Mounting instructions The screws and plugs are supplied with the unit. 1. Mark the position of the plugs according to the positional template allowing enough space around the Hotrun to open the Hotrun by removing the top and bottom screws if needed after installation. 2. Mount the unit using 2 screws. 3. Fit the top screw allowing it to stick out approximately 2-3 mm.

Electric connection 1. Australian and New Zealand Standards wiring rules and guidelines must be adhered to. In most situations the installation of a 2-phase supply will be required for the Hotrun 72 and 90, to avoid voltage drop on a single phase supply/connection. 2. It is recommended to provide a dedicated circuit direct from the switchboard to each Hotrun. 3. The Hotrun has to be connected according to the applicable wiring diagram. 4. Check insulation resistance and proper earth continuity.
Initiation Attention: Avoid overheating Fill the unit completely with water before plugging it in or turning on the mains power supply. For that purpose: - Open the tap and wait until the water flows out from the spout without any air bubbles. - Close the tap. - Switch-on the mains supply. - Hotrun is ready to use. Maintenance Due to its advanced design the Hotrun does not need any maintenance. A damp cloth can be used for cleaning the cover. Scouring and dissolving agents are not suitable.
Troubleshooting Remedy - Fix the water pressure problems; remove any flow restrictors in outlets. - Switch the electric power supply off, check that there is no power on any of the terminals. - Seek electrical assistance to check power all the way to the elements. Problem 2 - The water that is coming out of the Hotrun is not warm enough. Cause - The incoming water is very cold (below 12°C) - The total flow is too high. Remedy - A flow restrictor should have been installed.
