DLFEHA: Installation Instructions

INSTALLATION TIPS

Ideal installation locations include:
Indoor Unit
• A location where there are no obstacles near inlet and outlet area.
• A location which can bear the weight of indoor unit.
• Do not install indoor units near a direct source of heat such as direct
sunlight or a heating appliance.
• A location which provides appropriate clearances (see Fig. 7.)

Prior to Installation
Before installing the indoor unit, ensure the compatibility with the
outdoor unit using the product data as a reference.
Select the Installation Location:
Before installing the indoor unit, choose an appropriate location.
The following are standards that should help you choose an appropriate
location for the unit. Proper installation locations must meet the following
standards:
1. Good air circulation
2. Convenient drainage
3. Noise from the unit will not disturb others
4. Firm and solid—the location will not vibrate
5. A site strong enough to support the weight of the unit
6. A location at least 3.28 ft. (1m) from all other electrical devices (e.g.,
TV, radio, computer)
7. DO NOT install the unit in the following locations:
a. Near any source of heat, steam, or combustible gas
b. Near flammable items such as curtains or clothing
c. Near any obstacle that might block air circulation
d. Near the doorway
e. In a location subject to direct sunlight
NOTE: Wall Holes: If there is no fixed refrigerant piping. While
choosing a location, you should leave ample room for a wall hole
(refer to the Drill wall hole for connective piping step) for the signal
cable and refrigerant piping that connect the indoor and outdoor
units. The default position for all piping is the right side of the indoor
unit (while facing the unit). However, the unit can accommodate
piping to both the left and right.
Attach the Mounting Plate to the Wall:
1. Carefully remove the mounting plate, which is attached to the back of
the indoor unit.
2. The mounting plate should be located horizontally and level on the
wall. All minimum spacings (see Fig. 7) should be maintained.
3. If the wall is block, brick, concrete or similar material, drill 0.2" (5 mm)
diameter holes and insert anchors for the appropriate mounting screws.
4. Attach the mounting plate to the wall.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
Mounting Plate Dimensions
Different model sizes have different mounting plates. Ensure there's
enough room to mount the indoor unit (refer to Fig. 3−6).
The following measurements can be located on these figures:
• Width of mounting plate
• Height of mounting plate
• Width of indoor unit relative to plate
• Height of indoor unit relative to plate
• Recommended position of wall hole (both to the left and right of
mounting plate)
• Relative distances between screw holes.

Refrigerant Line Routing
The refrigerant lines may be routed in any of the four directions (see Fig.
11).
For maximum serviceability, it is recommended to have refrigerant line
flare connections and the drain connections on the outside of the wall that
the fan coil can be mounted on. If the piping is going through the back:
1. Determine the pipe hole position using the mounting plate as a
template. Drill pipe hole diameter per values given in Figures 3−6. The
outside pipe hole is 1/2−in. (13 mm) min. lower than inside pipe hole,
so it slants slightly downward (see Fig. 11).

If piping is going through the right or left side:
1. Use a small saw blade to carefully remove the corresponding plastic
covering on side panel and drill the appropriate size hole where the pipe
is going through the wall.
