Lab: Assembly Guide

Posted on by atmizoo

From time-to-time, it might be necessary to disassemble your Lab in order to perform maintenance tasks, install custom / replacement parts or swap between different bottom cap contact modes. The disassembly / reassembly procedure of all parts is quick and straightforward – however, it should be carried out carefully, mainly due to the small size of certain components, which can be easily misplaced or damaged.

1. Switch Disassembly

The Switch Assembly contains all switch components and is removable and 100% rebuildable. To remove the Switch Assembly from the mod, follow these steps:

  1. Remove the Button from its Axle.The easiest way to do this is by gently lifting the button from the axle by using a tea-spoon or coin. First, slightly lift the top-side of the button closer to the 510 connector, and then, do the same for the opposite side of the button. Repeat carefully until the button pops out.

    Removing the button will expose: a) the top of the Switch Axle, where the button is mounted, and b) a black delrin Washer.

  2. Remove the exposed delrin Washer from the External Switch Housing.The easiest way to do this is to gently pull the washer out the hole with a pair of tweezers, a small screwdriver, or other similar object. Insert the tweezers’ tip deep into the exposed hole and progressively lift the washer from below by applying the same side-to-side technique you used to remove the button in Step 1.

    If you maintain the switch on a regular basis, you may find it easier not to install the delrin Button Washer at all. This part is entirely optional and only helps keep some dust out of the switch.

  3. Un-screw the 510 Connector and remove the Switch Assembly from the External Switch Housing.If you haven’t done so yet, remove 510 Connector with the help of a coin. To remove the Switch Assembly, you will need to push the switch assembly though the battery compartment with the back of pen, while keeping the Axle pressed down. Push firmly but slowly from the back, until the switch assembly gets loose. Then, press the Axle a bit and slide the switch out.

    Important: The switch is designed so that the Axle will stay in place when the switch is removed. However, you still need to be careful not to lose any springs or ball bearings as you remove the switch from the mod.

  4. Take out the Axle and remove both Contact Pins from the delrin Housing.To avoid any damage to the delrin housing or Contact Pins, they should be pushed outwards from inside. Simply insert any non-sharp object in the Axle hole and use it to gently push out the Contact Pins. The atomizer Contact Pin should always be the easiest to remove, so always remove that first. If the battery-side one is giving you trouble, it is easier to remove it by pushing it through the atomizer pin hex hole.
  5. Identify all Switch Assembly components.With the Switch Assembly removed from the External Switch Housing, the disassembly is complete. All components included the switch of your Roller / Dingo can be easily located and identified.

2. Switch Assembly

The re-assembly process is very straightforward. The sequence of steps is similar to the disassembly process, moving from the last to the first step.

When tightening the connector, remember that it might be necessary to back off a bit at the end in order to keep the button perfectly aligned.

3. Switch Components Identification

The Switch Assembly consists of the following parts:

  1. An Internal Switch Housing. Its primary role is to hold together the moving and fixed contacts of the double-break switch. A 14×1.00mm o-ring is mounted around the top section of the housing to isolate the battery compartment from the switch even when the connector is removed.
  2. A moving Axle with a 4mm Spring. The Axle is inserted in the center of the Internal Switch Housing, with the 4mm Spring mounted on its bottom.
  3. A silver-plated Contact Rod. This is the moving contact of the switch and is inserted in the middle of the switch Axle.
  4. A 2mm Ball-Bearing and tiny 2mm diameter Spring. Both are inserted in the 2mm hole on the head of the switch Axle.
  5. A hexagonal, silver-plated Battery Contact. This is inserted in the battery-side slot of the Internal Switch Housing.
  6. A large, hexagonal Atomizer Contact, liquid-sealed and silver-plated. This is inserted in the atomizer-side slot of the Internal Switch Housing. The pin’s height is tuned by adjusting the position of the screw mounted on its top. This contact has a 10×1.5mm o-ring sleeved around it, which completely seals the internal of the switch from any juice leaked from the atomizer.
  7. A robust 304 SS pole screw.
  8. A Pole Insulation Cap. This is mounted on the Atomizer Contact to electrically isolate the positive pole of the mod from the negative pole of the atomizer under all circumstances.

The Contact Rod, Ball-Bearing, and 2mm / 4mm Springs require no disassembly and can be easily removed from the Axle once it has been lifted out of the Internal Switch Housing.

The hexagonal Contact Pins can be easily pushed out of the delrin housing after the Axle has been removed. To remove the hex Contacts, simply push the contacts outwards.

4. Bottom Cap Disassembly

Springless-Fused Mode

In Springless-Fused mode, the delrin Cap Housing holds together a flat-bottom Fuse-to-Battery Contact and a PTC Fuse. The Fuse is simply sandwiched between i) the Fuse-to-Battery Contact, and ii) the Cap.

To disassemble the Cap components, insert a small screwdriver into the silver-plated Battery Contact and simply lift the Battery Contact and delrin Housing out of the Bottom Cap. The assembly will simply pop out.

Springless-Direct Mode

In Springless-Direct mode, the delrin Cap Housing holds only a Direct Cap-to-Battery Contact, which can be found in the box of your Lab.

Note that the Fuse-to-Battery Contact used in Springless-Fused Mode has a flat bottom and is shorter than the Direct Battery Contact used in Springless-Direct Mode.

To disassemble the Cap components, insert a small screwdriver into the vent hole of the silver-plated Battery Contact (Fused or Direct) and simply lift the whole assembly out of the Bottom Cap.

5. Bottom Cap Assembly

Springless-Fused Mode

When assembling the Cap in Springless-Fused mode, it is important to take care so that the Fuse edges do not get damaged or compressed. The easiest way to complete the assembly successfully is this:

  1. Hold the delrin Cap Housing upside down and press the Fuse-to-Battery Contact in it.
  2. Carefully place the Fuse on top, ensuring that all edges of the Fuse are sitting inside the delrin Housing.
  3. Finally, take the Bottom Cap, hold it upside-down and press it carefully and slowly onto the Housing-Contact-Fuse assembly.

This process will be made a lot easier if you place the Housing-Contact-Fuse assembly over the 510 connector of the device (or any other flat surface with a ~8-12mm hole) and then carefully complete the assembly by pressing the Cap on it.

Springless-Direct Mode

To assemble the Cap in Springless-Direct mode, simply install the Direct Contact into the delrin Housing and then carefully press the 2 assembled parts into the Bottom Cap.
