The pressure system for the 2-speed pump or for the circ pump must 5.
discharge water freely into the spa.
If the pressure system for the 2-speed pump includes a diverter valve, or a 6.
diverter jet, there must not be an “off” position that would stop water flow
from the pump or any other position that would throttle or reduce water flow
from the pump.
If the pressure system for the 2-speed pump includes flow adjustable jets 7.
that can be 100% closed, at least 2 non-adjustable jets must be included in
each possible inlet circuit so that a minimum of 20 GPM can flow during low
pump operation with all the jets closed. Any other means of by-passing flow
around the closed jets is acceptable as long as the by-pass means is down
stream from the heater and allows a minimum of 20 GPM to flow through the
heater during low speed operation.
If the pressure system for the 2-speed pump includes flow adjustable 8.
jets that do not close 100%, at least 20 GPM must flow during low speed
operation through each possible inlet circuit with all the jets closed.
If the pressure system for a 2-speed pump or for a circ pump includes a filter, 9.
the filter must be equipped with a by-pass around the cartridge that opens
when the cartridge gets dirty. (Spring tension holding the by-pass valve
closed must be overcome by the pressure of the pump.) This by-pass must
be capable of flowing a minimum of 20 GPM during low pump operation
with the cartridge 100% blocked.
