GENERAL - HD
Comfair HD fan coil units are similar in design and use to the widely
used DX high-wall mini-split systems. With a maximum width of only
210mm, the casing is manufactured from high quality plastic and
is of an aesthetically pleasing design to compliment almost every
environment.
«A BREATH OF FRESH AIR»
The fan is of a Tangential type running at low speed to guarantee
low noise levels. The concept of air discharge from the unit allows
efficient distribution of the treated air for maximum comfort, and
simplicity of use. HD units are equipped with a system of automatic horizontal air deflection through an arc of 35° in cooling operation
(10° in heating operation), which avoids stratification of the airstreams. When the unit stops, the deflector blades close automatically,
which serves not only to protect the internal components against dust but also preserves the
neat aesthetic appearance of the unit.
FILTRATION AND AIR QUALITY
The Comfair HD units not only control the temperature of the air but also the air quality in the
conditioned space. Each unit is fitted with a filter and an Ioniser which produces negatively
charged ions which attracts the positively charged dust particles and neutralises harmful
microbes present in the atmosphere. The Ioniser comprises of a small generator, which transmits
an intermittent high voltage to carbon fibres situated in the airstream.
COILS
Each unit contains a chilled and hot water coil manufactured from copper tubes with aluminium fins. Water connections are female gas
½» and each coil is fitted with an air vent. A water temperature sensor prevents low temperature discharge.
REMOTE CONTROLLER
The infa-red remote controller offers the same functions as a DX split system. It includes an LCD display which indicates the status
and set points of the unit. Sixteen buttons allow fast and easy control of the operation of all functions of the unit.

INSTALLATION - HD
INSTALLATION WITH SIMPLE MOUNTING PLATE
The method of installing the wall-mounted water-filled fan coil of the HD range is shown below. Take into account the following:
- Looking at the unit from the front, the supply pipes go from right to left.
- The system pipes must come from the left.
Make sufficient large hoel in the wall for the system water pipes
to pass through.

To HD
CAUTION! Check that the highlighted measurement is exact
1. Identify the position on the wall where the fan coil is to be installed
and create a niche with the dimensions shown bellow:
2. Cover the bottom edge of the niche with a steel angle bar
(NOT supplied). Apply the mounting plate and fix it using four
screws and four screw anchors in the relative holes:
ANGLE BAR
3. Fix the condensate collecting tray by inserting two self-tapping
screws into the relative holes. The external surface of the tray must
be flush with the wall:
4. Position the fan coil on the mounting plate:
5. Tilt the fan coil and insert the relative polystyrene foam spacer
so that the valves can be easily reached and connected to the
appliance and to the mains water supply:
6. Connect the hoses to the fan coil supply pipes and the condensate
drain hose:

CAUTION! The condensate collecting tray must be fixed so that it slopes
gently downward towards the condensate drain outlet:
N.B.:
- Do not bend or damage the enclosed mounting plate
- Comply with the highlighted measurements (previous page)
- The base of the enclosed mounting plate must project by 9-10 mm
from the wall
- The condensate collecting tray must always be flush with the wall.
