Domestic hot water tank for Daikin Altherma Monobloc (R32)
Typical workflow
Installation typically consists of the following stages:
1. Siting the domestic hot water tank.
2. Connecting the water piping.
3. Connecting the electrical wiring.
4. Finishing the domestic hot water tank installation.
4.2 Siting the domestic hot water tank
4.2.1 Installing the domestic hot water tank
1. Check if all domestic hot water tank accessories are enclosed
2. Place the domestic hot water tank on a level surface. Make sure
the tank is mounted level.
4.3 Connecting the water piping
4.3.1 About connecting the water piping
Typical workflow
Connecting the water piping typically consists of the following stages:
1. Connecting the water piping.
2. Filling the domestic hot water tank
3. Insulating the water piping.
4.3.2 Connect the water piping
Position the inlet control group so that the discharge from both safety valves
can be joined together via a 15mm end feed Tee. Connect the tundish and
route the discharge pipe. The discharge pipe work must be routed in
accordance with Part G3 of schedule 1 of the Building Regulations. The
information that follows is not exhaustive and if you are in doubt you should
seek advice. The two safety valves will only discharge water under fault
conditions. When operating normally water will not be discharged. 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,
not more than 600mm of pipe between the valve outlet and the tundish.
Any discharge should be visible at the tundish. The tundish should be located
such that and discharge is visible. In addition, where discharges from safety
devices may not be apparent, i.e. people with impaired vision or mobility,
consideration should be given to the installation of a suitable safety device to
warn when discharge takes place i.e. electronically operated.
WARNING
The discharge pipes from the pressure relief valves MUST terminal
in a safe and visible position without forming any risk to persons in
the vicinity.
WARNING
•
Discharge piping, tundish, drain valves, etc. must be positioned
away from any electrical components.
•
The discharge pipe away from the tundish must terminate in a
safe, visible position without forming any risk to persons in the
vicinity.
WARNING
•
Do NOT install any valves between the domestic hot water tank
and relief valves/expansion vessel
•
Do NOT install shut - off valves between expansion relief valve and
the domestic hot water tank
NOTICE
•
Where the secondary return circuits are used, an additional
expansion vessel may be required.
•
All pipework and fittings must be flushed free of flux and debris
prior to installing the domestic hot water tank kit. Failure to do
this may cause irreparable damage to the tank kit controls. Flush
the system by opening the hot water tap.
•
The tundish pipework must be a 22 mm metal pipe with a
minimal vertical length of 300 mm below the tundish before any
elbows or bends in the pipework. All pipework must have a
continuous fall of 1 in 200 thereafter. Maximum permitted
(equivalent) length of 22 mm pipework is 9m. Each bend or
elbow is equivalent to 0.8m of pipework.
Sizing of copper discharge pipe D2 for common temperature relief valve outlet
sizes:
(a) The maximum allowed resistance is expressed as a length of straight
pipe (i.e. no elbows or bends).
If in any doubt, refer to Building Regulations G3.
Before installation
Locate the domestic hot water tank in a suitable to facilitate the installation of
water supply, discharge fittings and pipework. It is therefore recommended to
first read through this whole procedure.
In the box all the needed components for G3 - compliance have been installed
from the factory.

NOTICE
The temperature and pressure valve is factory installed on the tank.
Do NOT remove the temperature and pressure valve.
2. Connect the hot water outlet from the tank to the hot water means of the
house
3. Connect a metal discharge pipe from the tundish. Refer to “ Discharge pipe
requirements ” in this chapter. All pipework must have a continuous fall and
be fitted conforming to the requirements of the building regulations G3.
4. The expansion vessel must be connected to the valve block: Remove the
plug (¾—female) (see illustration below) and use appropriate pipework to
connect the expansion vessel in a vertical position and fully supported for
it
