Pressure relief
The manifold has a maximum operating pressure of 6.2 bar (see Table 4 in ‘Specification’
section). It is a requirement that adequate precaution is taken to avoid exceeding
this pressure. Where a relief valve is supplied by Donaldson this device has a relief
rating of 17 dm³/s at 6.9 bar. Extra system relief will be required if the connected
supply can exceed this.
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.
Each CPC dust collector is supplied with a Controller or a Power Box to operate the
compressed air cleaning system. The Power Box also operates the fan.
For Controller connections and set-up, refer to Controller manual.
The optional Power Box is supplied separately on CPC-6, CPC-8 and CPC-12 collectors.
The Power Box can be attached to either side of the collector using the controller
location panel and fixings supplied (refer to Figure 6).
The Power Box must be fitted on the opposite side to the explosion panels
on CPC-6, CPC-8 and CPC-12 collectors fitted with explosion relief.
