6. POWER & CONTROL CONNECTIONS Cont
6.1 Wiring-up the Unit
Electrical terminations should be made onto the screw terminal side of the outdoor unit terminal blocks.
6.2 Wiring Requirements
Power supply – Connection of isolation power supply to the outdoor unit. Interconnecting Wiring – Power and signal cables run between outdoor and indoor unit.
Details of the fuse ratings and cable requirements are given in the tables in Section 5 Page 7, of this manual.
Note: On units with 3-phase power supplies, ensure the 3 phases are connected in the
correct rotation ie L1, L2, L3. If the phase rotation is incorrect, the compressor will fail to pump and will likely be noisy. If this is the case, two phases will need to be swapped over to achieve correct rotation.
6.3 Terminations
Details of cable terminations and interconnections are given in Table 6.1.
6.4 Wiring Diagrams
These are fitted to the inside of the access door.

7. REFRIGERANT PIPE CONNECTIONS
Figure 7.1 – Refrigerant Pipe Connections
7.1 Expansion Device
ICU Cooling Only Units DO NOT HAVE an expansion device as this is supplied with the indoor unit. ICU Heat Pump Units can be supplied with a separate expansion device kit that should be installed in
the liquid line.
7.2 Pipe Installation
Run the suction and liquid lines in appropriately sized refrigeration copper tubing, using the detailed tables on pages 11 & 12 of this manual as a guide. When calculating the effective run take into account any bends or oil traps as described in table 7.1 on page 12. A filter drier and site glass should be fitted in the liquid line. Where the vertical separation exceeds 3 metres, oil traps must be fi tted at half the vertical distance as shown on Figure 7.1 above. Ensure the refrigerant lines are adequately supported using refrigerant pipe clips. ICU170 units are supplied with a length of 7/8” od flared pipe to assist connection to shut off valve.
7.3 Unit Connections
The ICU unit connections are terminated in male flare connections as detailed in the tables in Section 5, page 7, of this manual. Place flare nuts onto the copper tube before pre paring the tube with a flaring tool (7.1C). When connecting to the male flares ensure both surfaces are clean and coat the flared surface with refrigerant oil to help ensure a leak-free joint. When tightening the joint use two spanners to prevent twisting of the connections as detailed in figure 7.1B above.
7.4 Insulation
Suction lines must be insulated to a minimum thickness of 3/8”. Hot areas should be avoided when routing liquid lines and consideration should be given to separate insulation of liquid lines, where required, to prevent heat absorption.
SPECIAL NOTE
SLEEVE, SEAL AND WATERPROOF ANY BUILDER WORKS HOLES!
IT IS RECOMMENDED THAT A FILTER / DRIER IS FITTED IN THE REFRIGERATION CIRCUIT.

8. REFRIGERATION COMMISSIONING
Figure – 8.1 Evacuation and Charging Connections
8.1 Evacuation, Charging and Refrigerant Procedures
After completing the refrigerant connections the following steps should be followed with reference to Figure 8.1 above.
1) Service gauges - Connect the low pressure port (1) of a manifold gauge set to the suction line
outdoor unit shut off valve service port (2).
2) Vacuum Pump - Connect the centre line port (3) of the manifold gauge set to the vacuum pump (4)
and operate the pump to ensure a vacuum of 200 microns.
Note: Ensure gauge low pressure port (5) is open and high pressure port (6) is closed.
3) System Isolation - After achieving the specified system vacuum close the gauge low pressure port (5)
and switch off the vacuum pump. Leave the system for 1 hour and check that the vacuum is maintained. If not, check for leaks, rectify and repeat the pumping down to 200 microns.
4) Refrigerant Charging - Open both the outside unit shut off valves (7 & 8). Weigh in the appropriat e
charge using a charging station.
5) Disconnect the vacuum pump and connect the gauge high pressure port (9) to the discharge line of
the outdoor unit shut-off valve (10), ensuring that the gauge central port (3) is closed. Run the system, allow pressures to stabilise and ensure correct operation. After final commissioning remove the gauge set, fit all valve caps and carry out a final refrigerant leak test.
This being a stand-alone condensing unit, the match to the indoor unit and appropriate charge are the responsibility of the installer.
