The Airrex Air Conditioner, models HSC-2500 and HSC-3500, is a portable cooling unit designed for various applications, including area/room cooling and targeted spot cooling for machinery, servers, or people. It operates on a 220-240Va.c., 60Hz, single-phase power supply, and users are advised to ensure their local electricity supply matches these specifications and that an appropriate plug is fitted by a qualified electrician.

Function Description:

The primary function of the Airrex Air Conditioner is to provide cooling. It offers both general area/room cooling, where it aims to reduce the temperature of an entire space, and spot cooling, which focuses on delivering targeted cooling to specific objects or areas. The unit features a flexible duct outlet for cold air, allowing for directed airflow. Hot air is exhausted through a separate condenser outlet. The cooling operation is controlled by a digital interface, which allows users to set the desired temperature and fan speed. The unit's compressor engages when the room/spot temperature is higher than the set temperature and disengages when it falls below.

• Temperature Unit Change: The temperature unit can be switched between Celsius (°C) and Fahrenheit (°F) by simultaneously pressing the up and down arrow buttons for three seconds.
• Cooling Modes: The "COOL" button selects the cooling mode. The unit also has "Low Mode" and "High Mode" buttons to control fan speed.
• Area/Room or Spot Cooling Selection: The display can show either "Room" temperature or "Spot" temperature. To display room temperature, the "COOL" and down arrow buttons must be pressed simultaneously for three seconds.
• Off Timer: An "OFF TIMER" function allows users to set a specific operating duration from 30 minutes up to 24 hours, in 30-minute increments up to 10 hours, and then 1-hour increments. The timer can be canceled by pressing the "Off Timer" button for one second.
• Remote Control: The unit can be controlled from a distance using a wired remote control.

• Storage: When not in use, the unit should be turned off, unplugged, and the power cable coiled neatly. It should be stored in a dry, cool place, suitably covered to prevent damage from damp, humidity, and dust.
• Condensate Tank: The unit has a condensed water tank to collect water generated during cooling, with a water level indicator to check its status. The compressor automatically shuts off when the tank is full.
• Safety Precautions: The manual emphasizes the importance of using the correct power supply, securely plugging into an earthed supply, not using damaged cables, and unplugging before cleaning. It also advises against placing objects on top of the machine, using unapproved extension leads, or operating on unstable surfaces.
