1 . 2 Sa f e t y Gu i d e l i n e s
• Use the appropriate PPE (Personal Protective Equipment) for any handling operation.
• Before installing the air handling unit, make sure that the support and location are su󰀩ciently resist-
ant to bear the weight of the unit and accessories.
• Respect the danger labels present on the various access doors or panels:
• Live electrical equipment/Rotating machinery/Potentially ammable dust-laden lters:
FIRE DANGER
DIRTY FILTERS ARE
INFLAMMABLE
• Do not open the access doors without having cut the electrical power from the lockable safety
switch-disconnecter located on the unit
• If there is work to be performed on the device, cut the electrical power at the main circuit breaker and
make sure that nobody is able to reconnect it accidentally.
• Make sure that any mobile parts have stopped.
• Check that the fan motor is not accessible from the connection sheath.
Before start-up, check the following points:
• Ensure that the device does not contain any foreign body.
• Check that all the components are fastened in their original locations.
• Manually check that the fan is not rubbing and is not blocked.
• Check the connection of the earth electrode.
• Check that the access cover is securely closed.

The units are delivered screwed to pallets made to t the size of the casing.
KSDR ECOWATT® air handling units can be handled by pallet truck, forklift truck, or crane. Handling ma-
chines will be adapted to the load and lifting conditions.
In all cases, the lift will be made at the base of the device mounted on a pallet. The centre of gravity is
located at the centre of the unit.
The device must be handled with care and only in a horizontal position.

The KSCR ECOWATT® must be placed on a horizontal and smooth surface that is able to support the load.
The EXD and EXG models are intended for installation inside or outside of the buildings.
In all cases, provide any ducts, connection accessories, anti-vibration and anti-freezing protection equip-
ment needed for the water coil. In areas with a high snowfall, additional protection should be considered. It
is important to provide enough space so the panels can be opened, commissioned, and maintained (lter,
fan, coils). Do not place the unit against a wall to avoid the transmission of solid-state noise.
The casing must be attached to a completely at support by the side holes provided for this purpose. Mount-
ing should be made on anti-vibration pads or plates and the connection with exible sleeves is recommended.
Provide the following necessary clearances for maintenance operations:

Warning:
• For electrical heater versions, only positions
A, B and C are possible.
• With cooling and reversible coil versions, only
positions A and C are possible.
• With the cooling and reversible coil versions
in position A, reverse the drain tray (see be-
low)
• Use anti-vibration compression mounts for
position C.
• Use anti-vibration suspension mounts for po-
sition A.

If KSDR 08, 18, 28 or 38 is attached to the ceiling, install beforehand the four delivered security legs of
the cover. They allow it to be moved to the side to open the lter passage. It is su󰀩cient then to extract it
for replacement by a new lter.
To completely remove the cover, slide it sideways.
Cover xing legs setting
Unscrew the eight self-tapping screws xed on the sides of the casing. Re-attach them to secure the 4 legs.
These will allow the cover xing screws to be unscrewed without it falling.

The hydraulic specications of the unit are particular to your requirement
and are determined by computer selection: Loss of pressure of the wa-
ter/water ow. Refer to the selection for sizing the valve, accessories, and
pump.
The connection of the piping to the coil must not impose any mechanical,
vibration or thermal (dilation) constraints.
The coils are delivered already threaded at the ends.
During the tightening of the coil thread, hold the tubing with the aid of a
wrench to prevent the tubes being damaged by twisting.
Respect the water entry and exit directions indicated on the labels glued
to the coil panel(s). Water and air directions must be opposite to get max-
imum thermal performance.
All the water coil headers are 1” diameter with a male pipe thread at the end. An adaptater is provided for
the valves mounting :
• F26x34-M15x21 for KSCR 08,
• F26x34-M20x27 for KSCR 18, 28, 38 and 52.

A change-over thermostat (THCO) is to be installed on the hydraulic network and connected to the elec-
trical cabinet of the unit. It allows mixing valve control to be inverted in installations with only one coil,
according to the uid temperature detected at valve inlet.

• Spring fastening on the piping
• Electrical connection of 3 Wires 1,5 m
• IP 65 protection
Ensure the good condition and the connection of the antifreeze sensor installed on the hot water return
pipe of the unit (heating coil or reversible).
The coil headers have a male pipe thread at the end.
The motorised valves are not delivered already assembled.
Respect the positioning of the mixing valve on the network and the direction of the inlet and outlet of the
water as indicated on the label stuck to the coil panel(s).

• The unit is equipped with a droplet separator
and a condensate drain tray of stainless steel
welded at the corners.
• The condensate drain is 79 mm long and 14
mm diameter. The unit casings are all in over-
pressure during the operation of the KSCR so
that a water siphon is not required.
• Install a ball siphon to avoid the return of
odours from the network when the machine is
stopped.
• Insulate the condensate drain pipe to prevent
the formation of condensation, and to prevent
the risk of freezing of the drainage following
the conditions of use.

The ducts should not impose any mechanical constraints on the unit.
Check that the fan-motor is not accessible from the connection line (protection by the connection duct or
a steel mesh air inlet).
Depending on the conguration of the installation and the sound level required, the addition of a silencer
may be necessary at the air supply.
Take great care of the network airproof all along its length, from the entrances to the exits.
The fresh air duct must always be insulated, to avoid losses and the risk of condensation. The insulation
level, particularly in the cold rooms and regions, must be reinforced.

Smooth anges for rectangular or circular connec-
tions, to attach with crimping nuts to the suction or

When the unit is equipped with a water coil, it is advisable to provide a motorised damper with antifreeze
protection located on the fresh air network. Whenever possible, use a motorised damper with reinforced
sealing.

For constant pressure operation, it is necessary to install a pressure sensor in the supply duct at a mini-
mum distance of twice the connection diameter.
