Installation Requirements
The INSTA-80 should be installed by a suitably qualified professional and 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 in the desired fitting location.
The INSTA-80 can be used with Watersave recommended extras such as
Push Taps, Sensor Taps and Showerheads.
Plumbing installation is as follows: See Diagram Page 7.
The cold mains water supply is connected to the water inlet at the bottom
of the INSTA-80.
oNote! An in line shut off valve must be installed during
plumbing of the INSTA-80.
oMinimum Constant water pressure of 0.5 bar.
oMaximum water pressure of 4 bar.
The Hot water outlet is connected to the hot water supply to the tap. An
isolation valve must be connected to the current hot water supply. You can
then isolate the old supply and turn on the new supply from your
INSTA-80. This allows the end user to avail of the hot water in their tank
during the winter period by isolating the supply from the INSTA-80 and
turning on the supply from their existing heating supply.

11
When connecting to a sensor or push tap. Connect the hot water supply
from INSTA-80 direct to the tap.
When connecting as a shower. Connect the hot water supply from the
INSTA-80 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 is now fully plumbed.
You can now turn on the cold water supply and check for leaks.
Move the lever on your tap to the cold position (right) to allow water to
flow. Allow a flow rate of 2.25 litres per minute on the hottest position if
55°c is the required temperature.
The INSTA-80 may be fitted with a sensor tap or push tap. Operate the taps
as normal to get the INSTA-80 to heat the water.
Electrical installation is as follows:
Note! Ensure that your electricity has been isolated at the mcb first. The
INSTA-80 requires a mcb with a rating of 25 amps. The INSTA-80 can be
connected to the electrical supply by 25 amp minimum Isolator Switch.
Wiring Isolator Switch: See diagram page 6.
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 touch the power on/off button once
Choose the temperature of the water you wish to achieve IE: 55°c by
touching the up ˄/ down arrows ˅
Check the temperature of the incoming water supply.
Touch both the arrows to move to the desired power setting. This will
range from P1 to P10.
Turn on the tap to the hottest position. The digital read out will tell you the
temperature of the water. Adjust the power setting up or down to increase
or decrease the temperature.

12
Adjusting the water flow will also increase or decrease the water
temperature.
NOTE! The temperature can be adjusted by either the power button or the
water flow rate.
To power off the INSTA-80 touch the power off button twice.
Electrical installation is now complete.
Electrical Installation must be carried out by a professional.
Commissioning
Assuming you have installed the INSTA-80 correctly please commission as follows.
How to get hot water flowing from your INSTA-80:
Ensure the inline valve from the cold water supply is open.
Ensure the inline valve from the INSTA-80n 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
Check the power switch to see what power setting the INSTA-80 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 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.
How to get cold water flowing from your INSTA-80:
Turn on your cold tap as normal.
