Electrical Hook Up; Load Sharing - Dimension One Spas Hot Tub User Manual

Electrical Hook Up

Do not turn on electrical power to your hot tub until told to do so later in this manual.
Warning
Have a licensed electrician run the required 120/240 volt power line to the hot tub installation site. The
power inlet connection is located in the pedestal on the left side of the hot tub, approximately 25" from the
front. This connection is designed to mate with a Carlon 1" conduit body Type LB, Access Fitting E986F or
any 1" female PVC conduit fitting. The manufacturer's label lists the power requirements for your hot tub.
We recommend that only a licensed and bonded electrician do the initial hot tub hook-up.
This unit requires a GFCI (Ground Fault Circuit Interrupter). A "line of sight"
service disconnect must be located where visible from the hot tub, not less than 5 feet from
the hot tub and not to exceed 50 feet from the hot tub. This requirement may be filled with
Warning
the GFCI sub-panel. All supply wire to be rated minimum 90°C.

Load Sharing

Computerized load sharing (available only on Dimension One Spas hot tubs) is used to allow the system to
automatically recognize the temperature differential and the number of jet pumps in use, compare it with the
available power, and adjust the heater to maximize heater output. If you want to be able to run the pumps at
full power and still be able to generate heat at the same time, consider installing the maximum electrical
service available for your spa. If you do not have enough electrical service, your pumps may shut off when heat
is required. Otherwise, heat may be discontinued if you start up the pumps.
