Conduct Test RunsUpdated 2 hours ago

Introduction

This article explains how to conduct and complete a test run for our systems.

Perform the test run after the entire system has been completely installed. 

Before the Test Run

Confirm the following: 

• The indoor and outdoor units are properly installed. 
• The piping is properly connected.
• The wiring is connected correctly, and the unit's electrical system is safe and operating properly.
• The grounding wires are properly connected. Measure the grounding resistance using a grounding resistance tester. The grounding resistance must be lower than 4Ω. 
• There are no obstacles near the unit's inlet or outlet, as these could cause poor performance or product malfunction. 
• The flare nut connections were completed correctly, and the refrigeration system is leak-free. If a gas leak is suspected, read this article to learn how to find it. 
• The gas and liquid valves (high/low) are fully opened. 
• The drainage system is unobstructed and directs condensate to a safe area. 
• The heating insulation is properly installed. 
• The piping length and additional refrigerant capacity have been recorded. 
• The power voltage is correct for the air conditioner.

Perform the Test Run

1. Open the liquid and gas stop valves. 

2. Connect power to the system and allow it to warm up. 

3. Ensure the system operates in Heating and Cooling mode. Allow the system run in each mode for 5 minutes. 

Note: If outdoor temperatures are too high to set the system to Heating mode during the test run, turn on the system and use the emergency button to activate it. Once the test is complete, use the emergency button again to turn the system off.

4. Ensure the following for the indoor unit: 

• The remote controller and its buttons operate properly. 
• The indicators on the remote control and the indoor unit's display panel are working properly. 
• The louvers move properly and can be changed using the remote control. 
• The indoor unit's manual buttons operate properly. 
• The room temperature is being registered correctly. 
• The drainage system is unobstructed and directs condensate to a safe area.
• No vibration or abnormal noise is present during operation.

5. Ensure the following for the outdoor unit: 

• The refrigeration system is not leaking. 
• No vibration or abnormal noise is present during operation.
• Wind and water generated by the unit does not disturb others or pose a safety hazard.

After the Test Run

Once the test run is complete, return the system to a normal desired operating temperature. 

Use insulation tape to wrap any indoor refrigerant pipe connections that were left uncovered during installation.
