Installation of the differential bypass valve on manifolds

The differential bypass on manifolds is mounted by following the procedure below:

1) Remove the drain cock (A) from the terminal connector on the upper manifold.

2) Remove the end fitting (B) on the lower manifold.

3) Install the new terminal connector C on the lower manifold.

4) Install the differential bypass and reinstall the drain cock on the new terminal connector of the lower manifold.

Off-centre bypass assembly with fixed setting. 1/2”M threaded connections. Brass body and nuts. Copper pipe. PA check valve
obturator, stainless steel spring, EPDM seals, asbestos-free fibre gaskets. Medium: water and glycol solutions. Maximum
percentage of glycol: 30%. Maximum working pressure: 1

45 psi. Temperature range: 14–230 °F. Fixed setting pressure: 3.6 psi.
