Mini-Clik Installation Instructions
In most installations, the Mini-Clik acts as a switch breaking the circuit to solenoid valves of an irrigation system when it rains. This allows the timer to advance as scheduled, but keeps the valves from opening allowing water to flow. Once the Mini-Clik has dried, the switch closes again to allow for normal operation.
Model Mini-Clik-HV(110VAC): This rain sensor unit is designed to be used with automatic irrigation systems of two principle designs:
1) single-station electrical timers that switch power to a pump, either directly or through a relay
2) single-station electrical timers that switch power to a solenoid valve
Standard Model: Using the screws provided, mount the Mini-Clik on any surface where it will be exposed to unobstructed rainfall, but not in the path of sprinkler spray. The switch-housing portion must be upright (as pictured), but the swivel-bracket can be moved for mounting on any angled surface. Loosen the locknut and screw before swiveling bracket, and then re-tighten.
For the Conduit Model Mini-Clik-C: The conduit acts as the mounting support for the unit. Therefore, place and mount the conduit to allow for the desired sensor location as described in the main instructions for the standard model. Be sure to support the conduit sufficiently along its various lengths.
For the High-Voltage Model Mini-Clik-HV: The mounting of this unit is primarily made by screwing the fitting end into the threaded holes of covers to rectangular junction boxes (for outdoor use) or the covers of round junction boxes commonly used for outdoor spotlights. Locate the junction box so that with the Mini-Clik attached, unobstructed rainfall will hit the outermost sensing end of the unit. If a longer reach is needed, the “Carlon” flexible conduit piece can be substituted with a slightly longer piece (up to 8ft/2.44m length with no support or up to 11ft//3.35m with support).
Helpful hints for mounting:
Once the Mini-Clik is mounted, run the wire to the controller, and fasten it every few feet with wire clips or staples for best results. If an extension to the wire provided is needed, use the following table to determine the minimum wire gauge needed:
Wiring to Your Irrigation System
The Standard Model Mini-Clik is sold and designed for hook up to 24V irrigation controllers only.
For the Model Mini-Clik-HV: WARNING! This unit must be installed by a qualified electrician in accordance with National Electrical Code and applicable local codes. The electrical rating of this device is 125-250VAC at 10.1 amps. Do not let current pass through this device that exceeds this rating.
All Mini-Clik models are listed by Underwriters Laboratories, Inc. (UL). Samples of these devices have been evaluated by UL and meet the applicable UL standards for safety.
