High Inlet Temperature Refrigerated Air Dryer
11
Installation
1. Locate unit on a level foundation. Dryer should
be mounted on a suitably structured flat and
level floor or base that is free from vibration.
2. Install unit to provide adequate clearance for
maintenance services. Dryer and accompanying
filters (optional) should be installed with at least
2 to 5 feet clearance from the adjoining walls to
provide easy access for routine maintenance and
adequate air flow across the condensing coil.
3. The frame or cabinet must be securely bolted
to the foundation to prevent movement
resulting from earth tremors and induced piping
vibration.
4. Install unit using the correct pipe size and
pressure rating. See Rating and Specification
information section. Connect the inlet of the
dryer to the moist gas from the compressor/
receiver/inlet filter. Install the Inlet piping and
the inlet shutoff valve. Install the outlet piping
and the outlet shutoff valve (a union with a
valve by-pass can be installed at the inlet and
outlet valves to accommodate isolation of the
dryer for maintenance). Compressed air piping
has to be at least the same size as that of the
inlet and outlet connections of the dryer. Larger
pipe sizes can be used with appropriately rated
reducers.
Operation at elevated pressure or temperature
may cause damage to the dryer or serious injury
to personnel. Each dryer is checked at the
factory for proper operation at the conditions
noted on the serial plate label.
5. Provide adequate power supply. See Rating
and Specification information section. Make all
electrical connections to the dryer as shown on
the wiring diagram. Special care must be taken
in connecting the proper voltage as indicated
on the specification sheet and wiring schematic.
It is mandatory that the dryer be grounded.
Use of your plant’s frame as a ground may
cause problems with the controls. A fused
disconnect is not supplied with this equipment;
therefore, one must be supplied by customer.
All electrical fuses, breakers, etc. should be
sized by a qualified electrician and comply with
all applicable national and local codes. Our
company is not liable for any code violations,
component damage, downtime or consequential
damage related to customer supplied electrical
components and connections.
6. The ambient temperature should be between 40
°F and 100 °F. Low temperature could affect
the dryer process and result in high outlet dew
point. In conditions where the ambient drops
below freezing, it is recommended that a heat
trace be used for the equipment. This will
ensure trouble-free operation during the winter
months (the dew point of the outlet air will be
consistent).
7. Do not place the system in service until the
above steps have been completed and that all
ratings and specifications have been verified to
match the requirements in this manual.
8. If there are any changes in the operating
conditions of the system from those listed
in Rating and Specification section, contact
Technical Support for advice on necessary
adjustments.
