This video demonstrates the step-by-step process to replace and adjust a door on your Harvest Right freeze dryer.
Replacing and Adjusting Your Door
Tools Needed:
- Open-ended 11mm wrench
- 5/32 allen wrench
Steps:
- Loosen the Locking Nuts: Start with the door closed and latched. Loosen the locking nuts found behind the hinge.
- Remove Lower Hinge Bolt: After loosing the locking nuts, remove the lower hinge bolt by turning it counterclockwise.
- Loosen the Upper Hinge Bolt: Whilst loosening the upper bolt, ensure to hold the door to prevent it from falling accidentally.
- Remove the Door: After successfully loosening the hinge bolts, simply pull the door away.
- Attach the New Door: The replacement door should have the hinge already attached. Hold the door close to the frame, insert the latch end into the latch handle for support, align and secure the top screw first, then the bottom one.
- Adjust the Hinge Studs: Start with about three turns just to get close. Aim to create contact at the nine o’clock position and a one-finger gap on the other side.
- Fine-tune Adjustment: As you adjust the upper and lower adjusting bolts, a line will begin to develop along the gasket surface. Try to achieve contact over most of the surface.
- Vacuum Test: Turn on the vacuum pump to see if the door is sucked in and the contact marks increase in size, indicating a good seal.
- Lock Down Adjustments: After a successful vacuum test, lock down the adjustments on the mounting bolts, turning the locking nut counterclockwise while holding the hinge bolt in place. Repeat the same for the bottom.
- Final Check: Finally, ensure your door is adjusted perfectly by checking if it opens smoothly. If you encounter any issues, reach out to tech support.
