- Place panels in a freezer until all PCM turns solid (i.e. 2 hrs. @ -15°C). Shake to verify.
- Transfer panels into a fridge at least 3 hours before use. Panels may be stored in the fridge until needed for assembly, or the PCM melts.*
- 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, decreases hold time.
