AGS WTM Installation, Operation & Maintenance

Installation

Typical Application & Location

The AGS Water Temperature Monitor (WTM) is carefully designed for health care facilities to monitor and

control the water supply system. The controller incorporates a simple user interface to reset and/or silence

alarm condition. Minimum and Maximum permitted water temperatures are configurable via the internal

switch and fascia controls upon installation.

Located and installed in positions determined by those who have knowledge of the process plant system

and equipment involved, and in consultation with both safety and electrical engineering personnel.

The monitor should be installed in the correct orientation, as recommended by the manufacturer at a height

to suit access and status observation and is designed for indoor operation only.

Mounting & Cabling

If mounting direct to wall - ensure the wall surface is flat to prevent base distortion.

Where suitable cable glands/conduits are used for wire entry, use 20mm (3/4 inch) max.

Restrain the hazardous live wiring from accidental loosening to prevent wires from moving after

installation and touching parts of opposite polarity or at low voltages.

A switch or circuit breaker must be fitted, it must be accessible and marked as the disconnecting device.

Isolate the equipment from all hazardous live power sources before opening the cover.

Carefully remove the front cover from the unit by using an M3 socket wrench.

Using the rear base - mark mounting holes to the wall or align with an appropriate gang/pattress box.

Fixing straight to wall – drill 0.2" (5mm) hole, insert plugs and use the four screws (No.4 Pozi) provided.

Alternatively – Fix direct to a vertical 2-gang/double electrical pattress box.

There are pre-fractured areas for cable entry on the rear of the base and pilot holes positioned on the top

and bottom of the enclosure suitable for entry points up to ¾" (20mm). Drill out as necessary ensuring all

swarf is removed from the box and holes have smooth edges.

Secure the front cover with all M4 bolts and insert security caps provided.
