3. On water-cooled model, remove the water from the water-cooled condenser:
1) Make sure the power supply is off, then remove the front, top, and right side panels.
2) Close the condenser water supply line shut-off valve. If connected to a closed loop
system, also close the condenser return line shut-off valve.
3) Open the condenser water supply line drain valve. If connected to a closed loop system,
also open the condenser return line drain valve.
4) Attach a compressed air or carbon dioxide supply to the condenser water supply line
drain valve.
5) Open the water regulating valve by using a screwdriver to pry up on the spring retainer
underneath the spring. While holding the valve open, blow out the condenser using the
compressed air or carbon dioxide supply until water stops coming out.
