3. GENERAL REQUIREMENTS
3.1. The KYROS domestic hot water cylinder MUST be installed by a competent person in accordance
with section G3 of the current Building Regulations.
3.2. Important - It is important that the installer reads and understands these instructions, unpacks
and familiarises themselves with the equipment before commencing the installation. Failure to
observe these installation instructions could invalidate the warranty.
3.3. Water supply – The water supply to the cylinder should be potable water direct from a public
mains water supply with any water treatment equipment functioning correctly.
For optimum performance the unit should be fed via a 15 mm or 22 mm diameter supply pipe direct
from the mains water entry point to the property with supplies a maximum pressure of 0.9 MPa.
The unit can operate with a minimum supply pressure of 0.15 MPa and a flow rate of at least 20
litres per minute, but flow from the outlets will be low if several outlets are used simultaneously.
The cylinder control equipment is factory set to limit the system operating pressure to 0.3 MPa. The
maximum supply pressure into the pressure-reducing valve is 0.9 MPa.
3.4. Taps and fittings - All taps and fittings incorporated in the unvented system should have a
rated operating pressure of 0.7 MPa or above.
3.5. Location – The unit is designed to be vertically wall mounted, indoors, in a frost-free
environment. When choosing a suitable location for the cylinder, consideration should be given
to the routing of the discharge pipe to a convenient point and also the availability of an adequate
power supply for connecting the sheathed heating elements.
The wall onto which the cylinder is mounted should
be of good sound masonry construction capable of
holding the weight of the cylinder when full of water
(see
technical specifications for weights).
The position of the cylinder should be such that easy
access is provided for servicing the controls and
replacing the sheathed heating element should the
need arise.
Pipe runs should be made as short as possible and
lagged to prevent heat loss.
To allow for servicing and repairs the unit must be
mounted at least 540 mm above any surface or object,
so that access can be gained to electric connectors
and the heating elements may be removed (see Fig 1).
The unit should be mounted close to an external wall
so that the discharge pipe D2 can be routed to a safe
visible place.
The tundish should be mounted in a visible location so
that it may easily be inspected. Fig 1 - Minimum margins for servicing and repairs.

Horizontal width between holes 350 mm 350 mm 350 mm 350 mm 350 mm
Height between upper and lower holes 340 mm 573 mm 768 mm 490 mm 670 mm
3.6. Storage and handling – If the cylinder is not being installed immediately, it should remain in its
box with all pipe end protective caps in situ to prevent damage. We recommend that the cylinder be
transported to its installation position with the outer box in place.
3.7. Pipework connections – All pipework connections to the cylinder MUST be made in accordance
with Fig 2.
3.8. Safety – This product is not intended to be used by persons (including children) with reduced
physical, sensory, or mental capacities, or have no experience or knowledge of the product, except if
they are supervised or instructed in the use of the product by a person who is responsible for his or
her safety. Children must be supervised at all times to ensure that they do not play with the product.
4. PLUMBING INSTALLATION
4.1. Connections. Connections MUST be made to the cylinder in accordance with Fig 1, and Fig 2.
A drain cock (not supplied) should be fitted in the position shown in Fig 2 to facilitate draining of
the cylinder.
4.2. Electrolytic fittings – It is a must for the electrolytic fittings to be fitted with the water heater.
If not, the guarantee will be void. Check the T/P Valve to see if it is connected with the electrolytic
fittings . If not, please contact us.
4.3. Cold water supply – For best results, the cylinder should be fed by an uninterrupted supply
pipe into the pressure reducing valve (PRV) with a maximum supply pressure of 0.9 MPa. The
cylinder should not be used on any system with a supply pressure below 0.15 MPa and a flow rate
of less than 20 litres per minute.
4.4. Temperature and pressure relief valve – The temperature and pressure relief valve (T/P Valve)
is supplied. Once the T/P valve is fitted should not be removed from the cylinder or tampered with
in any way. The valve is pre calibrated to lift at 0.7 MPa or 90 degrees centigrade and any attempt to
adjust it will invalidate the warranty and could affect the safety performance of the unit.
The outlet of the T/P valve should be routed in 15 mm copper piping in a downward direction
alongside the water heating unit to the tundish in a frost-free environment. The outlet of the
expansion relief valve must be T’d into this pipe before the tundish so that any water exiting either
valve can be seen draining through the tundish– see figure 2 and 3.
4.5. Pressure reducing valve – The pressure reducing valve should be installed in the cold water
supply to the water heating unit with the arrow pointing in the direction of water flow as shown in
figure 2. This can be connected to a maximum supply pressure of 0.9 MPa.
4.6. Expansion relief valve – This must be installed between the pressure reducing valve and the
water heating unit in accordance with Figure 2. No other valve should be fitted between this valve
and the cylinder. The expansion relief valve contains a non return valve.

