3.0 SITE REQUIREMENTS 3.1 3.2 3.3 3.4 3.5 WATER REQUIREMENTS All 7kW heaters must be installed using the supplied 2.5bar pressure reducing valve and have a cold supply minmum pressure of 0.1Mpa (1bar) and a maximum of 0.25Mpa (2.5bar). 9kW and 12kW heaters have an operational pressure range of 0.1Mpa (1bar) to 0.7Mpa (7.0bar). Both inlet and outlet connections are suitable for 15mm diameter copper pipe. The tee piece and expansion relief valve must be situated where shown (see figure3.
ELECTRICAL REQUIREMENTS This appliance must be earthed. The installation, supply cable and circuit protection must conform to the latest BS7671 ‘Requirements for electrical installations’ (IEE Wiring Regulations). 3.8 The PowerPack heater must only be connected to a 230/240V ac supply. 3.9 Before making any electrical connections within the installation, make sure that no terminal is live. If in doubt, SWITCH OFF the whole installation at the consumer unit or switch fuse (where fitted). 3.

4.0 CONNECTING TO SERVICES Multipoint PREPARATION 4.1 Remove the fixing screw which holds the front cover onto the back plate of the PowerPack heater. Carefully remove the cover. 4.2 The unit must be mounted on a flat surface, which covers the full width and length of the back plate. It is important that the wall surface is flat otherwise difficulty may be encountered when fitting the cover. 4.3 DO NOT fit the PowerPack to the wall and tile up to the case.
5.0 COMMISSIONING 5.1 Once installed, the heater will operate automatically when the outlet valve is opened. The valve must be opened fully to obtain the set flow/temperature. Reduced flow at the outlet will result in hotter water being delivered. 5.2 On closing the outlet valve the heating element will automatically shut down provided this tap has been turned off by the user. SETTING FLOW RATE 5.3 To set the flow rate, make sure the water and power are turned off.
6.0 MULTIPLE INSTALLATIONS When larger volumes of water are required than can be provided by one heater, multiple installations can be made by connecting a number of heaters in PARALLEL of the cold feed manifold (See Figure 6). This is the ONLY method that is recommended, provided all water heaters recieve acceptable flow rates (2.5ltr/min recomended). DO NOT plumb these heaters in series. 6.2 To set the heaters in this arrangement use the appropriate procedure as described previously.
7.0 FAULT FINDING YOUR SANTON POWERPACK SHOULD GIVE TROUBLE FREE OPERATION. HOWEVER SHOULD A FAULT OCCUR THE TABLE BELOW SHOULD ALLOW MOST FAULTS TO BE IDENTIFIED. FAULT FINDING SHOULD ONLY BE CARRIED OUT BY A COMPETENT PERSON. SYMPTOM 1. Water too hot 2. Water too cold POSSIBLE CAUSE A. Water flow too low A. Electrical power to the power pack heater is off B.
