Be sure to use the supplied conduit bushing to prevent damage to the cord by the conduit. The cord should pass through the Locknut, Spacer, Chassis Junction Box, Conduit Connector, Bushing, then the Conduit Sleeve.
Remote Thermostat and Low Voltage Control Connections Remote Thermostat All Friedrich PD model PTAC units are factory by either the chassis mounted Smart Center or a 24V remote wall mounted thermostat. The thermostat may be auto or manual changeover as long as the control matches that of the PTAC unit.
Desk Control Terminals The Friedrich PD model PTAC has built-in provisions for connection to an external switch to control power to the unit. The switch can be a central desk control system or even a normally open door switch. For desk control operation connect one side of the switch to the D1 terminal and the other to the D2 terminal.

REFRIGERATION SEQUENCE OF OPERATION A good understanding of the basic operation of the refrigeration system is essential for the service technician. Without this understanding, accurate troubleshooting of refrigeration system problems will be more diffi cult and time consuming, if not (in some cases) entirely impossible. The refrigeration system uses four basic principles (laws) in its operation they are as follows: 1.
R-410A SEALED REFRIGERATION SYSTEM REPAIRS SEALED SYSTEM REPAIRS TO COOL-ONLY MODELS REQUIRE THE INSTALLATION OF A LIQUID LINE DRIER. SEALED SYSTEM REPAIRS TO HEAT PUMP MODELS REQUIRE THE INSTALLATION OF A SUCTION LINE DRIER. EQUIPMENT REQUIRED: 1. Voltmeter 2. Ammeter 3.
Method Of Charging / Repairs The acceptable method for charging the RAC system is the Weighed in Charge Method. The weighed in charge method is applicable to all units. It is the preferred method to use, as it is the most accurate. The weighed in method should always be used whenever a charge is removed from a unit such as for a leak repair, compressor replacement, or when there is no refrigerant...
After the unit has run 10 to 15 minutes, check the gauge pressures. Gauges connected to system with an undercharge will have low head pressures and substantially low suction pressures. Overcharged Refrigerant Systems Compressor amps will be near normal or higher. Noncondensables can also cause these symptoms.
HERMETIC COMPONENTS CHECK WARNING BURN HAZARD Proper safety procedures must be followed, and proper protective clothing must be worn when working with a torch. Failure to follow these procedures could result in moderate or serious injury. METERING DEVICE Capillary Tube Systems All units are equipped with capillary tube metering devices.
REVERSING VALVE DESCRIPTION/OPERATION WARNING ELECTRIC SHOCK HAZARD Disconnect power to the unit before servicing. Failure to follow this warning could result in serious injury or death. The Reversing Valve controls the direction of refrigerant fl ow to the indoor and outdoor coils. It consists of a pressure- operated, main valve and a pilot valve actuated by a solenoid plunger.
When sluggish or stuck in the mid-position, part of the discharge gas from the compressor is directed back to the suction side, resulting in excessively high suction pressure. Should the valve fail to shift from coooling to heating, block the air fl ow through the outdoor coil and allow the discharge pressure to build in the system.
6. Protect new valve body from heat while brazing with plastic heat sink (Thermo Trap) or wrap valve body with wet rag. Fit all lines into new valve and braze lines into new valve. WARNING EXPLOSION HAZARD The use of nitrogen requires a pressure regulator.
WARNING BURN HAZARD Certain unit components operate at temperatures hot enough to cause burns. Proper safety procedures must be followed, and proper protective clothing must be worn. Failure to follow this warning could result in moderate to serious injury. External Overload With power off, remove the leads from compressor termi- nals.
COMPRESSOR REPLACEMENT Recommended procedure for compressor replacement WARNING RISK OF ELECTRIC SHOCK Unplug and/or disconnect all electrical power to the unit before performing inspections, maintenances or service. Failure to do so could result in electric shock, serious injury or death. Be certain to perform all necessary electrical and refrigeration tests to be sure the compressor is actually defective before replacing.
SPECIAL PROCEDURE IN THE CASE OF MOTOR COMPRESSOR BURNOUT WARNING ELECTRIC SHOCK HAZARD Turn off electric power before service or installation. Failure to do so may result in personal injury, or death. WARNING HIGH PRESSURE HAZARD Sealed Refrigeration System contains refrigerant and oil under high pressure.
