IVF CUBE – Gas Port Adjustment Procedure

In order to change the gas port location, you will need to prepare following tools:

1. Adjusting plate (see picture 1 below)

2. Phillips screwdriver (Bar length should be about 40cm or longer)

Picture 1 – Adjusting plate

Adjusting plate is designed to fit completely to the heating stage of each drawer. Replace the

hand-held chamber to the plate when you need to adjust port position.

Port position changes by the production date, and rectangle piece with 3 drilled holes needs

to be adjusted according to the unit’s port position. For the units which serial number is 10 or

less, fix the rectangle piece to the plate using the middle 2 screw threads. For the units

which serial number is 11 or greater, fix the rectangle piece to the plate using the screw

thread on each side.

Serial Number: 1 to 10 Serial Number: 11 and greater

Gas ports are fixed with phillips head screws at each side. Before starting the adjustment,

loosen these screws a few revolutions counterclockwise and let the gas ports move up and

down smoothly. Do not loosen too much or remove these screws.

While the adjusting plate is placed on the drawer, slowly close the drawer until you can

compare the port position and drilled hole position difference.

Loosen these screws by 2 or 3 revolutions

counterclockwise.

Adjust the port position using the phillips screwdriver and when its position completely gets

into line, close the drawer all the way back to its close position and turn the drawer knob to

the horizontal position to keep it closed.

While the drawer is closed, tighten the 2 screws that hold gas port completely. After this

procedure try opening and closing the drawer several times without removing the adjusting

plate and confirm any port is not getting stuck at any of the drilled hole.
