POWER BUTTON  
To turn the air conditioner ON. To turn the air conditioner OFF, push the button again.  
This button takes priority over any other buttons.  
TEMPERATURE SETTING BUTTON  
This button can automatically control temperature of the room. The temperature can be set within a range of 60'F to 86'F  
by 1'F.  
OPERATION MODE SELECTION BUTTON  
Every time you push this button, it will shift operation between COOL, ENERGY SAVER, FAN and DRY modes.  
- Money Saver: If Money Save mode is selected, the fan stops when the compressor stops cooling.  
Approximately every 3 minutes the fan will turn on and check the room air to determine if cooling is needed.  
FAN SPEED SELECTOR  
Every time you push this button, it will shift fan speeds, as follows.  
(Hi Low Med Hi Low ...)  
ON/OFF TIMER BUTTON  
ON - When the air conditioner is off,it can be set to automatically come on in 1 to12 hours from its previous setting.  
Each touch will increase the timer by 1 hour.  
OFF - When the air conditioner is on, it can be set to automatically turn off in 1 to 12 hours. Each touch will increase  
the timer by 1 hour. After the timer has been on for 30min, the temperature will automatically rise 2F, and after another  
another 30min, it will rise 2F again. The temperature will stay the same until the timer goes off.  
To cancel the timer, press the timer pad until the display time disappears.

NOTES  
Replacement of the refrigeration cycle.  
6. Recharge as follows :  
1. When replacing the refrigeration cycle, be sure to  
TM  
Discharge the refrigerant system using a Freon  
recovery System.  
1) Refrigeration cycle systems are charged from  
the High-side. If the total charge cannot be put  
in the High-side, the balance will be put in the  
suction line through the access valve which you  
installed as the system was opened.  
2) Connect the charging cylinder as shown in figure  
16B.  
If there is no valve to attach the recovery system,  
install one (such as a WATCO A-1) before venting  
TM  
the Freon . Remove the valve when finished.  
2. After discharging the unit completely, remove the  
desired component, and unbraze the pinch-off  
tubes.  
With valve C open, discharge the hose at the  
manifold connection.  
3. Solder service valves into the pinch-off tube ports,  
leaving the valves open.  
4. Solder the pinch-off tubes with Service valves.  
5. Evacuate as follows.  
3) Open valve A and allow the proper charge to  
enter the system. Valve B is still closed.  
4) If more charge is required, the high-side will not  
take it. Close valve A.  
1) Connect the vacuum pump, as illustrated figure  
16A.  
5) With the unit running, open valve B and add the  
balance of the charge.  
2) Start the vacuum pump, slowly open manifold  
valves A and B with two full turns  
a. Do not add the liquid refrigerant to the Low-  
side.  
counterclockwise and leave the valves open.  
The vacuum pump is now pulling through valves  
A and B up to valve C by means of the manifold  
and entire system.  
b. Watch the Low-side gauge; allow pressure to  
rise to 30 lbs.  
c. Turn off valve B and allow pressure to drop.  
d. Repeat steps b. and c. until the balance of the  
charge is in the system.  
CAUTION  
6) When satisfied the unit is operating correctly,  
use the pinch-off tool with the unit still running  
and clamp on to the pinch-off tube. Using a tube  
cutter, cut the pinch-off tube about 2 inches from  
the pinch-off tool. Use sil-fos solder and solder  
pinch-off tube closed. Turn off the unit, allow it to  
set for a while, and then test the leakage of the  
pinch-off connection.  
If high vacuum equipment is used, just crack  
valves A and B for a few minutes, then open  
slowly with the two full turns counterclockwise.  
This will keep oil from foaming and being  
drawn into the vacuum pump.  
3) Operate the vacuum pump for 20 to 30 minutes,  
until 600 microns of vacuum is obtained. Close  
valves A and B, and observe vacuum gauge for  
a few minutes. A rise in pressure would  
indicate a possible leak or moisture remaining in  
the system. With valves A and B closed, stop  
the vacuum pump.  
4) Remove the hose from the vacuum pump and  
place it on the charging cylinder. See figure  
16B.  
Open valve C.  
Discharge the line at the manifold connection.  
5) The system is now ready for final charging.

