Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) GENERAL YORK Saber units are single package air conditioners equipped with optional factory installed electric heaters and designed for outdoor installation on a rooftop or steel structure. The units are completely assembled on a rigid base frame. All piping, refrigerant charge, and electrical wiring is factory installed and tested. The units require electric power, duct connections and drain piping connections at the point of installation.
Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) PRODUCT NOMENCLATURE INSTALLATION LIMITATIONS Read these instructions before continuing this appliance installation. This is an outdoor combination heating and cooling unit. The installer must assure that these instructions are made available to the consumer and with instructions to retain them for future reference. These units must be installed in accordance with the applicable national and local safety codes.
Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) LOCATION Use the following guidelines to select a suitable location for these units : 1. 2. 3. 4. 5. 6. Unit are designed for outdoor installation only. Condenser coils must have an unlimited supply of air. Where a choice of location is possible, position the unit on either north or east side of building. For ground level installation, use a level concrete slab with a minimum thickness of 4 inches.
Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) CONDENSATE DRAIN Plumbing must conform to local codes. Use a sealing compound on male pipe threads. Install a condensate drain line from the one inch FPT female connection on the unit to an open drain. NOTE : The condensate drain operates in a negative pressure in the cabinet. The condensate drain line MUST be trapped to provide proper drainage. See Figure 4.
Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) COMPRESSORS Units are shipped with factory adjusted compressor mountings and ready for operation. If any of the wire supplied with the unit must be replaced, replacement wire must be of the type shown on the wiring diagram and the same minimum gauge as the replaced wire. Electrical line must be sized properly to carry the load. Use copper conductors only.
Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) FIGURE 7 : Typical Field Wiring Schematic PHASING YORK® Saber units are properly phased at the factory. Check for proper compressor rotation. If the blower or compressors rotate in the wrong direction at start up, the electrical connection to the unit is misphased. Change the incoming line connection phasing to obtain proper rotation. (Scroll compressors operate in only one direction. If the scroll is misphased).

Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) CHECKING SUPPLY AIR CFM The RPM of the supply air blower will depend on the required CFM, the unit accessories or options and the static resistances of both the supply and the return air duct systems. With this information, the RPM for the supply air blower and the motor pulley adjustment (turns open) can be determined from the Fan Performance Data Tables.
Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) OPERATION AND USE OF THE UNIT IN CONFORMANCE WITH GENERAL STANDARDS AND PROVISIONS 3. Warnings against coming into contact with electrical parts. YORK® DMS Saber Roof Top Packaged Air Conditioners are designed for and are able to cool, heat, filter air and operate in the fan mode.

Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) RECOMMENDED SAFETY PRACTICES This publication explains the proper use and installation of equipment in order to warn operating and maintenance personnel of the commonly recognized dangers associated with this equipment. In addition to following the manufacturer’s installation instructions, care must be taken to ensure compliance with federal, state and local rules, regulations, codes and standards.
Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) OPERATION SOUND POWER RATINGS A sound power level is a measure of the total noise radiated by the machine in all directions. It is a property of the machine and is essentially independent of the measuring environment. Sound power levels are useful to equipment manufacturers, buyers, installers, and users for: t t t t Calculating the sound pressure level from a machine at a given distance in a given environment.
Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) Y2. If the compressors have satisfied their minimum run times, the compressors and condenser fansare de-energized. Otherwise, the unit operates each cooling system until the minimum run times for the compressors have been completed. Upon the final compressor de-energizing, the blower is stopped following the elapse of the fan off delay for cooling.
Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) b. motor. If the second stage of heat is required, second heater contactor will be energized. After completing the specified fan on delay for heating, the UCB will energize the blower motor. The thermostat will cycle the electric heat to satisfy the heating requirements of the conditioned space.
Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) * On calls for cooling, if the compressors are operating but the supply air blower motor does not energize after a short delay (the room thermostat fan switch is in the “AUTO” position). Turn the thermostat fan switch to the ON position. If the supply air blower motor does not energize, go to Step 3. 2.
Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) 3. 4. 5. 6. 7. 8. If compressor contactor 2 is not pulled in, check for 24 volts at the compressor contactor coil. If 24 volts is present and compressor contactor is not pulled in, replace the contactor. Failing the above, if voltage is supplied at compressor contactor 2, and it is pulled in, and the compressor still does not operate, replace the compressor.
Installation, Operation & Maintenance Manual (IOPCKKS60220510B1) UNIT FLASH CODES Various flash codes are utilized by the unit control board (UCB) to aid in troubleshooting. Flash codes are distinguished by the short on and off cycle used (approximately 200 ms on and 200 ms off). To show normal operation, the control board flashes a 1 second on, 1 second off heartbeat during normal operation. This is to verify that the UCB is functioning correctly. Do not confuse this with an error flash code.
