NOTE: If DIP switch is set for Stage 2, the alarm relay will not cycle during Test mode. Heating/Cooling Thermostat Type — Switch 3 provides selection of thermostat type. Heat pump or heat/cool thermostatscan be selected. Select OFF for heat/cool thermostats. When inheat/cool mode, Y1 is used for Cooling Stage 1, Y2 is used forCooling Stage 2, W1 is used for Heating Stage 1 and O/W2 isused for Heating Stage 2. Select ON for heat pump applications. In heat pump mode, Y1 used is for Compressor Sta

See Fig. 61. The holes in the sampling tube face downward, into the return air stream. The sampling tube is connected via tubing to the return air sensor that is mounted on a bracket high on the partition between return filter and controller location. (This sensor is shipped in a flat--mounting location. Installation requires that this sensor be relocated to its operating location and the tubing to the sampling tube be connected. See the following installation procedure.) Return Air Sampling Tub

Construct platform using drainage and clearance recommendations above. Locate and construct platform to avoid possible transfer of unit vibration to structure. ON THE ROOF: MOUNT OUTDOOR COIL ON A LEVEL PLATFORM OR FRAME. Unit must be elevated for proper clearance as described under ground installation above. Roof design and water drainage must be planned to prevent units from setting in water. Flash all roof openings to prevent leaks. Step 3 — Mount Indoor Compressor Section on a rigid, soli

The point on the network where the installation is to be made may often be of importance in obtaining a ruling, so approval in one case may not hold true for the entire network. The starting torque which a motor develops is approximately proportional to the square of the voltage at the motor terminals. Thus, at half voltage, a motor will develop only one-quarter of the torque that it will develop at full voltage, or .50 x .50 = .25. To make starting possible, the voltage at the motor terminals

It puts the weather to work for you and lowers operating costs. Thermodynamically, there is no difference between a heat pump and an air conditioning unit or refrigerator. The heat pump moves heat from a colder heat source to a warmer heat sink thru the vapor compression cycle. (The same as a refrigerator or air conditioner.) The difference, from a practical standpoint, is in the heat pump's ability to reverse the roles of the evaporator and condenser coils. The heat pump takes advantage of t

Lift grille from unit. 4. Disconnect compressor leads (crankcase heater, low-pressure switch, defrost thermostat and solenoid coil) from electrical components and pull them thru the wire access opening into the PRESSURE AT LIQUID SERVICE VALVE coil section. Lift fan orifice/control ring after pinching and pressing down on 3 plastic pins of tube supports. 5. Remove louvered casing by taking out 16 screws securing it to the cabinet and sliding it away from the coil. 6. Using a midget tubing c
