Hot and cold water supply requirements:
3/4” supply lines with on/off valves with 3/4” NPT female threads. We recommend 3/4”
ball valve with 3/4” NPT female ports. (Valves supplied by others.) See figure 8 for
recommended locations.
For optimum performance, dynamic pressures should be nominally equal between hot and
cold supplies.
Maximum static supply pressure: 145 PSI.
Maximum dynamic/maintained supply pressure: 81 PSI.
Maximum supply Hot water temperature: Consult local requirements for maximum
allowed supply temperatures. (Not recommended over 120
o
F)
Electrical requirements:
The Cascade tub Aqua-Air (with reservoir) is rated 7.25 amps at 120 Volts AC.
A 15 amp GFCI circuit is required.
(The optional Cascade reservoir, is rated at .75 amp and is connected to the tub’s electrical
box via hard wiring.)
Unpacking the tub:
1.
Remove the tub from the shipping crate.
2.
Locate and save the installation parts.
3.
Remove all access doors and place them where they will not be damaged during the
installation process.
