Installation and technical Manual
5.Installation: General
1. General:
The boiler must be installed by a professional
plumber or heating engineer and must be
connected to the public low voltage network by
a competent person. WiseMining will not be
held responsible for faulty installations which
are performed by unqualified tradespeople.
2. Pipe Connections:
Every Sato has 22mm Compression pipe
connections that are clearly marked. Please
note that the boilers are supplied with blank
plugs for transit purposes that must be
removed before fitting. Mains Inlet, Hot Outlet,
Flow & Return connections are clearly marked
on the external case, under no circumstances
should these connections be reversed. If hot
capillary joints are to be used, these joints
must be made before connections to the boiler
are done.
3. Isolation Valves:
We recommend that full bore isolation valves
are fitted on the Flow, Return & Main Water
Supply Pipework. Such valves must be full
bore and not “ball valves”. The installation of
ball valves in the flow and return pipework will
reduce the flow rate through the boiler.
4. Boiler sizing:
Calculate the optimum mining power using the
forecasting tool on wisemining website. Check
with the wisemining team if doubts arise.
5. Insulation
Where practical, and if at all possible, we
recommend that all pipework be insulated..
This is to reduce heat loss and reduce high
cupboard temperatures from exposed
pipework.
6. Water Quality
In the presence of softener, the TH should
never be below 100ppm, preferably maintain a
value between 120 and 150ppm.
Maintain a PH greater than or equal to 7.
Limit the chloride level to 30mg/l.
6. Water Connections
Provisions must be made for the replacement
of water lost from the heating system (sealed
systems). There must be no direct connection
between the heating loop and the main water
supply. When mains water is required to fill the
system directly, all local water bylaws must be
observed, and any connection made must be
disconnected after use.
7. System pressures
All water tanks are tested to 6.0 bar. The
normal working pressure of the water tank
should be set to approx 2 / 2.5 bar. The heat
exchanger connected to the heating circuit is
designed to support 4 bars. Normal working
pressure inside should be set to approx 1 / 1.5
bar. All sealed systems should comply with the
relevant building regulations and standards,
including BS EN 13831 – Specification for
Expansion Vessels.
Please note: In order to protect the boiler, it is
imperative that the pre-installed magnesium
anode is removed and replaced at least
annually. Failure to carry out this action will
reduce tank lifespan.
8. System types
Sato can be used in various system designs.
Please refer to WiseMining for more details.
Note :
The current setup should be fully drained
(water tank and heating circuit) before
starting Sato’s installation.

Note : Primary return water temperature should not be more than 50°C. In fact, it should be as
low as possible. If it is higher than the temperature in Sato’s water tank, solenoid valves will be used
to divert the heating circuit and bypass Sato’s heat exchanger. This will then reduce mining time.

Installation and technical Manual
7.Installation Plumbing
Before any maintenance, make sure that the evaporator is fully closed. No water must ever get
into the evaporator tank which would cause damage to the mining equipment.
Water supply requirements:
Sato’s hot water cylinder operates at 2 / 2.5 bar (controlled by the inlet set) and is capable of
delivering over 50 litres per minute. The maximum possible water demand should be assessed by
taking into consideration that both hot and cold services are supplied simultaneously from the mains.
In order to meet the most common heating setup’s flow rate in domestic houses, Sato’s inlet
and outlet are BSP-¾”.
Cold mains pipework:
1. Run the cold water mains pipework to the location of the Sato. Take care not to run cold pipes close
to hot pipework as this will cause thermal transfer.
2. Install an isolating valve (not supplied) before the cylinder inlet and the T&P Relief valve. This will
allow you to stop the main water flow when draining Sato’s tank for maintenance.
3. Allow space for a 22mm x 22mm x 15mm tee and a valve between the solenoid valve and the
heating circuit inlet connection for the heating system filling/draining loop. The valve must be closed
after the system has been commissioned. It should only be opened when a draining of the heating
loop is required.
8.Electrical Connection
ALL ELECTRICAL CONNECTIONS MUST BE MADE BY A QUALIFIED ELECTRICIAN.
Load check must be taken into consideration when installing high power boilers. This will be carried
out by a qualified electrician.There may be an additional requirement to upgrade the incoming main
fuse supplying the property if other high power devices are used within the property. All boilers must
be protected at the meter position with a 30mA double pole RCD with a minimum of 3mm contact
separation accompanied by a suitably rated MCB. If the boiler is not fitted local to the meter position
then an additional isolation switch must be fitted local to the boiler for each supply. If the property is
prone to lightning strikes or power cuts it is recommended to install a suitable surge protection device
to the boiler supply. This will reduce the risk of damage to the boiler electronics during these events.
THIS APPLIANCE MUST BE EARTHED.
After completion of all electrical works, an electrical safety check should be carried out i.e. short
circuit, earth continuity, resistance to earth and polarity check, and all relevant Test Certificates
completed and issued to the customer.
Never open the side cover of the boiler until all power supplies to the boiler have been
disconnected.
ELECTRICAL CONNECTIONS:
The electrical supply cables can be routed into the boiler from the evaporator’s back side. Cable
grommets are supplied and fitted to the boiler's cable entry point. All cables should be secured to
meet current regulations.
9

