NOTES

— Replacement of the refrigerant.

1. When replacing the refrigerant, be sure to discharge the refrigerant system using a Freon 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 unbraze the pinch-off tubes.

3. Braze service valves into the pinch-off tube ports, leaving the valves open.

4. Braze the pinch-off tubes with Service valves.

5. Evacuate as follows.

1) Connect the vacuum pump, as illustrated figure

20A.

2) Start the vacuum pump, slowly open manifold

valves A and B with two full turns 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.

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 figure 20B. Open valve C. Discharge the line at the manifold connection.

5) The system is now ready for final charging.

TM

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 figure 20B. 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.

3.1 HOW TO INSTALL THE UNIT

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

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

3. The outside of the cabinet must extend outward and there should be no obstacles, such as a fence or wall, within 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 to the outside of the structure.

4. Install the unit a little slanted so the back is slightly lower than the front (about 1/4"). This will force condensed water to flow to the outside.

5. Install the unit with the bottom about 30"~60" above the floor level.

Figure 21

3.2 CHECK OF INSTALLATION

The setting conditions must be checked prior to initial starting.

The undermentioned items are especially important checking points when the installation is finished.

1. Grounding wire (Green or Green and Yellow) is provided in the power cord. The green wire must be grounded.

2. Connect to a single-outlet 15A circuit. (or 21A circuit for Electric Heater Model)

3. To avoid vibration or noise, make sure the air conditioner is installed securely.

4 Avoid placing furniture or draperies in front of the

air inlet and outlet.

3.3 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 from 26" to 39 3/8".

3.6 HOW TO INSTALL

CAUTION

To avoid the possibility of personal injury, unplug power to unit before installing or servicing.

Carefully remove air conditioner from carton, check for possible shipping damage. Pick a location which will allow you to blow the cold air into the area you want. Windows used for installation must be strong enough to support the weight of the air conditioner. Good installation with special attention to the proper position of the unit will lessen the chance that service will be needed. When cooling more than one room, installation location is very important. To cool your rooms, cold air must be blown from the air conditioner in a straight path. If air conditioner is blocked by a storm window frame, see Step 7 and 8 on Page 14 before beginning to install.

1. Cut the FOAM STRIP (ITEM G) to fit the underside of the window sash. Open the window, peel off the backing and attach the FOAM STRIP as shown in Figure 23.

• If storm window presents interference, fasten a 2"(51mm) 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 unit can be installed without interference from the the storm window frame. See Figure 30. Top of wood strip should be approximately 3/4"(19mm) higher than the storm window frame to help condensation to drain properly to the outside.

• Install a second wood strip (approximately 6"(152mm) long by 11/2"(38mm) wide and same thickness as first strip) in the center of the outer sill flush against the back of the inner sill. (Figure 30)

8. INSTALLATION FOR OTHER TYPE WINDOWS.

• Dimensions and geometry of windows are different depending on their manufacturing. Check your window and refer to FIG.31 to install the support bracket firmly.
