Page 3: Ws755 Checklist Page
Congratulations on your purchase of the Global Water WS755 Water Sampler. This instrument has been quality tested and approved for accurate and reliable operation. We are confident that you will find the WS755 to be a valuable asset for your applications. Should you require assistance, our technical staff will be happy to help. - Page 4 The WS755 Sampler can take two individual “time weighted” composite samples, or the sampler can be set to take full-bottle discrete or “Grab” samples. Each pump has its own sample bottle and control for setting the size of individual samples.

Page 5: Installing The Water Sampler
Global Water IV. Installing the Water Sampler a. The sampler should be placed upright (it will not work if placed on its back or side). b. Remove the pickup hoses and connect to the sampler using the quick- disconnect fittings on the side of the enclosure. Place the protective caps over the protective quick-disconnect plugs and save for future use. -
Page 6: The Control Panel
Global Water The Control Panel 1. Pump One. 2. Pump Two. 3. Start Delay: This setting delays sampling by a preset amount of time. If no delay is desired, set the control to zero. Only the first sample taken by each pump is delayed, except as described later in the section titled “External Trigger Mode”. - Page 7 Global Water more detail later in the section titled “External Trigger Mode”. Refer to the Specifications section for details about the input pulse requirements. 8. Pulse Out: These outputs send a pulse to an optional recording or monitoring device each time the corresponding pump starts, allowing the time of the sample event to be recorded.

Page 8: Composite Sampling
Global Water VI. Composite Sampling A composite sample is a series of smaller samples put into the same bottle, thus showing an “average” sample over time. Set the Interval control to the desired time between samples (do not select the External Trigger position). Set the Size control for the corresponding pump to the desired sample size. -
Page 9: Mixed Sampling
Global Water VIII. Mixed Sampling, Composite and Discrete Sampler The WS755 Sampler can be configured as both a composite and discrete sampler at the same time since each pump has a separate Size control. Set one pump’s size setting to the desired composite sample size and the other to “Full”. - Page 10 Flow Proportional Sampling a. To set the WS755 up to take flow proportional samples, a flow monitor must be attached to the control panel. In this configuration, the sampler is designed to take a sample every time a specific amount of flow has passed through the flow monitor.

Page 15: Appendix A: Sample Size Vs. Head Height
Global Water Appendix A: Sample Size vs. Head Height Use the following graph to see how sample size changes with head height. The Sample Size controls on the control panel are calibrated at a height of 4 feet. Increasing the head height decreases the sample size by a predictable amount. -
Page 16: Appendix B: Battery Life
½ hour (5 gallons). To prevent large current surges which occur when the pumps first turn on, the WS755 is designed so that only one pump will turn on or off at a time. A ½ second time delay is inserted between these events, extending the life of the charge and the life of the battery. -
