Martin5k Posted January 15, 2018 Report Share Posted January 15, 2018 I replaced my 15 year old spa pack and now my pumps run slow and overheat. They worked fine with the old spa pack. Spa pack is a balboa vs501z. Quote Link to comment Share on other sites More sharing options...
Dan.The.Spa.Man Posted January 15, 2018 Report Share Posted January 15, 2018 Sounds like the voltage to the pumps could be wrong. Need to check jumpers and instructions and see if the new Pack has different setups for 110v or 220v. Sometimes you need to move wires within the pack. Usually that situation means that the pumps are 220v and only getting 110v, but check first to see what voltage the pumps are supposed to be and double check the instructions. *****I just looked at Balboa 501z wiring diagram and it looks like only the heater or blower can be 220v....so if you have 220v pumps I don't think you can use that Pack unless the pumps are convertible back to 110v. Read the instructions and check voltages to confirm.... Quote Link to comment Share on other sites More sharing options...
Martin5k Posted January 16, 2018 Author Report Share Posted January 16, 2018 That was it and everything works now. The instructions on the pack were incorrect. It has a jumper that you need to add for 240v. The pack says you need to remove it for 240v, and add it for 110v. Thanks for the help.
