K1 — Rigging a Kara II Downfill Array with KARA-DOWNK1

Connecting a ground-prepared Kara II downfill array to the bottom of a flown K1 array using the KARA-DOWNK1 interface. Reference: LA-K1-KARA-DOWNFILL-01. Follow in order — this is a sequential rigging procedure, not an independent checklist; steps depend on the ones before them.

Rigging accessory: KARA-DOWNK1.
Minimum 2 operators.
Up to 6 Kara II can be used in this downfill configuration.
Do not implement a pullback on a K1 array with a Kara II downfill.
Prerequisite: a K1 array is prepared and raised; an array of three Kara II with 0° inter-enclosure angles is prepared and positioned under the K1 array.

Rigging a Kara II Downfill Array with KARA-DOWNK1

On each side of the top Kara II enclosure, set the front rigging arm into rigging position by rotating and sliding it down, then secure it with the ball-locking pin. On each side of the top Kara II enclosure, set the rear rigging arm into rigging position: slide the rear rigging arms up and select the same inter-element angle (0° to 10°) as the rest of the array, then secure with the ball-locking pin. Secure KARA-DOWNK1 on top of the Kara II array, positioning its higher ledge at the rear, and secure the four Kara II rigging arms inside the slits with the ball-locking pins. Lower the K1 array as close as possible to the assembly without resting on it. Disconnect the rear ball-locking pins between the two top Kara II enclosures and place them in storage position — risk of crushing injury, keep fingers away from the contact area between the ledge and the cabinet; risk of cable damage, disconnect any cable from the K1 bottom connector first. Connect KARA-DOWNK1 to the bottom of the K1 array: rotate the top Kara II upward and secure the rear KARA-DOWNK1 tabs to the K1 rigging, secure the front KARA-DOWNK1 tabs to the K1 rigging (slightly lower the K1 array if necessary), then reconnect the top Kara II at the rear to the assembly using the handles of the bottom Kara II. Raise the array. Set the inter-enclosure angles. Repeat the rigging arm, KARA-DOWNK1, and angle-setting steps until the Kara II array is complete — refer to the Kara II owner's manual for its own angle-setting details.
