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.
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 electrics access side).
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 (Fig.1). Refit the drain tray. Fig.1
CXE PIPEWORK
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.
PIPE CONNECTIONS
Pipework is terminated with 2 flare nuts & bonnets.
Access is via the rear right hand side. Pipes exit the
unit through holes in the back panel.
CONDENSATE DRAIN
Push fit connections are widely available for the 7/8” (22mm) OD condensate drain and 3/4"(19mm) ID drain
stub adaptor. Alternatively 7/8” (22mm) bore plastic tubing may be fitted directly to the stub/adaptor with a
hose clamp. Take care not to over tighten hose clamps as this could damage the stub pipe.
Cables are routed to the terminal block via the cable cord grips at the rear of the unit and then through the
back of the electrics box (see page 2).
• Cables MUST be size compatible with the recommended system fuse.
