At this point if all Pre-Startup and Startup procedures and checks have been
completed, it is safe to turn the heat pump “on” at the control interface.
Doublecheck that all configuration options on the control interface are set as
required for this project.
Typically, a demand for heating should start, as the tanks should be cold. If not,
dump hot water until a demand is initiated. If BMS control is involved, ensure
that BMS has not “disabled” the heat pump.
Wait a total of 20 minutes before taking the following operational readings
after a heat demand initiates. This includes several minutes of startup delay
before compressor operation begins, and several more minutes of continuous
operation. Pressures and readings should be somewhat stable before readings
are taken.
Record the following readings from the control interface:
Condenser flow rate:_________ GPM
Condenser EWT:_________ Deg. F.
Superheat:_________ Deg. F.
Suction Temp:_________ Deg. F.
Ambient Temperature:_________ Deg. F.
Condenser LWT:_________ Deg. F.
Liquid Line Temp:_________ Deg. F.
Discharge Temp:_________ Deg. F.
