Page 13: Pipework
CKC PIPEWORK Individual pipe runs to a maximum of 20m, including 7.5m lift, are permissible with liquid lines, 80m with expansion lines, provided good refrigeration practice is followed. Performance is based on 7.5m pipe runs. Correctly sized pipes for each installation will result in no significant loss of capacity on extended pipe runs. - Page 14 USING SUCTION AND EXPANSION LINES The expansion assembly must be removed from the indoor unit and connected to the outdoor unit allowing a pipe run of up to 80m, including a maximum lift of 20m. Fully insulate both the suction and expansion lines, including the expansion device: ensure the pipes are insulated well over the drain tray at the indoor unit.
- Page 15 PIPE CONNECTIONS Units are supplied with the following male flare connections (sizes in inches): Model Size 50 80 90 100 130 150 165 180 Expansion 3/8 1/2 1/2 1/2 1/2 1/2 1/2 1/2 Suction 1/2 5/8 5/8 3/4 3/4 3/4 3/4 7/8* CONNECTING THE UNITS Ensure both service valves on the unit are closed (clockwise) before commencing installation.

Page 18: R407C Refrigerant
R407C REFRIGERANT Charging the System: Evacuate the system and interconnecting pipework ensuring the service valves are fully open. Allow the evacuated system to draw in the majority of the refrigerant charge. The final charge should be adjusted with the system running. All units are fitted with head pressure control. -
Page 19: End Of Life Requirements
END OF LIFE REQUIREMENTS Refrigerant must be recovered by a certificated technician before the plant is dismantled. Modern refrigerant recovery machines should be able to remove well over 95% of the refrigerant in an old system. All recovered HFC refrigerants can either be: a) Sent for destruction by incineration at a licenced waste facility b) Sent to a specialist plant that can re-process the old refrigerant into a gas with properties identical to virgin refrigerant, to create “reclaimed refrigerant”... - Page 20 CXE INDOOR UNIT COMPONENT IDENTIFICATION Grille De-ice stat (option) Fan / motor Heater assembly (option) Case Drain stub adaptor Wall / ceiling mounting brackets Drain tray Heater bracket Side access panel Coil assembly Electrics box door Thermostat bulb & bracket Digital display (option) Restrictor assembly / extended pipe (option) 55908039-06...
