Introduction
in.yj
small package, zero compromise
Say hello to the newest member of the Y Series!
The in.yj’s size makes it easy to install in your small
footprint spa, without losing out on functionality and
options.
It also offers total heating flexibility. The pack can be
bought on its own for use in a heat recovery system
(in.yj-re), or bundled with the compact heat.wav-yj heater
for efficient heating in any space.
Like all Y Series packs, the in.yj is compatible with our
in.k series of keypads. And what's more, the Y Series also
takes into account future compatibility, so you can have
peace of mind knowing that you can enjoy the Y Series for
years to come.

In.seal provides an extra level of protection against
water infiltration. Connectors and power box are
designed to be watertight so that no water can
be in direct contact with electrical components
(IPX5).
in.seal
watertight protection
in.flo is an all-electronic dry-fire protection that is
built in to the remote heat.wav heater. The in.flo
eliminates the burden of adjustments, calibrations
and failures associated to usual water flow sensors.

dry-fire protection
in.t.cip is an intelligent water temperature refresh
algorithm that calculates optimal time to start
pumps and get water temperature readings.
In.t.cip continuously readjusts the heater start
time (according to exterior temperature).

Features
The Y Series systems boast a long list of technical features. Each of them contributes to bringing the most advanced
solutions available to Y Series equipped spa owners:
The in.stik is a pen drive with an in.link connector
very similar to a USB memory stick. It connects
to the spa pack and contains data to program or
configure its system. The system executes the
data upload automatically.
in.stik
automated software upload
All Y Series packs support the in.touch WiFi
interface, allowing you to use your favorite iOS
device to communicate with your spa.
in.touch
you're always in touch with your relaxation
The Y Series is only compatible with the low-
voltage family of in.link connectors, such as
those used by keypads and similar low-voltage
accessories.

ingenious plugs and connectors
In.put was designed to ease wire insertion
(up to # 6 AWG) and connections. Tighter input
connection reduces heat generated for increased
component lifetime.

Warning!
Beware of the application of some products
commonly used against corrosion (such as
WD-40 family products) as they could damage
the pack, due to a negative chemical reaction
between some industrial oils and its plastic
enclosure. Any other materials which may
come in contact with the enclosure must be
carefully evaluated under end use conditions for
compatibility.
To prevent water from getting inside 2 positions are allowed.

Flat aluminum brackets are designed for back wall
mounting. There are 5 possible positions you can use.
Multiple brackets can be used if extra support is needed.
Fasten the mounting bracket(s) to the back of the pack
with the supplied screws.
Part number:
Wall mount bracket kit 100 pcs - 9920-101474
(with 200 screws to attach to pack)
Using the brackets, fasten pack to 2" x 4" or 2" x 6" timber
wall studs under the spa. We recommend using #10 self
threading screws with pan or truss heads and washers
1/2" OD x 1/16” (12 mm OD x 1.5 mm).
Note: The spa pack must be installed at least 4" (100 mm) above
potential flood level. If floor is on ground level, pack should be
raised at least 4" (100 mm).
Two types of brackets can be used to secure the pack:

heat.wav installation (not applicable on in.yj-re models)
The heat.wav heating element must be installed in the
return circuit of the main pump (pressure side).
The aluminum Z-bracket is designed for flush-mounting
the pack directly on the edge of the access door frame
of your spa. It can be mounted to the pack in one of
4 positions for greater flexibility.
Fasten the mounting bracket(s) to the back of the pack
with the supplied screws.
Part number:
Z-bracket in.yj kit 100 pcs - 9920-101478
(with 200 screws to attach to pack)
Depending on your specific needs, you can fasten with
two #10-24 screws of your choice.
Note: The spa pack must be installed at least 4" (100 mm) above
potential flood level. If floor is on ground level, pack should be
raised at least 4" (100 mm).
