NOTES:

Steps 3-9 should be conducted with the hot water generator disconnected.

Use 500 for pure water, 485 for methanol or Environol™. (This constant is derived by multiplying the weight of one gallon of water (8.34) times the minutes
in one hour (60) times the specific heat of the fluid. Water has a specific heat of 1.0.

If there is only one source of power for the compressor and blower, amp draw can be measured at the source wiring connection.

Liquid line is between the coax and the expansion device in the cooling mode; between the air coil and the expansion device in the heating mode.
