Additional Information For Initial Start-up
Standard Range units CCH
Units are designed to start-up in an ambient of 50°F (10°C),
with entering air at 50°F (10°C), with entering water at 70°F
(21°C),withbothairandwaterowratesusedintheISO
13256-1 rating test, for initial start-up in winter.
Note: This is not a normal or continuous operating
condition. It is assumed that such a start-up is for
the purpose of bringing the building space up to
occupancy temperature.
Geothermal Range units CCW
Geothermal heat pump units are designed to start-up in an
ambient of 40°F (5°C), with entering air at 40°F (5°C), with
enteringwaterat25°F(-4°C),withbothairandwateratow
rates used in the ISO 13256-1 rating test, for initial start-up
in winter.
Note: This is not a normal or continuous operating
condition. It is assumed that such a start-up is for
the purpose of bringing the building space up to
occupancy temperature.
Operating Voltages

Note: Voltages listed are to show voltage range. However,
units operating with overvoltage and undervoltage for
extended periods of time will experience premature
component failure. Three phase system unbalance
should not exceed 2%.
