2.1 Locating the cylinder
Locate the solar cylinder at an appropriate place in the building, while observing the following:
The discharge pipe from the tundish must be installed at a minimum slope of 1:200 and end at a safe and visible point, refer to section 2.9.
The installation surface must be level and able to bear the weight of the full cylinder, refer to table 1.1.
The installation site may not be prone to frost. A frost protection thermostat must be installed if necessary.
There must be sufficient space to install, check and repressurise the expansion vessel.
Floor unevenness should not be greater than the compensation offered by the adjustable feet of the solar cylinder.
2.2 Boiler heating circuit piping
Copper pipes with a minimum diameter of 22mm should be used for the pipes in the reheating circuit between the boiler and the solar cylinder.
Larger pipe diameters may be necessary for relatively large distances between the boiler and the cylinder.
2.3 Motorised 2 port valve
To prevent the Flurocyl cylinder from overheating the 2 port motorised valve supplied must be fitted to the primary flow to the indirect coil.
2.4 Domestic hot water pipework
Connect the hot water outlet to the 22mm hot water connection of the solar cylinder.
Lay a further 22mm pipe to the first
A pipe of 15mm diameter should then be sufficient.
If the pipe is very long or several outlets are supplied, continue with another 22mm pipe.
2.5 Thermostatic mixing valve
A hot water thermostatic mixing valve ensures the hot water from the cylinder is mixed with cold water to a desired maximum temperature between 30°C and 60°C.
Set the thermostatic mixing valve to the desired maximum temperature during the solar system commissioning.
IMPORTANT: Risk of scalding, Set the thermostat mixer to 60°C or below and check the temperature at a hot water tap to ensure effective protection against scalding.
