When pump stops from a sudden shadow on the solar array
If a shadow suddenly passes over the array, like if you walk in front if it, the controller will lose track of
the input voltage. It may make rapid on/off noises and a high-pitched noise, then stop. This does NOT
indicate a problem. The pump will attempt to restart after the normal delay.
Time delays
1. After pump stops due to insufficient sunshine or overload fault – 90 SECONDS or less
2. After full-tank float switch resets – 20 SECONDS or less
3. After low-water probe regains contact with water in the source – 20 MINUTES but the indicator light
will stay on for the rest of the day, or until power is disrupted.
To force a quick start
To test or observe the system, you can bypass the normal time delays. Switch the on/off switch (or the
power source) off for about 2 seconds, then on again. The pump should start immediately if sufficient
power is present.
No-load shutoff
If the pump runs out of water, it will run for about 40 seconds, then it will stop. This is the controller’s
normal response when there is no load on the motor. It will attempt to restart every 30-90 seconds.
8 MAINTENANCE
8.1 Pum p Maintenance
The pump requires little or no regular service other than reasonable care and periodic cleaning of the
strainer basket.
Strainer basket To remove debris from the strainer basket, unscrew the lock ring and the clear lid and
lift out the basket. Never operate the pump without the strainer basket.
If frequent cleaning is a nuisance, add a larger strainer or make some improvement in the system to
prevent excessive debris from accumulating.
Keep the motor area clean The motor requires free air circulation to prevent overheating. Keep the
area around the motor free of dry leaves or other debris. If debris accumulates naturally, add some
shelter around the pump to prevent accumulation.
Shaft seal The shaft seal on the pump shaft is a high quality carbon-ceramic mechanical seal. The seal
may wear during the course of, time, particularly if there is abrasive silt in the water. If water continually
leaks out, a new mechanical seal should be fitted.
To replace a mechanical seal, remove the eight bolts holding the casing to the seal housing. Slide the
motor part including the seal housing out. Remove the impeller by turning it counter-clockwise when
facing it, while holding motor shaft at rear end of motor. Slide seal from impeller shaft. To re-assemble,
reverse the process. Note: Make sure both parts of the mechanical seal (ceramic and spring portion) are
clean. Gently wipe polished faces with soft and dry cotton cloth. Surfaces can easily be damaged by dirt
and scratching. Only water should be used as lubricant to mount both parts of the mechanical seal.