08
4.7. Expansion vessel – A suitable expansion vessel with a pre-charge pressure of 0.15 or 0.3 MPa
is available in an optional kit for fitting to all water heating units in the range. The expansion vessel
MUST be fitted to the safety group. The expansion vessel MUST be positioned with the entry point
at the bottom – see Figure 2.
IMPORTANT: Regular checks must be carried out to ensure that the expansion vessel is correctly
pressurised to 0.15 or 0.3 MPa at all times. – see Figure 2.
4.8. Tundish – The tundish must not be positioned above or in close proximity of any electrical
current carrying devices or wiring. The installation should conform with the requirements of item
4.10 below.

4.10. Discharge arrangement.
The tundish must be installed in a position so that it is clearly visible by the user. In addition, the
discharge pipe from the tundish should terminate in a safe place where there is no risk to persons
in the vicinity of the discharge, be of metal, and:
(a) Be at least one pipe size larger than the normal outlet size of the safety device unless its total
equipment hydraulic resistance exceeds that of a straight pipe 9 m long, i.e. discharge pipes
between 9 m and 18 m equivalent resistance length should be at least two sizes larger then the
normal outlet size of the safety device, between 18 m and 27 m at least three sizes larger and so on.
Bends must be taken into account in calculating the flow resistance. Refer to the diagram, tables
and worked example detailed below.
(b) Have a vertical section of pipe at least 300 mm long below the tundish before any elbows or
bends in the pipework.
(c) Be installed with a continuous fall
(d) Have discharges visible at both tundish and the final point of discharge, but where this is not
possible or practically difficult, examples of acceptable discharge arrangements are:
• Ideally below a fixed grating and above the water seal in a trapped gully.
• Downward discharge at low level, (i.e. up to 100 mm above external surfaces such as car
parks, hard standings, grassed areas, etc.) are acceptable providing that where children play or
otherwise come into contact with discharges, a wire cage or similar guard is positioned to prevent
contact whilst maintaining visibility.
• Discharge at high level, e.g. into a metal hopper and metal down pipe with the end of the
discharge pipe clearly visible (tundish visible or not) or onto a roof capable of withstanding high
temperature discharges of water and 3 m from any plastic guttering system that would collect
such discharges (tundish visible).
• Where a single pipe serves a
number of discharges such as in blocks of
flats, the number served should be limited
to not more than six systems so that any
installation discharging can be traced
reasonably easily. The single common
discharge pipe should be at least one
pipe size larger than the largest individual
discharge pipe to be connected. If unvented
hot water storage systems are installed
where discharges from safety devices may
not be apparent (i.e. in dwellings occupied
by blind, or disabled people), consideration
should be given to the installation of an
electrically operated device to warn when
discharge takes place.
Warning Notice – The discharge will
consist of scalding water and steam.
Asphalt, roofing felt and non-metallic
rainwater goods may be damaged by such
discharges. Figure 3 - Typical discharge pipe arrangement.

Worked example
The example below is for a ”diameter temperature relief valve with a discharge pipe (D2) having
4 22 mm elbows and a length of 7 m from the tundish to the point of discharge.
The maximum resistance allowed for a straight length of 22 mm copper discharge pipe (D2) from
a ”diameter temperature relief valve is: 9.0 m.
Subtract the resistance for 4 No 22 mm elbows at 0.8 m each = 3.2 m.
Therefore, the maximum permitted length equates to: 5.8 m.
5.8 m is less than the actual length of 7 m, therefore, calculate the next largest size.
Maximum resistance allowed for a straight length of 28mm pipe (D2) from a ”diameter
temperature relief valve equates to: 18 m.
Subtract the resistance for 4 No 28 mm elbows at 1.0 each = 4 m.
Therefore the maximum permitted length equates to 14 m.
As the actual length is 7 m, a 28 mm diameter copper pipe will be satisfactory.

