WARNING!
When the disconnect switch is closed, high
voltage is present in some areas of the electrical panel.
Exercise caution when working with energized equipment.
CAUTION!
Verify that ALL water control valves are open and
allow water flow prior to engaging the compressor. Freezing
of the coax or water lines can permanently damage the heat
pump.
⚠
WARNING!
⚠
⚠
CAUTION!
⚠
Operating Pressure/Temperature tables include the
following notes:
• Airflow is at nominal (rated) conditions;
• Entering air is based upon 70°F [21°C] DB in heating
and 80/67°F [27/19°C] in cooling;
• Subcooling is based upon head pressure at compressor
service port;
• Cooling air and water values can vary greatly with
changes in humidity level.
CAUTION!
Many units are installed with a factory or field
supplied manual or electric shut-off valve. DAMAGE WILL
OCCUR if shut-off valve is closed during unit operation. A
high pressure switch must be installed on the heat pump side
of any field provided shut-off valves and connected to the
heat pump controls in series with the built-in refrigerant circuit
high pressure switch to disable compressor operation if water
pressure exceeds pressure switch setting. The field installed
high pressure switch shall have a cut-out pressure of 300
psig and a cut-in pressure of 250 psig.
