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.
