Figure 4- Typical Piping Water/Glycol Cooled System

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 equipment problems.

2.5.3Pump 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.

2.6Utility Connections

2.6.1Main 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/
