Positioning The CX3000 unit is designed for indoor fitting. The unit may be positioned with the side opposite the
connection box up against a rear wall.
1.5.1 Space requirements
CX3000 with hinged
doors (standard)
The cabinet has three hinged doors. The drawing below indicates how much space is needed for
opening the doors and servicing the unit, i.e. changing filters, cleaning, servicing, etc.

See also ● Section "Principal dimensions of CX3000" for additional measurements.
● Section "Maintenance" for information on opening the doors.
1.5.2 Ceiling requirements
When fitting the unit to a ceiling, the ceiling must be:
● flat
● resistant to vibration
● horizontal or sloping towards the condensation outlet
● designed to bear the weight of the unit
1.5.3 Requirements for duct system
Silencers The duct system must be fitted with silencers specified by the Project Manager, which meet the re-
quirements of the operating area.
Insulation The duct system must be insulated to prevent
● condensation
● sound leakage
● heating/cooling losses
Prerequisites Adequate insulation of the duct system in the operating area is a prerequisite for achieving the calcula-
ted sound data during operation.
Condensation Condensation in the ducts may occur when the exhaust air has high humidity. EXHAUSTO recom-
mends a condensation outlet is also fitted at the lowest point in the ducts.
No duct connection If one or more of the inlets/outlets is not connected to a duct: Fit a protective net
to the inlets/outlets with a maximum mesh width of 20 mm.

Pos. Part Function
1 Isolation Switch Connects/disconnects current.
2 Excon Control Control system.
3 Connection box Connection of accessories and power supply.
4 Exhaust Air Fan Removes the stale air.
5 Supply Air Filter Filters the supply air.
6 Additional Condensation Tray "Collects condensed water and drains it from the counterflow
heat exchanger to the condensation tray."
7 Bypass Motor Opens/closes bypass damper.
8 Bypass Duct Directs air around the counterflow heat exchanger.
9 Bypass Damper Opens/closes bypass duct and heat exchanger.
10 Counterflow Heat Exchanger Enables heat exchange between stale and fresh air.
11 Supply Air Fan Blows fresh air into the room.
12 Exhaust Air Filter Filters the exhaust air.
13 Suspention Clamps Clamps for fitting the unit to the ceiling (2 or 3 at each side de-
pending on unit size).
14 Condensation Outlet Pipe Transfers condensed water from the condensation tray. Exter-
nal condensation outlet is connected to it via siphon.
15 Condensation Tray Collects condensed water and drains it from the counterflow
heat exchanger to the condensation outlet.
16 Middle Panel/Door Counterflow heat exchanger cover for inspection and service.
17 Door Sliding doors/hinged doors for inspection and service (Hinged
doors can open left or right side, depending on user’s choice).
1.6.2 Parts of the CX3000 unit
Cabinet The inside and outside of the cabinet is made of galvanized steel. The cabinet is insulated with 50 mm
mineral wool.
Fans The unit contains two centrifugal fans with backward curved blades for exhaust air and supply air.
Counterflow heat
exchanger
The unit's counterflow heat exchangers are made of aluminium and are highly efficient. The counter-
flow heat exchangers can be taken out and cleaned.
Filters The unit includes integral panel filters for both exhaust air and supply air.
Condensation
outlet
The condensation outlet is located on the CX3000 unit door (see previous drawing in this section). The
condensation tray is positioned internally in the door.
Bypass damper The unit has an integral variably adjustable bypass, allowing for precise control of the supply air tem-
perature.
