SolarAttic PCS1, User Manual

Page: 97 / 116

SECTION 4 - SERVICE Page S4-10
EXCESSIVE VIBRATION 1. Unbalanced fan blade.
2. Loose fan blade.
3. Loose motor mounting or cabinet hardware.
4. Lack of foam base for PCS1 to rest on.
5. Rigid mounting PCS1 to building structure.
6. Contamination on fan blade causing imbalance.
7. Motor bearings defective.
HIGH PRESSURE AT
FILTER
Note: Total
pressure should be less than
25-30 lbs in the typical
installation with a clean filter.
1. Backwash and clean filter.
2. Check position of valves within support system. Incorrectly
positioned valves can restrict water flow and increase pressure with the
system.
3. Contact pool servicer. Problem is not in PCS1 system.
POOR CIRCULATION
Note: pool water gets cloudy.
1. Clean filter.
2. Check valve positions.
3. Check water flow rate from pump.
4. Check pump sizing.
5. Contact pool servicer. Problem is not in PCS1 system.
HIGH ELECTRIC BILL 1. Check to see how many hours the filter pump is running.
2. Check the condition and size of the filter pump.
3. Wire the filter pump to the LX220 power relay and use a minimum
runtime timer to ensure that only a minimum filtration time is achieved.
Place LX220 in AUTO. This combination maximizes solar collection and
minimizes the energy required to accomplish it.
4. Problem is not the PCS1. It only draws 1.8 amps maximum and its
energy use is easily determined within a range of $3.00 minimum to
$20.00 Maximum per month depending upon local electricity rates. At
9¢ per kilowatt hour and 10 hours per day, the PCS1 will cost an
estimated $11.00 per month to operate.
5. Have an energy audit performed.
