Hot Water Outlet - Dimplex ECS150HP40A-580 Installation And User Instructions Manual

5.2 Hot Water Outlet

The hot water pipe work is to be directly
connected to the hot water outlet connection on
the cylinder, see Figure 1.
5.2.1 Thermostatic Mixing Valve
A thermostatic mixing valve may be required to
limit the outlet temperature. In this case, the
valve should be
manufacturer's instructions, ensuring none of
the safety equipment has been isolated, (i.e.
make sure the connection to the thermostatic
mixing valve is taken after the safety equipment
of the inlet group).
5.2.2 Pipe Insulation
It is recommended to insulate the hot water pipe
work from the cylinder to the outlets, to reduce
the energy requirements for providing hot water.
It is also recommended to insulate all other
exposed pipework, such as the T&P to the
tundish, the coil flow and return and the cold
water inlet pipes.
5.3 Discharge Pipes
Devices
5.3.1 Discharge Pipe D1
 The temperature and pressure relief valve
must be discharged directly or by way of a
manifold via a short length of metal pipe
(D1) into a tundish; and the discharge pipe
must be installed
downward direction and in a frost free
environment. Water may drip from the
discharge pipe of the pressure relief device
and this pipe must be left open to the
atmosphere.
 The diameter of discharge pipe (D1) should
not be less than the nominal outlet size of
the safety device, e.g. temperature relief
valve.
 Where a manifold is used it should be sized
to accept and discharge the total discharge
from all the D1 discharge pipes connected to
it.
 The discharge pipe work from the expansion
relief valve must be installed constantly
falling to an open point of discharge. It is
recommended to
discharge of the temperature and pressure
relief valve.

Note: The T&P valve is pre-sealed and if
moved the seal will be broken, should this
occur, it will need to be resealed with an
appropriate sealant (Dimplex part number
R00836-1).
5.3.2 Discharge Pipe D2

pipework D2 see chapter 4.4.1.
the
5.3.3 Tundish
 The tundish should be vertical, located in the
same space as the unvented hot water
storage system and be fitted as close as
possible to, and lower than, the safety
device, with no more than 600mm of pipe
between the valve outlet and the tundish
(see Figure 2).
 Discharge should be visible at the tundish,
where discharges may not be apparent, e.g.
in dwellings
impaired vision or mobility, consideration
should be given to the installation of a

operated.
Note: To comply with the Water Supply
(Water Fittings) Regulations, the tundish
should incorporate a suitable air gap.

Note: The cylinder must be filled with water
before switching on the immersion heater.
Failure to do so will damage the element
and void any guarantee on the product.
5.4 HP Flow to Buffer Connection
The cylinder buffer flow connection must be
connected to the three port valve, connection B.
See Figure 5.
5.5 Buffer Flow to HP Connection
The cylinder buffer flow to HP connection must
be connected in series with the heat emitter
system/under floor heating.
