14. Test the unit functions before turning the Mini-dap4 or dap4 controller on by performing the following
procedure.
a. Temporarily disconnect the J1 connector off the dap4 control module, turn the unit power ON.

NOTICE. The pressure relief valve line must be vented to the atmosphere per
latest of ASHRAE Standard 15 and or any local Building, Fire, or Mechanical
Codes.
NOTICE. As a minimum, the installer should wear thermal protective gloves and
face-shield/goggles when working with refrigerant. Application of excessive
heat to any component will cause extreme pressure and may result in a rupture.
Exposure of refrigerant to an open flame or a very hot surface will cause a
chemical reaction that will form a highly poisonous and corrosive gas commonly
referred to as PHOSGENE. In its natural state, refrigerant is a colorless, odorless
vapor. It is heavier than air and will disperse rapidly in a well-ventilated area. In
an unventilated area, it presents a danger.
NOTICE. Before carrying out the pressure test, precautions shall be taken to
evacuate all personnel from the area of risk and post notices advising that the
system or equipment is under pressure.
