Installation
Water Temperature Requirements
Do not allow the entering water
temperature to go below 54 F (12.2 C) on
units with constant water flow (basic
piping). This will cause the compressors
to shut down and the mechanical cooling
function will lockout. However, the
economizer (if enabled) will continue to
function. The compressors will reset
when the entering water temperature
reaches 58 F (15C).
Units with variable water flow
(intremediate piping) have a modulating
condensing pressure control valve that
allows compressor operation down to
entering water temperatures of 35 F (2
C).
For more information on constant and
variable water flow, see the Owner’s
section of this manual.
Note: Units with a waterside economizer
can be set from the human interface panel
for variable or constant water flow.
