LC DX Interface
Installation Manual
3 INSTALLATION
Use the following information to specify the appropriate AHU and DX Coil for each
outdoor unit. The DX Coil design should be optimised for Cooling (Rated) Condition:-
• The DX Coil must be suitable for R410A.
• The counter flow principle must be observed.
• The design should allow operation as both an Evaporator and a Condenser
• (Features: Multiple circuits / Liquid Capillary Distributor / Gas Header).
• A Drain Pan must be fitted (even if only used in Heat mode) due to defrost cycles.
• It is recommended to fit droplet eliminator plates in the discharge air stream if
used in Cool mode.
• The sensor holders must be brazed on to DX coil to ensure accurate temperature sensing.
• Cooling (Rated): Saturated Suction Temp. (Evaporating Temp.): 7°C
• Heating (Rated): Saturated Discharge Temp. (Condensing Temp.): 44°C
• Target Suction Super Heat: 5K
• System Maximum Operating Pressure: 4.15MPa
• DX Coil must satisfy Burst Pressure: More than 12.45MPa (3 times Maximum Operating Pressure)

• The standard air volume flowrate is a guideline. Required capacity should be used for system matching.
• AHU fan motor must be interlocked to fan control output.
• Maximum DX-Coil U-pipe Outer Diameter: 12.7mm (1/2”)
• Recommended DX-Coil U-pipe Outer Diameter: 9.52mm (3/8”)
• Cooling & Heating output figures are based on calculations and ‘general’ test data. All figures are to be taken as approximations.
The properties of the third party DX Coil will have an affect on the performance of the outdoor units. All capacity data shown is
based on the following Rated Conditions: -
o Cooling (Rated): Indoor air temperature 27°C db / 19°C wb, Outdoor air temperature 35°C db
o Heating (Rated): Indoor air temperature 20°C db, Outdoor air temperature 7°C db / 6°C wb
