Important safety information
1. The compactness of the K..-EF series, plus the adaptability
to be mounted in any position, permits easy installation.
This straight-thru air flow fan can be mounted at any
angle from horizontal to vertical.
2. Because this unit has rotating parts, safety precautions
should be exercised during this phase of installation,
operation and maintenance.
3. CAUTION: For General Ventilation Use Only. Do Not Use
To Exhaust Hazardous Or Explosive Material and Vapors.
4. Remove unit from package and inspect within 15 days
after receipt. If damaged, report damage to carrier. Do
NOT operate this unit with visible damage to the blower
or impeller assembly.
5. For K...-EF Series fans, if bracket is used to mount fan,
refer to illustration 1. If suspending fan with hanger traps,
refer to illustration 2.
6. To attach duct work, use duct tape at inlet and outlet to
assure good seal. If using Systemair FK clamps: attach FK
clamps and insert screws through clamp into inlet and
outlet flanges.
CAUTION: Use 1/2" sheet metal screws to secure duct
work to inlet and outlet. It is critical that the screw
penetrate the metal of the inlet flange but not so far as
to bind the impeller. It may be necessary to angle screws
away from impeller.
CAUTION: If not using Systemair FK clamps use 1/4"
screws.
7. Screen guards must be installed when fan will be within
reach of personnel, within seven (7) feet of working area,
or when advisable for safety.
8. An appropriate duct termination device (roof cap, wall
cap, louvered shutters, etc.) are to be used with this fan.
