Easy to install
X-FLOW Kit is easy to install and connects directly to your pool's circulation pump. The system is equipped
with a by-pass unit which allows adjustment of the flow rate as well as turning the system on and off.
Unpack your X-FLOW kit and check that everything is included according to the contents list "included in the
box" on page 3 of these instructions. NOTE: Do not use any sharp tools when opening the solar collectors as
this could cause damage.
Assembling the By-pass unit (fig 1)
1. Assemble the by-pass unit (see fig 1). Use the Teflon tape to ensure that all connections are tight.
Assembling the Pressure Regulator (fig 2)
1. Assemble the two hose connectors on each side of the pressure regulator. Use the Teflon tape to ensure that
all connections are tight.
Assembling the solar collectors (fig 3, fig 5)
1. Place the solar collectors in a wind sheltered location facing the sun. The solar collectors can be installed in
any location of your choice, but make sure that there are no fixtures that can cast a shadow over the collectors
(see fig 5 for assembly options).
2. Attach the solar collectors' inlet and outlet, use 12 mm (1/2") hose and the two T-shaped connectors. Attach
the pressure regulator to the hose leading TO the solar collectors (NOTE! ensure the correct direction ac-
cording to the arrow on the pressure regulator), and as close to the T-shaped connector as possible (see fig 3).
Attach the hoses to the by-pass unit (see fig 3).
3. Ensure that the power to the pump is off (unplug the cable).
4. Cut the returning hose from the circulation pump into two pieces.
5. Attach the by-pass unit to the circulation pump's divided returning hoses (for 38 mm use the supplied redu-
cer). Use hose brackets to secure the returning hoses.
6. Adjust the pressure (see below).
Adjusting the pressure
1. Open the control valve completely.
2. Backwash your sand filter so that it is completely clean prior to the adjustment process. NOTE! This is very
important since faulty tuning can lead to reduced cleaning capacity.
3. Wait a couple of minutes until the measuring function on the manometer is stable.
4. Slowly close the valve until the pressure according to the manometer has increased by 0.2-0.3 bar.
5. Compensate for any difference in height between the manometer and the solar collectors. If the solar collec-
tors are placed ABOVE the manometer then the PRESSURE NEEDS TO BE INCREASED with +0.1 bar/meter.
If the solar collectors are placed BENEATH the manometer then the MAXIMUM ALLOWED PRESSURE should
instead be reduced by -0.1 bar/meter.
Example: solar collectors ABOVE the manometer: The solar collectors are installed on a roof that lies 2.5 me-
ters higher then the manometer. Once the pressure reading is stable (see point 3 above) the manometer shows
0.3 bar. The control valve should then be closed slowly until the pressure reading on the manometer has in-
creased by 0.2-0.3 bar (the manometer reading now shows 0.5-0.6 bar). A final compensation for the difference
in height up to the roof is required with an additional 0.25 bar and the manometer now reads 0.75-0.85 bar.
Example: solar collectors BENEATH the manometer: The solar collectors are placed in a hollow that lies 2
meters below the manometer. Once the pressure reading is stable (see point 3 above) the manometer reads 0.3
bar. After that the control valve should be slowly closed until the pressure on the manometer has increased by
0.2-0.3 bar (the manometer now reads 0.5-0.6 bar). No compensation for the difference in height is required,
however the maximum allowed pressure is reduced from 1.0 to 0.8 bar. The installation is acceptable when the
manometer reads 0.5-0.6 bar.
6. Note that the maximum pressure in the solar collectors may never exceed 1.0 bar. If for example the solar
collectors are placed on a 2.5 meter high roof then the maximum allowed pressure on the manometer is sub-
sequently 1.25 bar. If the solar collectors are instead placed 1 meter below the manometer then the maximum
allowed pressure on the manometer is 0.9 bar.
