Be sure you understand and follow the procedures and safety precautions contained in the machine instructions as well as those listed in this guide. DO NOT USE OXYGEN or air to purge lines, leak test, or pressurize a machine. Use nitrogen. NEVER EXCEED specified test pressures. For the 16DF machine, the maximum pressure is 12 psig (83 kPa). For the chilled/hot water and condensing water piping, the maximum pressure is stamped on the machine. WEAR goggles and suitable protective clothing when han

NOTES: 1. Main power must be supplied from a field-supplied fused electrical service with a (factory-or field-installed) disconnect located in sight from the unit. 2. Control circuit power must be supplied from a separate source through a field-supplied disconnect. The control circuit accessory transformer may be applied to power from the main unit power supply. 3. Maximum incoming wire size for each terminal block is 500 kcmil. 4. Maximum allowable phase imbalance is: voltage, 2%; amps, 5%. 5.
