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. AC = with AC Fans, EC = with EC Fans
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 ISO3741 and BS4856-4.
See Table 4-5 on Page 25-26 for more details of air volume flow rates and noise levels.
P71, P125 and P140 Index air curtains have the LEV fitted inside of the air curtain.
* VRF HP2000 DXE P140 with EC Fans has low outlet air temperature at High Speed – not for normal use.
** VRF HP2000 DXE(HO) P200 air curtain has a twin LEV kit that is fitted into the liquid line pipework on site.
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
City Multi system. 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 compressor unit and with reference to the Index
Size of the air curtain (indoor 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 1, Page 11), 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 manufactured in accordance with the Pressure Equipment
Directive (PED) and the installation must be carried out to a good standard of
workmanship. Remove the protective plastic film on top of the air curtain before starting
work and protect the top surface of the air curtain. Use a heat sink on the copper pipes
during brazing to reduce the transfer of heat to the inside of the air curtain where
