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

Performance figures derived from independent testing by UK test houses BRE and BSRIA in accordance with
test standard EN 14511.
The air curtain normally operates under automatic temperature control and can also run at part load.
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.

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, suitable pipe reducers must be used for the
connection. R410a refrigerant systems can operate at pressures up to 610 psi (c. 42
Bar). These brazed joints may well be located in a public area and a weakness leading
to an explosion could be extremely dangerous. The air curtain with its coil is
