ERLQ006~008BBV39

Outdoor unit for air to water heat pump

4PW68003-1A – 03.2011

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.

INSTALLATION

3.1.

Scope of the manual

This manual describes the procedures for handling, installing and
connecting 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 8

  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.

3.5.

Accessories

Check if the following accessories are included with the unit

Possible options

3.6.

Handling

As shown in the figure below, slowly move the unit by grabbing the
left and right grips.

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 8
