Installation Manual for Snow Protection Hood (for Outdoor Unit)
IMPORTANT NOTICE:
: Indicates a hazardous situation that, if not avoided,
could result in death or serious injury.
: Indicates a hazardous situation that, if not avoided,
could result in minor or moderate injury.
1. Applicable Unit
NOTE:
The applicable outdoor unit may be different depending on the product series. Be sure to confirm with
the product catalogue before installation.
This snow protection hood prevents snow from entering the outdoor unit and prevents a strong wind from
blowing against the heat exchanger. Be sure to read this manual carefully for correct performance before
installation work.

2. Installation Work
(1) After the snow protection hood is installed, electromagnetic noise at the air outlet side may slightly
increase. Therefore, it is necessary to carefully consider the air discharge direction when installed.
(2) Be sure to tighten the snow protection hood securely to the top panel and side panel of the outdoor
unit with the supplied screws (accessories). Not doing so may cause vibration or abnormal noise.
(3) There must be no obstacles in the air discharge direction of the snow protection hood. If there are, it
may cause a short circuit or an insufficient airflow rate.
(4) Do not install other outdoor units in the direction of the air outlet. If the air blown out of the snow
protection hood is sucked into the other outdoor unit, it may cause a malfunction of the unit.
(5) The wind loads which the outdoor unit receives changes by attaching the snow protection hood. The
required installation strength will also change in strong wind. Therefore, recheck the strength of the
anchor bolts of the outdoor unit.
(6) If the snow protection hood is installed, cooling/heating performance may be slightly lowered
depending on the usage conditions.

To hold the snow protection hood properly to the outdoor unit against a strong wind or an earthquake, safety
wire rope should be used for reinforced installation. Use the field-supplied safety wire rope to prevent the
outdoor unit from overturning.
●Install the snow protection hood so as to avoid facing directly toward seasonal or strong winds.
●Apply touch-up coating or caulking (field-supplied) at the screw holes of the outdoor unit in order to
prevent rusting.
●Even though the hood is stainless, salt or iron may cause rust. Be aware of this during installation or
maintenance.
●The snow protection hood is heavy-weight. More than two people are required for installation. Be sure
to wear protective equipment (such as gloves).
●The screws and the snow protection hood must be protected from scratches or scrapes. If they aren’t,
it may be the cause of rusting. Handle with care when the snow protection hood is installed and
assembled.
3. Selection of Installation Location
(1) Install the outdoor unit at a suitable height with consideration for snow accumulation. Increase the
base height or additionally provide the frame under the unit (higher than snow accumulation), and fix
the outdoor unit securely with anchor bolts.
(2) Secure enough service space with consideration for snow accumulation height and snow removal
operation.
(3) There must be no obstacles in the air discharge direction.
(4) Be sure to apply touch-up coating or caulking agent at the screw attaching portions for rustproofing.
(5) In an instance of multiple outdoor units being installed, provide service space as shown below.

(1) Tighten the faceplate (back side) ( 4) with the right side plate ( 1) and left side plate ( 2) together
(8 places) by using screws for assembling ( 6).
(2) Tighten the faceplate (top side) ( 3) (7 places) by using screws for assembling ( 6).
(3) Tighten loosely two screws (for installation) at the top of the snow protection hood ( 5) to the outdoor
unit, and set the snow protection hood (for left side air inlet) to the outdoor unit. Tighten the other four
screws ( 5) except for the top two screws, and finally tighten the top two screws securely.
NOTE:
The fitting slots for the hood are adjustable in its fixing position within +1/8 inch (+3mm). For hood
installation, there must be no gap between the outdoor unit top plate and the hood upper part. If there

7. Maintenance and Servicing
Even if during the warranty period, the snow protection hood becomes rusted under conditions that
are caused by alkaline or corrosive moisture, recommendations are to provide salt damage resistance
products to prevent such damage.
In order to prolong product life, perform periodical maintenance to prevent significant aging due to
deterioration. Carry out the following periodical inspection and maintenance works in conjunction with air
conditioners’ inspection.
(1) Red Rust Generation and Coating Film Check
If red rust is generated, or coating film is peeled/cracked, scour the rust off or apply touch-up coating.
When recoating such parts, be sure to grind the coating using sandpaper (#180 to 230) before re-
applying coating agent. Wear protective equipment such as vinyl gloves when handling the coating
agent to prevent contact with skin.
(2) Retightening Screws for Installation and Assembly
Check for loose screws and retighten when inspection and maintenance is performed. In order to
prevent screw breakage, be sure to tighten with the following torques:
* M5 Tapping Screw Type C for Assembling 6: 2.6 + 0.7 [Ibf-ft] (3.5 + 1.0 [N•m])
* M5 Tapping Screw Type B for Installation 5: 1.8 + 0.7 [Ibf-ft] (2.5 + 1.0 [N•m])
