Part 1 – Operating Instructions
(Eco)RO Dia II
Part 1 • Chapter 2
2.1 Functional features
• Unauthorized operating states that could endanger the connected medical products or even the
patients are prevented by measuring equipment and related control measures (alarm and error
functions).
• Emergency operation with soft water is possible (following doctor's approval)
• Modular design: the system performance can be changed simply by replacing/supplementing the
pumps and membranes
• One-stage emergency operation possible via the first reverse osmosis stage or the second osmosis
membrane.
• Standby mode: when it is not in permeate mode, the system regularly switches to a rinsing mode to
prevent microbiological growth.
• Impulse shear force rinsing of the ring piping (high flow speed) during standby to prevent biofilm
formation.
• Impulse return rinsing: the EcoRO Dia versions feature a regular rinsing mode for the membranes to
remove deposits on the membranes.
2.2 Important performance features
• Production of pure water (permeate with a low salt concentration) to dilute haemodialysis
concentrates.
2.3 Application regulations
• No products or media are to be processed which, under the influence of pressure and temperature,
tend to cause uncontrolled reactions such as an increase in viscosity, increase in temperature,
hardening, frothing or the generation of gas which could cause the system to exceed limit values
even for only a short time.
• The raw water must be treated in a correctly design pre-treatment stage.
• A pre-treatment stage can only be carried out subject to previous water analysis or according to the
data provided by municipal water suppliers. The values of the incoming raw water must be checked
and recorded once a year. (See →Part 1, chapter 2 ff).
• A water analysis must be requested by the system operator once a year.
• The municipal water suppliers must be consulted regarding the water quality/chlorination.
You can find a corresponding sample letter in →Part 2, chapter 10.
• The local regulations for connecting the concentrate drainage to the waste water system must be
observed (this also applies to the draining of disinfectants).
• Supply and waste water systems must be properly installed according to EN 1717 (2000). Local
regulations for drinking water and waste water installations must be observed in individual cases.
• Other application purposes may be possible under certain circumstances but they must be agreed in
advance with the manufacturer.
• Intended use also includes adherence to the commissioning, usage and maintenance instructions
provided by the manufacturer which are part of these operating instructions.
• The system may only be transported, installed, used and repaired by specialists.
• Commissioning, operation and maintenance may only be carried out by authorized, trained and
instructed specialists. Electrical work may only be carried out by authorized, trained and instructed
electricians.
• Any other use of the system is considered as non-intended use. The manufacturer shall not be liable
for any damage resulting from this.
The chemical and microbial water parameters for the permeate must be checked every year
against the values specified in the European Pharmacopoeia (2004) or ISO 13959:2009.
