1. GENERAL INFORMATION
1.1 Functional description
Ingersoll Rand compressed air heaters are used to warm compressed air.
Compressed air enters the vessel where it is warmed to the required temperature by ohmic elements. If any liquid or dust enters the
vessel, it can be collected at the bottom and eliminated through the manual drain valve. This product can be easily installed into various
pneumatic systems in which warm air is required or desired. Please refer to Principles of Operation for complete operating details.
The product comes provided with all the control, safety and adjustment devices, therefore no auxiliary devices are needed.
A system overload not exceeding the maximum operative limits can worsen the operational performance of the product
(lower outlet temperature), but it will not affect its safety.
The electric diagram (attachment A) shows the minimum protection degree IP 54.
Improper grounding can result in electrical shock and can cause severe injury or death.
This product must be connected to a grounded, metallic, permanent wiring system or an equipment-grounding terminal or
lead on the product.
All grounding must be performed by a qualified electrician and comply with national and local electrical codes.
In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the
electric current.
Ground must be established with a bare grounding wire sized according to the voltage and minimum branch circuit
requirements.
Ensure good bare metal contact at all grounding connection points, and ensure all connections are clean and tight.
Check grounding connections after initial installation and periodically thereafter to ensure good contact and continuity has
been maintained.
Check with a qualified electrician or service technician if the grounding instructions are not completely understood, or if in
doubt as to whether the product is properly grounded.
This product is designed to work only with compressed air. For a different use, please contact your
distributor Ingersoll Rand.
1.2 Use of the device in safe conditions
This system has been designed and manufactured in compliance with the European safety directive in force, therefore any installation,
use and maintenance operations must be performed respecting the instructions contained in this manual. Because an air product is a
pressurized vessel, the same precautions should be observed as with anypiece of equipment of this type where carelessness in operation
or maintenance could be hazardous to personnel. In addition to obvious safety rules that should be followed with this type of equipment,
safety precautions as listed below must be observed.
1. Only qualified personnel shall be permitted to adjust, perform maintenance or repair this air heater.
2. Read all instructions completely before operating unit.
3. Pull main electrical disconnect switch and disconnect any separate control lines, if used, before
attempting to work or perform maintenance on the unit.
4. Do not attempt to service any part while the device is in an operational mode.
5. Do not attempt to remove any parts without first relieving the entire air system of pressure.
6. Do not operate the product at pressures in excess of its rating.
7. Inspect unit daily to observe and correct any unsafe operating conditions.
2.0 INSTALLATION
2.1 Acceptance and handling
Upon receiving your Ingersoll Rand air product, please inspect the unit closely. If rough handling is detected, please note it on your
delivery receipt, especially if the product will not be uncrated immediately. Then obtain the freight carrier's signed agreement to any noted
damages: this is a precondition for any insurance claims by the customer.
For handling, use devices having sufficient capacity for the weight of the machine.
Remove the packaging after having positioned the product in the installation site. For unpacking, refer to section 3.3.
Under no circumstances should any person attempt to lift heavy objects without proper lifting equipment (i.e., crane, hoist, slings or fork
truck). Lifting any unit without proper lifting equipment, may cause serious injury. Use fork lift channels where provided.
2.2 Storage and installation location
If not in use, the product can be stored in its packaging in a dust free and protected site between 32°F (0°C) and 120 °F (50 °C), and a
specific humidity not exceeding 90 %. Should the stocking time exceed 12 months, please contact your local Ingersoll Rand authorized
distributor.
