Sure-Aire™ Flow Monitoring System

®
This instruction manual provides installation, operating, maintenance, and other information for the Sure-Aire™
electronics.
Receiving
Upon receiving the electronics, check to ensure all items are accounted for by referencing the packing list. Inspect
each crate or carton for shipping damage before accepting delivery. Alert the carrier of any damage detected. The
customer will make notification of damage (or shortage of items) on the packing list and all copies of the bill of lading
which is countersigned by the delivering carrier. If damaged, immediately contact your local sales representative.
Any physical damage to the unit after acceptance is not the responsibility of the manufacturer.
Unpacking
Verify that all required parts and the correct quantity of each item have been received. If any items are missing,
report shortages to your local representative to arrange for obtaining missing parts.
Storage
Electronics are protected against damage during shipment. If the electronics cannot be installed and operated
immediately, precautions need to be taken to prevent deterioration during storage. The user assumes responsibility
of the electronics and any accessories while in storage. The manufacturer will not be responsible for damage during
storage. These suggestions are provided solely as a convenience to the user.
The ideal environment for the storage of electronics is indoors, above grade, in a low humidity atmosphere which
is sealed to prevent the entry of blowing dust, rain or snow. Temperatures should be evenly maintained between
30
°
to 110
°
F (
-1° to 43°C
). Wide temperature swings may cause condensation and “sweating” of metal parts. All
accessories must be stored indoors in a clean, dry atmosphere.
Removing from Storage
As electronics are removed from storage to be installed in their final location, they should be protected and
maintained in a similar fashion until the control goes into operation. Environmental Operation Range: -4
°
to 140
°
F
(
-20° to 60°C
).
1. Mount the electronics in the vertical plane using
four (4) #8-32 screws, field supplied. Open the front
cover by unscrewing the two captive thumb screws
to gain access to the four mounting locations.
Note:
Mount the Sure-Aire™ electronics within
75 feet of the fan.
WARNING
When wiring the electronics, you must follow industry
standard practices for controls and protect against
electrostatic discharge (ESD). Failure to exercise good
ESD practices may cause damage to the electronics.
