Jacuzzi Z100 Owner's Manual page 19

The Model Z100 Portable Whirlpool spa requires a separate 115 VAC 20 AMP electrical supply. If the wiring for the circuit
in which your spa is connected is not sized properly for 20 AMP, or if the outlet used is too distant for the main service panel,
there may be a considerable voltage drop. Such a voltage drop would not only cause the unit to malfunction, but it may also
cause permanent damage to the spa's electrical system.
Before operation your spa, therefore, we recommend that you test the spa's intended electrical supply circuit for sufficient
voltage. To do this, you will need an AC voltage meter and a small electric appliance rated at 1200 (minimum)–1600
(maximum) watts. A hair dryer or toaster will do. Plug the appliance into one receptacle and turn it on; take a voltage meter
reading from the adjacent receptacle. If the voltage is measured at 115 VAC (a voltage drop of 5%, or if there is less than
the 105V minimum operating voltage at the receptacle, the electrical supply is insufficient. The minimum voltage must be
maintained during spa operation.
If your test reveals insufficient electrical supply, several solutions are possible. First, you could have your electrical supply
upgraded and provide a dedicated, properly wired circuit with 20 AMP capability to be used for the spa only. Second, you
can install a transformer which would boost your existing power supply. We recommend that you seek the advice and service
of a qualified electrician who can determine your particular electrical needs for installation of your spa.
