EFORE INSTALLATION
Precautions
■
The new 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 the chapter ‘Precautions on refrigerant piping’ carefully
and follow these procedures correctly.
Since design pressure is 3.3 MPa or 33 bar, pipes of larger wall
thickness may be required.
■
Since R407C 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 units must be indoor units designed
exclusively for R407C. If indoor units for R22 are connected,
normal operation cannot be assured.
Installation
■
For installation of the indoor unit(s), refer to the indoor unit
installation manual.
■
This outdoor unit requires the pipe branching kit (optional) when
used as the outdoor unit for the simultaneous operation system.
Refer to catalogues for details.
■
Never operate the unit without the thermistor (R3T), burning of
the compressor may result.
■
When closing the service panels, take care that the tightening
torque does not exceed 4.1 N•m.
Accessories
Check if the following accessories (gas pipes) are included with your
unit.
Handling
The units are packed in a wooden crate and attached on a wooden
pallet.
At delivery, the package should be checked and any damage should
be reported immediately to the carrier claims agent.
When handling the unit, take into account the following:
1. Fragile, handle the unit with care.
Keep the unit upright in order to avoid compressor damage.
2. Lift the unit preferably with a crane and 2 belts (1) of at least 8 m
long.
3. When lifting the unit with a crane, always use protectors (2) to
prevent belt damage and pay attention to the position of the unit’s
centre of gravity.
4. Bring the unit as close to its final installation position in its original
package to prevent damage during transport.
