Product Description:
The SP Blue Solo 80 and SP Blue Solo 80 E are solar domestic hot water systems which use the sun’s
radiation to heat potable water for domestic use. These systems are thermosiphon systems which
means that they do not require the use of a pump to move the water, rather they rely on the natural
buoyance force of hot water to circulate water from the solar collectors to the storage tank. This
method of heating water is very cost effective, reliable, and efficient. The system is manufactured under
license by SP Treatment Systems and consists of ONE (1) SP BlueWave 29 collector which have a gross
area of 2.9m2(31.4 ft2) and a 300 L (80USG) storage tank. The E model (Optional) comes with a 3.5 kW
auxiliary electric heating element installed in the solar storage tank to provide additional heat. With
between 95% to 100% of hot water needs met by the system, (see OG300 Certificate Performance
details), the optional heating element should only be required for households with extensively high hot
water use –beyond the SRCC and Energy Star draw levels.
Both systems are SRCC OG-100, OG-300 & Energy Star certified

4.3 Solar Thermal System Installation Instructions
4.3.1 Piping Installation
All pipes to and from the system must meet local building and plumbing codes for potable and hot water
and are supplied by the contractor. It is recommended that supply and return pipes from the home be
5/8” OD rigid copper. All pipes should be appropriately sloped (min 4°) to ensure the lowest point is the
bottom of the collector so that in the event of system decommissioning due to maintenance etc. the
water can be appropriately drained. See decommissioning and system diagram for additional details.
The piping and insulation on the solar system from the tank to the collectors and the collectors to the
tank is flexible stainless-steel hoses of size DN16 with 9 mm of insulation and protective UV coating
included which is included with the system. This hose is connected by following the steps in the pictorial
installation manual below.
There is a Danger during any draining of the system of scalding water at high pressure
being discharged. Caution must always be taken when discharging or draining the
system.
4.3.1.1 Piping Insulation
It is recommended that mains piping to the tank and return piping to the fixtures will be 5/8” OD copper
pipe and the recommended insulation will be ½” elastomeric foam R 3.4. Suitable protective cover of
the insulation must be installed to prevent damage from the elements. This can be a wrap or paint or
other means to protect the installation from the elements specifically moisture and UV.
4.3.2 Safety Relief Valve (Temperature & Pressure)
Safety relief valve dis-charge pipes shall be of rigid pipe that is approved for the temperature of the
system. The discharge pipe shall be the same diameter as the safety or relief valve outlet. Safety and
relief valves shall not discharge so as to be a hazard, a potential cause of damage or otherwise a
nuisance. Relief valves in partially filled collector loops capable of producing steam shall be discharged
to the outside of the structure. Where a relief valve discharges inside a structure or to the drainage
system, the installation shall conform to the plumbing code adopted by the authority having jurisdiction
or, in the absence of such code, the International Plumbing Code. Where a solar thermal system
component requiring a relief valve is located outside the structure, the termination shall be not more
than 6 inches (152 mm) above a splash block, a secured surface material or catchment method to pre-
vent damage.
4.3.3 Operating Indicators –Temperature gauges
It is recommended for the system the installation of two easy to read temperature gauges on the inlet
and outlet of the system, i.e., the cold mains water to the system and hot return water from the system.
These two gauges must be easily accessible by the system operator/owner and protected from the
elements. To determine whether the solar system is working, observe the temperature gauges when the
hot water is being used. The water returning from the collector on a sunny day at noon should be 75° -

80° C (165° - 175°F) before the mixing valve. Due to the high temperatures, mixing valves are required in
most jurisdictions.
4.3.4 Isolation Valves
Isolations valves must be installed for installation of the solar thermal system. These valves will be ball
valves and will be on the incoming mains water line and supply line to the fixtures as seen in the system
diagram in Section 3.1.
4.3.5 Check Valve
A check valve must be installed for installation of the solar thermal system. The valves insure water does
not thermosyphon in reverse to the house. Failure to install the check valve will greatly reduce the
operation of the system. As seen in the system diagram in Section 3.1
4.3.6 Thermostatic Mixing Valve (Anti-Scald Valve)
A thermostatic mixing valve must be installed in most jurisdictions to minimize the risk of scalding from
extremely hot water supplied by the Solar system. The installation shall conform to the plumbing code
adopted by the authority having jurisdiction or, in the absence of such code, the International Plumbing
Code. As seen in the system diagram in Section 3.1.
4.3.7 Pressure Regulating Valve
A pressure regulating value must be installed in the system to ensure the equipment is protected from
pressure building in the system. Failure to install the pressure regulator valve can result in pressures
exceeding warranty of the components. Ensure Pressure is set below system limits. As seen in the
system diagram in Section 3.1.
4.3.8 Drain Valve
A drain valve should be installed in the system for ease of servicing. Location of the drain valve should
be at the lowest point in the system. As seen in the system diagram in Section 3.1.

