Piping Considerations—Water/Glycol Models Only

5.0PIPING CONSIDERATIONS—WATER/GLYCOL MODELS ONLY

The XDF’s supply and return fittings are on the upper portion of the rear of the unit (see Figure 6). The 1-1/8" diameter pipes have one-inch female NPT fittings. The pipes are capped at the factory. Pip- ing connections to the XDF should be done by qualified personnel. All work must be done in compli- ance with all national and local regulations.

5.1General

Equipment damage and personal injury can result from improper piping installation, leak checking, fluid chemistry and fluid maintenance.

• Follow local piping codes, safety codes and Liebert unit installation and maintenance instruc- tions.

• Qualified personnel must install and inspect system piping.

• Contact a local water consultant regarding water quality, corrosion protection and freeze protec- tion requirements.

! CAUTION

Risk of dirt and debris contamination. May cause condenser clogging.

Do not install the XDF on an open-loop water supply system. Debris carried by the fluid will clog the XDF’s brazed plate condenser.

! CAUTION

Risk of piping stress. Can cause leaks and equipment damage.

To help prevent piping failures, supply and return lines must be supported so that their weight does not bear on the XDF’s piping, on the drycooler or on the pumps.

5.2Closed Loop Water System

Where water will be used as a coolant medium, Liebert recommends use of a closed-loop water system with a cooling tower or similar heat dissipation method. For flow rates for the XDF water/glycol unit, see Table 2.

Table 2	Water supply flow rates

Entering Water Temp.		Saturated Cond. Temp.	Flow Rate	Pressure Drop
	EWT	SCT	GPM (l/s)	ft (kPa)
65°F (18°C)		105°F (41°C)	15.0 (.95)	4.6 (13.8)

75°F (24°C)		105°F (41°C)	15.0 (.95)	4.6 (13.8)

85°F (29°C)		110°F (43°C)	15.0 (.95)	4.6 (13.8)

Table assumes 95°F ambient, 77°F discharge air, 10°F temperature rise on the heat transfer media.
