Abstract

In an embodiment of the present disclosure, a condensate level switch mounting assembly includes a condensate level switch having a mounting frame, a first bracket configured to fixedly attach to a condensate drain pan, and a second bracket having a mounting plate configured to engage with the mounting frame of the condensate level switch to secure the condensate level switch to the second bracket. The condensate level switch mounting assembly further includes a fastener assembly configured to couple the second bracket to the first bracket such that an angular position of the second bracket is adjustable relative to the first bracket.

First claim

The invention claimed is:

1. A heating, ventilation, and/or air conditioning (HVAC) assembly, comprising:
a drain pan comprising a receptacle configured to collect condensate in an HVAC system, wherein the receptacle comprises a depth;
a mounting frame of a liquid level sensor;
a mounting assembly configured to couple to the drain pan and to support the liquid level sensor adjacent to the drain pan via the mounting frame of the liquid level sensor;
a first bracket of the mounting assembly configured to be mounted to the drain pan; and
a second bracket of the mounting assembly comprising a mounting plate, wherein the mounting frame of the liquid level sensor is configured to capture the mounting plate of the second bracket, wherein the second bracket is configured to couple to the first bracket such that a position of the second bracket relative to the first bracket is adjustable between a plurality of orientations, wherein the second bracket is rotatable relative to the first bracket and about an axis extending crosswise to the depth of the receptacle, and wherein the mounting plate extends along the depth of the receptacle.

2. The HVAC assembly of claim 1 , wherein the first bracket has a first aperture, the second bracket has a second aperture, and the mounting assembly has a fastener configured to extend through the first aperture and the second aperture along the axis to fasten the first bracket to the second bracket.

3. The HVAC assembly of claim 2 , wherein the first aperture is a slot, and wherein the second bracket and the fastener are configured to conjunctively move linearly along the slot to adjust the position of the second bracket relative to the first bracket.

4. The HVAC assembly of claim 2 , wherein the second bracket is configured to be rotated about the fastener and the second aperture to adjust the position of the second bracket relative to the first bracket.

5. The HVAC assembly of claim 1 , wherein the first bracket comprises:
a mounting flange configured to mount to the drain pan; and
a positioning flange extending from the mounting flange and configured to couple to the second bracket, wherein the positioning flange comprises a slot, and the mounting assembly comprises a fastener assembly engaged with the slot and the second bracket to facilitate linear and rotational adjustment of the second bracket relative to the first bracket.

6. The HVAC assembly of claim 5 , wherein the positioning flange comprises linear measurement indicators positioned on a surface of the positioning flange adjacent to and along a length of the slot.

7. The HVAC assembly of claim 5 , wherein the mounting flange comprises a plurality of mounting receptacles configured to receive respective fasteners to fixedly attach the first bracket to the drain pan.

8. The HVAC assembly of claim 5 , wherein the second bracket comprises a rotational flange extending from the mounting plate, wherein the rotational flange comprises an aperture, and wherein the fastener assembly extends through the aperture and through the slot to couple the second bracket to the first bracket.

9. The HVAC assembly of claim 8 , wherein the rotational flange comprises angular measurement indicators positioned on a surface of the rotational flange adjacent a circumference of the aperture.

10. The HVAC assembly of claim 8 , wherein the rotational flange is offset from a center of the mounting plate relative to a length of the mounting plate.

11. The HVAC assembly of claim 8 , wherein the fastener assembly comprises:
a bolt extending through the aperture and the slot; and
a nut configured to couple to the bolt to secure the second bracket at the position relative to the first bracket and in an orientation of the plurality of orientations.
