System description
The ACT-7 comprises a room unit and external heat
exchanger. The interconnecting line which connects th e two
parts togeth er includes two water pipes, condensed waste
water pipe and an electrical supply power cord. Both ends of
th e water pipes are fi tted with ‘quick connect’ couplings th at
open on connection but reseal to become water tight on
disconnection. Up to 30m of lines can be joined togeth er.
Electrical supply
As standard, th e ACT-7 requires a fused electrical supply (UK
13A, Europe 16A) rated at 230 Volts, ~1N, 50Hz. The ACT-7
will operate from a standard domestic wall socket. The size of
any extension cable th at may be used is 2.5mm
2
minimum
up to a maximum length of 10 metres. For longer length s
4.0mm
2
cable must be used. If th e cable is on a ‘cable drum’
th en ensure th at it is completely unwound in accordance
with th e manufacturer’s instructions – serious complications
will occur oth erwise.
Note: Most domestic proprietary extension cables are
1.5mm
2
. This is not suffi cient.
Air fl ow
The air outlet at th e top of th e ACT-7 room unit is fi tted with
grilles th at allow th e angle of air outlet to be adjusted. In
conjunction with th e fan speed control switch, th e air velocity
and direction can be carefully set up to obtain maximum
coverage of th e area being cooled with out causing draughts.
An alternative top panel with twin 7" ducts is available.
Care should be taken to avoid outlet air being obstructed as
th is will cause th e air to rebound around th e device resulting
in recirculation and incorrect control of th e device. Ideally, th e
air should be directed to create a ‘blanket’ of cold air across
th e ceiling area allowing natural convection to drop th e air
over th e whole area at very low velocity.
