Power

110V, 20A dedicated outlet

Base

A level, solid base: a concrete pad, pavers, or a framed deck checked for the load.

Permits

Electrical work usually needs a permit, and some cities regulate backyard structures. Check with yours first.

Install notes

Most residential plunges and chillers here run on a standard 110 to 120V outlet. Use a GFCI protected receptacle, avoid extension cords, and give the chiller the ventilation clearance the maker lists so it can shed heat.

A filled plunge is heavy, often 800 to 1,500 pounds. Indoors, put it on a slab or a floor an engineer has checked; outdoors, use a level pad and plan drainage for water changes.

The maker lists a 110V, 20 amp dedicated outlet. That usually means a new circuit, so plan for an electrician.

Not included. Plan for these.
