NOTES  
Replacement of the refrigeration cycle.  
1. When replacing the refrigeration cycle, be sure to  
discharge the refrigerant system using a FreonTM  
recovery System.  
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 Low-  
side.  
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.  
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.  
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.  
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.

FRIEDRICH USC Wall Sleeve  
FIG. 20B  
Carefully inspect location where air conditioner will be  
installed. Be sure it will support the weight of the unit  
over an extended period of time.  
ELECTRICAL SERVICE  
Handle air conditioner with care. Wear protective gloves  
whenever lifting or carrying the unit. AVOID the sharp  
metal fins of front and rear coils.  
Check your available electrical service. The power supply  
available must be the same as that shown on the unit  
nameplate (found on left side of cabinet).  
Make sure air conditioner does not fall during installation.  
All models are equipped with a 3-prong service plug to  
provide proper service and safe positive grounding. Do not  
change plug in any way. Do not use an adapter plug. If your  
present wall outlet does not match your plug, call a qualified  
electrician to make the necessary corrections. SAVE  
CARTON for storage and this OWNER'S MANUAL for future  
reference. The carton is the best way to store unit during  
winter or when not in use.  
REQUIRED TOOLS:  
3/8-inch open end

NOTE: All wall sleeves used to mount the new Air  
Conditioner must be in sound structural condition and  
have a compatible rear grille that securely attaches to  
sleeve, or rear flange that serves as a stop for the Air  
Conditioner.  
3.2 INSTALLATION  
CAUTION  
We strongly recommend the removal of the  
old wall sleeve and the installation of a new  
FRIEDRICH USC Wall Sleeve.  
Remove old air conditioner from existing wall  
2
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.  
Clean the interior of an existing sleeve.  
(Do not disturb existing seals or gaskets.)  
3
Wall sleeve must be securely fastened in wall  
4
before installing the air conditioner. Use the nails  
or screws through the sides of the sleeve into wall,  
if needed. Repaint sleeve if needed.  
Prepare the wall sleeve for installation of the unit.  
5
If you plan to use your existing wall sleeve, and it  
is not the FRIEDRICH USC sleeve, use procedure  
B or C below.  
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.
