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 for the controller 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 access panel or 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.
The MRO system may be equipped with a pretreatment system to remove chlorine
and chloramines. 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 IBT 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 will 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 verify that it is within the specified range (IBT pH
Water/Bicarbonate/Dialysate Test Strips P/N 97PH20901).
