INSTALLATION

Safety and Preliminary Checks

Observe the following safety and preliminary checks before and during each installation:

¥ Verify that you are at the location specified on the Site Work Order.

¥ Verify that the site is safe for you and your equipment.

¥ Notify the customer of your presence and tell the customer that you will need access to the

water meter.

¥ If the Site Work Order does not have an MIU ID number on it, write in the ID number of

the MIU you are about to install. If the Site Work Order already has a MIU ID number on it,

verify that it matches the ID number on the MIU you are about to install.

Note: ¥ Always follow your companyÕs safety practices and installation guidelines when

installing an MIU.

¥ Never perform an installation during a lightning storm or under

excessively wet conditions.

¥ Use only approved climbing equipment.

Site Selection

The Wall MIU1 should be installed and operated in an environment where the temperature

stays between -22¡ and 149¡F (-30¡ and 65¡C). Installation and operation in moderate

temperatures increases reliability and product life.

Follow these guidelines when selecting a location to install the Wall

MIU1:

¥ For best results, Schlumberger recommends mounting the MIU on the outside of the building

and in a location that provides a direct line-of-sight to the path of the meter reading device.

¥ For best results, Schlumberger recommends, the MIU be installed approximately five feet

above the ground.

¥ The MIU must be installed in a vertical and upright position.

¥ The preferred mounting surface for the MIU is a flat wall, but it can also be mounted to a

pipe.

¥ The selected location should be clear of all obstructions.

¥ Avoid installing the MIU behind metal fences or walls.

. RF line of sight must be verified to a nearby MCC for data strength.

¥ The maximum cable length between the encoder register and MIU depends on the registerÕs

manufacturer and model. Refer to Table 2.3 for maximum

cable lengths.
