How Long Can You Leave Your MSpa in Standby Mode?

Dave's comment: I've not yet found the limit. The longest I've left one of my MSpas has been 6 weeks.

Quick Method

When I'm sure I won't be back at my MSpa within a week or two, if I'm in a hurry I simply check the water balance to ensure it's ideal and put a new or near new filter cartridge on the inlet grill.

Thorough Method for Extended Periods

If I have time before leaving my MSpa for an indefinite period, I do the following:

1. Clean the valves: With the MSpa filter turned off and the cartridge removed, remove the inlet and outlet valves. Open the valves by undoing the central screw and ensure the valves are clean.
   PLEASE NOTE: BE SURE NOT TO LOOSEN THE GRILLS WITH THE SUPPLIED GRILL WRENCH FOR UNITS WITH A SMART CONTROL (CONTROL UNIT INSIDE THE SPA WALL). THIS CAN ALLOW WATER TO ENTER THE CONTROL UNIT AND CAUSE DAMAGE.
2. Clean the pipes: Wipe the pipes between the MSpa pool and control unit to ensure there is no residue or debris between the pool and the control unit.
3. Flush the control unit (Frame Series only): For Frame Series MSpa owners (Mono, Oslo, Tuscany and Tribeca), if you have time, also consider using the caps to save the water in your MSpa. Remove the control unit from the MSpa pool and give it a good flush with a hose running the water through the inlet pipe.
4. Install fresh filter: After attaching the control unit, reassembling the inlet and outlet valves, put a new or near new clean filter cartridge on the inlet valve.
5. Balance the water: Ensure your MSpa water is balanced, with the pH within the ideal range 7.2–7.8. Add chemicals as normal to obtain the right balances of pH, alkalinity etc.
6. Add slow-release chlorine: Use a slow-release chemical dispenser. Close the dispenser up completely and add an appropriate amount of spa chlorine (or bromine) tablets to the dispenser and place that in your MSpa. I'll use up to three if I'm not confident I'll be returning within 3 weeks but for a shorter period it might be only one or two tablets.

Ongoing Maintenance

If your MSpa is at a location where you or someone else can still easily access the spa, consider testing the water again after two or three weeks and adding chemicals if required.

Dave's comment: In my 6 week scenario above, all that we needed to do when we returned to our MSpa was to add a normal dose of chlorine.
