CENTRA – MDS/LDS/RDS US Operator Manual 

ELGA 

Page 32

 

CENTRA – MDS/LDS/RDS US Version 01 – 08/14 

Step 4 -  Installation of ion-exchange/purification media 
cylinders (optional with CENTRA – RDS US) 

Note:  It is highly recommended that ion-

exchange/purification media 

cylinders be 

flushed to drain locally before being installed in 
the distribution loop. 

1. 

ENSURE the 

ion-exchange/purification media

 

cylinders are installed as described in section 9.4 - 
Installation / replacement of ion-exchange cylinders. 

2. 

OPEN point of use in distribution loop and direct full 
flow to drain to flush cylinder (recommended flush is 
a minimum of three bed volume or as appropriate for 
the application). 

3. 

OPEN isolating valve (V6) and close bypass valve 
(V7). See flow diagram 3.3 Section 3. 

4. 

CLOSE point of use. 

Note:  If an ion-exchange cylinder is installed into the 

recirculation loop of a CENTRA  –  RDS  US  the 
quality monitoring will require resetting. Contact 
technical support or your local ELGA LabWater 
representative. 

Step 5 - Distribution loop pressure adjustment 

1. 

LOCATE the pressure adjustment valve. 

2. 

ADJUST the pressure in the distribution loop by 
TURNING the knob ANTI-CLOCKWISE to decrease 
pressure and then use the lock nut to stop it moving. 

Note:  If the valve starts to make a high pitch noises at 

the required settings adjust the valve slightly and 
the noise will stop. The noise is caused by the 
matching of the natural harmonics of the spring 
within the valve and is not a malfunction of the 
CENTRA

. 

 

CAUTION! 

The CENTRA pressure regulator is factory set 
to maintain a pressure of 3 bar (typically) at 
the end of the distribution loop.  

 

WARNING!  Pressure in the distribution loop may 

increase, due to filters blocking etc. which 
may lead to increased distribution pressure (6 
bar maximum). The CENTRA – RDS US unit is 
fitted with sensors to detect high pressure 
situations and will shut the unit off if >6 bar is 
detected.  Any equipment installed within the 
distribution loop should be rated to 6 bar to 
ensure the equipment remains within safe 
operating limits. 

 

To adjust the pressure in the distribution loop requires specialist 
equipment and it is recommended that changes are made by an 
ELGA LabWater Service Engineer.
