SECTION 5 INSTALLATION
5.1 Unpacking the Instrument
When removing the instruments from their shipping containers, inspect all units for any
damage that may have occurred during shipment. The containers include the EC1000
Controller, Pump Module, Electrode, Instruction Manual, installation kits for the
Controller and Pump Module, Pump Module maintenance kit, and electrolyte
(see REPLACEMENT PARTS on page 109). If damage is evident, or if the shipment is
incomplete, customers outside the U.S.A. should contact their local Hach Distributor.
Customers inside the U.S.A. should contact Customer Service in Loveland, Colorado.
Call toll-free 1-800-227-4224.
5.2 Industrial Process pH Electrode Preparation
Remove the electrode from the box and carefully remove the tape and protective cap from
the sensing end. Retain the protective cap for electrode storage. If salt crystals are present,
remove them by placing the sensing end of the electrode under a current of warm tap water
until the crystals dissolve. Keep the quick disconnect fitting dry. It is important to avoid
touching the internal area of the quick disconnect fitting. Contamination, such as oils and
salts from bare hands, can form a leakage path affecting the high impedance required
between the electrode and the controller.
5.3 Mounting the Controller
The controller is designed for panel, wall or pole mounting. All methods use a Mounting
Bracket (Cat. No. 43646-00). For dimensions and other mounting information see
Figure 12 on page 58 and Figure 13 on page 59.
5.3.1 Panel Mounting
Cut the panel before inserting the meter. The panel cutout is to be 5.50"x 5.50"
±
0.05". For
panel mounting, remove the two mounting brackets, insert the meter into the panel, and
reattach the mounting brackets. See Figure 12 on page 58. Insert screws
(Cat. No. 5617-11) through mounting bracket inserts, and adjust for panel thickness.
