— Replacement of the refrigeration cycle.
1. When replacing the refrigeration cycle, be sure to
discharge the refrigerant system using a Freon
TM
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.
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 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.
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.
NOTES
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.

3.2 INSTALLATION
• 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.
ITEMS IN INSTALLATION HARDWARE
You may not need all parts in the kit. Discard unused
parts
HOW TO INSTALL
Before installing the unit, identify the existing wall sleeve
from the list below.
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.
Remove old air conditioner from existing wall
sleeve.
Clean the interior of an existing sleeve.
(Do not disturb existing seals or gaskets.)
Wall sleeve must be securely fastened in wall
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.
If you plan to use your existing wall sleeve, and it
is not the FRIEDRICH USC sleeve, use procedure
B or C below.
Install new unit into wall sleeve.
CAUTION: When installation is completed,
replacement unit MUST have a rearward slope as
shown.
