Unpacking And Placing The Unit; Refrigerant Piping - Daikin R-410A Installation Manual

Installation
Lift the unit with a crane and 2 belts of at least 27 ft. long.
•
When lifting the unit with a crane, always use protectors to
•
prevent belt damage and pay attention to the position of the
unit's center of gravity.
After installation, remove the transport clasps attached to
•
the large openings.
Bring the unit as close to its final installation position in its
•
original package to prevent damage during transport.
Refer to figure 3.

UNPACKING AND PLACING THE UNIT

Make sure the unit is installed level on a sufficiently strong
•
base to prevent vibration and noise.
Secure the unit to its base using foundation bolts. Use four
•
commercially available M12-type foundation bolts, nuts,
and washers.
The foundation bolts should be inserted
•
13/16".
Make sure the base under the unit
•
extends more than 30-1/8" behind the
unit.
The height of the base should be at least 5-7/8" from the
•
floor.
The unit must be installed on a solid longitudinal foundation
•
(steelbeam frame or concrete) as indicated in figure 4.
Refer to figure 4.

DO NOT USE STANDS TO SUPPORT THE
CORNERS
Refer to figure 5.
1. Do not use stands to support four corners.
2. Center position of unit.
3. Prepare a water drainage channel around the foundation
to condensate waste water from around the unit.
4. If the unit is to be installed on a roof, check the strength
of the roof and its drainage facilities first.
5. If the unit is to be installed on a frame, install the water-
proofing board within a distance of 5-7/8" under the unit
in order to prevent infiltration of water coming from under
the unit.
NOTE
1. Prepare a water drainage channel around the founda-
tion to condensate waste water from around the unit.
2. If the unit is to be installed on a roof, check the strength
of the roof and its drainage facilities first.
3. If the unit is to be installed on a frame, install the water-
proofing board within a distance of 5-7/8" under the

A (in.) B (in.)
48-13/16 43-3/8
unit in order to prevent infiltration of water coming from
under the unit.
When installing on a roof, make sure the roof floor is
4.
strong enough and be sure to water-proof all work.
Make sure the area around the machine drains properly
5.
by setting up drainage grooves around the foundation.
Condensate water is sometimes discharged from the
outdoor unit when it is running.
Block all gaps in the holes for passing out piping and wir-
6.
ing using sealing material (locally procured) to prevent
small animals from entering the equipment.

REFRIGERANT PIPING

NOTE
After completing installation, be sure to open the valves.
•
(See Section 6-6 Additional refrigerant charge. (Operat-
ing the unit with the valves shut will break the compressor.)
Add R-410A which comes in a pink cylinder.
All field piping must be installed by a licensed refrigeration
technician and must comply with relevant local and national
regulations.
CAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT
•
PIPING
Do not use flux when brazing copper-to copper refrigerant
piping, particularly for the HFC refrigerant piping. Instead
use the phosphor copper brazing filler metal (B-Cu93P-710/
795: ISO 3677) which does not require flux.
Flux has an extremely negative effect on refrigerant pip-
ing systems. For instance, if chlorine based flux is used, it
will cause pipe corrosion. Flux containing fluorine will
damage refrigerant oil.
Installation tools:
•
Make sure to use installation tools (gauge manifold charge
hose, etc.) that are exclusively used for R-410A installa-
tions to withstand the pressure and to prevent foreign mate-
rials (e.g. mineral oils such as SUNISO and moisture) from
mixing into the system.
The screw specifications differ for R-410A.
