High voltage can kill.
1. Discommct power supply.
2. Remove 16 screws and rain seal washers, and canvas cover.
3. Remove 11 screws and rain seal washers, and top panel.
4. Remove two screws and access cover.
Use great care to avoid contact with liquid refrigerant or 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.
Prevent contact of refrigerant gas with flame or hot metal surfaces.
Heat causes the refrigerant to break down and form carbonyl
chloride (phosgene), a highly toxic and corrosive gas. In case of
refrigerant leaks, ventilate area immediately.
5. Visually inspect expansion valve (4) for damage. Check for evidence of leakage.
1. Tape a thermometer to the tubing near the expansion valve sensing bulb.
2. Connect a charging manifold low pressure (suction) hose to the low pressure
service valve. See Figure 5-12. Make sure the high pressure hose and the center hose on the
charging manifold are either capped or plugged. Close the manifold valves.
3. Connect the power supply and turn the mode selector switch to COOL and
temperature selector switch to maximum INCREASE.
