Drester Boxer D44C QUATTRO Combi, Operator'S Manual

PLACING THE UNIT

The DRESTER BOXER QUATTRO C 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). If the DRESTER BOXER QUATTRO C is 
installed in locations classified as Zone 2 (or in unclassified locations), the area within a radius of 1 m from the 
DRESTER BOXER QUATTRO C is to be classified as Zone 1, and within a radius of an additional 2.5 m from the unit 
as Zone 2 (total classification: 3.5 m around the machinery and 1 m above it). Within this area, all equipment such as 
electrical items must be approved for the Zones described. Equipment that generates naked flames or sparks (e.g. 
welding or grinding equipment) may not be used in this area. Smoking is not permitted. If in any doubt, contact the local 
fire service authorities for advice.

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 150 litres/
min (6 cfm) of air (450 litres/min (16 cfm) if connected to a DRESTER AIRVENT 11660). 

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
There are three different options for the unit’s ventilation. For all three options, it must be ensured that the speed of the 
air flow at the opening of the hood is at least 0.5 m/s (this corresponds to a ventilation volume of 800 m3/h (500 cfm)). 
The ventilation must be connected in such a way as to ensure the grounding of all parts.

Option 1: Connect the flange of the hood (item 3 illustration 1) directly to a metal ducting, which is in turn connected to 
a ventilation system approved for Zone 1. The ventilation capacity must be at least 800 m3/h (500 cfm).

Option 2: Fit an air-driven DRESTER AIRVENT 11660 to the hood and connect this in turn to a metal ducting. Connect
