This is for my old Sylvan pool yours likely differs.
- Balance and 2x Shock Pool (and Algaecide if it isn’t in the shock)
- Lower water below skimmer and inlets
- Pressurize with compressor at pump (25psi). 1/4″ compressor fitting into pump drain opening.
- Close valve on suction side
- Clear pressure side (after pump side)
- Cap shallow end inlet (doesn’t really match which)
- Once one deep end inlet blows only air uncap the shallow end and cap the deepend
- Once shallow end inlet only blows air detach compressor and cap it.
- Now the pressure side is capped shut
- To clear the inlet it helps to cover the inlet with the cap for a few seconds to let pressure build and remove to blow out water. Repeat until only air comes out.
- Clear deep end suction side
- Set the suction side valve to close the deep end
- Attach compressor
- Once skimmer blows air in deep end cap it
- When main drain bubbles turn valve to shallow end
- Deep end main drain is air locked
- Clear shallow end suction side (before pump)
- Once skimmer blows air cap it
- When main drain bubbles turn valve to shallow end and detach compressor at the same time
- Deep end main drain is air locked
- Close suction side valve and open filter side valve
- Cover pool
- Drain pump
- Remove compressor fitting and remaining drain plug
- Store plugs in pump basket
- Drain and clean filter
- Remove DE filter panels and clean
- Clean DE left in bottom
- Store regulator in a place it won’t freeze
- Leave relief vale open
- Drain heater (leave connections loose)
