Preventative Maintenance and
Fitting Spare Parts
Warning! Isolate power to the DRV40. Ensure that the circulating pump is not
operating.
DRV40 components should be inspected annually, or more frequently where acknowledged site conditions such
as high mineral content water dictate.
Each DRV40 has a serial number that is maintained on file with the technical department at Armstrong.
For any installation, operation, maintenance or technical support details not covered in this guide, please call
our Technical Department quoting the model and / or serial number.
Batteries
Batteries are supplied to ensure the DRV switches to Full Cold in the event of a primary power supply failure,
they should not be considered to be a backup power supply.
Battery life is variable depending upon usage. A battery error message appears on the DRV display when they
require replacing.
Where primary power supply failure occurs regularly or the DRV is installed within a supply system where safety
is critical, the batteries must be changed at least every 12 months as part of an annual maintenance routine.
In noncritical systems or where battery usage is low, longer replacement cycles may be considered up to a
maximum of 5 years. Inspection of critical components and / or assemblies.
O - Rings / Seals
All 'wetted' O -Rings / Seals must be replaced at least every 12 months as part of an annual maintenance routine.
In systems where water quality conditions are poor, more frequent replacement may be required.
Strainers
All supply strainers must be thoroughly cleaned at least every 12 months as part of an annual maintenance
routine. Cleaning includes physically taking the strainer screen / basket out of the body and cleaning as well as
flushing water through the body. In systems where water quality conditions are poor, more frequent cleaning
may be required.
