Page 7: Introduction
Space Savings The Liebert InteleCool2 does not use any of the valuable floor space inside the secure space. Instead, it is mounted on the outside wall. No additional space is required outside or on a roof. Easy to Install The Liebert InteleCool2 is assembled, wired, piped, charged with refrigerant and factory tested as a system to ensure trouble-free installation and startup. -
Page 8: Optional Features
Compressor Crankcase Heater An optional compressor crankcase heater is available for use with the scroll compressor, but it is not required because the refrigerant charge of the Liebert InteleCool2 unit with scroll compressor is less than the compressor critical charge. -
Page 9: Refrigeration System Options
Refrigeration System Options Low-Pressure Switch and Low-Pressure Bypass Timer Low-Pressure Switch: Used to protect the Liebert InteleCool2 if the evaporator blower fails, the air filter becomes clogged, the refrigeration circuit malfunctions or if there is loss of refrigerant. The low-pressure switch is activated when the suction pressure drops below its cutout setting. When activated, the low-pressure switch inhibits operation of the compressor and condenser fan. -
Page 10: Installation
2.1.2 Location Considerations The Liebert InteleCool2 unit is field-mounted on an outside wall. Additional framing in the wall may be required to ensure adequate structural support. The outdoor area near the condenser supply and discharge must also be considered. To ensure adequate air supply, the unit should be mounted in a clean area, away from loose dirt and foreign matter that may clog the condenser coil. -
Page 11: Piping Connections
(111) Piping Connections The Liebert InteleCool2 is a self-contained, packaged unit. All refrigerant piping connections are made at the factory, so no external condenser is required. The evaporator coil condensate drain is factory-supplied and drains outdoors through the unit base pan. The condensate drain tubing should be checked to be certain that it is placed through the hole provided in the base pan. -
Page 12: Electrical Connections
Make sure that the voltage supplied agrees with the voltage specified on the unit nameplate. The Liebert InteleCool2 comes standard with a factory-installed circuit breaker, accessible through an external access panel. An external, wall-mounted power disconnect switch (field-supplied) may be required for local codes. -
Page 13: Control Connections
If you have questions, contact the thermostat manufacturer. Liebert Dual Unit Control The Liebert Dual Unit Control is designed to control two Liebert InteleCool2 units in a “lead/lag” fashion. The control contains an electronic timer for switching the operating sequence of two units on a one-, two-, four-, or eight-day basis. -

Page 17: Operation
Compressorized cooling is provided by a high-efficiency system consisting of a compressor, thermostatic expansion valve, evaporator, and condenser coil. The Liebert InteleCool2 uses R-407C refrigerant in a conventional vapor-compression refrigeration cycle. Heat is removed from the air in the space by blowing the air across the evaporator coil. As heat is transferred to the refrigerant in the evaporator, the refrigerant boils and turns to a warm vapor. -
Page 18: Economizer Cooling-Optional
Heating - Optional On units supplied with optional resistance heating, a call for heating closes the heat relay and energizes the evaporator fan and resistive elements. ® ® Liebert InteleCool... -
Page 19: Unit Controls
The high-pressure switch is mounted in the liquid line. Electrically, it is connected in series with the compressor start circuit, which will shut down the compressor and condenser fan if the liquid pressure exceeds 400 PSIG (2758 kPa). This protects the Liebert InteleCool2 in the event of condenser motor failure or condenser coil blockage. -
Page 20: Anti-Short Cycle Timer - Standard
Includes a low-pressure switch, low-pressure bypass timer (described above) and fan cycle control. Fan Cycle Control—Condenser Fan Cycling Control; allows the Liebert InteleCool2 unit to provide cooling to the space when the outdoor ambient temperature is lower than 50°F (10°C) and down to -20°F (-28.9°C). -
Page 21: Aintenance
Each month, the components of the refrigeration system should be inspected for proper function and signs of wear. Since, in most cases, evidence of malfunction is present prior to component failure, periodic inspections can be a major factor in the prevention of most system failures. ® ® Liebert InteleCool... -
Page 22: Refrigerant Lines
The correct superheat setting is between 10° and 20°F (5.5° and 11.1°C) under normal load conditions and “steady-state” operation. Some models of the Liebert InteleCool2 will be supplied with a non-adjustable expansion valve, so no adjustments are possible. - Page 23 Alco Dri-Kleener. Whichever kit is used, follow the manufacturer’s procedure. CAUTION Risk of caustic material. Can cause personal injury. Avoid skin contact with the refrigerant and oils. Severe burns will result. Use long rubber gloves when handling contaminated parts. ® ® Liebert InteleCool...
