Balboa VS500Z Kits include the control system with heater, topside control, Amp 4-prong style equipment cords, light wire, light bulb and light harness . The amp cords plug directly into the circuit board.
These control systems can be wired to 220 Volts or 110 Volts. If wired to 220 Volts, each of the component circuits can be either 220V or 110V.
All 500Z kits operate:
**Most spas don't have a small circulation pump, instead, the main pump runs on low speed to heat and filter the water during set filtration cycles. If you are using a small circulation pump, the flow rate must be at least 25 gallons per minute. In other words, the circulation pump must be similar to a Waterway Iron Might or Aquaflo Circmaster Pump and require a minimum 1.5" size plumbing. Pumps like the Waterway Tiny Might or Laing E10 Circulation Pump are too small and will not work with this control system.
The heater is 5.5 kW (on 220V) / 1.4 kW (on 110V).
The topside control measures 4-3/8" X 1-5/8".
Includes an adapter plate for the topside control. Use if you previously had a larger topside and you need to cover a larger hole. The adapter plate measures 8-1/2" X 3-1/2" and has double-sided sticky tape on the back.
