■
For use of units in applications with temperature alarm settings it
is advised to foresee a delay of 10 minutes for signalling the
alarm in case the alarm temperature is exceeded. The unit may
stop for several minutes during normal operation for "defrosting
the unit", or when in "thermostat stop" operation.
■
Tighten the flare nut according to the specified method such as
with a torque wrench.
If the flare nut is tightened too hard, the flare nut may crack after
a long time and cause refrigerant leakage.

EFORE INSTALLATION
3.1. Scope of the manual
This manual describes the procedures for handling, installing and
connecting ERHQ and ERLQ units. This manual has been prepared
to ensure adequate maintenance of the unit, and it will provide help if
problems occur.
3.2. Precautions for R410A
■
The refrigerant requires strict cautions for keeping the system
clean, dry and tight.
-
Clean and dry
Foreign materials (including mineral oils or moisture) should be
prevented from getting mixed into the system.
-
Tight
Read "9. Precautions on refrigerant piping" on page 9 carefully
and follow these procedures correctly.
■
Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state. (If the refrigerant is
in state of gas, its composition changes and the system will not
work properly).
■
The connected indoor unit must be the EKHBH/X008 unit
designed exclusively for R410A.
3.3. Installation
■
For installation of the indoor unit, refer to the indoor unit
installation manual.
■
Never operate the unit without the thermistors, burning of the
compressor may result.
■
Be sure to confirm the model name and the serial no. of the
outer (front) plates when attaching/detaching the plates to avoid
mistakes.
■
When closing the service panels, take care that the tightening
torque does not exceed 4.1 N•m.
3.4. Model identification
ERLQ units include special equipment (insulation, bottom plate
heater,...) to ensure good operation in areas where low ambient
temperature can occur together with high humidity conditions. In such
conditions the ERHQ models may experience problems with severe
ice build up on the aircooled coil. In case such conditions are
expected, the ERLQ must be installed instead. These models contain
countermeasures (insulation, bottom plate heater,...) to prevent
freeze up.
3.5. Accessories
■
Check if the following accessories are included with the unit
■
Possible options
Optional bottom plate heater
WARNING
Since maximum working pressure for this outdoor unit is
4.17 MPa or 41.7 bar, pipes of larger wall thickness may be
required. Refer to paragraph
"8.1. Selection of piping
material" on page 9 .

INFORMATION
■
An ERLQ0* BA/BB outdoor unit can only be
connected to an EKHBH/X008 BA/BB indoor unit
(bottom plate heater at outdoor unit has to be
controlled by indoor unit).
■
An ERHQ0* BA/BB outdoor unit can be connected to
an EKHBH/X008 BA/BB indoor unit or to an EKHBH/
X008 AA indoor unit (if a bottom plate heater kit is
required, see "Possible options" on page 4 ).
