the Electrastream components. When used in the manner for
which they are intended they do not present any known hazard.

ELECTRIC

ELECTRIC
The Cylinder Tri-Core Heater, Pump, Thermostats and Contactor
Box all have electrical supply of 230V (enough to endanger
life).
Always isolate before connection, adjustment, servicing and
repair.
When the Tri-Core Heater cover is removed high power live
electrical terminals are exposed.
ISOLATE THE TRI-CORE HEATER BEFORE REMOVING ITS
COVER.
Earth protection - Earth Continuity Conductors must be fitted
and must comply with IEE Wiring Regulations.

IMPORTANT Under no circumstances should the system be operated
without the heating PRV fitted and working correctly.

4-4.5 Heating PRV Discharge Pipe

The outlet from the heating PRV must be piped using 15mm copper pipe to the tundish
then to a visible position outside the dwelling. The pipe must have a continuous fall and
ideally be terminated over a drain.
The heating PRV may be plumbed to the hot water system TPRV discharge prior to the
Tundish, see fig. 4-4a.
The PRV discharge must comply with Building Regulations G3 refer to pages 40-42.

IMPORTANT Scalding water and steam can be emitted from the
discharge pipe. Position the discharge so there is no hazard to property
or people (especially children).

4-4.6 Heating System Expansion Vessel (red)

Maximum charge pressure

1.5 Bar Maximum working temperature

90°C

Pre-charge pressure

1 Bar Maximum working pressure

3 Bar

Capacity

8 litres for maximum system expansion of 7 litres.

An expansion vessel and mounting kit is supplied, this is suitable for systems with a
static head of up to 5 metres.  If the static head is greater than 5 metres the charge
pressure of the expansion vessel will need to be increased.  Increase the pressure using a
standard car tyre pump and pressure gauge when the system is empty (zero pressure).
Expansion vessels are suitable for systems requiring a maximum expansion of 7 litres as
detailed above. For systems requiring more expansion a second expansion vessel will be
required.  BS7074 Part 1 includes information on this requirement.
Clearance is required on top of the vessel to access the pressure valve.

4-4.7 Filling Loop

A Filling Loop comprising a flexible hose, double check valve and an isolating valve is
supplied for filling and topping up the system.
