SECTION 4 - SERVICE Page S4-2
SERVICE NOTES
The PCS1 is maintenance free and requires only occasional inspection to
ensure everything is working properly. Here are some suggestions:
1. Inspect the PCS1 coil annually during spring startup or fall winterization
for any accumulation of dust or debris from attic environment. Vacuum any
accumulated dust off of the coil fins. This is not normally a problem.
2. Any time service is performed inside the PCS1, disconnect power first.
3. Any time the front grille or a side panel is off the PCS1, inspect to ensure
proper operation of the float. This is indicated by the float being free to move. If the
float switch was defective [open], the automatic mode of the LX220 would not work.
Also, the Òsolar sensor service reqdÓ light on the LX220 control panel will be on. No
debris or obstruction of the float should be present during this examination.
4. Do not lubricate the motor.
5. During startup, listen to the fan and motor. There should be mostly air
flow noise associated with the fan. No bearing noise should be apparent. If so, the
motor may need to be changed.
6. Some evidence of a small amount of condensate will be present in the
form of a water stain in the interior of the PCS1 base pan. This is normal.
7. CAUTION : When working on the PCS1 where the inlet and/or outlet
union(s) will be disconnected, ensure that (A) the bypass valve is in the ÒOFFÓ
position bypassing the PCS1; (B) the controller is ÒOFFÓ; (C) the plug to the bypass
valve operator is removed; and, (D) the manual handle for the bypass valve is
removed. These precautions will prevent the pool water from accidentally being
routed up to the attic during service. When reconnecting the plug to the VOR,
ensure it shows ÒPoolÓ up the same as it was when it was removed [SPA up if the
valve was reverse staged]. A reversed staged valve has inlet and outlets reversed.
