Assembly Of Units; Mounting The Unit; Checks Before Startup - Daikin FWP04 Installations Und Bedienungs

For each thermal ventilating unit provide a main circuit
breaker (IL), with opening contacts separated by at least 3
mm and an adequate protection fuse (F).
Electrical intakes are shown on the rating labels on the units.
During installation, strictly abide by the indications on the wir-
ing diagram for the unit-control panel combination.

ASSEMBLY OF UNITS

Mounting the unit

Insert the vibration dampers provided in the 4 slots indicated for
ceiling installation
Fasten the base unit to the ceiling or wall using the 4 slots
provided.
Ū It is recommended to use 8MA threaded bars plus screw an-
chors of adequate capacity to bear the weight of the unit,
and to prepare the positioning of the unit using 3 8MA bolts
(2 in the lower part, 1 in the upper part as shown in figure p.
63) and two washers for each bar. Before tightening the lock
nut, adjust the main nut so as to assure that the unit is prop-
erly inclined so as to facilitate condensate drainage (figure p.
6

CHECKS BEFORE STARTUP

Ū Check that the unit is installed in such a way as to guarantee
the required inclination.
Ū Check that the drainage outlet is not clogged (by masonry
debris etc.).
Ū Check the tightness of the plumbing connections.
Ū Make sure the electric wires are tightly connected (carry out
this check with the power supply OFF).
Ū Make sure that air has been eliminated from the heat ex-
changer.
Ū Power the fan coil and check its performance
FWP + FWECS p.66
NOTE: The electric wires (power and control circuits) must be
pulled in through the gland on the side of the electric box
where the plumbing connections are located and then con-
nected to the terminals.
WARNING: COMMON motor wire = WHITE, wrong connec-
tion may cause serious damages to the motor.
63 Condensate discharge ). To obtain the proper inclination,
tilt the unit so that the intake side is slightly lower (approx-
imately 10 mm) than the outlet side. Make the plumbing
connections to the heat exchanger and, where the cooling
function is to be used, to the condensate drainage outlet.
Use one of the two tray drain outlets, which can be seen on
the outside of the unit side panels
Ū To connect the unit to the drainage line, use a flexible rub-
ber hose and secure it to the pre-selected drain pipe (ø 3/8'')
using a metal clamp (use the drain outlet situated on the
plumbing connection side).
