Safety information, installation and maintenance This document does not contain enough information to install the product/system safely. For full details see the Installation and Maintenance Instructions supplied with the product. Installation notes: The preferred method of installation is to bolt the heat exchanger rigidly to the floor, in a vertical position. We recommend the use of a swan neck on the primary outlet (S2) to ensure the heat exchanger does not dry out - this can otherwise cause problems with debris and can damage the gaskets. Maintenance note: An annual inspection is recommended to check for leaking gaskets and the build up of scale and sludge.

Spare parts Spare plates with integral gaskets are available from Spirax Sarco.

How to order Example: 1 off M6-23 plate heat exchanger having 2" screwed ISO R connections.
