Page 7: Introduction
Introduction NTRODUCTION General The Liebert InteleCool2 Environmental Control System was designed for convenience and dependability in unmanned and remote locations typical of the telecommunications industry. Ease of installation, operation and service coupled with the use of high quality, high reliability components make the Liebert InteleCool2 ideally suited for maintaining an environment for sensitive electronic equipment. -
Page 8: Optional Features
Introduction Optional Features 4 or 5 Ton Unit With 3 Ton Openings The 4- or 5-ton units with 3 ton supply and return openings are designed to replace 3 ton wall mounted air conditioners using existing wall openings. The economizer/fresh air option is not available. -
Page 9: Refrigeration System Options
Introduction 1.3.1 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. -
Page 10: Installation
Upon delivery of the unit, inspect all items for visible damage. Concealed damage may be discovered later during installation. Report any damage to the shipper immediately and file a damage claim. Also, forward a copy of the damage claim to your Emerson supplier. Unit Installation The Liebert InteleCool2 unit is installed against, and through, an outside wall. -

Page 13: Control Connections
Installation 2.5.2 Control Connections Control wiring will be required for the remote control device. This remote device may be a factory- or field-supplied wall thermostat or similar device. Connections to the unit are made using customary HVAC low volt wiring terminals R, G, W, and Y. For detailed locations of the low volt wiring terminals, please refer to the Figure 10 - Electric panels. -
Page 14: Outside Air Damper-Optional
Installation Outside Air Damper—Optional Units supplied with fixed (non-modulating) outdoor air damper can be adjusted as follows: 1. Remove the screws from the middle panel and remove panel. 2. Loosen the damper plate screws on the backside of the middle panel. 3. -
Page 15: Checklist For Complete Installation
Checklist for Complete Installation HECKLIST FOR OMPLETE NSTALLATION ___ 1. Proper clearance for service access has been maintained. ___ 2. Equipment is level and mounting fasteners are tight. ___ 3. Ducting completed, if required. ___ 4. Line voltage to power wiring matches equipment nameplate. ___ 5. -
Page 16: Startup Procedure
8. Check adjustment of the optional outside air damper for the desired balance between the flow of room air and outdoor air. Use a gauge or non-polluting airflow indicator. NOTE If the unit is supplied with crankcase heaters, Emerson recommends that the high voltage be applied between four and six hours before startup. -
Page 17: Operation
Operation PERATION Compressorized Cooling 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
Operation Economizer Cooling—Optional The Economizer mode uses outside air to cool the room when the outside air temperature is cool enough to allow for economical cooling. Components include the damper, spring return direct drive actuator, enthalpy sensor and actuator control board with an integral mixed air sensor. Economizer operation is enabled when the outside conditions meet required temperature and humidity as set on the enthalpy sensor. -
Page 19: Unit Controls
Operation Unit Controls 5.4.1 Remote Control Interface Control connections to the Liebert InteleCool2 unit use customary HVAC terminal designations R, G, W & Y. Contact closures between the 24 VAC (R) and different control connections supply control voltage to the electric panel components responsible for the desired function. Operating modes are controlled by contact closures as follows: Table 2 Operating modes/contact closures... -
Page 20: Anti-Short Cycle Timer - Standard
Operation T-pack1 package 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
Maintenance AINTENANCE WARNING Risk of electric shock. Can cause injury and death. Disconnect all local and remote electric power supplies before working within. Potentially lethal voltages exist within this equipment during operation. Observe all cautions and warnings in this manual. Only qualified service and maintenance personnel should work with this equipment. -
Page 22: Refrigerant Lines
Maintenance 6.5.1 Refrigerant Lines Check all refrigerant lines and capillaries for vibration isolation, and support as necessary. Visually inspect all refrigerant lines for leaks. 6.5.2 Discharge Pressure Discharge pressure can be increased or decreased by load conditions or condenser efficiency. The high-pressure switch will shut the compressor/contactor at its cut-out setting of 400 PSIG (2758 kPa). - Page 23 Maintenance Mechanical Failure A mechanical compressor failure will not be indicated by a burned odor. The motor will attempt to run. If you have determined that a mechanical failure has occurred, the compressor must be replaced. Electrical Failure An electrical failure will be indicated by a distinct pungent odor. If a severe burnout has occurred, the oil will be black and acidic.

Page 24: Compressor Replacement
6.6.1 Compressor Replacement Replacement compressors are available from your Emerson supplier. They will be shipped in a reusable crate to the job site as required by the service contractor. Upon shipping a replacement compressor, the service contractor will be billed in full for the compressor until the failed compressor has been returned to the factory. -
