separately or as one unit. The images in this manual show
F730 installed as one unit. For more information see

Assembly
■Position F730 on a fixed foundation that can take the
weight of the heat pump. Use the product's adjustable
feet to obtain a horizontal and stable set-up.
Because water comes from F730, the floor coating is
important. A waterproof floor or floor membrane is
recommended.
30 - 50 mm
30 - 50 mm
15 - 40 mm
20-55 mm
■Because water comes from F730, it is good if the area
where the heating pump is located is provided with
floor drainage.
■Install with its back to an outside wall, ideally in a room
where noise does not matter, in order to eliminate
noise problems. If this is not possible, avoid placing it
against a wall behind a bedroom or other room where
noise may be a problem.
■Wherever the unit is located, walls to sound sensitive
rooms should be fitted with sound insulation.
■Route pipes so they are not fixed to an internal wall
that backs on to a bedroom or living room.
■The heat pump's installation area should always have
a temperature of at least 10 °C and max 30 °C.
Installation area
Leave a free space of 800 mm in front of the product.
Leave free space between F730 and wall/other ma-
chinery/fittings/cables/pipes etc. It is recommended that
a space of at least 10 mm is left to reduce the risk of
noise and of any vibrations being propagated.
800
NOTE
Ensure that there is sufficient space (300 mm)
above the heat pump for installing ventilation
hoses.
