• OPERATION

REMOTE CONTROL SIGNAL RECEIVER

TEMPERATURE SETTING

• Use this button to automatically control the temperature of the room.

The temperature can be set within a range of 60° F to 86° F by increments of 1° F.

POWER

TIMER

- SHUT-OFF TIME

You will usually use shut-off time while you sleep.

With unit running, use Timer to set number of hours until shut-off.

For your sleeping comfort, once Time is set, the Temperature setting will raise 2° F after 30 min., and 2° F after another 30 min.

Every time you push Timer button, it advances the Timer setting as follows: 1 Hour 2 Hours .... 12 Hours maximum.

- START TIME

With unit not running, use Timer to set number of hours before unit starts.

Every time you push Timer button, it advances the Timer setting as follows: 1 Hour 2 Hours ..... 12 Hours maximum.

To turn the air conditioner ON, push this button.

To turn the air conditioner OFF, push the button again.

This button takes priority over any other button.

When you first turn it on, the unit is in cool mode, at High fan speed, and set at a temperature setting of 72° F.

FAN SPEED

Every time you push this button, it advances the setting as follows:

{High → Low → Med → High}

MODE

-Every time you push this button, the air conditioner alternates between COOL, MONEY SAVER® and FAN.

-MONEY SAVER:

The fan stops when the compressor stops cooling. Approximately every 3 minutes the fan will turn on and the unit will check the room air to determine if cooling is needed.

• VENTILATION

Push the lever to the "CLOSE" position to cool, heat or recirculate room air only.

Pull the lever to the "OPEN" position to exhaust smoke or stale air from the room.

This feature is best used in conjunction with the FAN ONLY

position. PULL OPEN / PUSH CLOSE

—6—

1.5.2 COOLING AND HEATING MODEL

• OPERATION

Off

- Turns the air conditioner off.

Fan Only

- The low fan speed operation without cooling (heating).

Low Cool

- Cooling with the low speed fan operation.

High Cool

- Cooling with the high speed fan operation.

Low Heat

- Heating with the low speed fan operation.

High Heat

- Heating with the high speed fan operation.

Turn the Temperature Knob to the desired setting. The central position is a normal setting for average conditions. You can change this setting, if necessary, in accordance with your temperature preference.

The thermostat automatically controls cooling or heating, but the fan runs continuously whenever the air conditioner is in operation. If the room is too warm, turn the thermostat control clockwise. If the room is too cool, turn the thermostat control counterclockwise.

CAUTION

When the air conditioner has been operating in the cooling or heating mode and is turned off or set to the fan only position, wait at least 3 minutes before resetting to the cooling operation again.

A slight burning odor may come from the unit when first switching to HEAT after the cooling season is over. This odor, caused by fine dust particles on the heater, will disappear quickly. This is normal operation.

NOTES

Replacement of the refrigeration cycle.

1.When replacing the refrigeration cycle, be sure to discharge the refrigerant system using a FreonTM recovery System.

If there is no valve to attach the recovery system, install one (such as a WATCO A-1) before venting the FreonTM. Leave the valve in place after servicing the system.

2.After discharging the unit completely, remove the desired component, and unbrace the pinch-off tubes.

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.

1)Connect the vacuum pump, as illustrated Fig. 18A.

2)Start the vacuum pump, slowly open manifold valves A and B with two full turns counterclockwise and leave the valves closed. The vacuum pump is now pulling through valves A and B up to valve C by means of the manifold and entire system.

CAUTION

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 Fig. 18B. Open valve C.

Discharge the line at the manifold connection.

5)The system is now ready for final charging.

6.Recharge as follows :

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 Fig. 18B. With valve C open, discharge the hose at the manifold connection.

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.

5)With the unit running, open valve B and add the balance of the charge.

a.Do not add the liquid refrigerant to the Lowside.

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.

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.

3.2 INSTALLATION

CAUTION

We strongly recommend the removal of the old wall sleeve and the installation of a new FRIEDRICH USC Wall Sleeve.

If you decide to keep the existing wall sleeve, you have to redirect the louvers at the back of the wall sleeve illustration. The use of pliers is recommended. If you DO NOT redirect, you run the risk of poor performance or product failure. This is not covered under the terms of the FRIEDRICH warranty.

Pick a location which will allow the conditioned air to blow into the area you want. Good installation with special attention to the proper position of the unit will lessen the chance that service will be needed.
