Mitsubishi Electric Outdoor Unit
The Mitsubishi Electric Mr Slim Outdoor Unit is selected to match its refrigerant heat
output to the size of the Air Curtain. See Table 2 below for size of outdoor unit to be
used together with performance data for the air curtain.

Outputs based on:- Indoor air temperature = 20ºC. Outdoor condition = 7/6 db/wb ºC for heating output,
35/27 db/wb ºC for cooling output.
Performance figures derived from independent testing by UK test houses BRE and BSRIA in accordance with
test standard EN14511. Noise testing carried out at Sound Research Laboratories to ISO27327-2, ISO3741 and
BS4856-4.
See Table 4 for more details of air volume flow rates and noise levels. (HX2-M units have TORIN EC Fans)
* Alternative larger outdoor unit will give enhanced heat output for difficult doorway situations - not
recommended, however, for weather compensation control or discharge air temperature control.
Refrigerant Pipework
This must be carried out before connection of any electrical and controls cables
and in accordance with the Instructions that come with the Mitsubishi Electric
Outdoor Unit. This work must only be undertaken by a Mitsubishi Electric
approved Contractor.
Contact Mitsubishi Electric for recommended pipework sizes, pipework lengths,
numbers of fittings, etc.
The installation must be carried out in accordance with the Mitsubishi Electric
Installation Manual that comes with the outdoor unit.
It is intended that refrigerant pipe connections to the air curtain are made using brazed
joints and these must be carried out in a professional and safe manner. If installation
pipe sizes for the discharge (gas) line and liquid line are different from the pipe
connection sizes on the air curtain (see Figure 2) suitable pipe reducers must be used
for the connection. R410A refrigerant systems can operate at pressures up to 610 psi
