INSTALLATION & MOUNTING INSTRUCTIONS

Start up and Operation

General
Before beginning start up operation, familiarize yourself with
the unit, options, accessories and controls so you understand
proper system operation. All personnel should have a good
working knowledge of general start-up procedures and have
the appropriate start-up and balancing guides available for
consultation.
NOTE: Water coils are not to be flipped in the field. This will
cause loss of performance due to improper piping and
condensate issues due to inadequate drainage.
Cooling/Heating Coils
Prior to the water system start-up and balancing, the chilled/hot
water systems should be flushed to clean out dirt and debris,
which may have collected in the piping during construction.
During this procedure, all unit service valves must be in the
closed position. This prevents foreign matter from entering
the unit and clogging the valves and metering devices. Filters
should be installed in the piping mains to prevent this material
from entering the units during normal operation. During system
filling, air venting from the unit is accomplished by the use of
the standard manual air vent fitting installed on the coil. Manual
air vent fitting: the screw should be turned counterclockwise
no more than 1-1/2 turns to operate the air vent.
CAUTION: The air vent provided on the unit is not intended to
replace the main system air vents and may not release air trapped
in other parts of the system. Inspect the entire system for potential
air traps and vent those areas as required, independently. In
addition, some systems may require repeated venting over a
period of time to properly eliminate air from the system.
Water System Balancing
A complete knowledge of the hydronic system, its
components, and controls is essential to proper water system
balancing and this procedure should not be attempted by
unqualified personnel. The system must be complete and
all components must be in operating condition BEFORE
beginning water system balancing operations. Each hydronic
system has different operating characteristics depending on
the devices and controls in the system. The actual balancing
technique may vary from one system to another.
After the proper system operation is established, the appropriate
system operating conditions such as various water temperatures
and flow rates should be recorded in a convenient place for
future reference. Before and during water system balancing,
conditions may exist which can result in noticeable water noise
or undesired valve operation due to incorrect system pressures.
After the entire system is balanced, these conditions will not
exist on properly designed systems.
Air System Balancing
All ductwork must be complete and connected, and all grilles,
filters, access doors and panels must be properly installed
to establish actual system operating conditions BEFORE
beginning air balancing operations. Each individual unit and
attached ductwork is a unique system with its own operating
characteristics. For this reason, air balancing is normally done
by balance specialists who are familiar with all procedures
required to properly establish air distribution and fan system
operating conditions.
These procedures should not be attempted by unqualified personnel.
After the proper system operation is established, the actual
unit air delivery and the actual fan motor amperage draw for
each unit should be recorded in a convenient place for future
reference such as the inspection, installation, & start-up check
sheet, a copy of which is provided on the back of this manual.
Contact the sales representative or the factory for additional
copies of this sheet.
The manufacturer assumes no responsibility for undesirable
system operation due to improper design, equipment or
component selection, and/or installation of ductwork, grilles,
and other field supplied components.
