IMPORTANT
Always install a new Drier every time the sealed refrigeration system is opened.
Do not replace the Drier until after all other repairs or replacement have been made.
1) Turn off the power supply.
2) Remove the panels and the Top Insulation over the Evaporator.
3) Recover the refrigerant and store it in an approved container.
4) Remove the Spray Tubes and the Insulations at the “U” shaped notch where the
     refrigeration tubings pass through the molded chassis.
5) Remove the Insulation Tube, and disconnect the Evaporator Inlet Tubing at the Tee next
     to the Expansion Valve.
6) Lift up the Evaporator, and disconnect the Evaporator Outlet Tubing.
7) Install the new Evaporator.
8) Install the new Drier.
9) Check for leaks using nitrogen gas (140 PSIG) and soap bubbles.
10) Evacuate the system, and charge it with refrigerant.  For water-cooled models, see the
       Nameplate for the required refrigerant charge.  For remote air-cooled models, see the
       Charge Label in the machine compartment.
11) Replace the removed parts in the reverse order of which they were removed.
12) Replace the Top Insulation and the panels in their correct positions.
