Installation manual
Connection to the Electricity Supply
It is a requirement of Seeley International that all coolers be wired with a dedicated circuit to the
distribution board adhering to Local and National wiring standards. Ensure that the power supply
corresponds to the rating indicated on the serial plate.
RPB600-1000 coolers have either 25mm diameter knockouts or holes in the corner pillars and
side panels, use one of these holes for the conduit entry. Wire the unit in accordance with the
wiring diagram supplied and the local supply regulations.
RPB1200-1800 ) have a separate mains isolator located on a corner pillar. Wire the mains power
to the isolator.
Mounting the Control Switch - Mount the control switch in the most desirable location.
Two Speed Three Phase Units
Controls for two speed air conditioners are 240 Volt Clipsal switch plate pattern.
No adjustment of minimum or maximum speed is necessary.
Control circuit wiring is via a 240V 5 wire system.
Wire the unit in accordance with the wiring diagram supplied and the local supply regulations.
Electrical Connection.
If turning pulley counter clockwise to reduce
blower speed, be sure that the V section is not
opened far enough to allow the belt to ride on
the threaded part of pulley, as this will cause
damage to the belt.
Too great a belt tension will increase
motor load, and shorten belt and bearing life.
Too loose a belt will cause belt slippage and
excessive belt and pulley wear.

Check the Full Load Amps
After any adjustments to belt tension, the maximum full load current must be checked
to ensure it is within the rating specified on the serial plate. If the amps are not within
rating, make adjustments to the motor pulley as described in this section. Only units
with a variable pitch pulley can be adjusted, other units need to have the fixed
diameter motor pulley changed.
Check that the full load current on high and low speed is within the motor rating.
