Air Conditioning Current Check.
Analysis of any air conditioner system would not be complete without performing a check on the amount of current being drawn by the compressor. The amount of load or work being done by the compressor is in direct relation to the amount of amperes or current being consumed.
The performance chart shows the normal amount of current the compressor should draw, and allowing for local variations in temperatures and humidity, the serviceman can utilize the current data as an aid to diagnose certain troubles.
Abnormally high ampere draw would indicate trouble in one or more of the following areas:
1. Recirculation of condenser air.
2. Obstruction of condenser air.
3. Leaking or partially shorted running capacitor.
3. Partially shorted or grounded compressor winding.
4. Overcharged system.
Abnormally low ampere draw would indicate trouble in one or more of the following areas:
1. Clogged intake filter.
2. Dirty evaporator coil.
3. Recirculation of evaporator air.
4. System partially discharged—refrigerant leak.
5. Partially restricted capillary.
6. Partially restricted strainer.
8. Inefficient compressor.
Installation of Thru-The-Wall-Type Air Conditioners
The unit may be installed in walls up to nine inches thick.
Procedure. Remove unit from shipping carton, remove tape holding decorative front in place, remove front and place out of the way; slide unit out of shell.
Layout. Cut and frame-in an opening in the desired wall area. Remove two screws and relocate sill plate back one inch to next set of holes in shell rail. Place shell in the wall opening with the front flange tight against the wall surface. Drill three against diameter pilot holes. Secure with three Phillips screws. Attach brackets to shell with screws and nuts furnished lower end of support brackets to wall. If other than wood construction, use a piece of 2 X 4 lumbers to attach support brackets. Caulk all around shell on outside to insure a weather tight seal. Slide unit into shell. Place filter in position. Place decorative front in position on shell and secure with two slotted sheet-metal screws. Plug service cord into electrical outlet. A larger attic fan is required in the white area or -horsepower, 42-inch fan that will normally provide 60 air changes per hour for the average three-bedroom house. Window fans are usually smaller. They range in size from 20 to 30 inches. The 20-inch size is the most popular.
