1.
Fit all kits prior to installing the unit. (Heater kit is easier to fit when unit has been mounted).
2.
Ensure that the mounting surface will support the operating weight of the unit (see table below).
3.
Mark out the mounting positions and drill holes to suit 6mm rawlbolt shields or equivalent strength fasteners
(ensure that the unit is positioned to give sufficient access (min 0.5m) to the removable side panel).
4.
Fix the mounting brackets to the unit in the correct position for wall or ceiling mounting.
5.
Raise the unit into position and secure the fixings,
ensuring that it is square and level.
6.
Remove the drain tray then fit the drain stub, nut &
gasket. Refit the drain tray.
NITROGEN CHARGE
The unit contains a small charge of dry nitrogen, which should
be discharged into the atmosphere. This is a non-toxic, non-
ozone depleting gas with no global warming potential.
FITTING LOSSES, in equivalent straight lengths of pipe (m).

A. USING SUCTION AND LIQUID LINES:
With the expansion device connected to the indoor unit, the equivalent pipe run should be 45m (20m for CKC20) maximum,
including a maximum lift of 7.5m. Fully insulate the suction line. Ensure the suction pipe is insulated well over
the drain tray at the indoor unit. Liquid lines should be routed to avoid hot areas. This prevents flash gas
forming, which may result in erratic control of liquid refrigerant to the evaporator.
