Page 8: Display
Display Display LED display 1. POWER Press this button to switch the unit on or off 2. FUNCTION Press this button to select between Cooling ( ), Heating ( ) or Dehumidifying ( ) mode 3. TEMP+ Pressing this button in cooling mode adjusts the required room temperature by 1°C up to a maximum temperature of 30°C. - Page 9 Display (Automatic)”. If “AUTO” is selected, the ventilator operates at temperature differences larger than 9 degrees at top speed. If the temperature reduces to a difference smaller than 4 degrees, the ventilator switches to middle blower position. If the temperature reduces further until the target temperature, the ventilator switches to the lowest blower position.

Page 21: Basic Test Procedure
Basic test procedure Basic test procedure 11.1 Defective compressor Compressors are single phase, 115 or 120 volt, depending on the model unit. All compressor motors are permanent split capacitor type using only a running capacitor across the start and run terminal. -
Page 22: Sealed Refrigeration System Repairs
Basic test procedure If test shows: A. Below normal high side pressure. B. Above normal low side pressure. C. Low temperature difference across coil. The compressor valves are faulty - replace the compressor. 11.1.4 Terminal overload (external) Some compressors are equipped with an external overload which is located in the compressor terminal box adjacent to the compressor body The overload is wired in series with the common motor terminal. - Page 23 Basic test procedure 5. Vacuum Pump (capable of 200 microns or less vacuum.) 6. Acetylene Welder 7. Electronic Halogen Leak Detector (G.E. Type H-6 or equivalent.) 8. Accurate refrigerant charge measuring device such as: a. Balance Scales - 1/2 oz. accuracy b. Charging Board - 1/2 oz.

Page 24: Fan Motor
Basic test procedure small increments while operating the unit. 12. Restart unit several times after allowing pressures to stabilize. Pinch off process tubes, cut and solder the ends. Remove pinch off tool, and leak check the process tube ends. 11.2.4 Special procedure in the case of compressor motor burnout. -
Page 25: Capacitor
Basic test procedure 4. Apply "live" test cord probes on red wire and common terminal of capacitor. Motor should run at low speed. 5. Apply "live" test cord probes on each of the remaining wires from the speed switch or system switch to test intermediate speeds. -
