INSTALLATION
Lifting collector to vertical position
UMA 70 to 450 collectors:
A two-point lifting method should be used to lift the collector from the horizontal
to the vertical position. The lifting points are located on top of the collector at
the sides.
The collector must be lifted as shown in figure 4 following the general
guidance to lifting.
Four-point lifting method
The four-point lifting method can be used for all collectors except the UMA 40
and UMA 40MM.
The lifting points are located on top of the collector in all cases except for the
UMA V when fitted with a side outlet box (in this case the lifting points for the
collector are located within the outlet box and are accessed by removing the top
access door).
The collector must be lifted as shown in figure 3, following the general
guidance to lifting. Chains must be long enough to ensure that the
included angle between diagonal chains is not greater than 90°.
Fork lifting method
UMA 40 to 450 collectors:
Remove filter assembly as described in the 'Maintenance' section. If the collector
is fitted with a static earthing arrangement, the earthing bar attached to the seal
frame will also need removing.
The collector can now be lifted by positioning the forks underneath the seal
frame.
Care should be taken not to damage the seal frame rubber seal and the
back of the collector.
The forks used should be long enough to reach the back of the collector
and set as wide as possible. On UMA 40-250 collectors, the forks should
be positioned centrally across the front. On UMA 450 collectors, the
forks should be positioned as shown in figure 5. The collector must be
lifted following the general guidance to lifting.
When replacing earthing bar, ensure earthing strap is reconnected
(collectors fitted with static earthing arrangement).
