Quick Start

This manual applies to: PW860/861/864/865/866/867/875

1. This recorder comes with one (1) AA battery installed.

2. When installing recorder (1/4 in male NPT pressure connection) always tighten the fitting instead of twisting the

instrument case. Use a 5/8 in wrench. We recommend wrapping the pressure fitting with pipe tape before installing to

prevent leaks.

3. Replace chart paper with a new chart.

4. Set the time by inserting a coin into the chart hub and turning clockwise until the correct hour is referenced by the time

indicator. (Time indicator is directly to the right and below the pen tip.)

5. Remove protective pen cap.

6. Turn the recorder On. The “On/Off” switch is located inside the door on the dial plate.

PW8Water Resistant Enclosure

The PW8 features an IP66 enclosure. In order to maintain the IP66 rating, the battery/switch cover on the back of the unit,

must be screwed down tightly at all points. The door must be closed tightly using the two side latches.

It is strongly recommended that the case door gasket be greased occasionally using a standard silicone rubber grease. The

more the door is opened and closed, the more frequently grease should be applied.

The Door and Battery Cover gaskets should maintain the IP66 rating for 1 year under normal use. To replace gaskets,
