INTRODUCTION
USB series solar water heaters are all-glass evacuated solar domestic water
systems combined with heat pipes. The selective coating in the inner cover of
the evacuated tubes ensures high energy absorption and low heat radiance
losses, which converts solar energy into heat energy and transfers to the heat
pipe by an aluminium fin. The liquid in the heat pipe changes into vapour
which rises to the condenser. The heat conducts the water inside the Header
pipe and the vapour becomes liquid, returning to the base of the heat pipe.
This continuous circulation transfers heat from the heat pipe to the cold
water in the header pipe as long as sun is heating the collectors.
INSTALLATION ORIENTATION
The collector should be mounted facing as close as possible to Due North and
at an angle of 38° to the horizontal

Features
- Very fast start-up even under low solar irradiance, due to the small heat capacity of the heat
pipe combined with good thermal conductivity of the aluminium fin which contacts the inside
of the inner glass tube.
- Utilisation all year round even in cold climates;
- The system will still operate in the event of occasional tube breakages;
- Larger solar water systems consisting of more than one panel can be installed using parallel
and/or series connections;
- Auxiliary electric booster is available.
The most obvious advantages of USB series solar water heater
- Can be installed individually or combined with a traditional system;
- Withstand pressure;
- Can operate with occasional tubes breakage and be replaced easily;
- Works well in low-irradiance day with an electric booster
- ow to avoid cold water and hot water mixing?
If the outflow rate is limited within 8L/min, through a lot of testing such phenomenon is not
obvious.
Transport and operation instruction ：
■ Pac aging and placement Requirements
1. The manifold is with carton pac ing; and there’s protection cap on both ends of the
header pipe.
2, Prevent moisture or water infiltration when placing the cartons.
3, There are "up" signs on the carton pac age of the manifold, so it should be placed
accordingly to avoid internal inversion.
■ Transportation requirements:
1, Ensure it is closely located when pac ing, to avoid the sha ing during transport.
2, Place the bottom on a tray or other things which can load bearing.
3. Prevent infiltration of rain or water.
■ Preparation:
1. After received cartons of goods, the first thing is to chec whether the cartons are
deformed or damped.
2. Open the cartons and chec whether the internal pac aging is intact.
3. Chec the quantity of the components according to the list.
4. Start the installation if everything is ready.

INSTALLATION
Fix the middle holes of the cross supports with M6×25 screws, and then connect the three back
legs together. See the picture below.
Using the M8×16 screws
to connect the upper rail
with the three front legs,
and also fix the upper
rail with the left and
right front legs by u
Splayed Bracing. Using the
M6×45 screws to
connect the front legs
with the back legs. See
the right p
Use M8×16 screws to fix the
front and back legs with the
side support. See the left
picture.

Put the aluminum manifold on the top of the front legs with the link parts. And install the
bottom support on the bottom of the front legs. Put the plastic holder of the heat pipes in the
bottom support. Fasten the baseboard on the front legs with the bolt and nuts M6×45.
Insert the heat pipes:

Solar Collector Connecting
The connecting of the collectors to a collector array can de designed according to the location
and position of the system. Different ways of the connecting reflects the different operation
efficiency. And generally parallel connection and in series connection is suitable for the
collectors as shown with below drawings.
Connection in series: As shown in picture1, put two assembled collectors together, use the
copper connector to connect each solar collector with its 22mm size head. Then connect the
other side of the connector with pipeline. The same kind of connecting shall be carried out
between all the collectors needed.
Parallel connection: First, connect the solar collector outlet and inlet with pipeline with the
copper connector; then, as shown in pic2A and pic2B, the copper bends and three way copper
connectors are used to connect the pipeline together.
The diameter of the pipeline can be Φ12 Φ14 Φ16 and etc, and the pipeline can be some
kind of copper pipe or stainless steel pipe.

Installation on the roof:
The optional reflecting angle for SB series solar collector is 20°, 30° and 40° according to the
locallongitude and latitude.
Procedures:
1. Put the assembled frame on the roof.
2. Move the tile according to the location of the hole on the front support and baseboard for
frame.
3. Move the frame away first, install the mounting nail and expansion bolts into the confirmed
position of the roof.
4. Firm the screw under the hole, and insert the mounting nail through the hole on front legs,
and the expansion bolts into the hole on baseboard according to its exact location.
5.
6.
Spin the screw on the top to adjust to the best location andthen fix it.
Lift cartons of tubes onto roof and fit tubes one at a time.
SMEAR A SMALL AMOUNT OF HEAT PASTE ON EACH HEAT PIPE BULB BEFORE INSTALLING
NOTE: Please wear protective gloves for this process.
Thoroughly wash hands post installation of tubes

Maintenance for the system
Maintenance
-There’s maybe dust and oil existing in water pipe when installing. Please turn out the tap to get
rid of the sundries at the first using.
- For collector surface, please do the cleaning regularly according to the local dusty rate. Raining
can clean the solar water heaterand maintaining a clean surface can be higher collection efficiency.
- For the solar water heaters with reflector, please cleanout the reflector simultaneity.
- Please check the vacuum rate or whether the vacuum tube is crashed regularly. It shows that the
vacuum tube rate is down and must be replaced when the barium- titanium getter get black.
- Generally, it has filter gauze setting at the outlet of tap, the scale and sundries from water pipe
always generate in filter gauze, so please cleanout regularly.
- Solar water heater must be cleanout, check-up , antisepsis every 2 or 3 years. At normal time, user
can disinfect the system by themselves. Such as buying chlorine disinfection of Pharmacy into the
water, soaking for a period of time, and then let it be known, it can play a Sterilization effect (the
use of disinfecting agents, please note the instruction, and using quantity).
Lightning protection procedures：
-Place a lightning rod using metal frame to avoid the thunder, the lightning rod should have a
suitable height.
- The solar collector must be installed in the available area where it can avoid thunder, it’s
important to make the top of the lightning rod on the roof higher than the top of solar collector. At
the same time, the distance between the solar collector and lightning rod should be less than 3
meters.
- Make sure that the solar water tank is connected with the lightning rod or earth-wire.
- Install a power supply lightning arrester to prevent the incursion of lightning electric wave. Don’t
take shower on the days with thundering and raining.
