Loren Cook Cook Flow Monitor System Installation, Operation And Maintenance Manual

®
This installation manual provides information for installing and
confi guring the Cook Flow Monitor System. The system in-
cludes a Loren Cook Company fan with a piezometric ring (p-
ring) and the Cook Flow Monitor. The manual does not cover
any other installation details or applications.
Carefully read this publication and any sup-
plemental documents prior to any installation
or maintenance procedure.
For additional safety information, refer to AMCA publication
410-96, Safety Practices for Users and Installers of Industrial
and Commercial Fans. This document and all Cook publica-
tions may be obtained from Cook by phoning (417) 869-6474,

Location and Maintenance
Consider the following points while choosing a location for the
Cook Flow Monitor.
• Do not place the device on the fl oor.
• Maintain a temperature between -1°C to 43°C (30°F to
110°F). A temperature beyond this range may cause con-
densation and sweating of metal parts.
• Maintain a low humidity, dry, and clean atmosphere. En-
sure that the device is not in the path of blowing dust, rain,
or snow.
Follow these guidelines prior to installation.
• Clean the components to remove any deposit of dirt,
water, ice, or snow and wipe them dry.
• Dry components using a portable electric heater to
remove any buildup of moisture.
• Allow the cold metal parts to reach room temperature to
avoid sweating.
Voltage Warning
Low-voltage control wires and line voltage power wires must not be
installed in same conduit. Failure to follow these instructions could
result in malfunction or damage.
Disconnect Warning
ALWAYS disconnect power prior to working on fan. Failure to
comply with these safety precautions could result in property
damage, serious injury, or death.

INSTALLATION, OPERATION AND MAINTENANCE MANUAL
Installation
The following steps and components are important to the
proper operation of the Cook Flow Monitor System.
Pressure Ports
The system requires connecting the pressure ports on the
Cook Flow Monitor to the pressure ports located on the fan
labeled Piezometric Connections.(See Fig. 1) Follow these
guidelines while making the connections.
• The connections require the use of 1/4" OD tubing. The
connection at the Flow Monitor utilizes barb fi ttings on
the exterior of the enclosure while the connection at the
fan uses push-to-connect fi ttings located on the exterior
of the fan near the inlet.
• Connections are labeled HIGH and LOW on the monitor
as well on the fan. See Figures 2 and 3.
• Keep the length of tubing between the pressure ports to
50 feet (15m) or less.
• Ensure that there are no kinks along the length of the
pressure tube.
• Do not pinch the pressure tube.
• Form a drip loop in the tubing as it enters the fl ow moni-
tor. This avoids condensation build up inside the pres-
sure tube and damage to the device's sensor.
• Drip loop should be at least 1" (25mm) greater than high-
est measured pressure (as measured in inches, w.c.)
factoring in error conditions in the system. (Example: If
pressure being measured is 4" w.c., then the bottom of
drip loop should be 5" or more below the high pressure
port.)
