2.2. Storage
SCC0001
Even when packaged, keep the machine protected
from severity of the weather.
Keep the dryer in vertical position, also when stored.
Turning it upside down some parts could be
irreparably damaged.
If not in use, the dryer can be stored in its packaging
in a dust free and protected site at a maximum
temperature of 120°F (50°C), and a specific humidit y
not exceeding 90%. Should the stocking time exceed
12 months, please contact the manufacturer.
The packaging materials are recyclable. Dispose of material in compliance with the rules and
regulations in force in the destination country.
2.3. Installation site
CAUTION!
Ambient conditions!
Failure to install dryer in the proper ambient conditions will affect the dryer’s ability to condense refrigerant
gas. This can cause higher loads on the compressor, loss of dryer efficiency and performance, overheated
condenser fan motors, electrical component failure and dryer failure due to the following: compressor loss,
fan motor failure and electrical component failure. Failures of this type will affect warranty considerations.
Do not install dryer in an environment of corrosive chemicals, explosive gasses, poisonous gasses; steam
heat, areas of high ambient conditions or extreme dust and dirt.
In case of fire, use an approved fire extinguisher,
water is not an acceptable means in cases of
fire.
Minimum installation requirements:
Select a clean dry area, free from dust, and protected from
atmospheric disturbances.
• The supporting area must be smooth, horizontal and able to
hold the weight of the dryer.
• Minimum ambient temperature +34 °F (+1 °C).
• Maximum ambient temperature +120 °F (+50 °C).
• Allow at least a clearance of 40 in (1m) on each side of the
dryer (80 in - 2m DRYPOINT RA 1500-2500 NA dryers) for
proper ventilation and to facilitate eventual maintenance
operations.
The dryer does not require attachment to the floor surface;
however installations where the unit is suspended require
an attachment to the hanging apparatus.

CAUTION!
Polluted inlet air!
In case of heavily polluted inlet air (ISO 8573.1 class 3.-.3 or worse quality), we recommend the additional
installation of a pre-filter (f.e. CLEARPOINT F040) to prevent a clogging of the heat exchanger
Type A installation is suggested when the compressor operates at reduced intermittence and the total consumption
equals the compressor flow rate.
Type B installation is suggested when the air consumption can consistently change with peak values highly exceeding
the flow rate of the compressor. The capacity of the tank must be sized in order to compensate eventual instantaneous
demand conditions (peak air consumption).

Example: Example:
An DRYPOINT RA 500 NA has a nominal duty of 500
scfm (849 m3/h). What is the maximum allowable flow
through the dryer under the following operating
conditions:
–Inlet air pressure = 120 psig (8 barg)
–Ambient temperature = 105°F (40°C)
–Inlet air temperature = 105°F (40°C)
–Pressure DewPoint = 38°F (3°C)
Each item of data has a corresponding numerical factor
as follows:
The procedure here is to list the operating conditions and
then to locate the corresponding numerical factors:
–Design air flow = 300 scfm (509 m
3
/h)
–Inlet air pressure = 120 psig (8 barg)
–Ambient temperature = 105°F (40°C)
–Inlet air temperature = 105°F (40°C)
–Pressure DewPoint = 38°F (3°C)
In order to select the correct dryer model the required flow
rate is to be divided by the correction factors relating to
above mentioned parameters:
= 348 scfm (591 m
3
/h) → This is the
maximum flow rate that the dryer can accept under
these operating conditions.
= 432 scfm (734 m

/h) → Therefore the model
suitable for the conditions above is DRYPOINT RA 500
NA (500 scfm or 849 m3/h - nominal duty).
