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.
