5.5 Removing the Top Section
De-energize all potential sources of energy to
this unit and lockout/tagout their controls.
(O.S.H.A. Regulation, Section 1910-147.)
If it becomes necessary to remove the top of the incubator when moving it through
low doorways, use the following procedure:
•
Read the instructions completely before starting the removal process.
•
Provide adequate space and sufficient lighting to perform the work.
•
Disconnect the inlet water supply and the drain.
•
Before lifting the top section from the incubator, provide sawhorses or another
suitable support arrangement so that the underside of the top is suspended.
Procedure:
1. Remove all test material from the incubator chamber.
2. All temperature and/or humidity sensing probes are mounted on a probe mounting
bracket on the right side of the incubator chamber. Remove the nuts securing the
bracket and then remove the probes from the bracket. Note the location and
configuration of the probes.
3. The sensing bulb capillaries are routed behind the duct sheet up to the access port at
the top of the unit behind the control panel. Route all of the probes between the duct
sheet and the outside wall of the chamber so that when the top is raised, the probes
will move freely up and out. Do not kink or bend the capillaries.
4. The humidification system drain line (3/8" clear Tygon) is routed down through the
access port and is secured to the condensate drain tube on the center left side of the
incubator, as viewed from the rear. Free the drain line, by pulling it away from the
float tank (behind the control panel) and routing it down through the access port.
5. Open the control panel by removing the two screws located on the left side of the
control panel.
