TRUCLIMATE 300 WATER-COOLED CHILLER WITH HYBREX TECHNOLOGY INSTALLATION MANUAL -
Formerly the WC Hybrex Chiller
Chiller Installation cont.
Temperature Header Installation
The chiller plant requires global temperature read-
ing to properly control the staging of the chillers. The
global temperature sensors are placed in a temperature
header in the inlet and outlet of each loop between the
chiller plant and the building. The temperature header is
provided as a separate line item and is a fi eld installed
item. The temperature sensors and optional differential
sensors need to be fi eld wired to the primary HydroLink2
controller.
The default confi guration of the temperature header
consists of factory installed temperature sensor and
P/T port. Optional differential pressure sensors are fi eld
installed in place of the P/T port.
Installation Recommendations:
1.
Do not over torque the bolts of the groove pipe fi t-
tings. Recommended tightening torque: 73 ft-lb.
2. Always
rotate
the temp header so full access is pro-
vided to the sensors and P/T port.
3.
Insulate Header with min CCF insulation with mini-
mum thickness of 0.75in.
