This article walks you through the process of installing a DT-MK2P and WM4 alcolizer.

1. DT-MK2P

1.1. Specifications

1.2. GPO mounting location

1.3. Dimensions and installation layout

In our experience, electricians often cut and splice the COM cable (which should never be done, unless absolutely necessary). And if splicing and joining, this work must be carried out professionally, and all joins must be soldered and tested.

This is not a regular serial cable. It is an RS232 Null Modem COM Cable. The terminal and alcolizer will not communicate without this specific type of COM cable. If going down the splicing and joining path, only yellow, blue, and red wires are required.

1.4. Mounting height

The terminal itself is recommended to be mounted with the top of the unit 160cm – 170 cm from the ground. This height has been found to provide a usable interface and comfort factor for persons, covering the widest range of person’s heights. This is flexible and can be adjusted at sites discretion.

1.5. Mounting surface

A suitable location should:

• be out of the weather (rain, wind and sun)
• provide enough wall mounting space for all units to be mounted
• provide sufficient 3G mobile service where required
• be a suitable location for the workforce to find and access the system easily.

Consideration should be given to the ambient air temperature. If ambient temperatures exceed 50
degrees Celsius alternate locations should be found.

Warranty warning

Failure to mount out of sunlight or in weather affected areas will void all maintenance warranties and any cost of repair will be charged back to the client/site.

The unit can be mounted to most surface types; however, weight and usage needs to be considered for hollow-type walls. Suitable mounting components should be used to ensure a safe and secure installation. Typically, this may include the use of UniStrut or similar mounting systems.

On solid wall types (metal, brick, etc.), the units may be attached directly to the wall using suitable mounting methods.

1.6. Mounting the terminal 

The terminal attaches to the wall via 4 anchors, located in each corner of the unit. The holes for these anchors points are ONLY to be drilled as per Figure 5. 

Any holes required for conduit MUST only be drilled from the underside of the cabinet at the rear. This typically includes power and data cabling, as well as any cabling associated with an alcoliser if utilised.

Care should be taken that cables and conduits entering from the bottom rear of the enclosure do not affect the printer drawer operation. There is a 35 mm gap at the rear of the drawer to allow for conduits and cabling as shown in Figure 6.

Do not drill any additional holes in any other areas of the enclosure. Failure to comply with this will result in additional charges upon return of the equipment.

Mount the unit to the wall or mounting equipment using appropriate screws/bolts. Tighten and ensure the unit is stable and secure.

1.7. Clearance required

Adequate clearance is required if there is any other device installed in the same location e.g. alcoliser. The terminal door needs adequate clearance for it to be opened.

1.8. Reminders

• To open the cabinet, use the keys provided; ensure to lock it again after the installation is complete. 
• Make sure that all plugs inside the cabinet have power to them.
• As soon as power is turned on, everything will boot up automatically and the terminal will be ready to use in a few minutes.

2. WM4 alcolizer

2.1. Back plate

Use two-man lift procedures when mounting and removing from back plate. When the unit is open or not installed on the back plate, electrical components are exposed.

Ensure electrical power is isolated at the supply power point whenever the unit is open unless specifically required for special troubleshooting requirements.

2.2. Mounting the back plate

When choosing a suitable mounting location, the following factors should be considered:

• The instrument must be mounted on a wall or structure that can support the weight of the
  instrument. 
• The instrument must not be exposed to rain or water.
• The instrument should be mounted near to a mains power socket to allow for easy connection.
• Under extremely heavy use, the instrument could discharge excess saliva from a vent on the
  bottom of the main unit. Avoid mounting the instrument above anything that could be affected by moisture (e.g. power points).
• The instrument must not be exposed to extreme temperatures outside of the defined operating range.

2.3. Mounting height and position

The instrument must be mounted and positioned at a height to accommodate most users and in such a way to allow access to the key lock and to allow the machine to swing open.

Refer to Figure 8 for the appropriate mounting dimensions of the back-plate.

2.4. Mounting instructions

Mount the back plate in accordance with the following procedures:

1. Unpack and remove the instrument from the packaging.
2. Unlock the instrument and remove
   the back plate from the unit.
3. Choose a suitable mounting site as described previously.
4. Bend or remove any cutaway portions on the back plate to permit cable access if necessary
   (refer to Figure 9).

Do not use adhesives as the method of fixing as these are not considered to be a reliable or safe fixing means for the WM4.

5. Fix the back plate to the wall using masonry fixing hardware (e.g. medium duty anchors).

The fixings should be strong enough to support the instrument (at least 20kg) and any incidental loading such as a person leaning or pulling on the instrument.

2.5. Mounting the instrument

Mount the instrument in accordance with the following procedures:

1. Using an assistant, hang the instrument onto the back plate by aligning the male lift off hinge pins on the back plate with the main instrument lift of female hinge tubes.

2. Confirm the instrument swings effectively and does not impact any other fixtures.

3. Route any cables to avoid damage and trip hazards.

4. Visually check that there are no loose components from transportation.

5. Remove any packing materials.

6. Remove the screen protector film from the front of the display screen.

7. Load straws into the straw box, ensuring that the straws are lying freely within the box.

2.5. Starting the instrument

Perform the following steps for the initial start-up:

1. Turn the reference gas on by rotating the on/off valve one full turn anti-clockwise (refer to Figure 10).

2. Close and lock the instrument.
3. Plug the power cord into a power outlet and turn the power on.
4. Plug any other cords into their devices.

The instrument will take several minutes to start up and will take a further 10 minutes to perform its first self-calibration. After this, the instrument will be calibrated and ready for use.
