 Remove the cable clamp, connect the power supply (L for hot/Live wire, L2 for neutral and Earth/Ground
to Ground)
 Connect the signal control cables to the indoor units CMI with the terminals N1 - 2 - 3 - Ground (beside).
Make sure that the wiring is in accordance with the indoor units. CMI09, CMI12, CMC12 require min 1,5
mm
2
wire while CMI18 and CMC18 and CMC24 need min 2,5 mm
2
wires
 Fix the wiring with the cable clamps.
 Make sure that the wiring has been connected securely
 Reassemble the lid on the outdoor unit
 Bundle the refrigerant pipes and electrical wire together with tape and wrap them with adhesive tape to
one string. Label this string to which indoor unit it belongs. Caution. Do not wrap too tight for damaging
the insulation. Fix the bundle with clamps min all 1,5 m at wall or ceiling.
NOTE:
 An all-pole disconnection switch having a contact separation of at least 3mm in all poles should be
assembled to switch off outdoor unit in case of an emergency . This switch off shall be in close proximity
to the outdoor unit
 Wrong wiring will cause electrical malfunction and may damage the unit, harm your health and might
even kill you.
 The connection pipes and the connecting wirings of the unit A ,unit B, unit C, unit D and unit E must
correspond to each other respective.
 Do not install the outdoor unit in full sun exposure. This might reduce your cooling capacities. If no other
place appears possible, look for shading. This increases cooling capacity and decreases your power
consumption and the related costs.
 Do not pull the wires when you fix them with the clamps
Mounting
Mount the outdoor unit with heavy and suited bolts on to the ground or an appropriate rack. Perpendicular
ground plates provide four holes for mounting. Make sure that the outdoor unit is assembled safe and
may withstand vibrations, major wind and other weather forces. Wrap all refrigerant pipes and joints.
Drainage of outdoor unit
 When the air-conditioning runs in the heating mode,
the condensate water generated at the outdoor unit
and the water generated by defrosting shall be
drained through the drainage hose to a proper place.
 Installation: Insert the drainage hose into the ø 25 mm
(1”) hole in the base plate of the outdoor unit. Connect
the other end of the drainage hose an appropriate
place to remove all the upcoming water.
13. AIR PURGING AND LEAKAGE TEST
Humid air left inside the refrigerant may cause malfunction of the compressor and needs therefore to be
bled. Refer to the specification for seeing possible combinations of indoor units to outdoor unit. Use only
R410 and do not use mineral oil to clean the pipings and joints. Use suitable instruments.
NOTE: To be carried out only by skilled, qualified and trained personnel with professional
equipment.
