Fit to liquid connection on the CXE 70 indoor unit 
when matched with a CKC 60 outdoor unit 

The unit may be mounted on a wall or solid ceiling using brackets supplied. It should be matched with the appropriately 
sized outdoor unit; this instruction should be used in conjunction with the outdoor unit installation instructions. 

UNIT COMBINATIONS 

 

 

 

 

 

 

 
 
 
 

 

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).

 

 

 

FITTING

 

Pipe Size OD

 

To  calculate  the  total  equivalent 
length, the equivalent lengths of all 
fittings in a pipe run must be added 
to  the  actual  length  of  pipe  in  the 
run:  these  are  the  fittings  most 
likely to be used.  
 

R = Radius of bend 
d = Diameter of tube

A. USING SUCTION AND LIQUID LINES:

 

 
With the expansion device connected to the indoor unit, the equivalent pipe run should be 20m 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.
