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
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
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
unw ound;
serious
exchanger
and
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
all
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.
