Removal and replacement procedures 84
Replacing the magnetic solenoid valve
1. Using a Phillips screwdriver, connect the electrical connector from the MCS unit to the magnetic
solenoid by inserting and tightening one Phillips screw.
2. Adjust the water hoses connected to the rear of the bottom heat exchanger unit and hold them out of
the way to reach the solenoid valve post. This process can be difficult. If you struggle excessively,
disconnect the In and Out water hoses connected to the bottom heat exchanger unit using the
counter hold wrench and the water hose fitting wrench.
3. Place the magnetic solenoid back on the valve post (1), and press down until the silver retainer tab
locks the magnetic solenoid in place on the valve (2).
4. Replace the air deflector plate ("Replacing the air deflector plate" on page 34).
5. Replace the bottom fan unit ("Replacing the bottom fan unit" on page 45).
6. Complete the operation checklist (on page 111).