Check switch continuity. Refer to wiring diagram for  
terminal identification. Replace switch if defective.  
Wire disconnected or  
connection loose  
Connect wire. Refer to wiring diagram for terminal  
identification. Repair or replace loose terminal.  
Capacitor (Discharge  
Test capacitor.  
capacitor before testing.)  
Replace if not within 10% of manufacturer's rating.  
Replace if shorted, open, or damaged.  
Will not rotate  
Fan blade hitting shroud or blower wheel hitting  
scroll. Realign assembly.  
Units using slinger ring for condenser fan must have  
1/4 to 5/16 inch clearance to the base. If it hits the  
base, shim up the bottom of the fan motor with  
mounting screw(s).  
Check fan motor bearings; if motor shaft will not  
rotate, replace the motor.  
Fan motor runs  
intermittently  
Revolves on overload.  
Check voltage. If not within limits, call an electrician.  
Test capacitor.  
Check bearings. Does the fan blade rotate freely?  
If not, replace fan motor.  
Pay attention to any change from high speed to  
low speed. If the speed does not change, replace the  
motor.  
Fan  
If cracked, out of balance, or partially missing,  
replace it.  
Fan motor noise.  
Blower  
If cracked, out of balance, or partially missing,  
replace it.  
Loose clamper  
Worn bearings  
Tighten it.  
If knocking sounds continue when running or loose,  
replace the motor. If the motor hums or noise  
appears to be internal while running, replace motor.  
Voltage  
Wiring  
Check voltage.  
If not within limits, call an electrician.  
Compressor will not run,  
but fan motor runs.  
Check the wire connections, if loose, repair or  
replace the terminal. If wires are off, refer to wiring  
diagram for identification, and replace. Check wire  
locations. If not per wiring diagram, correct.  
Rotary  
Check for continuity, refer to the wiring diagram for  
terminal identification. Replace the switch if circuit is  
open.

COMPLAINT  
CAUSE  
Thermostat  
REMEDY  
Compressor will not run,  
but fan motor runs.  
Check the position of knob. If not at the coldest  
setting, advance the knob to this setting and restart  
unit.  
Check continuity of the thermostat. Replace  
thermostat if circuit is open.  
Capacitor (Discharge  
Check the capacitor.  
capacitor before servicing.) Replace if not within 10% of manufacturers rating.  
Replace if shorted, open, or damaged.  
Compressor  
Check the compressor for open circuit or ground. If  
open or grounded, replace the compressor.  
Overload  
Check the compressor overload, if externally  
mounted. Replace if open. (If the compressor  
temperature is high, remove the overload, cool it,  
and retest.)  
Compressor cycles on  
overload.  
Voltage  
Check the voltage.  
If not within limits, call an electrician.  
Overload  
Check overload, if externally mounted.  
Replace if open. (If the compressor temperature is  
high, remove the overload, cool, and retest.)  
Fan motor  
If not running, determine the cause. Replace if  
required.  
Compressor cycles on  
overload.  
Condenser air flow  
restriction  
Remove the cabinet. inspect the interior surface of  
the condenser; if restricted, clean carefully with a  
vacuum cleaner (do not damage fins) or brush.  
Clean the interior base before reassembling.  
Condenser fins (damaged) If condenser fins are closed over a large area on the  
coil surface, head pressures will increase, causing  
the compressor to overload. Straighten the fins or  
replace the coil.  
Capacitor  
Test capacitor.  
Compressor cycles on  
overload.  
Wiring  
Check the terminals. If loose, repair or replace.  
Check the system for a restriction.  
If restricted, clean of replace.  
Close if open.  
Refrigerating system  
Air filter  
Insufficient cooling or  
heating  
Exhaust damper door  
Unit undersized  
Determine if the unit is properly sized for the area to  
be cooled.  
Excessive noise  
Blower or fan  
Copper tubing  
Check the set screw or clamp. If loose or missing,  
correct. If the blower or fan is hitting air guide,  
rearrange the air handling parts.  
Remove the cabinet carefully and rearrange tubing  
not to contact cabinet, compressor, shroud, and  
barrier.
