C A U T I O N : Some pool pumps were sized smaller and set up to run 24 hours
per day for proper filtration. If the pool water is getting cloudy and a timer is
not used, manual operation of the pump may be required for proper
filtration. Or, the pump may be upgraded to provide proper filtration
without running 24 hours a day. See discussion on pump sizing in
ÒCommon Questions.Ó
14. Use a separate circuit breaker for the poolÕs support system which includes
power to the LX220 and the PCS1 via the LX220.
15. The LX220 is UL listed.
16. Option: Use a manual bypass switch for the PCS1 power to manually turn
the fan on without activating the solar controller. This is useful for ventilating the
attic without heating the pool. An alternative method is to unplug the bypass
valveÕs valve operator [VOR] so it doesnÕt route water to the PCS1 and then turning
the LX220 to
ON [manual override]. This also turns the fan on.
17. Use a pump manual bypass switch for manual pump operation.
18. DO NOT DIRECT WIRE THE PCS1. Use an outlet box in the attic so the
unit can be unplugged for service needs. Use a double pole cutoff switch for
attic power as an additional safety feature if desired.
19. Some pumps may be wired to run off 110 vac. The pump is usually the
source of power for the LX220 and PCS1. Check first to see if the pump is capable of
running off of 220 vac. Most pumps can be simply ÒswitchedÓ at a rear panel to run
off 110 or 220 vac. If the pump can run off of 220 vac, we recommend that the pump
be switched and that the power be rewired at the circuit breaker panel from 110 to
220 vac. This simplifies the electrical wiring.
If the pump only runs off of 110 vac, this power can still be used to run the
LX220. However, a separate electrical run will have to be made to the LX220 from
the power panel for 220 vac PCS1 power. This 220 vac is then run from the LX220
[from the power relay] up to the PCS1.
The LX220 power relay controls the PCS1!
