In response to questions concerning operations of Better Water LLC Portable ROs without dialysis
personnel/trained operators in attendance (within visual or audible range of the units) during the entire
treatment, Better Water LLC issues the following:
Currently, on all PB1 and PB2 Portable RO units manufactured prior to Jan. 12, 2012, the following occurs
during a low pressure default condition:
1) A visual alarm light is illuminated.
2) The inlet solenoid valve remains open / energized.
3) The pump motor is turned off (this is to protect the pump head from running dry).
4) The Water Quality Monitor is turned off.
5) The water feeding the dialysis machine continues to flow through the Pretreatment, RO membrane and
.05 final filter (PB2 only).
If the customer desires changes to their unit allowing the Water Quality Monitor to remain on and the Inlet
Solenoid Valve to close in a low water pressure default condition, shutting off water to the dialysis machine,
see the following instructions.
In order to determine whether your Portable RO unit can be modified, see Illustrations 1 and 2.
Your control box must match exactly, having either
a Contactor Relay (Illustration 1
– see Page 2)
or a Blade-type Relay (Illustration 2
– see Page 4), to be modified.
Any deviation in appearance from Illustration 1 or 2 prevents the unit from being modified.
For units matching exactly either Illustration 1 or 2, modifications are available:
Field modifications are simple wire relocations taking about 15 minutes to complete. See illustrations and
instructions.
*** Should you wish Better Water LLC to make these wire relocation modifications, verification and testing,
please call Better Water LLC to receive a RGA, then issue a Purchase Order for Labor / Testing charge of
$125.00 (as of 1/11/12).
If you have identified your unit as having a Contactor Relay, see Pages 2, 3 and 6.
If you have identified your unit as having a Blade-type Relay, see Pages 4, 5 and 6.
If you would like to speak to Technical Support prior to making
modifications or need assistance during the process,
please call (615) 355-
6063, and press “1”.
All Better Water LLC Portable RO units manufactured on or after
Jan. 12, 2012 will include this modification as a standard.
