GENERAL GENERAL STATEMENT This unit is from the PT series that was designed & built for the optimum performance. However, it is required that you become well acquainted with good practices for the proper installation/operation/and maintenance procedures in order to ensure a safe trouble free operation, year after year. Please read through the whole manual contents before you attempt to install/operate/ and maintain the unit.
INSTALLATION INSTRUCTIONS GENERAL These units are shipped completely assembled, charged, and wired. They do not require any field installation of refrigerant tubing. Units require external power, thermostat wiring, condensate drain piping and ducting as applicable. Size of unit for an installation should be based on a heat gain calculation made according to applicable standards.
SERVICE CLEARANCE MODELS: PT036 - PT120 MODELS: PT180 - PT360 D D E C C A A B B NOTE: Only two condenser fans for models PT180 - PT240. NOTE: All dimensions are in cm.
CONDENSATE DRAIN CONNECTION • • • Use standard PVC pipe with NPT connection for the condensate drain. Provide a 'P' trap immediately at the condensate drain connection. Piping has to be sloped away from the unit. Remember to remove the drain hole plug before operating the unit. Avoid bends & elbows. DUCT CONNECTION The units can be connected to the ducting in horizontal configuration. Connect ducting using flexible duct connection.

Performex-1TM CONTROLLER : OPERATION & FUNCTIONS The COOLINE Packaged units are provided with technologically advanced new PerformexTM Controller Microprocessor Based Electronic Control Board, incorporating the following benefits and features: - COMPLETE UNIT CONTROL: Provides complete unit control for heating and cooling application whether single stage or two stage utilizing the input from sensor that measure temperatures during unit operation.
7. LEAD/LAG OPERATION: Whenever a compressor needs to be on, the controller will turn on the compressor with the shorter accumulated run time provided its 3 minutes minimum off time has lapsed. Otherwise the other compressor will on first. Similarly, the compressor with the longer accumulated run time will be the first one to be cut off. This is to load the compressors evenly over long run period. Balance loading is enabled when compressor #1 lead option is disabled. 8.
MAINTENANCE INSTRUCTIONS AIRFLOW ADJUSTMENT (Applicable for PT075 - PT360 only) The airflow could be adjusted by adjusting pulleys of blower motor or belt tension with proper mounting and alignment of the pulleys: • Refer to fan performance tables in the catalog for selecting applicable airflow, RPM and brake horse power at specified static pressure. • • • Select the appropriate drive as per motor and blower characteristic in the catalog. • • Tighten the set screw and then install the belts.
