1613 A/C 1-1 Coolant fault, to rectify ~~~~~ 1613 A/C 1-1 Coolant fault, to rectify.  1613 A/c 1-1 TIMS showed 'COOLANT FAULT',unable to reset. Checked system pressure & found no pressure. Performed freon charging but no suction. Notification 2444584 raised to RSW for #1613 A/c 1-1 CCU C/out. Found leakage at LP gas pipe couplingbetween pipe & poppet v/v. Tightened coupling but leak persisted. Notif 2444599 raised to HM to replace #1613 A/c 1-1 LP gas pipe (25mm dia.) & coupling between elbow joint & poppet v/v. Notif 2444601 to CSC to service #1613 A/c 1-1 leakage at poppet v/v suction side coupling to CCU.
