WARNING
InteleCool and InteleCool2 units contain potentially lethal voltage.
Shut off power before performing any service work.
During service, the P2 jumper should be placed on the pins that identify the unit NOT being
serviced. Refer to Table 2 for required jumper pin connections. The P2 setting will override
the lead unit setting until the jumper is returned to the proper number-of-days location.
