suction hoses and/or local removal in the black area.
2. By means of bayonet catches, adapter sockets for hose connections (diam. 200 mm) can be fitted
to the two outlet openings (B) in order to pass he purified air from the black area through hoses.
If the area is sealed well, this help building up an effective negative pressure.
Monitor the air pressure using a pressure gauge. Pressure gauges are available from most unit
suppliers.
Suction side (A)
Laying of hoses: The connecting hose of FT 1000 or rather of the entire unit itself has to be laid as
close as possible to the source of the air contamination. With increasing distance of the suction hose
from the origin of the air contamination, the share of air contamination decreases disproportionately.
For improved acquisition at the point of origin HEYLO provides a base stand to hose connection
socket on the suction side. In order to place the hose ends at a higher position, the hoses can be
attached to telescope rods using lashing straps.
Exhaust side (B)
