Make sure all blowers fans and the scroll compressor are rotating in the correct direction Check the current draw on all line voltage components and compare with unit nameplate 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 start up 10 Operation 5 0 OPERATION 5 1 Compressorized Cooling Compressorized cooling is provided by a high efficiency system consisting of a compressor thermo static 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 The refrigerant vapor enters the compressor and is compressed resulting in high pressure and tem perature After entering the condenser the hot vapor is condensed to a liquid by the air blown across the condenser coil Liquid refrigerant then passes through the thermal expansion valve and into the evaporator The expansion reduces the pressure and temperature to complete the cycle Figure 4 Refrigeration system Therma

Mechanical cooling and Economizer operation do not operate simultaneously Fresh Air Damper Allows outside air to be brought in to meet indoor air requirements Air is drawn in through the evap orator filter The amount of air to be introduced to the space is field selectable Panel Colors Optional color choices for the steel panels are almond light tan the color option for the original Liebert InteleCool desert brown or bright white Lockout Relay The lockout relay latches the detection of a high pressure condition in the refrigeration circuit and prohibits operation of the compressor until the abnormal pressure conditions are acknowledged The lockout relay is reset by cycling the unit main power or by changing the setpoint on the thermostat to temporarily eliminate a call for cooling A normally open set of contacts is provided to terminals 2 and 3 of the customer terminal strip for monitoring the status of the lock out relay when this option is sup plied without the Common Alarm option Common Alarm The common alarm provides the necessary components to detect high pressure low pressure high temperature or loss of indoor airflow and to provide a customer signal via a contact closure To detect low pressure the optional low pressure switch with bypass T pack1 or T pack2 must also be selected Soft Start Provides a PTC resistor to assist the start of the compressor motor in low voltage operation Available only on single ph

25. the lookout for abnormal operation can be a major factor in reducing maintenance costs It is easier and far less costly to take the steps necessary to ensure proper system operation than it is to allow a compressor to fail and require replacement When troubleshooting a compressor check all electrical components for proper operation including all fuses and circuit breakers and pressure switch operation If a compressor failure has occurred determine whether it is an electrical or mechanical failure 16 Maintenance 6 6 1 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 If a burnout does occur correct the problem that caused the burnout and clean the system thoroughly using the proper procedure It is important to note that successive burn outs of the same system are usually caused by improper cleaning NOTICE Risk of contaminated system Can cause equipment damage Damage to a replacement compressor caused by improper system cleaning constitutes abuse under the terms of the warranty and the WARRANTY WILL BE VOIDED There are two kits that can be used with a complete compressor burnout Sporlan Sys
