System description
The ACT-7 comprises a room unit and external heat
exchanger. The interconnecting line which connects e two
parts togeer includes two water pipes, condensed waste
water pipe and an electrical supply power cord. Bo ends of
e water pipes are fitted wi ‘quick connect’ couplings at
open on connection but reseal to become water tight on
disconnection. Up to 30m of lines can be joined togeer.
Electrical supply
As standard, 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 at may be used is 2.5mm2minimum
up to a maximum leng of 10 metres. For longer lengs
4.0mm2cable must be used. If e cable is on a ‘cable drum’
en ensure at it is completely unwound in accordance
wi e manufacturer’s instructions – serious complications
will occur oerwise.
Note: Most domestic proprietary extension cables are
1.5mm2. This is not sucient.
Air flow
The air outlet at e top of e ACT-7 room unit is fitted wi
grilles at allow e angle of air outlet to be adjusted. In
conjunction wi e fan speed control switch, e air velocity
and direction can be carefully set up to obtain maximum
coverage of e area being cooled wiout causing draughts.
An alternative top panel wi twin 7" ducts is available.
Care should be taken to avoid outlet air being obstructed as
is will cause e air to rebound around e device resulting
in recirculation and incorrect control of e device. Ideally, e
air should be directed to create a ‘blanket’ of cold air across
e ceiling area allowing natural convection to drop e air
over e whole area at very low velocity.

Ducted fn speed switch
When e ACT-7 is fitted wi ducting, e position of e
ducted fan speed switch inside e ACT-7 room unit has
to be changed. The switch is accessed by removing e
top cover (five screws). The switch is located at e back of
e electric box in e position shown below. Change e
switch to e ducted fan position, and replace e cover wi
e ducted panel. Wi e ACT-7 in is state, when e
fan speed control dial is turned to full speed, e fan speed
display indicator will display red bars (see Controls). If e
ducted panel is changed back to e standard panel ensure
e switch is changed back to e non ducted position.
Siting
Room unit
Ideally, e ACT-7 room unit should be positioned in e
middle of e shortest wall in e room blowing down e
leng of e room. If ere is more an one ACT-7 in e
same area, en ey would normally be positioned side
by side, and equally spaced along e long wall, all pointing
in e same direction. Sometimes it may be necessary to
position units around e perimeter of an area but, in is
case, great care should be taken to avoid one unit blowing
cold air straight into anoer which will adversely affect
operation. Good and correct air flow is, perhaps, e single
most important aspect of satisfactory use of portable air
conditioners. If in doubt seek e advice of your supplier.
Heat exchanger
The external heat exchanger must be sited external to e
area being cooled and, preferably outside. It can stand freely
on a flat surface or may be hung, in e upright position,
from a window-sill or balcony.
Use e chains provided to support e heat exchanger.
(See below).
The heat exchanger must NOT be supported by e
flexible lines alone.

correct position for use wi ducted

ACT-7 QUICK START GUIDE
Condensate
In operation, e ACT-7 room unit condenses water vapour
out of e atmosphere. This water is pumped away rough
e interconnecting line between e room unit and e heat
exchanger. Re-evaporation of some of e water occurs in e
heat exchanger, but water will also drip rough e base of
e heat exchanger.
Consider carefully e potential of dripping water when
positioning e external heat exchanger.
Connections
The ACT-7 room unit must only be operated when
connected to e heat exchanger wi e interconnecting
line provided. Connect e condensate drain to bo e
ACT-7 room unit and e heat exchanger by pushing e
clear hose ends into e grey connector (push darker grey
ring ‘in’ and pull e hose to remove). Connect e heat
exchanger power cord to bo e ACT-7 room unit and heat
exchanger using e sockets provided. Connect e water
pipes to e room unit and e heat exchanger.
The interconnecting line should be routed carefully to avoid
any possibility of kinking or unnecessary restrictions to e
flow of water. The line will be more susceptible to kinking
when warm.
Room unit fluid level
The fluid system in e ACT-7 room unit should be at e
correct level when delivered. Look rough e inspection
window and check at e level is between e MAX and
MIN on e tank in e back of e room unit. If necessary
top up e room unit wi antifreeze (33%) and water. To
ensure e system is properly protected, do not mix different
types of antifreeze. Original specification is eylene glycol
based antifreeze, containing rust/corrosion inhibitors, suitable
for aluminium systems, 33% giving protection to -20°C. This
specification will protect e entire water circuit down to
-20°C (-5°F).
The header tank filler is in e rear of e room unit and
can be accessed by removing e two screws holding e
security plate over e filler tank cap. (See Fig.1).
Ensure e ACT-7 is running in cooling mode before slowly
removing e header tank cap. Top up e tank and replace
e cap and security plate. The approximate total volume of
e system complete wi heat exchanger and lines is as
follows:
Line set leng System capacity
5m 5.3 litres/1.16 gallons
10m 6.7 litres/1.47 gallons
15m 8.1 litres/1.78 gallons
20m 9.5 litres/2.08 gallons
25m 10.9 litres/2.39 gallons
30m 12.3 litres/2.70 gallons
Do not apply mains water pressure to e system.
Refrigerant charge
The device incorporates a hermetically sealed refrigeration
circuit containing 0.88kg of R407c refrigerant.
Global warming potential (GWP) 1774.
Carbon dioxide equivalent 1.6 tonnes.

This alarm resets itself and no action is required on e part
of e user.
When e condensate tank in e ACT-7 is full, a blue bucket
flashes on e console. While is is flashing e ACT-7
continues to work for a furer 30 seconds.
Aer 30 seconds, if e condensate tank has not emptied,

Turning off
If you wish to turn e device off and disconnect e power
supply, switch e device to standby for a minimum of
30 minutes to allow for e condensate pump to drain
e system. The hoses and e mains power can en be
disconnected.
Failure to follow e above procedure may result in
excess water being retained in e system which may
spill when e ACT-7 is moved.
Routine maintenance
The air filter must be kept clean. Never allow e filter to
become obstructed wi dust or dirt. If allowed to do so, poor
performance and component damage may occur. The filter
is fitted to e rear of e panel shown below and is held
on wi magnets. Remove e panel by pushing e panel
up using recesses at e bottom. Remove e filter, vacuum
excess dirt, and wash it wi soapy water. Leave e filter to
dry before refitting it and operating e ACT-7.
