Champion Compressors Ltd. Manual No. 975203 Rev H
25
When incorporated with the Clean Air Pack, the receivers will operate in a ‘wet
and dry’ configuration, i.e. two individual receivers separated by dryer /
filter(s). Discharge air enters the ‘wet’ receiver where some condensation
takes place, additional filtration is provided by the dryer / filter(s) before
entering the ‘dry’ receiver. An additional filter may be fitted at the discharge of
the ‘dry’ receiver.
The Dirty Environment Filter and Acoustic Hood (Ci 40 / 55) options are
available in conjunction with the Duplex option.
9.9 Base-mount
Where an air receiver or equivalent exists at the installation location, a
Dominator may be ordered without an integrated receiver. The pressure
switch is supplied loose (on a 2m fly lead) to be fitted into the air supply to
provide a control signal for correct compressor operation.
9.10 Sump Heater and Thermal Fan
A sump heater is available to enable the machine to stay warm when not in
operation and to prevent condensation from mixing with oil. This option is
advisable in the cases of a low load cycle, low ambient temperature and a
humid environment. The sump heater option requires a dedicated 240V
connection.
The thermal fan switch option is designed to suit machines with very low load
cycle operation. A temperature switch monitors oil temperature and only
switches the cooling fan on when the oil is at a minimum temperature. This
ensures the compressor achieves desired operating temperatures within a
minimum time.
9.11 Auto Restart Option
The auto restart option allows the machine to automatically restart after a 30
second delay upon the reinstatement of power following a power interruption.
9.12 Phase Failure Relay (Ci 75/110 only)
The phase failure relay option can be fitted to provide protection against
phase imbalance, phase dropout and incorrect phase sequence.
