Receiving
Upon receiving the product check to make sure all
items are accounted for by referencing the bill of
lading to ensure all items were received. Inspect
each crate for shipping damage before accepting
delivery. Notify the carrier if any damage is noticed.
The carrier will make notification on the delivery
receipt acknowledging any damage to the product.
All damage should be noted on all the copies of
the bill of lading which is countersigned by the
delivering carrier. A Carrier Inspection Report should
be filled out by the carrier upon arrival and reported
to the Traffic Department. If damaged upon arrival,
file a claim with carrier. Any physical damage to
the unit after acceptance is not the responsibility of
Greenheck Fan Corporation.
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. Sometimes it is not possible that all items
for the unit be shipped together due to availability
of transportation and truck space. Confirmation of
shipment(s) must be limited to only items on the bill
of lading.
Handling
The motor amperage and voltage ratings must be
checked for compatibility to supply voltage prior
to final electrical connection. Wiring must conform
to local and national codes. Consult local code
authorities for specific requirements.
Storage
Product is protected against damage during
shipment. If the product cannot be installed and
operated immediately, precautions need to be
taken to prevent deterioration of the product during
storage. The user assumes responsibility of the
product and 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.
Indoor Only
Do not store this product outdoors. The ideal
environment for the storage of this product 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.
Remove any accumulations of dirt, water, ice, or
snow and wipe dry before moving to indoor storage.
Allow cold parts to reach room temperature to
avoid “sweating” of metal parts. To dry parts and
Parts Needed (Not provided by Greenheck)
• 18 - 20 gauge 3-wire plenum rated control wire
• 1/4 inch inside diameter plastic tubing
• Normally Open switch or relay for optional remote
override
Pressure Taps
Either room or duct pressure taps may be used. Be
sure to mount them in the room or duct system you
intend to control.
Be careful not to pinch or kink the pressure tubing
anywhere along its length.
Condensation running down the interior of the
pressure tubing may damage the controller’s sensor.
Forming a drip loop in the tubing just before it enters
the Greenheck Constant Pressure Controller is good
practice. (The distance from the bottom of the loop
to the controller’s pressure port should be one to two
inches [2.5 to 5 cm] greater than the highest static
pressure, including error conditions, in the system.)
Drip Loop
packages, use a portable electric heater to get rid
of any moisture buildup. Leave coverings loose
to permit air circulation and to allow for periodic
inspection. The unit should not be stored on the
floor.
Inspection and Maintenance
During Storage
While in storage, inspect product once per month.
Keep a record of inspection and maintenance
performed. If moisture or dirt accumulations are
found on parts, the source should be located and
eliminated.
Installation and Setup Guide
This guide provides instructions for how to
install, wire and program the control system for
use when constant pressure in a duct or room
system is required. This does not cover ductwork
recommendations or other considerations. When
installed, this control system will automatically vary
the speed of the fan to maintain a constant pressure
within the system.
