If the pressure system for a 2-speed pump or for a circ pump includes branch 10.
circulation lines such as circuits intended to operate ozone injection systems,
these branch circulation lines must be connected downstream from the
heater.
Avoid inter-connection of the plumbing circuits for the 2-speed pump or for 11.
the circ pump with other pumps in the spa plumbing system for the purpose
of freeze protection. The Revolution control system will provide freeze
protection. There is also provision for remote sensing freeze protection
if required.
Position inlets and jets in the spa so that they do not direct water flow 12.
towards suction fittings or skimmers. This will avoid a “thermal short circuit”
and prevent excessive heater and pump cycling.
If service valves are a part of the circulation system for the 2-speed pump 13.
or for the circ pump, be sure to use valves that incorporate a means of
“locking” in the open position.
If the 2-speed pump or the circ pump is replaced in the field by service 14.
personnel, the replacement used must equal or exceed the hydraulic
specifications of the original pump.
To assure adequate performance, the spa plumbing must be 11⁄2” minimum. 15.
The use of 2” is highly recommended. Either schedule 40 or flexible PVC
pipe is acceptable.
It is recommended that 16. shut-off valves be installed in the suction and
discharge lines.
