INSTALLATION
Controller
It is a requirement of the Supply of Machinery (Safety) Regulations 1992
to provide adequate isolation and emergency stop facilities. Due to the
varied nature of site installations this cannot be provided by Donaldson
but instead is the responsibility of the customer.
Always isolate power before opening the controller.
The controller must not be mounted on the side of the collector.
Each Unimaster dust collector can be supplied with a controller, which is designed
to operate the fan and/or shaker in the correct sequence, to ensure that effective
cleaning of the filter fabric is achieved.
The controller contains either a direct-on-line or star/delta fan starter, dependant
on fan size, and a direct-on-line shaker starter. Star/delta versions are standard
for the UMA 750.
Controllers for venting type collectors, contain a shaker starter only.
For controller connections and set-up, refer to Publication IOM AK0303001.
Details of standard fan motor supply voltage are given in Table 6 (refer
to 'Specification' section).
Unimaster optional extras
Castor bases
UMA 40 and 40MM collectors are supplied with the castor base fitted.
UMA 70-250 collectors should be lifted into the castor frame using either the four-
point lifting method or the fork lifting method. No additional fixing is required.
Pressure balance pipe
When this option is fitted, the dust container may be lined with a polythene bag
which can be closed and sealed before lifting out of the container to assist in the
safe removal of toxic or noxious dusts. The containers supplied for this purpose
are fitted with a detachable pressure balance pipe to prevent the bag from being
drawn up into the collector.
To assemble the pressure balance pipe, the following procedure should be
used:
1 Slide the pressure balance pipe over the pipe connection on the dust
container and secure with the hose clip provided.
2 Slide the other end of the pressure balance pipe over the bin balance
spigot assembly on the side of the collector and secure with the hose clip
provided.
