1. Installation
Drain Back reservoir must be installed in position below the lowest point of solar
thermal collectors!
Drain Back reservoir must be installed in position above the floor, in vertical position
standing on its legs
Minimum Height of installing a Drain Back reservoir in combinationwith UniQube
tanks, measured from the lowest point of its legs to the ground is 650mm
!
L ≥ 650mm
L ≥ 650mm
Setup and operation procedure
The following instructions describe a fast and simple way to commissioning the installation
1. Installation of reservoir and pipe connecting
•
Install the reservoir on floor standing table or on wall
• Install all pipes and valves (see page 3 and 4)
2. Filling the drain back system with glycol/water mixture
• Calculate the volume of the fluid that will circulate inside the solar thermal circuit
(see page 5)
3. Pressure increasing of the solar thermal system
• Rising the pressure at 0,5 bar is important to avoid vacuum appearance while operation
(see page 6)
