Installation Manual
3P678074-1A
Read this manual and the BS/SV unit manuals carefully before use.
Safety precautions
Read these ''Safety precautions'' carefully before performing installation work.
The precautions shown here are divided into a '' Warning'' and '' Caution'' section, but those that
are likely to lead to serious consequences such as death or serious injury if the installation is performed
incorrectly are noted collectively in the '' Warning'' section. However, even the items described in the
'' Caution'' section may lead to serious consequences depending on the situation. Observe all of the
following, as each contains important information regarding safety.
After the installation work is complete, perform a test run and check that there are no abnormalities.
In addition, ask the customer to keep this manual for future reference.
Warning
• For drainage of BS/SV units. Do not use for any other application. If the usage application is incorrect,
fire/water leakage, etc. may result.
• Regarding the installation, ask your dealer or a specialist. If you perform installation work yourself and
there are imperfections in the installation, water leakage/electrocution/fire may result.
• Make sure to perform installation work properly according to the installation manual (16). If there are
imperfections in the installation, water leakage/electrocution/fire may result.
• For the safety circuit power supply wire (3), shape the wire so that the service cover of the BS/SV unit
does not rise. Install the service cover securely. If the service cover is not installed completely, electrocu-
tion/fire may result.
• Perform earthing work. Do not connect earth wires to gas pipes, water pipes, lightning rods, or
telephone earth wires. If earthing is performed incorrectly, electrocution may result.
• For installation parts, be sure to use accessories and parts with the designated specifications. If parts
without the designated specifications are used, water leakage/electrocution/fire may result.
• Turn off the power supply before performing installation work. If electrical parts are touched while the
power supply is turned on, electrocution may result.
• Connect the wire securely using the specified power supply wire (3). Secure it properly so that the
external force from the wire is not applied to the terminal connection part. If connections are incomplete
or incorrectly secured, heat generation/fire at the terminals may result.
• Install the product securely in a place that can sufficiently withstand the weight of the kit. If the strength
is insufficient, the kit may fall and cause injuries.
Caution
• For drainage work, install the pipes according to this installation manual (16) to ensure proper drainage
and insulate them to prevent condensation. If there are imperfections in the pipe work, water may leak
and cause household goods to get wet.
• Do not install in locations such as the following:
- Locations where flammable gas may leak, locations where carbon fibre and flammable dust float, or
locations where volatile flammable materials such as thinner and gasoline are handled. If gas leaks
and collects around the drain up kit (1), fire may result.
- Locations with machines that generate electromagnetic waves. These may cause abnormalities in the
control system, making normal operation impossible.

1. Preparation before installation
Preparation of the drain up kit (1)
Separate the casing and drain up kit (1) from the mounting plate.
1. Remove the casing fixing screw and washer (12). Lower the casing and pull it forward to
separate it from the drain up kit (1).
2. Remove the 2 drain up kit fixing screws. Lift the drain up kit (1) to separate it from the mounting plate.
Both soft sockets (10) as well as the soft drain pipe (11) can be cut if a shorter length is preferred. Howev-
er, make sure that the pipe never risks kinking, as a kink obstructs the flow of the drained water.
2. Preparation of the BS/SV unit
Caution
• Work with the power supply turned off.
• When connecting terminals to the inter-unit wiring terminal block, attach them correctly. If the crimp
terminals are both installed in the same orientation accidentally, the terminal contact area decreases
and there will be a risk of overheating and burning.
Precautions for power supply wire (3) (includes the earth wire)
Use round type crimp terminals to connect the inter-unit wiring terminal block and the earth wire. If for
some reason you cannot use round type terminals, observe the following items.
• Do not connect 2 wires with different diameters to the inter-unit wiring terminal block. There is risk of
abnormal heat generation due to loose wires, etc.
• Connect the wire securely using the specified power supply wire (3). Secure it in such a way that no
external force is applied to the terminal part.
• Use an appropriate screwdriver to tighten the terminal screws. A screwdriver with a head that is too
small will damage the screw heads and make proper tightening impossible.
• Respect the tightening torque of the terminal screws in the table below. Tightening the screws too much
can damage them.

3. Installation of mounting plate and tentative placement of the drain up kit (1)
1. Install the BS/SV unit.
2. Attach the drain socket accessory (accessory set of the BS/SV unit) onto the drain socket of the
BS/SV unit according to the BS/SV unit installation manual.
3. If you install the drain up kit (1) next to the BS/SV unit: attach the soft socket (10) to the accessory
and clamp it using the hose clamp (9).
4. If you install the drain up kit (1) at a distance from the BS/SV unit: adjust the distance using a hard
PVC pipe (VP13) and the soft sockets (10) on both sides of the PVC pipe.
5. Clamp the soft socket (10) onto the drain socket of the drain up kit (1) using one of the smaller hose
clamps (8).
If you install the drain up kit (1) kit at a distance from the BS/SV unit: use hose clamps (8) to tighten
both soft sockets (10) onto the PVC pipe.
6.
Important:
Position the drain socket of the drain up kit (1) at the very least 10 mm lower than the
drain socket of the BS/SV unit to guarantee proper operation of the drain up kit (1).
It is recommended to take a bit of margin and place the drain up kit (1) 20 mm lower.
7. If the drain up kit (1) will be mounted to the wall, install the mounting plate of the drain up kit (1).
Attach the mounting plate at 4 or more locations using screws (15).
If you install the drain up kit (1) onto the ceiling, fix the 2 hanger metals (14) to the mounting plate using
2 screws (13) for each hanger metal (14).
When installing the drain up kit (1) to the ceiling, use locally procured threaded rods (2x), flat washers (8x)
and M10 hexagonal nuts (8x). Install them in the ceiling at 150 mm distance.
8. Tentatively place the drain up kit (1) by hooking it on the tabs (3 locations) of the mounting plate.
9. Remove the circuit board cover.
10. If the drain up kit (1) tilts forwards, when mounting to the ceiling, adjust the M10 hexagonal nuts.

Parts required for installation (field supply)
Note 1: Secure the space required on the right of the BS/SV unit and the space required for service
around the drain up kit (1) installation location.
Note 2: Field supply pipes such as PVC pipes cannot be connected directly to the drain inlet and drain
outlet of the drain up kit (1). Use the accessories described in the installation manual (16).
Drain position
The drain up kit (1) can only be installed on the right side of the BS/SV unit. Before installing the drain up
kit (1), make sure that you have enough room above it to install the drain pipes at the outlet.There are
two ways of installing the drain up kit (1): close-by or at a slight distance. Installing the drain up
kit (1) close-by is only advised when the ducting is installed on the other side or when no ducting is
installed at all.
-
When the ducting is installed on the same side as the drain up kit (1), there is not enough room to properly
conduct maintenance on the drain up kit (1). In this case, it is advised to use PVC pipes to install the drain
up kit (1) further away.

When connecting the relay harness (2), remove the X15A short circuit connector at the leftmost main
PCB (A1P) of the BS/SV unit.
Note 1: The relay harness (2) cannot be extended, as it may malfunction due to noise.
Note 2: When the power supply is turned on, the K2R contact on the drain up kit (1) closes and becomes
a non-voltage constant B contact.
4. Installation of the relay harness (2) & power supply wire (3)
Caution
Work with the power supply turned off.
