NOTES:
1
Steps 3-9 should be conducted with the hot water generator disconnected.
2
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.
3
If there is only one source of power for the compressor and blower, amp draw can be measured at the source wiring connection.
4
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.
