The Humiditherm, Envirotherm, Drying Ovens, Laboratory Ovens and Glassware Drying Ovens have a lever latch door handle that can be adjusted.
The lever latch doors from Thermoline can be adjusted at the strike to accommodate transport and floor level variations. See pictures of the lever latch in the closed position and the mechanism below.
If the latch feels overly tight or will not completely close the strike will likely need to be brought forward (away from the cabinet). Alternatively, if the latch feels loose when closed and it doesn't hold the door firmly closed the strike may need to be moved back (towards the cabinet).
The pictures above shows the strike. There is a philips head screw in the bottom that once loosened will allow you to move the strike forwards or backwards. There is a grooved surface that enables the screw to remain in position once tightened. Thermoline suggests making only very small changes to the strike location (one groove at a time) while making adjustments.
If this doesn't fix the issue please get in touch with the service department at Thermoline Scientific.
