2.0  INSTALLATION

2.3 COMMISSIONING

It is essential that all systems function properly for optimum performance.  To achieve 
this, the primary system should be commissioned in accordance with good practice 
and generally in accordance with the requirements of BS 6798, BS 5449 and BS 7593.
Full  details  of  the  requirements  are  given  in  PAS  33:1999  under  section  10 
Commissioning - See Section 10.

Cleansing the Primary System

When  using  either  cleansing  or  corrosion  inhibitor  chemical,  the  manufacturers 
instructions must be followed.

When determining the quantity of cleanser required, be sure to allow for the 
increased volume of water in the primary circuit due to the thermal store. See 
section 1.2 Technical Data for volumes.

Primary Water System Treatment

Although  the  ElectraMate  2000  has  no  special  water  treatment  requirements,  the 
radiators and other parts of the circuit will benefit from the application of a scale and 
corrosion inhibitor such as Sentinel X100 or a protector such as Fernox MB1.
When determining the quantity of inhibitor required, be sure to allow for the increased 
volume  of  water  in  the  primary  circuit  due  to  the  thermal  store  -  see  Section  1.2 
Technical Data for volumes - See Section 10.

The  following  procedures  should  be  used  during  the  final  fill/before 
commissioning the appliance.

1. 

To isolate the heating element temporarily remove the two 30 amp fuses and put 
them in a safe place.

2. 

Check the air pressure in the expansion vessel is set to the correct pressure and 
adjust if necessary.

3. 

Open the automatic air vent which is positioned at the top of the appliance. 

4. 

Open the incoming stop valve and fill the domestic mains cold and hot water 
systems - see Section 10.

5. 

Open the 90º angle isolating valve provided immediately upstream of the C.A 
Valve to fill the appliance/sealed heating system.   The whole of the primary sealed 
heating system will automatically be filled to 1.0 bar with potable water through 
the pressure regulating and CA type backflow prevention valves provided as part 
of the ElectraMate 2000.   Add inhibitor to the system in the normal way whilst the 
system is filling.  Once full check the whole of the primary heating and domestic 
hot and cold distribution systems for leaks - See Section 10.

6. 

Once the system has been filled the electrical connection and system controls 
should be checked in line with page 25.  Once this has been done the system 
should  be  operated  for  a  few  minutes  without  the  heating  elements  being 
switched on which will allow any air trapped in the system to be vented.  The 
appliance should be switched on and the heating pump should be activated by 
operating the programmable room thermostat in line with the instructions on 
page 25.  The automatic air vent should remain open until all air has been removed 
from the system.

NOTE :  Pump speeds should be set as follows:
The space heating pump should be set at a speed at which the temperature difference 
across the heating circuit close to the unit boiler is at least 11°C or as specified by the 
system designers. The pump characteristics are shown in Section 1.2 Technical Data.
The domestic hot water plate heat exchanger pump should always be set at maximum 
speed (i.e. speed III)
The boiler flow pump should always be set at speed III - See Section 10.

Once  all  the  air  has  been  vented  from  the 
system  the  two  30  amp  fuses  should  be 
replaced and the heating element should be 
checked for its correct operation which will be 
indicated by a current draw of approximately 
45 amps on the incoming supply.

Check the operation of the appliance in line 
with the instructions on page 26 after all the 
air in the system has been vented, which could 
be several days, the automatic air vent should 
be closed to prevent any possibility of a leak 
in the event that any system debris finds its 
way into the valve.

ONCE THE  COMMISSIONING  PROCESS  IS 
COMPLETE DO NOT SWITCH THIS APPLIANCE 
OFF AT THE ISOLATOR SWITCH EVEN WHEN 
THE PROPERTY IS EMPTY.  THE PUMPS ARE 
TURNED AUTOMATICALLY EVERY 24 HOURS 
TO  PREVENT THEM  STICKING  AND THIS 
WILL  NOT  HAPPEN  IF THE  APPLIANCE  IS 
ISOLATED.  THE ROOM THERMOSTAT CAN 
BE  TURNED AND IN THIS CASE THE HEATING 
WILL NOT OPERATE.  THE RUNNING COSTS 
WILL THEN ONLY BE ENOUGH TO KEEP THE 
APPLIANCE ON STANDBY.

Powerflushing/Cleaning  of  the  Heating 
System

If  it  is  proposed  to ‘powerflush’  the  heating 
system  we  would  recommend  that  the 
ElectraMate  appliance  is  isolated  from  the 
heating system being cleaned.  Failure to do 
this could seriously damage the appliance.

When  carrying  out  the  work  always  comply 
fully with the manufacturers instructions for 
the powerflushing equipment being used- See 
Section 10.

If in any doubt please consult our Technical ).
