INSTRUCTIONS AND CARE
The fans are assembled with both Inlet and Outlet Safety Guards that conform to the safety standards to prevent danger zones being reached by upper limbs in the BS EN ISO 12100 Safety Machinery – Guards Standard.
Installation and Start-Up
- During the installation and start-up of the RAMFAN blowers in areas where there is a risk of explosion:
- The design of the electrical installations must be in accordance with EN/IEC/ABNT NBR IEC 60079-14.
- Ensure the power source is providing an electrical ground.
- Blowers must be integrated into a system in a way to supports accessibility for regular maintenance.
- Blowers are designed for portable, nonfixed installation. Blowers have no mounting features to support rigid ducts or fix installations.
- Perform careful inspection of each blower system to ensure ducting is securely attached to the blower. All components of the blower system are made of electrically conductive material. It is very important to properly and securely attach each component to maintain a ground path.
- Inspect the fan power cable and plug for damage or wear that could render the cable unsafe for hazardous locations.
- Ensure set-up, installation, operation, and maintenance are performed only by properly trained personnel.
- Operation after a faulty installation or maintenance shall be considered as
Before STARTING the FIRST time
DO NOT start operation if there are any signs of shipping damage to the
blade, guards or housing. STOP, call your dealer. USE Ex-Rated receptacles for
this equipment. IT IS NOT recommended to use extension cords for high amperage
load. (See power rating label on limit)
OPERATION
- Always ensure the switch is in the “Down/OFF” position prior to connecting the ventilator to a power source.
- Completely uncoil the fan power cable to the AC power source.
- Route fan power cable to avoid contact with heavy machinery that could possibly damage the cable or possibly be a trip hazard for workers.
- Connect the plug end of the fan power cable to the AC power source. Verify AC power source is providing an electrical ground connection.
- NOTE: For ATX connectors lift dust covers and insert the plug into the coupler until the coupler dust cap latches snaps into position on the plug. To break the connection between the coupler and plug lift dust cap to pull the connectors apart.
- NOTE: For CEAG connectors lift the dust cover, insert the plug into the coupler, and rotate clockwise, to lock the plug into the coupler and to close the power switch within the coupler. To break the connection between the coupler and plug lift the dust cap and rotate the plug counter-clockwise to pull the connectors apart.
- Note : For R.STAHL connectors insert the plug into the coupler and rotate the outer ring clockwise to secure the plug to the coupler.
- See Illustrations (Pg.6)
- Stop the blower if mechanical noise, vibration, or other abnormal conditions occur. Any noise other than turbine-type pitch is not normal.
- This unit is equipped with thermal overload protection with automatic reset. The motor will restart without warning after protector trips. To protect the user, disconnect the unit and determine the cause of the protector trip.
- Conductive RAMFAN Portable Ventilators are made with statically conductive materials. When ducting is required to remove the ventilator from the point of application in a potentially explosive environment, the ducting must be:
- Statically Conductive, Surface resistance ≤106 ohms.
- Flexible.
MAINTENANCE
- Disconnect power before inspection, disassembly, or cleaning.
- Never immerse or directly spray the motor with liquids.
- Clean ventilator with commercially available biodegradable cleaning solutions. Do not use solvents containing hydrocarbons (i.e. MEK, Acetone).
- Inspect clearance between impeller tips and fan casing for minimum acceptable clearance with pin gauges as shown in the picture below. The minimum acceptable impeller tip clearance is 0.079” / 2mm
- Clean the fan, impeller, & motor to remove accumulated dust or debris. Clean the impeller and motor with a damp cloth only, to avoid any possibility of a disruptive breakdown due to electrostatic charging.
- Inspect impeller & finger guards annually for damage. Replace as necessary.
- Inspect the fan power cable and plug for damage or wear that could render the cable unsafe for hazardous locations.
- Disconnect the fan power cable plug from the power source before cleaning. Never immerse or directly spray cables and plugs with fluids. Clean cables with commercially available biodegradable cleaning solutions. Do not use solvents containing hydrocarbons (i.e. MEK, Acetone).
- At a minimum, check power cables during maintenance work on the fans for:
- Firm fit of the conductors.
- Damage on the enclosure; seals or surface.
- Dirt on the sleeves.
- To avoid electrostatic charging, the devices located in potentially explosive areas may only be cleaned using a damp cloth.
- When cleaning with a damp cloth, use water or mild, non-abrasive, non-scratching cleaning agents.
- Do not aggressive detergents or solvents.
- Prevent water and cleaning agents from penetrating the socket contacts.
- There are no user-serviceable parts. Contact the factory for replacement part applicability.
