SECTION 4, MRO STARTUP & OPERATION
4.1
CAUTION
NOTE: This entire Operations Manual should be read before operating or servicing
the MRO system. The Operations Manual should then be kept near the
system and used as a reference and troubleshooting guide.
WARNING: This Reverse Osmosis System (RO) contains a preservative solution to
prevent microbiological growth and freezing. Discard all product water for at
least two hours of operation before placing the RO in service.
CAUTION:
No person should attempt to operate or service the MRO without prior
authorization or instruction from your medical facility director.
The following operating or water supply conditions could cause an accident or the MRO system
to fail:
1. The electrical source must be single phase, 3-conductor type provided with a hospital grade
receptacle and a ground fault interrupter (GFI) at 115V, 60Hz. The proper polarity and
ground integrity must be initially checked and thereafter maintained. Failure to do so may
result in electrical shock to the operator or patient. It is suggested that the MRO be placed
on an electrical supply with emergency backup.
2. The MRO must only be plugged directly into a GFI receptacle. It must not be plugged into
an extension cord or power strip that could cause low amperage.
3. All local plumbing and electrical requirements should be met.
To avoid electrical shock, always unplug the MRO system before opening the
face of the electrical controller.
4. Incoming water should be between 41° F and 90° F (5° C and 33° C). It is not
recommended to use water at temperatures below 41° F (5° C) because it will reduce
membrane performance significantly. Use only the cold water supply unless using an
automatic blending valve to get 77° F (25° C) water. Never use water warmer than 90° F
(33° C).
5. Water with silt density index (SDI) above 5 SDI will foul the membrane.
6. It is important to test for chlorine and chloramines at the CHLORAMINES SAMPLE PORT
before each use of the system. Chlorine will deteriorate the membrane and cause system
failure. It is recommended to use a Total Chlorine test kit, such as Water Check 2 Low
Level Chlorine/Chloramines Test Strips (P/N 97CM20201).
7. Incoming tap water pH should be within EPA National Secondary Drinking Water
Regulations of 6.5 - 8.5. Incoming tap water with pH higher or lower than the regulation may
cause higher conductivity in the product water. If the water changes drastically, the
membrane will be harder to clean. Periodically check the pH of the incoming tap water to