1. Ensure that all electrical connections are OFF, secure, and not exposed to elements or potential
leaks.
2. If start up is during the day please ensure the collectors are covered so as not to introduce cold
water into a hot collector. This could flash to steam cause scalding and damage to the system.
3. Open pressure relief valve to vent the storage tank to atmosphere.
4. Open the mains water line and begin filling the tank/collectors.
5. Once water starts coming out of pressure relief valve close valve and pressurise system.
6. Check each of the connections for leaks.
7. Remove covering from solar collectors.
8. Set mixing valve to desired temperature.
9. Turn electrical element on and set to desired temperature. (EL models only)
10. Ensure pressure relief valve is closed and is piped to a safe location as it may operate in over
temperature conditions causing hot water to be expelled and high pressure.
5.1.1 Expected Temperatures
During normal operation, the system will experience temperature on the inlet and outlet approximately:
-Inlet temperatures to the collector avg 55°- 60°C (130°-140°F)
-Outlet temperatures to the storage tank avg 75° - 80° (165° - 175°F)
5.2 Maintenance
5.2.1 Solar Collector Cleaning
The solar collectors do not require any maintenance; however, annual checks of the glass and
connections should be made to ensure there are no leaks, cracks etc. At this time, the glass can be
cleaned with a mild detergent if needed.
5.2.1 Hardware
It is recommended that all hardware is checked and tightened annually and/or after any sever weather.
5.2.2 Scale prevention in solar collectors
The solar collectors need to be flushed out using descaling solution once a year to ensure performance
and reliability. This is due to the fact that potable water is being heated directly in the collector and the
presence of CaCO3 (Calcium Carbonate) which precipitates out of water at temperatures above 50°C
(122°F) and can reduce heat transfer, lower flow rates and cause system failure if not treated. Failure to
follow these recommendations will void manufacturer warranty.
1. Isolate tank and shut off mains water.
2. Turn off electric connection to the system if applicable.
3. Cover the collectors to prevent heating descaling solution.
4. Remove the inlet and outlet connections to the collector using crescent wrench.
5. Using a descaling solution or other chemical for removing CaCO3 connect a hose to the inlet and
outlet connections.
6. Using a small circulating pump circulate descaling solution through the collectors for minimum
30 mins.

7. After minimum 30 mins replace descaling solution with fresh water and flush the collectors for
an additional 5 mins
8. Replace inlet and outlet connections.
9. Open mains water.
10. Remove cover from collectors.
11. Connect electrical element if applicable.
*To avoid possible burns or scalding due to hot fluid or pipes it is recommended that you conduct
maintenance on overcast day, morning, or evening when the sun it not strong.
5.2.3 Scale prevention in the storage tank
In order to prevent sale formation in the storage tank it should be drained one a year and the
magnesium anode replaced if it has lost more than 50% of its total mass or is completely covered in lime
scale or as necessary based on water quality. Electrical element and connections should be check at this
time to ensure no undue build up of scale.
5.2.4 Extended Absence
In the event the system is unused for an extended period i.e., more than one week and less than on
month, it is recommended that in the EL model the electrical breaker be turned off to conserve power. If
the system is going to be left unattended for longer than one month with no use it is recommended to
turn off the electric element and drain the system. This can be done by turning off the mains water and
opening the drain valve.
Danger! When draining the system water could be very hot. Caution must be taken when opening
drain valve and touching pipes.
Warning! Please exercise caution when turning on/off electrical power. If unsure call qualified
electrical contractor
5.2.5 Decommissioning
Steps for decommissioning the system
1. Turn of the breaker to the electrical element when applicable.
2. Close isolation valves and ensure no water is entering or leaving the system.
