8. Attaching refrigeration lines.

Line up the piping connections. Energize the liquid line solenoid valve, connect Dry Nitrogen, and adjust to a slight flow through the tubing, being sure no pressure develops in the piping. Connect flare fittings if a flare fitting model, tighten securely, braze other fittings, leak check, evacuate to 200 microns, charge with R-134 refrigerant, start and check out. Using wire ties, secure tubing as low as possible in the evaporator so tubing is not visible through air inlet grille.

Note: Be sure the tubes do not stick out beyond the evaporator opening

for the front panel.
