Casting Procedure - Canalis KR Installation Guide

Follow these instructions for applying the demoulding agent to the moulds.

Step	Action
1		Apply the neoprene seals to both sides of the mould (tongue and groove).
2		Brush the demoulding agent onto the inside of the casting moulds and the seals. Allow the demoulding agent to dry.
3	After ten minutes, remove any excess liquid from the mould and rubber seals.
4		Place the mould on the mechanical connection (Joint block) and secure it with the two C-profiles.
5	Prepare as many casting moulds as possible. The casting mould must overlap the insulation on the two cast resin busbar ends by at least 2 cm.

Follow these instructions to prepare the casting mixture and fill the moulds.

Step	Action
1		Pour the resin (component A) into an empty bucket.
2		Pour the hardener (component B) into the bucket with the resin.
3		Mix using an industrial mixer (rated 750 W or higher) for approximately 30 seconds.
4		Pour the filler material (sand) into the mixture of resin and hardener, and mix until the cast resin mix becomes homogeneous. The mixing time should be approximately 3 minutes.
5		Pour the cast resin mix slowly and steadily up to the upper edge of the installed casting mould. Tap the mould gently with a rubber hammer to allow the bubbles caused when pouring to escape. Do not overfill the casting mould and smooth the surface with a putty knife. Check after 20 mins if the resin has settled and pour again up to the brim. NOTE: Avoid drafts and ambient temperature below 5 °C.
6	Allow the cast resin mix to harden. NOTE: The hardening time is usually around 5 to 14 hours. See table below for the required hardening times at various ambient temperatures.
7	Remove the reusable steel casting mould after hardening.
8	Use a grinding stone to clean the edges and remove any uneven spots on the joint casting. Like the overall system, the joint meets the requirements of IP68.
9	Clean all tools immediately after use and allow them to dry thoroughly. Suitable solvents are methylene chloride or acetone. Follow local regulations when using acetone.

Table with the maximum time before which the mix must be used and the hardening time depending on the ambient temperature

Ambient temperature (°C)	Maximum time before which the mix must be used (Mins)	Hardening time (Hours)
25	20 ... 25	5
15	25 ... 30	7
10	30 ... 35	10
5	35 ... 40	14

After casting a sub-section, perform tests on the electrical connection as described earlier.