WARNING: DO NOT SWITCH ON THE ELECTRICITY SUPPLY UNTIL INSTRUCTED TO DO SO IN THE
COMMISSIONING PROCEDURE AND ONCE THE UNIT IS FULL OF WATER.
6. FILLING AND COMMISSIONING
6.1. Check that the expansion vessel charge pressure is 0.15 or 0.3 MPa.
6.2. Check that all water and electric connections are correctly configured.
6.3. Open the main stopcock and fill the unit. Open successive hot taps starting with the tap furthest
from the heater. Leave each tap open for a few moments to allow all air and debris from the system
to exit. Close all of the taps.
6.4. Turn off the mains water supply to the cylinder and drain the system through the drain cock.
6.5. Refill the cylinder with hot taps open and close when water flows freely.
6.6. Manually lift (by rotating the knob) both the expansion relief and the temperature and pressure
relief valves for a short period to remove trapped air from behind the valve seating and to check the
correct function of the discharge arrangement.
6.7. Check all joints for leaks and rectify as necessary.
6.8. With the heater full of water, switch on the electricity supply. Check that the cylinder heats the
water and the thermostat operates. Turn on the hot taps to check that warm water is delivered.
6.9. Check that while the unit is heating up, no water exits from either the expansion relief valve
or the temperature and pressure relief valve. If water does exit through the valves check the
expansion vessel pressure and installation.
6.10. Increase the temperature to maximum and allow the unit to heat and the temperature to stabilise.
Check that no water discharges from the valves. Turn on the hot taps to drain the heater of hot water.
Set the thermostat to the required temperature and allow the heater to reheat ready for use.
7. SERVICING AND MAINTENANCE
7.1. Servicing and maintenance must only be carried out by a competent unvented hot water heater
installer or by Rointe authorised personnel.
7.2. Before any work whatsoever is carried out on the installation, it MUST first be isolated from
the mains electricity supply.
7.3. Only use spare parts authorised by Rointe. The use of other parts will invalidate the warranty.
7.4. Drain the cylinder – When draining the cylinder, always switch off the water heater. Turn off
the water supply at the stopcock (see Fig 2). Connect a hosepipe to the drain cock (see Fig 2) and
route it to a convenient gully. Open the drain cock and all hot taps that are served by the cylinder.
The cylinder may take several minutes to empty completely.
7.5. The magnesium anode must be checked at least once a year, and must be replaced if worn
or defective.

13
7.6. Remove the cartridge from the pressure reducing valve. Check the strainer and if necessary
remove any debris from in front of it. Replace the cartridge.
7.7. Check the charge pressure in the expansion vessel and top up as necessary. The charge
pressure should be 0.15 or 0.3 MPa.
7.8. Close the drain cock, disconnect the hose, refit the heating element and close all hot water
taps before reopening the stopcock. Allow the cylinder time to fill whilst checking for any leaks.
Release any air from the system by opening each hot water tap individually, starting with the one
furthest from the cylinder.
7.9. Manually lift the expansion relief and temperature and pressure relief valve one at a time,
every 12 months (more frequently in hard water areas) to prevent debris from building up behind
the valve seat. Whilst carrying out this operation, check that the discharge to waste is unobstructed.
Check that each valve seals correctly when released. As the valves are pre-calibrated, they require
no further maintenance.
7.10. Finally, when the heater is full of water switch on the mains electricity supply to the water
heater. As the system heats up, check again for any leaks and rectify as necessary.
7.11. In the event of the manual reset cut-out operating, isolate the heater from the mains supply,
investigate and identify the cause of the operation of this cut-out, rectify the fault before manually resetting
the cut-out via the reset button on the cut-out. Finally switch the mains electricity supply back on.

12. RECOMMENDATIONS
12.1. When a hot tap is turned on there may be a short surge of water, this is quite normal with
unvented systems and does not mean there is a fault.
12.2. When you first fill a basin the water may sometimes appear milky. This is due to very tiny air
bubbles in the water which will clear very quickly.
12.3. If water is seen dripping through the tundish at any time switch off the electricity supply
immediately and call the installer or the Rointe customer service department on the number listed
at the end of this guide.
