(1) Clear trailer deck of all unnecessary

equipment.

(2) Loosen the 18 bolts securing the front

access cover of the transition area between transformer

and high voltage section, remove cover. (fig. 2-10 and 2-

11).

(3) Loosen and remove the three nuts

connecting the load break switch to the transformer.

Identify and mark each conductor for future hook lip.

(4) Replace and secure the front cover on the

transition area.

(5) Loosen and remove the three bolts

securing the lower front hinged panel, open panel.

(6) On the bottom left just behind heater is a

terminal board. Loosen and remove the two wires coming

out of the conduit connecting high voltage and low

voltage sections.

(7) Close and secure the lower front panel.

(8) Loosen and remove the six bolts and

washers securing the lower rear panel, remove panel.

(9) Loosen and disconnect the conduit in the

lower left bottom connecting the high voltage and low

voltage sections.
