• Slightly increase or decrease the outlet pressure until the noise disappears.
• Clean the filter cartridge as described in the Installation section.
• Replace the screen and O-rings.
• Replace the cartridge as shown in Fig. 3.
• Replace bonnet or cartridge if damaged.
• To avoid future freeze-up:
— Temporarily (slightly) open a downstream faucet if the DS05 will be exposed
to temperatures below 32°F (0°C). The slight water flow will eliminate
freeze-up.
— Move the DS05 to a location with an ambient temperature above 32°F (0°C)
If it is currently exposed to prolonged temperatures below 32°F (0°C).
• DS05 is functioning properly. No action is necessary. The pressure decrease is
characteristic of all direct acting pressure regulating valves and is referred to as
falloff.
