Working Procedure; Electrical Wiring - Fujitsu Airstage AUXD18GALH Installationsanleitung

Working procedure

(1) Install the attached drain hose to the drain port of the body. Install the hose band from
the top of the hose within the graphic display area. Secure fi rmly with the hose band.
(2) Use vinyl adhesive agent to glue the drain piping (PVC pipe VP25) which is prepared
on site or elbow socket.
(Apply color adhesive agent evenly until the gauge line and seal)
(3) Check the drainage. (See separate diagram)
(4) Install the heat insulation.
(5) Use the attached heat insulation to insulate the drain port and band parts of the body.

Note: Check for drainage
Pour about 1 liter of water from the position shown in the diagram or from the airfl ow
outlet to the dew tray. Check for any abnormalities such as strange noises and whether
the drain pump functions normally.

6. ELECTRICAL WIRING

WARNING
Electrical work must be performed in accordance with this Manual by a person
certifi ed under the national or regional regulations. Be sure to use a dedicated circuit
for the unit.
An insuffi cient power supply circuit or improperly performed electrical work can cause
serious accidents such as electric shock or fi re.
Before starting work, check that power is not being supplied to the all units.
For wiring, use the prescribed type of cables, connect them securely, making sure
that there are no external forces of the cables applied to the terminal connections.
Improperly connected or secured cables can cause serious accidents such as
overheating the terminals, electric shock, or fi re.
Securely install the electrical box cover on the unit.
An improperly installed electrical box cover can cause serious accidents such as
electric shock or fi re through exposure to dust or water.
Install sleeves into any holes made in the walls for wiring. Otherwise, a short circuit
could result.
Use the included connection cables and power cables or ones specified by the
manufacturer. Improper connections, insufficient insulation, or exceeding the
allowable current can cause electric shock or fi re.
Do not modify the power cables, use extension cables, or use any branches in the
wiring. Improper connections, insufficient insulation, or exceeding the allowable
current can cause electric shock or fi re.
Match the terminal block numbers and connection cable colors with those of the
outdoor unit (or RB unit). Erroneous wiring may cause burning of the electric parts.
Securely connect the connection cables to the terminal board. In addition, secure the
cables with wiring holders. Improper connections, either in the wiring or at the ends
of the wiring, can cause a malfunction, electric shock, or fi re.
Always fasten the outside covering of the connection cable with the cable clamp. (If
the insulator is chafed, electric discharge may occur.)
Install an earth leakage breaker. In addition, install the earth leakage breaker so
that the entire AC main power supply is cut off at the same time. Otherwise, electric
shock or fi re could result.
Always connect the earth (ground) cable.
Improper earthing (grounding) work can cause electric shocks.
Install the remote controller cables so as not to be direct touched with your hand.
Perform wiring work in accordance with standards so that the air conditioner can be
operated safely and positively.
Connect the connection cable fi rmly to the terminal board. Imperfect installation may
cause a fi re.
If the supply cable is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualifi ed persons in order to avoid a hazard.
CAUTION
Earth (Ground) the unit.
Do not connect the earth (ground) cable to a gas pipe, water pipe, lightning rod, or a
telephone earth (ground) cable.
Improper earthing (grounding) may cause electric shock.
Do not connect power supply cables to the transmission or remote controller terminals,
as this will damage the product.
Never bundle the power supply cable and transmission cable, remote control cable
together. Separate these cable by 50 mm or more. Bundling these cables together will
cause miss operation or breakdown.
When handling PCB, static electricity charged in the body may cause malfunction of the
PCB. Follow the cautions below:
• Establish an earth (ground) for the indoor and outdoor units and peripheral devices.
• Cut power (breaker) off.
• Touch metal part of the indoor units for more than 10 seconds to discharge static
electricity charged in the body.
• Do not touch terminals of parts and patterns implemented on PCB.
