INSTALLATION INSTRUCTIONS FOR LIGHT COMMERCIAL SELF-CONTAINED PACKAGED HEATING & COOLING UNIT 3 TON - 6 TON CPC/CPH SERIES RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION. ATTENTION INSTALLING PERSONNEL Prior to installation, thoroughly familiarize yourself with this Installation Manual. Observe all safety warnings. During installation or repair, caution is to be observed. It is your responsibility to install the product safely and to educate the customer on its safe use.
Index REPLACEMENT PARTS Replacement Parts ........................................................ 2 ORDERING PARTS Safety Instructions ........................................................ 2 When reporting shortages or damages, or ordering repair parts, give the complete unit model and serial numbers as stamped on the unit’s nameplate.

NATIONAL CODES WARNING This product is designed and manufactured to permit installation in accordance with National Codes. It is the installer’s responsibility to install the product in accordance with National Codes and/or prevailing local codes and regulations. THIS UNIT MUST NOT BE USED AS A “CONSTRUCTION HEATER” DURING THE FINISHING PHASES OF CONSTRUCTION ON A NEW STRUCTURE.
NOTE: When inspecting the unit for transportation damage, remove all packaging materials. Recycle or dispose of the packaging material according to local codes. • Allow minimum clearances from the enclosure for fire PRE-INSTALLATION CHECKS • Carefully read all instructions for the installation prior to installing unit. Ensure each step or procedure is understood and any special considerations are taken into account before starting installation.
Full perimeter roof curbs are available from the factory and are shipped unassembled. Field assembly, squaring, leveling and mounting on the roof structure are the responsibility of the installing contractor. All required hardware necessary for the assembly of the sheet metal curb is included in the curb accessory. Adequate clearance around the unit should be kept for safety, service, maintenance, and proper unit operation.
PROTRUSION RIGGING DETAILS Inspect curb to ensure that none of the utility services (electric) routed through the curb protrude above the curb. WARNING TO PREVENT PROPERTY DAMAGE, THE UNIT SHOULD REMAIN IN AN UPRIGHT POSITION DURING ALL RIGGING AND MOVING OPERATIONS. TO FACILITATE CAUTION LIFTING AND MOVING WHEN A CRANE IS USED, PLACE THE UNIT IN AN ADEQUATE CABLE SLING. IF PROTRUSIONS EXIST, DO NO ATTEMPT TO SET UNIT ON CURB.
Lower unit carefully onto roof mounting curb. While rigging unit, center of gravity will cause condenser end to be lower than supply air end.
All line voltage connections must be made through weatherproof fittings. All exterior power supply and ground wiring must be in approved weatherproof conduit. CAUTION TO PREVENT SEVERE DAMAGE TO THE BOTTOM OF THE UNIT, DO NOT FORK LIFT UNIT AFTER WOOD STRUTS HAVE BEEN REMOVED .
MAIN POWER LOW VOLTAGE BLOCK RETURN LOW VOLTAGE ENTRANCE SUPPLY 3.5 DIA. POWER THRU THE CURB 41/2” POWER THRU THE CURB CONTROL BOX 47 1/2” WARNING FAILURE OF UNIT DUE TO OPERATION ON IMPROPER LINE VOLTAGE OR WITH EXCESSIVE PHASE UNBALANCE CONSTITUTES PRODUCT ABUSE AND WILL VOID YOUR WARRANTY AND MAY CAUSE SEVERE DAMAGE TO THE UNIT ELECTRICAL COMPONENTS. LOW VOLTAGE CONTROL WIRING 1. A 24V thermostat must be installed for unit operation. It may be purchased with the unit or field -supplied.
CIRCULATING AIR AND FILTERS STARTUP, ADJUSTMENTS, AND CHECKS DUCTWORK WARNING The supply duct from the unit through a wall may be installed without clearance. However, minimum unit clearances must be maintained (see “Clearances” section). The supply duct should be provided with an access panel large enough to inspect the air chamber downstream of the heat exchanger. A cover should be tightly attached to prevent air leaks.
TOOLS REQUIRED System Voltage - That nominal voltage value assigned to a circuit or system for the purpose of designating its voltage class.
ing and clamps. The entire refrigeration system has been factory charged and tested, making it unnecessary to field charge. Factory charges are shown on the unit nameplate. Install service manifold hoses. Gauges should read saturation pressure corresponding to ambient temperature. Charge should be checked to obtain 12° to 15° of sub-cooling per system (i.e. compressor circuits). START-UP PROCEDURE AND CHECKLIST Begin with power turned off at all disconnects. 1.
REFRIGERATION PERFORMANCE CHECK 11. Slowly raise the heating temperature setting. When the heating first stage makes contact, stop raising the temperature setting.. The compressor, blower and fan should now be running with the reversing valve in the de-energized (heating) position. After giving the unit time to settle out, make sure the unit is supplying heated air. 12. If the outdoor ambient is above 80°F, the unit may trip on its high pressure cut out when on heating. The compressor should stop.
DEFROST CONTROL C O O LIN G S E RV IC E P O RT R E V E RS IN G V A LV E During operation the power to the circuit board is controlled by a temperature sensor, which is clamped to a feeder tube entering the outdoor coil. Defrost timing periods of 30,60 and 90 minutes may be selected by setting the circuit board jumper to 30, 60 and 90 respectively. Accumulation of time for the timing period selected starts when the sensor closes (approximately 31° F), and when the wall thermostat calls for heat.
DRIVE ADJUSTMENTS MOTOR SHEAVE ADJUSTMENTS CAUTION SHEET METAL PARTS, SCREWS, CLIPS AND SIMILAR ITEMS INHERENTLY HAVE SHARP EDGES, AND IT IS NECESSARY THAT THE INSTALLER AND SERVICE PERSONNEL EXERCISE CAUTION. VL, VM, & 2VP VARIABLE PITCH KEY TYPE MOTOR SHEAVES The driving and driven motor sheaves should be in alignment with each other and the shafts parallel.
LUBRICATION UNDERCHARGE The fan shaft bearings, the 1 to 2 HP supply fan motors the condenser fan motors and compressors are permanently lubricated. An undercharged heat pump on the heating cycle will cause low discharge pressure resulting in low suction pressure and frost accumulation on the outdoor coil. FUNCTIONAL PARTS POOR “TERMINATING” SENSOR CONTACT Refer to the unit Parts Catalog for a list of functional parts. Parts are available from your distributor.
