Installation process
1. Remove all packaging and covers
Note All outer metal surfaces are covered by a
protective plastic film, which must be removed
before final fixing and operation of the unit.
2. GS units, Loosen (DO NOT REMOVE) the screws
in the top of each front inlet cover [1] (see figure
9.1and 10 dog bone slot) then slide the left
cover to the left [2] which will allow the cover to
slide under the end cap. This will allow the next
cover to be pushed to the left [3] (see figure 9.1)
allowing it to be released from the screw slot [4]
by pulling forward and lifted upwards out of the
lower grove in the case.
3. The first cover can then be pushed to the right
to release it from the screw slot, (see figure
10) then pull forward and lift upwards to be
removed. For additional covers fitted on the
1500 or 2000 units loosen the fixing screws and
remove as with the previous covers.
