WRO 300
Step 2 Collect a water sample either from the product water line or
from the dialysis machine according to the caution above.
Step 3 Test for disinfectant residuals with Minncare
®
Residual Per-
oxide test strips or other approved test strips or methods.
Step 4 Confirm by pressing until light goes out. Indication
remains on.
Step 5 Remove any tag indicating storage with disinfectant.
If residuals are detected after starting the WRO 300 by pressing
until the light goes on, repeat the residual test every five minutes until
no residuals are detected.
3.1.5 Central Chem
The central chem disinfects the WRO and also sends disinfectant into
the dialysis machine. For more detailed information on how to perform
central chem together with Gambro
®
dialysis machines, please contact
Technical Service.
Follow the instructions in the Chemical Disinfection Procedure on
page 18 by starting at Step 3 and continuing to Step 13.
In Step 8 select the preferred central chem protocol in the CHEM
SELECT menu.
CAUTION
If the produced disinfection solution is fed into a device other
than Gambro
®
dialysis machines, it is the user’s responsibility
to ensure that the connected device is compatible with per-
acetic acid disinfectants and to establish the procedure for the
WRO in combination with the connected device.
CAUTION
As the disinfection solution produced by the WRO will enter
any device connected to the quick connector on the product
water loop, residual test after disinfection must be performed
on the connected device in accordance with the Operator’s
Manual for the connected device.
