Step 7.
Replace all damaged or operated sprinklers. Replacement sprinklers must be of the same type and
temperature rating as those that operated.
TICE
In order to prevent the possibility of a subsequent operation of an overheated solder type sprinkler, any solder
type sprinklers possibly exposed to a temperature greater than their maximum rated ambient must also be
replaced.
Step 8.
Service the air dryer, if applicable, in accordance with the manufacturer’s instructions.
Step 9.
De-energize the Solenoid Valve.
For Electric/Electric Actuation, de-energize the Solenoid Valve (7) via the Potter RCDS-1 Releasing Circuit
Disable Switch, or equivalent.
For Electric/Pneumatic Actuation, de-energize the Solenoid Valve (7) by resetting the electric detection system
in accordance with the manufacturer's instructions.
Step 10.
Operate (open) the Manual Control Station (8) and then open the Diaphragm Supply Valve (5). After
unaerated water ceases to discharge from the Manual Control Station (8) drain tube, slowly close the operating
lever by pushing it up. Do not close the hinged cover at this time.
Step 11.
After allowing water to flow out of the Manual Reset Actuator (6) drain tube until aerated water ceases
to discharge, reset the Manual Reset Actuator (6) by pressing the Reset Knob and hold until the pressure builds
and reaches approximately 15 psi (1,0 bar) on the Diaphragm Gauge (15) and water stops flowing from its drain
tube. Pressure will then build up in the DV-5A Diaphragm Chamber.
Step 12.
Inspect the actuation device drain connections. Any leaks must be corrected before proceeding to the
next step.
Electric/Electric actuation drain connection to be inspected are from the Manual Control Station (8) and Sole-
noid Valve (7) shown in Figure 4.
Electric/Pneumatic actuation drain connection to be inspected are from the Manual Control Station (8) and Dry
Pilot Actuator (31) shown in Figure 5.
Step 13.
Verify the ability for the DV-5A Diaphragm to hold pressure as follows:
With the diaphragm chamber pressurized per Step 11, temporarily close the Diaphragm Supply Valve (5), and
then observe the Diaphragm Gauge (15) for a drop in pressure.
If a drop in pressure is noted, the DV-5A Diaphragm is to be replaced and/or any leaks must be corrected
before proceeding to the next step.
If the Diaphragm Gauge (15) indicates no drop in pressure, re-open the Diaphragm Supply Valve (5) and proceed
to the next step.
Step 14.
Open the Air Supply Valve (27) and allow the system to automatically re-establish its nominal system
air pressure. Observe the Automatic Drain Valve (3) for leaks. If there are leaks, determine/correct the cause of
the leakage problem.
Nominal system air pressure for Electric/Electric Actuation is typically 15 psi (1,0 bar).
Nominal system air pressure for Electric/Pneumatic Actuation is per Graph B.