Installation and technical Manual
The boiler connections are clearly marked inside the boiler L- Live, N - Neutral, E - Earth.
The supply is a permanent Feed connection to the boiler from the mains supply and should never be
isolated unless for maintenance purposes.
The Boiler circuit RCD should be independent of all other domestic circuits. It should not be
disconnected during any part of the day for better results. Since Sato’s power can be upgraded to
5000+W, the unit must be supplied with 4 mm² (11 AWG) cables.
BOILER PROTECTION:
The recommended protection for hard wired boilers are as follows:
Mining/Heating Power
Protection
0 - 1500 W
7 A
1500 W - 2500 W
12 A
2500 W - 3500 W
16 A
3500 W - 4500 W
21 A
4500 W - 5500 W
25 A
9. Internet Connection
Internet connection type : RJ45 Ethernet 10/100M
Sato Must be connected to the internet. It should be connected to your internet router 24/24h 7/7d.
Since wireless networks are not always available in the boiler room, we recommend the use of Power
Line Carrier sockets to easily bring ethernet cable to the boiler room.
PLC Sockets and Ethernet cables are provided.
No high speed internet connection is required. It should only be continuous. Your router should not be
turned off.

Installation and technical Manual
12. Annual Servicing
Before any maintenance, make sure that the evaporator is fully closed. No water must ever get
into the evaporator tank which would cause damage to the mining equipment.
A competent installer should carry out the following checks on an annual basis, ideally at the same
time as the annual boiler service.
1. The expansion relief valve on the inlet control set should be eased open allowing water to flow for 5
seconds. The valve should then be closed making sure it resets correctly. Always ensure that the
discharge pipework is allowing the water to drain away adequately. If not check for blockages etc. and
clear.
2. Ensure that the cylinder thermostat is working correctly and that it is controlling the water at a
temperature of between 60°C and 75°C
3. Check the pressure in all expansion vessels. Turn off the water supply to the unit and open a hot
tap first. Air or CO2 can usually be used to pressurise the expansion vessel.
4. Remove the head on the inlet control set by unscrewing, and clean the mesh filter within.
5. Replace the magnesium anode placed on the top of the water cylinder.
8. Ensure the central heating circuit is filled to 1.5 bar.
SERVICING MUST BE CARRIED OUT ANNUALLY & SHOULD ONLY BE CARRIED OUT
BY COMPETENT INSTALLERS AND ANY SPARE PARTS USED MUST BE
PURCHASED FROM WISEMINING, EXCEPT FOR REGULAR PLUMBING SERVICE.
NEVER BYPASS ANY SAFETY DEVICES OR OPERATE THE UNIT WITHOUT THEM
FULLY OPERATIONAL.
YOUR GUARANTEE MAY BE VOID WITHOUT PROOF OF ANNUAL SERVICING. THE
COMMISSIONING CERTIFICATE SUPPLIED AT THE REAR OF THIS MANUAL SHOULD
ALSO BE COMPLETED BY THE INSTALLER.
13. Other Servicing

17. Environmental Protection and Disposal
WiseMining uses the best possible technology and materials to reduce its impact on the environment.
This is why we try to provide products with long lifespan, and after sale support to prevent from
disposing of a working product.
If at some point the user wants to get rid of its Sato, special attention should be given to the disposing.
First, check on WiseMining Website the latest news about trade-in offers. Depending on the
conditions of your product, WiseMining may offer to recover your Sato to reuse and recycle its parts.
In case of local waste disposal please consider this :
- Most of the components are recyclable. The vessel, the evaporator’s tank, and the heat
exchanger are made of stainless steel.
- The frame and the outside walls are made of steel.
- The mining grid frame and the cartridges are made of aluminium
- All the electronic equipment should be disposed of as a WEEE.
- The heat transfer liquid must not be disposed of in the environment! It should be poured in an
empty bottle and disposed of in your local waste disposal as a chemical. Please also consider
sending it back to wisemining for reuse/recycling. Check wisemining.io for more information.
18. Energy Savings
Mining following heating demand:
Sato is designed to provide heating energy only if the user is needing it. No mining will be made
throwing away heat.
It is also designed to avoid heat sink and loss.
Central heating system:
With modern heating systems set around 20°C heat loss, the optimum temperature setting to apply to
your own boiler should be around 70°C or lower. This will allow a heating circuit return temperature
around 50°C which will make Sato more efficient.
Pipe insulation:
Every pipe should be insulated to prevent heat loss, especially if Sato is placed in a non living room.
This will also prevent the water from freezing which would damage the system.
