Hyundai HY3100P 100L Electric Air Compressor | A Maintenance & Troubleshooting Guide

⚠️ PLEASE NOTE: You must read and understand the your HY3100P's operating manual before operating or undertaking any maintenance.

The HY3100P is a powerful 3hp twin cylinder air compressor ideal for spray-painting, air tools, inflating tyres, and perfect for workshops and garages.

To help ensure that your HY3100P is kept in optimal condition, we've detailed some tips for maintenance and troubleshooting below.

⚠️ WARNING: DO NOT tamper with or attempt to adjust the pressure switch or safety valve. Before moving or carrying out any maintenance on the compressor, make sure that the ignition switch is in the OFF position, the power cord has been unplugged and the air tank pressure has been vented and the compressor allowed to cool down for a period of time.

MAINTENANCE

• DRAINING THE TANK

Draining the tank reduces the risk of corrosion inside the tank; you should drain the tank at the end of each day. First, place a suitable container (capable of holding water) underneath the compressor. 

Next, with compressed air in the tank, slowly turn the drain knob to the open position, allowing any water in the tank to drain out. Once the water has drained, turn the drain knob back to the closed position.

• AIR FILTER

The air filter is designed to reduce noise and help prevent particulates in the air, from entering and damaging the air compressor. After being used for a period of time, the air filter will become clogged, reducing the air intake capabilities of the compressor, and overall performance. As such, it is essential that the air filter is cleaned or replaced regularly.

Open the cover of the air filter and remove the air filter element; inspect the filter element and, if damaged or worn, replace immediately. Replacement air filters are available via our dedicated spare parts website: Power Spares.

To clean the element, blow the dirt from the air filter from the inside out; you can use a low pressure airline to do this. Once cleaned, reinstall the air filter.

• LEAK TESTING

Any leaks in the housing or connection will reduce your air compressor's performance. A simple test for leakage is to spray a small amount of soapy water on the area suspected of leaking. If soap bubbles appear, minor leaks can be addressed with PTFE or thread seal tape as a short term measure; alternatively, the compromised component(s) should be replaced.   

• CLEANING

The HY3100P can be easily cleaned with a simple moist cloth or soft brush.

⚠️ DO NOT use a pressure washer or hose pipe, as water can penetrate the motor and cause failure that will not be covered by the warranty. 

⚠️ DO NOT use solvent based cleaning products, as these can cause damage to parts.

• STORAGE

When storing your HY3100P for extended periods, turn of the power and wrap the power cord around the compressor itself. Next, pull the the relief valve and release all the pressure from the air tank. 

Clean the air compressor to remove any dirt and dust, and then box or cover the unit to protect it from any dust or moisture whilst in storage. 

⚠️ DO NOT stack or store other items on top of or around the air compressor.
