All units must be installed in accordance with good engineering standards, upright and
level on a prepared base. Fixing down of air handling units is at the discretion of the
installer and dependant of the site conditions.
Flexible connections are NOT recommended for connecting ductwork to the unit, as the
fan outlet is fitted with a flexible connector and is isolated from the unit via anti-vibration
If ducting is not connected it is essential that all inlets and

Provision must be made for a cleanable drain trap which should terminate at an open
drain or tundish which will ensure any blockage can be seen and remedied.
The exterior shall be kept free from falling building materials,

fitted with shields should not be stored for periods exceeding two

than that specified may be found to have a higher initial starting
torque and the service life of the grease will then be

and make sure that all the component parts of the motor are in
good condition. Cover all the ventilating holes on the motor frame
to prevent dust from entering the motor. Apply a coating of anti-
corrosion grease or other anti-corrosion agent on all the parts that
may be subject to rusting. Care must be taken to see that the
storeroom is always dry and well ventilated while the room
temperature is regularly maintained above 0°C. During storage,
periodic inspections should be made to check for moisture, rust or
hardening of grease.
The above are intended to preserve the life of all static and
moving parts of the equipment during the period of storage. It
is advisable that regular attention of the equipment is
maintained.
