in accordance with water and electrical regulations. Before commencing installation make sure you have all the fittings required. These may include:  Flexi hose with inline shut off valve (not supplied).  25 amp minimum isolator switch (not supplied).  You will also require fittings that are site specific. Installation  Before installation ensure your water and electrical supply are isolated.  Place the INSTA-80 Supreme in the desired fitting location.  The INSTA-80 Supreme can be used with Watersave recommended extras such as Sensor Taps and Showerheads. Plumbing installation  If using cold feed only (Figure 16), connect the cold mains water supply to the water inlet (on right) at the bottom of the INSTA-80 Supreme.  If using hot feed only (Figure 27), connect the existing hot water feed to the water inlet (on right) at the bottom of the INSTA-80 Supreme. o Note! An in line shut off valve must be installed during plumbing of the INSTA-80 Supreme. o Minimum Constant water flow rate of 1.2 litres per minute. o Maximum water pressure of 4 bar.  The Hot water outlet is connected to the hot water supply of the tap. o When connecting to a sensor or push tap. Connect the hot water supply from INSTA-80 Supreme direct to the tap. o When connecting as a shower. Connect the hot water supply from the INSTA-80 Supreme to the shower hose.  For optimum performance, the flow rate should not exceed 3 litres per minute. The flow rate can be regulated using the in-line valve. The flow rate should be regulated to optimise the temperature the end user needs.  Your INSTA-80 Supreme is now fully plumbed.  You can now turn on the cold-water supply and check for leaks.

Operate the taps as normal to get the INSTA-80 Supreme to heat the water. Electrical installation  Note! Ensure that your electricity has been isolated at the mcb first. The INSTA-80 Supreme requires an mcb with a rating of 25 amps. The INSTA- 80 Supreme can be connected to the electrical supply by 25 amp minimum Isolator Switch. Wiring Isolator Switch (Page 8).  Brown/live, blue/neutral, green yellow/earth to be connected to a minimum 25 amp isolator switch. Finalising the electrical install  Switch on electrical current at the mcb.  Turn on the 25 amp isolator switch.  To power up the INSTA-80 Supreme touch the power on/off button once  Electrical installation is now complete.  Electrical Installation must be carried out by a professional. Quick set up guide INSTA-80 Display 1. Turn on the main power supply ⏻, it shows spray on display (Standby mode).

“P”, (Power setting mode) or “H”, (constant temperature setting mode). 3. Press power button ⏻. 4. “P” will then display. Use the ⋀ to bring the setting to 10. 5. Press power button ⏻. 6. “H” will then display. Use the ⋀ or ⋁ to set the temperature to your desired setting. i.e. 55C for kitchens or 43C for washrooms/hairdressers. 7. Once the temperature is set, the display will blink 3 times. It will then revert to the incoming water temperature. 8. When you turn on the tap the water will quickly heat to the temperature you have set. Changing the Kw power setting 1. Setting limited power: On standby mode , press ⋀. In 5 seconds, it will show , you can touch ⋀ one time, it will show , then touch ⋀ again, it will show . Here 55, 45, 35 means 5.5kw, 4.5kw & 3.5kw, which makes the INSTA-80 Supreme work under this setting. 5.5kw recommended. 2. Sleeping mode: When no water is available or water stops suddenly, it will show . 4 mins later, it will turn to standby mode and then once water flows, it will automatically revert back its original setting. The INSTA-80 Supreme has a memory function that allows the unit to keep your previous settings. 3. The flow of the water also determines the temperature. The greater the flow of water the lower the temperature. 4. When being used as an inline heater on the hot water line. The setting we have found most common are H = 55 and P = 10. The kW setting can be either 45 or 55 depending on the flow rate desired by the customer. 55 recommended. When used with a cold water supply the most common settings are H = 55, P = 10 and the kW setting is 55.

ambient water temperatures require lower kW settings. Commissioning Assuming you have installed the INSTA-80 Supreme correctly please commission as follows. How to get hot water flowing from your INSTA-80 Supreme:  Ensure the inline valve from the cold water supply is open.  Ensure the inline valve from the INSTA-80 Supreme hot water supply is turned on fully.  Turn your tap to cold to make sure the water is flowing.  Check the temperature of the incoming cold water.  Turn off the cold water at the tap.  Make sure the isolating valve from the old hot water supply system is turned off.  Make sure the flow rate does not exceed 2.5 litres per minute by adjusting the inline valve between the cold water supply and the INSTA-80 Supreme  Check the power switch to see what power setting the INSTA-80 Supreme is set at. The water should now be at your desired temperature. Please see Diagram 1.0 for flow rate to temperature calculations.  Bring the tap lever back towards the off position and the INSTA-80 Supreme will power off.  In winter the power setting is likely to be P10 and in summer depending on ambient water temperatures may be as low as P6 to achieve maximum flow rates at temperatures of 55°c.  Your tap can be used as a normal mixer tap. Cleaning The INSTA-80 Supreme should be cleaned using only soapy water and a non- abrasive cloth/sponge.
