WARNING
Glycol is hazardous. Consult the manufacturer's
MSDS for detailed safety information.
CAUTION
When installing and filling the water/glycol loop all
air must be bled from the piping system and the
piping system must be cleaned prior to operating
the system. Failure to do so will result in equip-
ment problems.
2.5.3 Pump Package
2.5.3.1 Suction Side Piping
Install a concentric reducer at the pump suction
opening and make all suction piping at least one-(1)
size larger than the diameter of the suction inlet. If
necessary, install a suction strainer with a net area 2-3
times larger than the suction piping. The piping leaving
the drycooler should enter the pump suction port.
Install a ball valve in the suction line for maintenance
purposes.
2.5.3.2 Discharge Side Piping
Install a concentric reducer at the pump discharge
opening and make all discharge piping at least one-(1)
size larger than the diameter of the discharge outlet.
Install a check valve in the discharge line to prevent
back flow that may damage the pump on shut down.
Install a ball valve in the discharge line for maintenance
purposes.
2.6 Utility Connections
2.6.1 Main Power
The CyberChiller product offering is available in 208-
230 VAC single-phase or 460 VAC three-phase
configurations. It is imperative that the unit nameplate
be examined to determine the operating voltage,
frequency and phase of the system. (See Figure 5.)
The nameplate also provides the full load amps (FLA),
the current that the unit will draw under full design
load, the minimum circuit ampacity (MCA) for wire
sizing, and the maximum fuse or HACR (Heating, Air
Conditioning, Refrigeration) breaker size (MAX FUSE/
