WARNING

Dangerous Chemical Pressurized Refrigerant is used during the operation of this

equipment.

Use great care to avoid contact with liquid refrigerant or inhaling refrigerant gas being

discharged from any container under pressure. Sudden and irreversible tissue damage can

result from freezing. Wear thermal protective gloves and a face protector or safety glasses

in any situation where skin or eye contact is possible.

Heat causes the refrigerant to break down and from carbonyl chloride (phosgene), a

highly toxic and corrosive gas. Avoid contact between refrigerant gas and a flame or

other hot surfaces.

NOTE

The charging operation should be done with all panels in place except for refrigerant

charging valve access cover. Use recycled refrigerant whenever possible.

FULL CHARGE

1. Connect the 1/4 inch yellow hose (charge) to a cylinder of R-22 set to deliver gas only.

2. Slightly loosen hose connections on the HIGH and LOW pressure charging valves.

3. Ensure the vacuum and charge valves are closed.

4. Open the pressure gauge and compound gauge valves.

5. Open the refrigerant cylinder valve.

6. Slightly open the charge valve to allow a small amount of refrigerant to purge air from the hoses. Tighten all hose

connections on the HIGH and LOW pressure charging valves. Close the charge valves.

CAUTION

Severe damage can affect the compressor. Never introduce liquid refrigerant into the low

pressure (suction) charging valves.

7. Close the compound gauge valve.

8. Set the refrigerant cylinder to delive r liquid only.

9. Place the refrigerant cylinder on an accurate scale to measure and record weight.

10. Open the HIGH and LOW-pressure charging valves.

11. Open the charge valve. Allow liquid refrigerant to enter the system until the drum weight has decreased by 2.2

pounds (1.0 kg) for the F9000H-1SA or 2.4 pounds (1.09 kg) for the F9000H-3SA or until the system pressure has

equalized.

12. Close the charge and pressure gauge valves.

13. Reset the low pressure and high-pressure cutout switches.

14. Connect the power at the power source.

15. Turn the air conditioner on and operate in COOL mode with the temperature selector set at the maximum COOLER

position.
