bpr Dialflow Regulator, Instructions For Use Manual, Page: 6 / 8

5.1.3. External Leak Test
Attach a fresh, dry hose to the outlet barb and connect the other end of the hose to a
calibrated flowmeter in the correct range for the device under test.
5.1.4. Flow Test
Verify flow rates at all flow settings against those given in the Device Specification.
5.2. Service
It is recommended ranges A and E be serviced every 2 years, ranges C and D every 4
years to ensure the device continues to perform in accordance to its specification. All
Dialflow Regulators have a Service Due date on their label, indicating when the next
service is due.
Warning! Servicing must be carried out by a suitably qualified person working in a
controlled environment.
Full details of the recommended servicing requirements can be found in the Service
Manual. The Service Manual can be obtained from your local BPR Medical distributor,
details of which can be found at
www.bprmedical.com . Complete the service in
accordance with the instructions given in the Service Manual or return the device to a
recognised BPR Medical Service Centre on or before the date shown.
