The time varies between prep methods:
- Method A: ≈ 24 hours
- Method B: ≈ 3 hours
- Method C: ≈ 24 hours
In the user guide we recommend Method A, although all methods work. Choose the method that works best with your schedule and available resources.
If you store the PCM panels in your freezer they will be available to use whenever you need them. Shake the panels to see if they are solid. If they are slushy your freezer is not cold enough. If the panels are slushy they will still work, but the hold times will be decreased.
Prep Method A:
- Store panels in an ultra-low freezer* so PCM is solid (i.e. 48 hrs. @ -30°C).
- Before assembly, shake panels to verify PCM is solid. If liquid is heard, restart at step 2a to ensure longest hold time. Using liquid panels, or panels with a solid/liquid combination, deceases hold time
Store in coldest area of freezer; space out panels for good airflow; if stacking, insert a spacer (pencil, tongue depressor, etc.) in between each.
