+**Suitable PPE should be worn when using the two-part Epoxy potting compound.
 Warm the compound in the water bath (this should be set to 40 degrees), this takes approximately 10 minutes for the bath to come up to temperature and 5 minutes to warm a bag of compound. Do not warm above this temperature as it will greatly reduce the pot life of the compound.
 Once warm, work the black potting BEFORE removing the clip and rail – this will help remove any lumps caused by the fillers that have settled over time. Then, place back into the bath for 2 minutes.

+To avoid air gaps under the PCB and around the wiring, the sender must be at a slight angle – a cotton bud under one side is enough.
 The compound can then be slowly poured into the lower side, as this allows the potting to fill up level with the board and prevents air pockets.
 Once all air has been removed under the board, you should see a ring of potting all around the outside of the PCB.
