UNPACKING

Carefully remove the DD700 dehumidifier unit from its transit box and visually
check for signs of transit damage. If there is evidence of damage DO NOT
attempt to operate the unit, call your supplier for advice. Do not discard the
packing, it will be useful when transporting the dehumidifier unit in the future.

INTRODUCTION

Dehumidifiers remove moisture from the air that is circulating through the unit.
The resulting reduction of relative humidity helps prevent rust, rot, mould,
mildew and condensation within the room, or other enclosed spaces where
the dehumidifier is used.
The DD700 is of the desiccant wheel type designed to dry air by passing a
large volume of air, the “process” air through a slowly rotating Silica gel rotor.
Silica gel is a hygroscopic material that absorbs moisture direct from the air.
As the air passes through the rotor the humidity of the air is reduced, whilst
the moisture content of the rotor is increased. A smaller volume of air, the
reactivation air, is heated by an internal heater and passes through a portion
of the rotor in the opposite direction. As this heated air passes through the
rotor it will “reactivate” it by removing the moisture content from the silica gel
material. The reactivation air will leave the humidifier as warm, moist air and
must be vented to outside of the building.

Continuous circulation of the room air through the dehumidifier unit gradually
reduces the relative humidity in the room.

The DD700 dehumidifier is a robust, compact unit designed to control the
humidity in the enclosed space in which it is placed. The casing is fabricated
from Steel then painted and has been designed for the exacting conditions
which can prevail in offices, shops, houses, restaurants, public houses etc. It
combines lightness and compactness with high reliability and strength.

The unit is thermally protected and will automatically switch off in excessive or
abnormal conditions.

The dehumidifier has two separate filters. One in the “process” air inlet and
one in the “reactivation” air inlet, used to clean the air entering the
dehumidifier.

UNIT CAPACITY

The ambient conditions of the area to be dehumidified will determine the
amount of water extraction the unit is cable of.
Measure the ambient conditions of the area to be determined and then use
that information with the following capacity diagram to determine the unit
capacity.

INSTALLATION

The DD700 is designed for indoor use. The unit should be placed on a level
surface and a space of 3 ft free around all faces to allow access for any duct
work and servicing.

Connecting duct work:

The regeneration outlet must be ducted to outside the area being
dehumidified. The outlet duct spigot is 6” diameter and only 6” ducting or
greater should be attached.

The process outlet can be ducted to a specific area or another room. The
outlet duct spigot is 8” diameter and only 8” ducting or greater should be
attached.

Power Supply & Humidistat Control:

The unit must be connected to a suitable 220V, 3 phase, 60Hz supply.

THIS APPLIANCE MUST BE EARTHED

Feed power cables through the gland provided and then wire the unit as
shown below.

An external humidistat can also be used to control the relative humidity in the
dehumidified area. If a humidistat is used then the wires should pass through
the gland provided and then wired as below.
