Operation without connected heat exchanger provokes an HP failure
and can damage the recirculation pump
If the ACT 7 room unit is operated in air conditioning mode while the heat
exchanger is disconnected, the room unit will enter a high pressure state
and automatically shut down the unit. There is a risk of damaging the
recirculation pump.
• The ACT 7 room unit must only be operated (specifically in Air Condi-
tioning mode), when connected to the heat exchanger with the interconnecting line
provided.
The air outlet at the top of the ACT 7 room unit is
fitted with grilles that allow the angle of air outlet
to be adjusted.
In conjunction with the fan speed control switch,
the air velocity and direction can be carefully set
up to obtain maximum coverage of the area being
cooled without causing draughts.
NB: An alternative top panel with twin 7" ducts is
available.
If the air flow is blocked an HP or LP failure can be provoked and shut down the unit
• Never put anything on top of the device or block the air in- and outlets.

Fig . 4: Care should be taken to avoid outlet air being obstructed as this will cause the air to
rebound around the device resulting in recirculation and incorrect control of the device.
Fig . 5: Ideally, the air should be directed to create a 'blanket' of cold air across the ceiling area
allowing natural convection to drop the air over the whole area at very low velocity.
