8. SANITIZATION PROCEDURES
8.1 Liquid sanitization
The normal sanitization procedure for the
MEDICA
unit is to sanitize
the Reverse Osmosis (RO) module and associated pipework (
8.1.1
). If
required, the unit and docking vessel/reservoir may also be sanitized
(
8.1.2
).
8.1.1 RO sanitization procedure
The RO is sanitized to reduce the growth of microbiological
contamination within the RO module. The
MEDICA
has a built-in
sanitization port, which allows the sterilant to be introduced into the
water feeding the RO. Please read this entire section to become
familiar with the procedure before you start.
The sanitization frequency required is dependent on the feedwater,
local environment, usage patterns and application. As a general rule,
ELGA LabWater recommends sanitization of the RO at 6 monthly
intervals. However, the period between sanitizations could be
extended in particular circumstances. For example, microbial growth
will usually be lower with clean feed water, well-maintained pre-
treatment, low temperatures and heavy usage.

FACEMASK. DO NOT BREATHE FUMES OR ALLOW
