HydroNex DHX Panel Sizes: 1-1/4" Trunk; 1-1/4" Zone DHX panels use injection mixing to modulate the supply fluid temperature to the radiant or snowmelt zone. A heat exchanger is used to isolate system fluid from the zone fluid. Both the injection bridge and the zone supply piping is 1-1/4". A Tekmar 361 can be selected for heating applications or a Tekmar 665 may be selected for snowmelt applications. Both have the ability to operate with reset (injection) or set point temperature control.
Installation Make sure an electrical outlet is within 3 feet of where the D-Series panel will mount. If there are no outlets, one will need to be added. Install and level Z-Bracket with 1/4” x 2-1/2” lag screw to studs. Make sure the Z-Bracket is the correct size for the given D-Series panel. Incorrect Z-Brackets may interfere with cover placement. Hang the D-Series panel on the Z-Bracket. Lag screws should be added to the bottom of the panel, further securing the panel to the wall. Hang cover from top down. To purge a DHX panel make sure all necessary isolation valves are closed and all purge valves are open. Proceed until all zones are filled and purged. Open all purge ball valves and cap the drain. Make sure all isolation ball valves are open for normal operation. Both sides of the heat exchanger will require seperate purging. Refer to the installation manual for further details.
Features – Wall mounted white powder coated back panel and cover. – Easy access to all components. – Pre-wired circulators and controls. – Simple CAT 5 jump wiring to connect panels. – Single union connection between panels. – Integrated leveling system. – Z-Bracket for simplified mounting.
