This is an excerpt from the Spa Pool manual.
For some spa owners, the prospect of leaving their beloved spa unattended during a hibernation phase might be daunting, especially if there's no reliable support from family, friends, or neighbors to assist in periodic maintenance. If you can’t guarantee you or someone can regularly maintain the spa during the hibernation period, this guide will walk you through the essential steps for safeguarding your spa during hibernation while it’s left unattended.
1. See Previous Steps
Perform steps 1 and 2 from Leaving the Spa Pool Short Term before moving on.
2. Turn OFF Spa Pool
Completely turn off the spa pool at your isolation switch or mains board.
3. Drain the Water
Drain the water out of the spa pool via the external drain valve.
4. Drain pipes via Barrel Unions
Open up the cabinets surrounding the spa pool and locate the barrel unions at the controller unit / heater and the pumps. Loosen (strop wrench may be required) the barrel unions either side of the component to drain excess water from the surrounding pipes. Put down a towel if required, to soak up water. Tighten the unions back up once finished.
5. Blowout Pipes (recommended if switching off for 6+ months)
Climb inside the spa pool with a ‘Wet-Vac’. Remove the jet pieces and place the vacuum nozzle into the jet body to suck water directly out of the pipe. Not every jet piece needs to be attended to, aim for 3-4 per seat. Other pipes to suck water from are the internal drain valve and the circulation jet mounted on the side of the spa pool acrylic (usually near the topside control panel).
6. Wash Jets
Remove the jets from the spa and rinse them with fresh water. Then wipe the jets clean and dry before putting them back into the spa.
7. Wipe Down Spa Pool
Remove any excess build up of water from inside the spa pool and wipe the acrylic shell down completely with a microfibre cloth and mild all-purpose antibacterial Spray.
8. Secure Cover
Place the spa pool cover on securely and lock with clips. Cover entire spa pool with a tarp or ‘spa pool winter cover’ for the best long-term protection.
