What is R134a Refrigerant?
R134a refers to the refrigerant gas used in chiller/air condition compressors.
It is a common refrigerant that is used in many air conditioning applications.

Due to the nature of R134a properties which is of a HFC (hydrofluorocarbon) refrigerant, it does not have any ozone depletion potential and has little greenhouse effect. 

Directions for Use:

• During/after transporting and/or fixing up the chiller, allow it to stand upright for at least 3-6 hours before powering it up. This reduces unnecessary damage by allowing the oil and fluid to flow back into the compressor.
• Do not place the chiller outdoors or near any heat source.
• Do not place the chiller in enclosed cabinets.
• Place the chiller approximately 30cm away from walls to facilitate ventilation.
• Do not cover the chiller while it is in operation as this will cause over-heating.
• For use with marine setups, it is recommended to install the chiller after the filtration systems. This is to ensure the durability and function of the evaporator.
• Regular maintenance of the circulating systems, front draft hood and air filters are advised at once every month.
• For troubleshooting of issues such as not being able to power on the unit, faulty powering issues, lack of refrigeration, or loud noises / vibration from the unit. Please refer to the instructions booklet for suggestions on basic problem solving.

*When moving the chiller, always transport the chiller upright.

*After transport, and fixing up the chiller, allow it to sit for at least 3-6 hours before powering it up. This will allow the oil and fluid to flow back into the compressor and reduce chances of unnecessary damage.
