system in accordance with the manu-
facturer’s instructions to de-energize
the solenoid valve. Check the Solenoid
Valve drain for leaks. Any leaks must
be corrected before proceeding to the
next step.
Step 7. Slowly open the Main Control
Valve. Close the Main Drain Valve as
soon as water discharges from the
drain connection. Observe the Auto-
matic Drain Valve for leaks. If there are
leaks, determine/correct the cause of
the leakage problem. If there are no
leaks, the DV-5 Valve is ready to be
placed in service and the Main Control
Valve must then be fully opened.
NOTE
When the Main Control Valve is
opened, the pressure on the Dia-
phragm Chamber may increase. This
increase in pressure is normal, and if
the pressure is greater than 250 psi
(17,2bar),thepressureistobere-
lieved by partially and temporarily
opening the Manual Control Station;
however, do not allow the pressure as
indicated on the Diaphragm Chamber
Pressure Gauge to drop below the
supply pressure shown on the Water
Supply Pressure Gauge, since this ac-
tion may result in tripping of the DV-5
Valve.
Quarterly Supervisory Low Pres-
sure Alarm Test Procedure
Proper operation of the Supervisory
Low Pressure Alarm Switch must be
performed quarterly as follows:
Step 1. Crack open the System Main
Drain Valve for the Riser Check Valve
(Item P7, Figure 2A) to slowly relieve
supervisory air pressure from the sys-
tem. Verify that the Supervisory Low
Pressure Alarm Switch is operational
and that the low pressure set point is
approximately 5 psi (0,34 bar).
Step 2. Close the System Main Drain
Valve (Item P7, Figure 2A) and allow
the system supervisory pressure of 10
plus or minus 2 psi (0,69 plus or minus
0,14 bar) to be automatically re-estab-
lished. The Supervisory Low Pressure
Alarm Switch should return to its “nor-
mal” condition.
Pressure Relief Valve Maintenance
Over pressurization of the system pip-
ing with air will result in the opening of
the Pressure Relief Valve (Item P4,
Fig. 2A). If the Relief Valve continues
to bleed air after the system pressure
has been reduced to its normal super-
visory pressure range of 10 plus or
minus 2 psi (0,69 plus or minus 0,14
bar), most likely debris became lodged
in the seating area. To help clean the
seating area, slowly pull up on the ring
at the top of the Relief Valve to allow a
full flow of air through the Relief Valve,
and then release the ring to allow the
Relief Valve to snap closed.Repeat the
cleaning procedure as necessary
