NOTES

Replacement of the refrigeration cycle.

1. When replacing the refrigerating cycle, be sure to discharge the refrigerant by using a refrigerant recovery system.

2. After discharging the unit completely, remove the desired components, and unbraze 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. After completing the above procedures, the valve must be closed and left in place on the system for any subsequent procedures.

6. Evacuate as follows:

7. Connect the vacuum pump, as illustrated in figure 21A.

8. 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 manifold and the 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 counter-clockwise. This will keep oil from foaming and being drawn into the vacuum pump.

9. Operate the vacuum pump for 20 to 30 minutes, until 600 micron 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.

10. Remove the hose from the vacuum pump and place it on the charging cylinder. See figure 23B. Open valve C. Discharge the line at the manifold connection.

11. The system is now ready for final charging.

12. Recharge as follows:

13. Rotary compressor 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 is installed as the system is opened.

14. Connect the charging cylinder as shown in figure 21B. With valve C open, discharge the hose at the manifold connection.

15. Open valve A and allow the proper charge to enter the system. Valve B is still closed.

16. If more charge is required, the high-side will not take it. Close valve A.

17. 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 the pressure to drop.
  * d. Repeat steps B and C until the balance of the charge is in the system.
6. When the unit is operating correctly, use the pinch-off tool with the unit still running and the clamp on 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 the pinch-off tube closed. Turn off the unit, allow setting for a while and then test the leakage of the pinch-off connection.

Equipment needed: Vacuum pump, charging cylinder, manifold gauge, brazing equipment, pinch-off tool capable of making a vapor proof seal, leak detector, tubing cutter, hand tools to remove components and service valve.

INSTALLATION

This air conditioner is designed with a button-down chassis so it can be easily installed in a window.

SELECT THE BEST LOCATION

1. To prevent vibration and noise, make sure the unit is installed securely and firmly.

2. Install the unit where the sun does not shine directly on the unit.

3. The outside of the cabinet must extend outward for at least 25.4cm(10″) and there should be no obstacles, such as a fence or wall, within 50.8cm(20″) from the back of the cabinet because it will prevent heat radiation of the condenser. Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner
   CAUTION
   All side louvers of the cabinet must remain exposed on the outdside of the structure.

4. Install the unit slanted slightly so the back is slightly lower than the front [about 6.35mm(1/4″)]. This will force condensed water to the outside.

5. Install the unit with the bottom about 76.2cm(30″) ~152.4cm(60″) above the floor level.

HOW TO INSTALL

WINDOW REQUIREMENTS

NOTE: All supporting parts should be secured to firm wood, masonry, or metal.

1. This unit is designed for installation in standard double-hung windows with actual opening widths of 55.88cm(22″) to 91.44cm(36″). The upper and lower sash must open sufficiently to allow a clear vertical opening of 30.01cm(13″) from the bottom of the sash to the window stool.
2. If a storm window presents interference, fasten a 5.08cm(2″) wide wood strip to the inner window sill across the full width of the sill. The wood strip should be thick enough to raise the height of the window sill so that the unit can be installed without interference by the storm window frame. See Fig. 24. Top of the wood strip should be approximately 1.9cm(3/4″) higher than the storm window frame (STORM WINDOW FRAME) or wood strip (OUTDOORS) to help condensation to drain properly to the outside.
3. Install a second wood strip (approximately 15.24cm(6″) long by 3.81cm(11/2″) wide and the same thickness as the first strip) in the center of the outer sill flush against the back off the inner sill. This will raise the L bracket as shown in Fig. 24. The thickness of the second wood strip may not be the same as the first wood strip. The thickness of the second wood strip must be defined to keep the 1.9cm(3/4″) distance between the inner sill or the top of the first wood strip and the outer sill.

Installation

BEFORE INSTALLATION

1. Insert the guide panels into the guides of the air conditioner. Fasten the curtains to the unit with screws (TYPE A), as shown Fig. 25.
