Start-Up / Operation

 

2.0.1 

Start-up check list 

 

a) 

Water  supply  and  Drain  Connections

these  should  be  connected  as  indicated 
under  Plumbing  and  in  accordance  with  the 
relevant local regulations.  An isolation valve 
should  be  adjacent  to  the  unit.  The 
connecting 

metal 

plumbing 

must 

be 

grounded close to the unit. 

b) 

Steam  Line:

  This  must  be  connected 

according to the installation instructions with 
adequate slope and support. 

c) 

Power  supply:

    Wiring  to  the  Vapanet  unit 

Should  be  by  a  qualified  electrician  and 
comply  with  the  relevant  regulations  using 
appropriately  sized  cable  and  cable  glands, 
with  disconnect  and  fuses  to  suit  the 
maximum fuse rating of the unit at the supply 
Voltage.    The  disconnect/fuses  should  be 
adjacent to the unit or within easy reach and 
readily accessible. 

d) 

Control  Connections:

    Ensure  the  control 

signal and security circuit are       
correctly connected according to the relevant 
instructions/diagrams. 

e) 

VAPANET  24v  /  9V  Control  Circuit 

Transformer: 

The 

standard 

24V             

transformer  used  in  the  units  has  primary 
winding  for  200V,  220/240V,  380V,  415V,  & 
440v  50/60Hz  connection  derived  from  the 
local electrical supply. 
Note:    60Hz  connection  must  be  specified 
with order as 230V 60Hz pump is required. 

f) 

The maximum output & kW  rating of the unit 
is  determined  by  a  Current  Set  Plug.  It  is 
therefore  possible  to  down  rate  units  to  any 
output, down to approximately 50% of the full 
rated output. 

g) 

Unit  Configuration  Plug  (U.C.P.).  Sets  the 
maximum current level for the unit. It is fitted 
directly onto the control P.C.B.  If a display is 
fitted,  it  is  the  only  resistor  required  to  be 
fitted  to  the  control  P.C.B..  However  if  no 
display is present additional resistors need to 
be  fitted,  to  provide  the microprocessor  with 
information  relating  to the control  signal  etc. 
For  ease  these  are  fitted  to  a  small  PCB 
fitted  to  CR4  of  the  PCB,  and  resistor 
selection  is  via  shorting  links,  see  control 
signal  selection  on  page  13.  If  insufficient 
information is available the unit will remain in 
the  “not_config”  state  (see  “Used  LED”  on 
page  19)  until  the  information  is  supplied. 
This  additional  information  is  provided  via 
the keypad – when the display is fitted. 

 

2.0.2 

Start-Up Instructions 

First check: 
a) 

That the transformer connection matches 
supply Voltage. 

b) 

That the security circuit is closed for unit 
operation. 

 
Close the electrical access panel. 
Turn on the water supply to the unit. 
Close disconnect/circuit breaker feeding supply to the 
unit. 
Close the On/Off switch. 
The  display  (if  fitted)  will  now  show  the  Set-Up 
procedure. 

Follow the procedure by: 

selecting:  the preferred language, 

-   

Attaching the control PCB to the Display. 

nominating:  the type/quality of  the supply 
water. 

nominating:  the control signal (or Vapac sensor 
when being used).

 

When the control signal has been nominated, the Set-
Up will be entered into the memory.  The Set-Up can 
then be checked by reading the information menu.  If 
an  error  has  been  made,  it  will  be  necessary  to  go 
back  to  the  Set-up  menu.  If  no  display  is  fitted  the 
information  is  set  using  the  jumpers  on  the  small 
resistor  PCB  1150634,  fitted  to  CR4  of  the  control 
PCB. 

2.0.3 

Commissioning/Start-Up 

Once the Set-Up procedure has been completed, the 
unit  is  available  to  operate  according  to  the 
requirements of the control signal. 
When starting  with  an empty cylinder,  the  VAPANET 
programme switches in the contactor and feeds water 
in until the water reaches the electrodes, and current 
starts  to  flow.  Thereafter  the  VAPANET  system  will 
continuously  monitor  and  control  the  conductivity  by 
adjusting the amount of water drained and fed into the 
cylinder. 
With  no  demand  the  LE  unit  has  the  right  hand  light 
will  flash  red  the  left  hand  light  will  be  off. When  the 
demand increases or the unit is switched on the cyl 1 
LED  will  flashing  green  Amber  at  rate  depending  on 
the  demand  input  and  the  actual  current  drawn,  the 
actual  run  current  of  each  cylinder  is  monitored  and 
until the actual current has two feed above 95 % the 
LED will flash green amber when the current is above 
95%  for  two  consecutive  feed  the  light  will  flash  red.  
If  twin  cylinder  unit  the  second  cylinder  starts  in  the 
same way but only when the demand is above 50% to 
unit 

2.0.4 

Features 

of 

VAPANET 

Electode 

Boiler Unit 

The VAPANET system of control is designed to adjust 
the  function  to  keep  the  unit  operating  in  the  face  of 
changing  water  quality  in  the  cylinder  and  changing 
electrode condition even if, in an adverse operational 
circumstance, this results in some reduction in output 
while the situation exists. 

 

 

Foaming protection * 

In particular, the VAPANET is designed to prevent the 
onset of foaming and to introduce corrective drainage 
to keep the unit working.

 

 
 

Automatic switch-off 

The VAPANET PCB will stop operating in response to 
extreme fault conditions identified as: 
Drain Fault STOP (no drain function) 
Feed Fault STOP (water not reaching cylinder) 
In  each  case,  the  display  will  show  the  STOP 
condition and a Help Message, the User LED’s on the 
fascia will indicate the condition see table on page 16. 
A  warning  signal  will  be  available  for  remote 
indication.  The STOP condition of a VAPANET PCB 
will be cleared via the key pad if a display is fitted or 
by  pressing  the  reset  button  on  the  fascia  –  then 
switching  the  unit  off  and  on. 

THIS  ACTION  SHOULD 

ONLY BE TAKEN ONCE THE CAUSE OF THE PROBLEM 
HAS BEEN ASCERTAINED AND RECTIFIED.
