WARNING !
This unit MUST be transported and
operated in the upright position at all times.
1) ELECTRICAL SUPPLY As standard, this
unit requires a 13 amp fused electrical supply
rated at 230Volts, ~1N, 50Hz.
The unit will operate from a standard 13A wall
socket. The size of any extension cable that
may be used is 2·5mm² minimum up to a
maximum length of 10 metres. For longer
lengths 4.0 mm² cable must be used. If the
cable is on a "cable drum" then ensure that it
is completely unwound; serious
complications will occur otherwise.
Note:- most domestic proprietory extension
cables are 1·5mm². This is not sufficient.
2) SYSTEM DESCRIPTION.
PAC15AX/PAC22AX
The system comprises a room unit cooling
section, an external heat exchanger and the
two are interconnected by means of a flow
and return water pipe and an electrical supply
to the heat exchanger fan. The room unit is
fitted with an automatic condensate disposal
pump which discharges the condensate via
a small plastic pipe into the base of the
external heat exchanger and all
interconnecting pipes and electrics are
enclosed in a flexible plastic sheath. In
addition, both ends of each pipe are fitted
with "quick connect" couplings that open on
coupling but reseal to become water tight on
disconnect.
ET15AX
The system comprises, a room unit fitted with
either a fixed or flexible ducting system as
specified by the customer. Condensate is
collected, either in the units internal tank and
emptied by the user or pumped away using
an optional condensate disposal unit.
3) AIR FLOW
The angled air outlets at the top of the
standard room unit are fitted with air grilles
that allow the angle of air outlet to be adjusted
vertically and horizontally and, 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 drafts. An
alternative top pavel with twin 7” ducts is
available. Adjust able grilles and 7” ducts
are not available for machines with a convex
console. Care should be taken to avoid
outlet air being obstructed as this will cause
the air to "eddy" around the unit resulting
in recirculation and short/inaccurate cycling
of the machine. Ideally, cold air should be
directed to create a "blanket" all across the
ceiling area allowing natural convection to
drop the air over the whole area at very low
velocity.
4) SITING
ROOM UNIT. AIR OR WATER COOLED
Ideally, the room unit should be positioned
equidistant along the shortest wall in the
room blowing down the length of the room.
If there is more than one unit in the same
area, then they would normally be
positioned side by side, and equidistant
along the long wall, all pointing in the same
direction. Sometimes it may be necessary
to position units around the perimeter of an
area but, in this case, great care should
be taken to avoid one unit blowing cold air
straight into another which will adversely
affect the machine operation. Good and
correct air flow is, perhaps, the single most
important aspect of satisfactorily applying
portable air conditioners. If in doubt seek
the advice of your supplier.
PAC15AX/PAC22AX HEAT EXCHANGER
The heat exchanger must stand external to
the area being cooled and, preferably, in the
outside atmosphere. It can stand freely on
a flat surface or may be hung, in the upright
position, from a window-sill, balcony, etc,
see Fig 1.
ET15AX
The exhaust tube(s) must carry the air to
an area external from that being cooled,
preferably in the outside atmosphere.

FIG 1
CONDENSATE.
PAC15AX/PAC22AX.
In operation, the room unit is constantly
condensing water vapour out of the
atmosphere (reducing relative humidity).
This water has to be drained away. An
automatic condensate pump is fitted inside
all PAC15AX/PAC22AX room units. The
flexible hose outlet from the condensate
pump runs to the outside, inside the flexible
sheath, the condensate is deposited in the
base of the heat exchanger, considerable
re-evaporation of this water takes place on
the warm air stream passing through and
around the heat exchanger, but please
remember that there will also be a degree
of dripping through the base of the heat
exchanger.
HAVE GREAT REGARD FOR THIS
CHARACTERISTIC WHEN
POSITIONING THE EXTERNAL HEAT
EXCHANGER.
The flexible water pipes should be routed
so as to avoid any possibility of kinking or
unnecessary restrictions to the flow of water
inside. Also, remember that plastic and
rubber becomes much more flexible when
warm and, as a result, much more
USE THE CHAINS PROVIDED TO SUPPORT THE HEAT EXCHANGER. IT WOULD BE
HIGHLY DANGEROUS TO SUPPORT THE HEAT EXCHANGER BY MEANS OF THE
FLEXIBLE LINES ALONE.
susceptible to distortion.
ET15AX.
Condensate from the room unit is collected
in an internal tank and emptied by the user.
An optional pump kit may be fitted to pump
liquid via a plastic tube to an external con-
tainer or the ground. Care needs to be taken
in the positoning of the tube.
5) MACHINE LINK-UP FOR PAC15AX/
PAC22AX
Ensure the mains supply lead to the room
unit is disconnected. A 5m (extendable to
30m) line set to connect all services
between the room unit and the external heat
exchanger will have been supplied. The
water pipe connections are by means of
"quick connect couplers". These are simple
'push-on" connectors which, when
disconnected (after pulling back sprung
loaded locking ring), re-seal the water
system on either side. The complete system
will have been filled with the necessary
amount of water/antifreeze prior to its arrival
on site. A water proof 3 pin quick connect
electrical coupler (push fit with screw lock
ring, hand tight only), and condensate drain

Page 5
pipe coupler 6mm clear polythene (push fit),
should also be connected. Having made the
couplings, the system is operational
immediately.
WACPAC UNITS when required to run as a
normal “PAC” unit need to have the switch
in the recess panel at the back of the unit in
the “1” position. When required to run as a
“WAC” the WACPAC unit is connected to
total loss mains water. When this is done
the switch in the recess panel needs to be
in the “0” position. (Water pump off).
ROOM UNIT WATER LEVELS FOR
PAC15AX/PAC22AX
The water system in the room unit will be to
the correct level when delivered.
However if for some reason the level has
fallen, antifreeze (33%) and water will have
to be added. The header tank filler and level
indication is located to the rear of the room
unit and can be accessed by removing the
two screws holding the security plate over
the filler tank cap, see Fig 2.
Ensure the machine is running in cooling
mode before removing the header tank
cap, and as with all pressure caps,
remove slowly. It is recommended that a
mixture, by volume, of one part antifreeze
to two parts water is utilised, this will prevent
freezing down to an external temperature
of -20°C/-5°F). The approximate total
volume of the PAC system complete with
heat exchanger and lines is shown below.
WAC PAC fluid levels are checked at the
schrader valve in the back of the room unit.

The PAC22MK3 has a third (higher) fan
speed which is ONLY used when the PAC
is fitted to optional ducting. The switch is
situated in the electric box and is
accessed by removing the upper back
panel. It needs to be set to the 3 position.
Use of the switch in this position 3 without
ducting fitted will result in failure of the
PAC, causing blown fuses or burning out
of the fan motor.
