Description of Operation
Alternate Wiring Diagram (A)
POOLÕS ORIGINAL WIRING
This pool was equipped with both a filtration pump and a polaris booster
pump [for cleaning the pool via a polaris vacuum sweep]. Both pumps were wired
directly from the power panel through different [and adjacent] circuit breakers. Each
pump had its own "manual" on/off switch. Each pump was wired to operate off of
110 vac. Because of adjacent circuit breakers being used, 220 vac was present at the
support system manual switch boxes.
WIRING THE LX220
Wiring the LX220 was accomplished directly above the manual on/off
switches. 110 vac was taken from each manual switch for use in the LX220 as 220
vac for the PCS1. The LX220 itself could have been wired to operate from either 110
vac or 220 vac. The PCS1
requires 220 vac at 1.8 amperes.
PUMP OPERATION
The 110 vac from the filtration pump was fed back to the other side of the
manual switch. This allowed automatic operation or manual operation of the
filtration pump.
POLARIS VAC SWEEP OPERATION
Operation of the polaris vac sweep is accomplished manually when both
switches are on. During this cleaning operation, solar heat collection occurs
automatically when the bypass valve turns on routing the pool's water through the
PCS1. Automatic operation of the polaris vac sweep can be accomplished via a
second internal sweep relay inside the LX220 [optional].
CAUTION NOTES :
The booster pump must not be operated when the filter pump is off and the
PCS1 should not be equipped with a solar drain down kit unless a sweep delay relay
is used in the LX220 to delay the startup of the booster pump! This prevents air
bubbles from getting into the booster pump during PCS1 startup.
