Obtain a permit to work from the shopping centre management and obtain keys for access onto the flat roof area and access to the plant-room. THESE WORKS ARE TO BE UNDERTAKEN OUTSIDE NORMAL WORKING HOURS Unlock access ladder rung covers and gate to gain access onto flat roof area. Decommission the existing units to be removed (as identified in the photographs below). Isolate and lock-off the electrical supply to entire air conditioning panel at the main isolation switch on the main store incoming distribution board. (Refer to PP-EAW-03) Degas the refrigerant pipe-work and disconnect. Organise Hi-Ab equipped transport vehicle and arrange to have it deliver the new units and take away the old from the service road as shown on the photographs below. Lift the Geni lift onto the roof using the Hi-Ab. Using a Genie lift, hoist units down from their wall brackets and move to the parapet wall adjacent to service road ready for lifting off with the Hi-Ab. Using 2 x soft web slings prepare a ‘Double Bight’ sling arrangement around the underside st of the 1 condenser unit and attach to the Hi-Ab jib hook. Take the load of the condenser on the hook and check for weight distribution. Lower and re-adjust sling positions if required to correct the load balance. Lift the existing condenser units off their supports and directly onto the load-bed of the lorry. Repeat for remaining units. Strip out refrigerant pipe-work not to be re-used to each point of entry into the building. Check and adjust the uni-strut wall support positions to suit the new condenser units. Lift new units into position using the same method of lifting as for their removal. Bolt the new condensers securely into position. Re-install new pipe-work to existing building penetration position through the brick/block wall. Re-install new power and control cabling. Make final connections at the condenser units ready for testing and commissioning following completion of the internal works.

THESE WORKS ARE TO BE UNDERTAKEN OUTSIDE NORMAL WORKING HOURS Take delivery of new equipment and materials in the loading area and move into the building via the service entrance. Using a scaffold tower for access, remove ceiling tiles required to gain access to the connections on each indoor unit and set aside for replacement. Disconnect pipe-work and cable connections from each indoor unit ready for removal. (NOTE: Equipment has been isolated in Activity 2 above) Position the Genie lift beneath to support the weight of the ceiling mounted cassettes. Gain access either side of the genie lift and unbolt rod supports. Lower the unit away from the rods and down to the floor. Move out of the shop and load onto transport using a sack-truck. Strip out the redundant pipe-work and electrical services. Re-install new pipe-work and electrical services on a like-for-like basis, Modify the existing unit-strut and rod supports to suit the new indoor unit. Take delivery and lift into position the new units using the same method. Route pipe-work and cabling along the existing routes. Connect through holes to services installed externally in Activity 3 above. On completion of hot work, report to centre management to sign off hot work permit – EACH DAY. Make final cable connections into the new panel. Charge the systems with refrigerant, test and commission in accordance with the manufacturers commissioning procedure after new panel is made live in the activity that. follows.
