1.Before connecting the head

Checking the flash tube (B1), model lamp (B2) and Pyrex (B8)

To ensure that the flash tube and model lamp are well inserted:

•remove the Pyrex shell by gently pulling on it. Press the wheels (B6) with your finger to help removing the shell.

•check that the model lamp is properly screwed in, without touching the glass portion of the lamp. If your fingers touch the glass of the model lamp, clean the model lamp using a cloth and alcohol.

To remove (or replace) the model lamp, you must first remove the flash tube.

Use the standard 250W model lamp or up to 500W maximum if the accessory and the flash unit can handle it.

•if necessary, remove the flash tube by pulling on it (there are no screws to unfasten). Flash tubes are polarized (+ and -) with different connector sizes. It is therefore impossible to insert a flash tube backwards. Note that one of the connectors is loose to relieve pressure on the glass due to dimension tolerances, heat dilatation and travel.

•make sure the trigger wire (B3) is properly inserted into the glass tube (B4), with its round section in firm contact around the side of the flash tube. Squeeze the trigger wire prior to insertion if necessary.

•remount the Pyrex shell by inserting it until the 3 holding wheels cover the shell rim.

Mounting a second flash tube

A second flash tube can be mounted in a cross position (C).

•both tubes must be of the same type.

•the second tube is inserted above the first one.

•a second trigger wire might be necessary for certain flash tube models (e.g. L-HD) if the trigger wires of both flash tubes are not in contact with each other. If so, insert the second trigger wire in the glass tube (B4), together with the first one, each connected to each tube.

Checking the mounting system

Make sure the Pan/Tilt handle is tightly mounted onto the unit. Mount the unit on a stand of sufficient weight and span to guarantee the stable operation of the unit.

Checking the connector

Make sure the head connector pins are not damaged. Also check the unit connector. Any damage to the connector pins is not covered by warranty.
