A list of the contractor responsibilites typically associated
with the installation process is provided in Table 2.

• Locate and maintain the loose parts. Loose parts are
located in the control panel.
Measurement conditions:
• Install the unit on a foundation with flat support surfaces,

level within 5 mm and of sufficient strength to support
long) fixed to its discharge opening.

• Supply and install flow switches or equivalent devices
in both the chilled water and condenser water piping.
Interlock each switch with the proper pump starter and
Tracer UC800, to ensure that the unit can only operate
when water flow is established.
• Supply and install taps for thermometers and pressure
gauges in the water piping, adjacent to the inlet and outlet
connections of both the evaporator and the condenser.
• Where specified, supply and install strainers ahead of all
pumps and automatic modulating valves.
• Supply and install refrigerant pressure relief piping from
the pressure relief to the atmosphere.
• Start the unit under supervision of a qualified service
technician.
