Persons not qualified shall not attempt to install this equipment nor attempt repairs according to these instructions.
MECHANICAL (FOR QUALIFIED SERVICE PERSONNEL ONLY)
PROBLEM | CAUSE | SOLUTION | |
Harmonics, or whining noise. |
| U.G.inoperative……………………………… | Check movement by putting in hot water (110°F |
|
|
| or higher). If no movement, replace. |
| * Debris or restriction in system……………… | Locate the restriction and remove. Flush system | |
|
|
| and clean. |
| * Debris in gas line……………………………… | Remove debris or blow out gas line. | |
|
| Low flow……………………………………… | Scale forming in heat |
|
|
| exchanger and check pool pH and total alkalinity. |
Heater going on and off continuously. |
| Dirty filter……………………………………… | Backwash filter. |
|
| Low water level in pool……………………… | Raise water level. |
|
| External bypass setting out of |
|
|
| adjustment……………………………………. | Adjust bypass |
| * Pressure switch out of |
| |
|
| adjustment…………………………………….. | Adjust pressure switch |
Liming or scale forming on heat |
| Pool water……………………………………… | See Water Chemistry page 2. |
exchanger. |
|
|
|
Sooting |
| High flow rates………………………………… | Reduce by adding manual bypass valve and |
|
|
| adjust by putting thermometer in header (1/4” |
|
|
| NPT) drain opening. Set bypass so thermometer |
|
|
| reads between 105° and 110°F. |
|
| U.G.Inoperative……………………………… | Check movement by putting in hot water (110° |
|
|
| or higher). If no movement, replace. |
| * | Air starvation…………………………………… | Refer to installation instructions. |
| * | Improperventing……………………………… | Follow recommended installation instructions. |
| * Insects or debris clogging |
| |
|
| burner intake ports…………………………… | Clean burners. |
Pilot outage. |
| Low gas pressure……………………………… | Adjust gas pressure. |
|
| Restricted pilot……………………………….. | Clean pilot. |
|
| Weak pilot generator………………………… | Replace pilot. |
Yellow lazy flame |
| Low gas pressure……………………………… | Adjust gas pressure. |
| * Insects or debris clogging |
| |
|
| burner intake ports…………………………… | Clean burners. |
Outer jacket very hot | * Broken refractory caused by |
(paint blistered) | shipping damage or improper combustion…… |
| Excessive sooting of heat |
| exchanger……………………………………... |
Takes long time to heat pool or spa. | Calculate temperature in °/hr………………… |
Filter not running long enough………………
Dirty filter………………………………………
Gas line or meter undersized…………………
Replace refractory panels.
Determine cause of sooting & correct.
Heat rise (°/hr.) = Heater output ÷ (Pool gallonage x 8.33) or refer to heater sizing chart.
This does not take into account heat loss due to weather.
Reset time clock. Clean filter.
Refer to installation instructions.
(*Usually occurs on initial start-up)
