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.
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. Motor will
restart without warning after protector trips. To protect the user, disconnect unit and
determine cause of protector trip.
Conductive RAMFAN Portable Ventilators are made with statically conductive materials.
When ducting is required is required to remote the ventilator from the point of application in
a potentially explosive environment, the ducting must be:
1. Statically Conductive, Surface resistance ≤106 ohms.
2. Flexible.
3. Reinforced with integrated helical steel wire, spaced to prevent duct material
from collapsing, when airflow is inadvertently blocked on suction side of duct.
MAINTENANCE
• Disconnect power before inspection, disassembly or cleaning.
• Never immerse or directly spray 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 picture below. Minimum acceptable
impeller tip clearance is 0.079” / 2mm.
• Clean 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.
• There are no user serviceable parts. Contact factory for replacement part
applicability.
• Do not change make or model number of motors for any reason!
