Trying to understand the Nipro Surdial 55+ manual, kinda stuck here
I've got a tech question about the hardware 'cause I'm completely lost with these configurations. So, I work in the engineering department, and we were assigned to inspect a Nipro Surdial 55+ machine. It started showing an error during dialysate circuit testing after the department upgrade. I have never been so involved with Japanese equipment that I know nothing of their self-diagnostic system, and I am figuring it out myself so that I won't have to call the service technicians who have very high charges. I was up late last night checking the technical information on manualmachine.com where there are instructions on maintenance and sensor calibration codes. However, I am still unsure of the sealing method of one of the parts. So, does anyone know if the pump seals can be replaced by yourself or they are only sold in complete modular units?
Listen, these Nipro machines are really sensitive to pressure in the lines. If the pump is leaking, it’s better not to do any “DIY fixes” and just install the original repair kit, because regular rubber seals won’t last long there due to the aggressive cleaning cycles. By the way, have you tried clearing the error log through the service menu, or does it pop up again immediately after the test? If I were you, I’d also take another look at the blood leak detector sensor — they often get clogged and give false readings. And what about the hydraulic filters, have you checked if they’re clean yet?
