DCM 200 Installation

2.2.1.

Sample Connections

Modular Sensor Housing (DGMa)

• Mount white acrylic mounting plate within 60” of the DCM 200 controller, and allow at least 18”

clearance above the top of the mounting plate.

• Using the typical installation drawings on the following pages, connect sample tubing to the DGMa

modular sensor housing and the main recirculation lines, using the fittings supplied.

Note that the default mounting of the modular housing is to

flow from left to right.

• If preferred, the modular housing is reversible by

removing the assembled modules from the black upper

snap clips.

• First disconnect the spacer standoff brackets and pull

the module assembly to unsnap it from the upper clips.

• Once it is loose, simply flip the assembled modules so

that the molded arrows on the modules are pointing

right to left,

• Then reconnect it to the standoff brackets and remount

onto the backpanel.

• Next, use the typical installation drawing below as a

guide, and connect the sample supply and return

tubing using the selection of fittings supplied.

NOTE: Sensor Sample should always be from downstream of the filter, but up stream of the heater

and any chemical injection. Discharge sample into the line returning to the pool or spa as close to

the pool as possible to get the most pressure drop. Using the pressure drop created by other

devices like heaters or UV system works best.

CAUTION: Never take the sensor sample from unfiltered water as this may introduce hair or other debris into the

flow switch or sample cell. Never return sample to the suction side of the recirculation pump as this will cause a

negative pressure environment (vacuum) for the sensors, which will cause non-warranty damage to the sensors,

and more importantly, will cause erroneous readings and poor disinfection control.
