PLACING THE UNIT
DRESTER BOXER DOUBLE A is equipment Category 2 (ref. ATEX-directive 94/9 EC) and may therefore be placed in
locations classified as Zone 1 (ref. ATEX-directive 1999/92 EC).
Make sure that the unit is properly grounded by using the grounding cable (item 6 illustration 2).
This manual is part of the unit and must be available at all times.
INSTALLATION
Compressed air
The unit must be connected to compressed air of 7-12 bar (110-180 psi). When in use, the unit consumes 250 litres/
min (9 cfm) of air.
The air is to be connected to the moisture trap inside the unit (item 1 illustration 2). To access this point, remove the
front panel (item 5 illustration 1) by lifting it up-and-out.
The air-line can be led into this point via the slots on the side of the unit, or through the open back of the unit. In either
case, make sure that the air-line do not bend the hoses or in any other way harm the pneumatic system of the unit.
To prevent pressure drops, the air line and couplings must be adequately dimensioned. The regulator on the unit is pre-
set to 6.5 bar (100 psi). This is the optimal setting and must not be altered.
The compressed air supplied to the unit must be clean and dry. If it is not first led through a water trap and filter, it may
cause damage to the pneumatic components of the unit, which will invalidate any warranty claims.
Fit a connector to the air-line on the left side of the unit (item 4 illustration 1). This air-line is intended to blow out the
spray-gun after the cleaning procedure.
Tap-water connection
Connect a hose for tap water to the water inlet connector (item 13 illustration 2).
The hose can be led into this connector via the slots on the side of the unit, or through the open back of the unit. In
either case, make sure that the hose do not bend the air-lines or in any other way harm the pneumatic system of the unit
Drain hose
Connect a drain hose to the drain outlet connector (item 12 illustration 2). Lead it on to, and secure it well to a regular
drain-water system.
The hose can be led into this connector via the slots on the side of the unit, or through the open back of the unit. In
either case, make sure that the hose do not bend the air-lines or in any other way harm the pneumatic system of the unit
Ventilation
The air-driven extractor must be connected to a metal ducting to lead the exhaust outdoors. An alternative is to lead it
into a hood that is in turn connected to a suitable ventilation system approved for Zone 1. This hood should have an
open design so as to avoid constant extraction (see illustration 10).
The metal ducting may not be longer than 15 metres, and must be connected in such a way as to ensure grounding.
PERMITTED SOLVENTS
The unit has two separate areas for cleaning:
14. The automatic washer (item 1 illustration 1). In this washer water or water-based solvents can be used.
