8.) Connect to AC service.
CAUTION: Once connected to site electrical service lethal voltages are present inside the unit. The
AC power is present at the circuit breaker, main contactor and isolation transformer. In addition, the
isolation transformer secondary outputs are hot. Review and understand the safety subtopic in
Section 5 before proceeding.
The system can be hard wired to electrical service, but is more typically connected by a plug to an
electrical outlet.
If the system is to be hard wired, the customer must provide an electrician to wire the cord end into
the electrical service outlet.
If the system is to be plugged into an electrical receptacle, the appropriate receptacle should already
be installed by the customer's electrician. The installing engineer connects the plug to the end of the
VersaPulse Select electrical cable.
9.) Add coolant.
Add coolant (deionized water) to the fill reservoir. The coolant will drain out of the fill reservoir and
into the main reservoir. The system uses approximately 2.5 gallons of coolant. Most of the coolant
can be added at this time - until the fill reservoir level stays up. The system coolant level will be
"topped off" after the system is turned on (in a later step).
9.) Initial power application.
CAUTION: Once the circuit breaker is turned on lethal voltages are present throughout the system.
With the side covers still removed, turn on the electrical service and turn on the circuit breaker on the
VersaPulse Select. Wait a few minutes, observing for any indication of failure of mains or turn-on
components.
10.) Initial turn on.
CAUTION:
• The system will fire during the turn-on sequence if SW3 (Autocal) on the CPU PCB is up
and the BRH plug is installed. Only those persons required should be present during this
portion of the installation
• The cooling fan blades are not covered. The fan is located on top of the heat exchanger. It
operates whenever the system is turned on. Keep tools, system parts and body parts clear of
the fan blades.
Turn the keyswitch to the START position, then release it to the ON position. The system will go
through its start up sequence. Observe for normal start up, and for any indication of leaks in the
cooling system.
