    10. HYDRAULIC CONNECTIONS 10.1. RECOMMENDATIONS FOR HYDRAULIC CONNECTIONS 1. It is recommended that all units are connected to a water supply and return pipe system of the Tickelman Loop type. The Tickelman Loop system is self-balancing and thus only requires manual balancing if a large number of units with different flow and pressure loss characteristics are connected to a single hydraulic loop.

    13. RCL AND µBMS CONTROL MODULES WIRING 13.1. RCL Unscrew the lower screw on the RCL control. Separate the RCL control from its support bracket with the help of a flat bladed screwdriver Lower screw Checking the support bracket : Ensure that the wall surface is completely flat at the point where you wish to install the RCL control, as it is important that the support bracket is not twisted on installation, because any bending could lead to the control not clipping together properly and result in operating difficulties.
