Assembly
The water heater is only designed for upright installa-
tion.
Position the water heater on a m base that can bear
its weight, preferably on a concrete r or founda-
tion. Use the water heater’s adjustable feet to obtain
a horizontal and stable set-up.
Pipes must be routed from the safety valve to a suit-
able drain.
The water heater’s installation area should always
have a temperature of at least 10 °C and max 30 °C.

General
Pipe installation must be carried out in accordance with
current norms and directives.
Internal support bushes should be d when a plastic
pipe or annealed copper pipe is used. The water heater
must be d with the requisite valves, such as a safety
valve, valve, non-return valve, and vacuum valve.
An w pipe must be routed from the safety valve
to a suitable drain. The size of the w pipe must be
the same as on the safety valve. Route the w pipe
from the safety valve enclosed along its entire length and
ensure that it is frost proof. The outlet of the
pipe should be visible and clearly away from any electrical
components.
w water from the safety valves goes via non-
pressurised collecting pipes to a drain so that hot water
splashes cannot cause injury. These non-pressurised col-
lecting pipes shall not be used for anything else. A dis-
charge pipe from the tundish connected to the expansion
relief valve (safety valve) shall also be connected to a drain
in the same way.
Please note that the connection of the T&P-valve should
not be used for any other purpose.
Valves may not be positioned between the expansion
valve and the vessel.
Discharge pipes from tundishes shall have av vertical
section of pipe at least 300 mm long, before any elbows
or bends in the pipework (see following picture).

necessary.

Cold and hot water
Connecting cold and hot water
There must be a mixing valve if the temperature can ex-
ceed 60 °C.
The e hose to the expansion vessel can be installed
in the plugged connection on the safety valve.
Connecting hot water circulation
Titanium MegaCoil 200 & 300 hav e a connection that allows
hot water circulation.
To reduce the risk of bacterial growth in systems with
hot water circulation, the temperature of the circulating
water should not fall below 50 °C. There should not be
any non-circulatory hot water pipes. Adjust the hot water
system so that the temperature does not fall below 50°C
at the ends of the system.
Docking
Titanium MegaCoil 200 & 300 can be connected in several
ways, one of which is shown here.
Further option information is available at www.nibe.co.uk
and in the respective assembly instructions for the heat
pumps used.

NOTE
Electrical installation and service must be carried out under the supervision
Sensors (See page 10)
The Titanium Megacoil can accommodate up to two hot water sensors, one for
SMO Controller display and one to control start and stop of heat pump.
Chapter 5 | Electrical installation 15
5 Electrical installation
The display sensor is positioned in the submerged tube for the display sensor (UA1)
and the control sensor in the submerged tube for control sensor (UA2). In cases where
it is only possible to connect one sensor, use the submerged tube for control sensor (UA2).
Titanium Megacoil/Megacoil-Solar can also be supplemented with a solar sensor.
This is placed in the submerged tube for solar sensor (UA3).
Use the sensors provided with the heat pump/control module. When no heat sensors
have been provided, these must be ordered from the manufacturer of the heatpump/
control module.

NOTE
At the time of commissioning, complete all rel-
evant sections of the Benchmark Checklist loc-
ated at the back of this document.
Completion of the Benchmark Checklist is a
condition of warranty. For full terms and condi-
tions of warranty, please see our website
www.nibe.co.uk.
Filling and venting
Filling the hot water heater
1. Open a hot water tap in the house. (XL4)
2. Fill the hot water heater through the cold water
connection (XL3).
3. When the water that comes out of the hot water tap
is no longer mixed with air, the water heater is full.
and the tap can
be closed.
Filling and venting the charge coil
Filling and venting
1. Open the g valve (external, not included with the
product). Fill the coil in the hot water heater and the
rest of the climate system with water.
2. Vent the coil of the climate system via
the relevant venting valves.
3. Keep topping up and venting until all air has been
removed and the pressure is correct.

After servicing, complete the relevant Service
Interval Record section of the Benchmark
Checklist located at the back of this document.
Completion of the Service Interval Record is a
condition of warranty. For full terms and condi-
tions of warranty, please see our website
www.nibe.co.uk.
NOTE
Any servicing must be carried out byacompet-
ent person.
Maintenance
General inspection
Check the following:
1. Condition of casing.
2. Electrical connections.
3. Pipe connections.
Correct any fault before continuing.
Hot water heater
Check the following:
1. Expansion relief valve.
2. T&P valve.
3. Discharge pipe.
4. Expansion vessel.
Correct any fault before continuing.
Service actions
Safety valves
The function of the safety valves must be checked regu-
larly. Perform checks as follows:
1. Open the valve by turning the knob anti-clockwise
carefully.
2. Check that water ows through the valve.
3. Close the valve by releasing it. I t does not close
automatically when released, turn it anti-clockwise
slightly.
NOTE
Do not remove or adjust any components that
arepartofthispressurisedwaterheater.Contact
your installer!
NOTE
If this pressurised water heater developsafault,
e.g.aow of hot water from the overow pipe,
turn the heat pump oand contact your in-
staller.
Cleaning
Inspect and clean the water heater by using a suitable
instrumentsuchasanendoscope.Thehotwaterconnec-
tion (XL4) must be removed to facilitate access.
Emptying
The water heater is emptied through the drain cock (with
hose connection) in the cold water connection (XL3).
Drain the charge coil through the siphon (with hose) on
the docking connection, return to heat pump (XL9).
Drain the solar coil through the siphon (with hose) on
the connection, return to solar heating system (XL14).
