1.3 Check Tundish is positioned so that any spillage or spray from the Tundish would

not contact any electrical components.

1.4 Check ALL wiring connections have been made.

Check cylinder temperature sensor is connected to ‘temp sensor’ terminals 3 & 4.
Check cylinder over temperature cut-out is connected to ‘O-T’ terminals 1 & 2 (see
figs. 3-3a and 3-3b).

1.5 Check the required earth continuity conductors have been fitted.

STAGE 2 - DHW PRE-FILL CHECK
2.1 Check the hot water heating discharge pipes and Tundish are correctly installed to

conform to the Building Regulations G3.

2.2 Check all pipe connections are tight and no joints have been left unsoldered.
2.3 Check ALL drain cocks are closed.
2.4 If fitted, check that the Scale Protection Device or Water Softener has been fitted

according to manufacturers instructions.

STAGE 3 - FILLING DHW SYSTEM
3.1 Open all shut off valves.
3.2 Open the incoming water isolating valve (mains stopcock) to the Electrastream and

allow the unit to fill.

3.3 Open all domestic taps in turn to purge air.
3.4 Check system for leaks including around the Tri-Core Heater.
3.5 Check no water is discharging from any TPRV or PRV.
3.6 Test the operation of the TPRV and PRV by turning the manual test cap and ensure

the water flows freely and safely to waste.

3.7 Test the operation of the Combination Valve PRV by turning the manual test cap and

ensure the water flows freely and safely to waste.

3.8 Set hot water Mixing Valve to ‘max.’

STAGE 4 - DRAIN DHW SYSTEM
4.1 Turn off incoming water isolating valve (mains stop cock).
4.2 Using hose and suitable containers, drain all water from the cylinder and pipework

using drain cocks. The cylinder will not fully drain without the use of a hose - see
page 36.

Note
DHW = Domestic Hot Water.

IMPORTANT It is the responsibility
of the installer to ensure that the
Electrastream System is properly
commissioned.
Should the commissioning not be
carried out, then the manufacturers
guarantee and any extended
warranty, will become null and

void.
The Guarantee Form MUST be
completed and returned to GAH
(HEATING PRODUCTS) in the
prepaid envelope provided.
