Keeprite indoor unit frequently shuts off due to a float switch or safety device; water present in secondary drain pan.

Safety first: Turn off power to the indoor unit before working near water and wiring.

• Step 1 – Locate float switch: Identify the float switch on the primary drain line or secondary pan and gently lift it to confirm it shuts the system off.
• Step 2 – Clear primary drain: Use a wet/dry vacuum at the outside drain termination to remove clogs. Flush with water and a small amount of bleach.
• Step 3 – Empty secondary pan: Remove water from the secondary pan and dry it. The presence of water indicates the primary drain is not working correctly.
• Step 4 – Test operation: Reset the float switch and run the system, monitoring for proper drainage.
