5.0 Installing the MonoSolar
5.1 Requirements
See also sections 1.2.5 & 1.2.6. If the distance between the bottom of the MonoSolar
and the top of the panel is greater than 6.0 metres, then a drain back vessel must be
fitted. See Fig 5.3 & 5.4. Alternatively a second pump can be fitted, increasing the
max. distance to 11.0m.
The following items are needed for the installation:-
8mm OD copper pipe (Solar panel flow)
10mm OD copper pipe (Solar panel return)
15mm OD copper pipe (cold water inlet and hot water outlet)
pipe insulation (see section 5.3)
sensor cable (see section 5.6)
drain cock type A and other items (see section 10)
NOTE -Expansion
The MonoSolar has space in the tank to allow for expansion and contraction and
hence a separate expansion vessel is not needed.
5.2 Assembly
5.2.1 The parts supplied are shown in Figure 5.1 below. See also Figure 5.2.
Note The sensor may be supplied with the solar panel.
Figure 5.1
5.2.2 Insert outlet bend using PTFE tape. Wind four times around the thread of the
bend.
5.2.3 Remove one of the side entry plugs (preferably the one nearest the panel) and
fit the outlet bend to rest in the vertical plane.
5.2.4 Fit pump and pipe work.
5.2.5 Fit a drain cock type A on the other side.
5.2.6 Unscrew the two screws on the side of the lid and remove the lid.
5.2.7 Remove the red cover of the 15mm pipe to the top of the cylinder and connect
the T-piece. Plug the connection using the plug removed from the side of the
tank.
5.2.8 Connect the 3 bar pressure relief valve with PTFE tape to the riser pipe and fit a
22mm pipe to the outside via a tundish.
PLEASE NOTE!
It is possible that ‘dead water’ will come out of the system when you remove the plug.
This water can cause stains on your carpet!
