o Chilled water barrel heaters for freeze protection o Chiller provided with hydronic isolation and drain valves.

o Main power wiring will include single (1) Cam Lok electrical connections and associated wiring o Chiller shall be furnished with a 2” x 4” label with white backing and black lettering stating “NOTE: 480-volt power should be applied a minimum of 1 hour before starting chiller. Compressor oil heaters utilize 480 volt power.”

� Provide and install pump rated @ 300 GPM @ 100 foot/head. Pump will be mounted to the chiller skid. The close coupled pump will be integrated into the interconnecting piping and hydronic components. Installation to include a pump starter, overload, control switch and breaker.

� Internal chiller piping package to include:

o Integrated bypass to provide operation of local or remote pumps o Chiller to be provided with isolation/balancing valves, bypass valve for remote pump operation, in-line strainer with blow down valve, and low level drain valve.

o Entering and leaving fluid temperature ports and thermometers o Entering and leaving pressure ports and gauges o Drain valves at chiller barrel, pump housing and at the piping manifold lowest point.

o Chiller will be provided with an additional differential pressure safety switch. This pressure switch is independent of the factory installed safety switch.

o Provide two (2) additional ¼” access ports for field pressure/temperature testing.

o Perform hydrostatic pressure testing to 125 PSIG of the entire pump, piping and component assembly to verify no leaks are present.

o 60’ of quick connect hoses and 60’ of return hoses.
