SAFETY CONSIDERATIONS

The equipment covered by this manual is designed for safe and reliable operation when installed and oper­ated within its design specification limits. To avoid personal injury or damage to equipment or property
while installing or operating this equipment, it is essential that qualified, experienced personnel perform
these functions using good judgement and safe practices. See the following cautionary statements.

DANGER

ELECTRICAL SHOCK HAZARDS. All power must be disconnected prior to installation and serving this equip­ment. More than one source of power may be present. Disconnect all power sources to avoid electrocu­tion or shock injuries.

MOVING PARTS HAZARDS. Motor and Blower must be disconnected prior to opening access panels. Motors
can start automatically, disconnect all power and control circuits prior to servicing to avoid serious crush­ing or dismemberment injuries.

HOT PARTS HAZARD. Electric Resistance heating elements must be disconnected prior to servicing. Electric
Heaters may start automatically, disconnect all power and control circuits prior to servicing to avoid burns.

WARNING

Check that the unit assembly and component weights can be safely supported by rigging and lifting equip­ment.

All assemblies must be adequately secured during lifting and rigging by temporary supports and restraints
until equipment is permanently fastened and set in its final location.

All unit temporary and permanent supports must be capable of safely supporting the equipment's weight
and any additional live or dead loads that may be encountered. All supports must be designed to meet
applicable local codes and ordinances.

All fastening devices must be designed to mechanically lock the assembly in place without the capability
of loosening or breaking away due to system operation and vibration.

CAUTION

Secure all dampers when servicing damper, actuator or linkages. Dampers may activate automatically, dis­connect control circuits or pneumatic control systems to avoid injury.

Protect adjacent flammable materials when brazing, Use flame and heat protection barriers where need­ed. Have fire extinguisher available and ready for immediate use.

SECTION ONE: Receipt & Installation

PREFACE

Environmental Technologies fan coils represent a prudent investment which can, with proper installation,
operation, and regular maintenance, give trouble-free operation and long service.

Your equipment is initially protected under the manufacturer’s standard warranty; however, this
warranty is provided under the condition that the steps outlined in this manual for initial inspec­tion, proper installation, regular periodic maintenance, and everyday operation of the equipment
be followed in detail. This manual should be fully reviewed in advance of any actual work being
done on the equipment. Should any questions arise, please contact your local Sales Representative
or the factory BEFORE proceeding.

The equipment covered by this manual is available with a vast variety of options and accessories. Consult
the approved unit submittal, order acknowledgement, and other manuals for details on the options and
accessories provided with the equipment on each project.

NO ATTEMPT SHOULD BE MADE TO HANDLE, INSTALL, OR SERVICE ANY UNIT

WITHOUT FOLLOWING SAFE PRACTICES REGARDING MECHANICAL EQUIPMENT.

• Equipment must always be properly supported. Temporary supports used during installation or service
must be adequate to hold equipment securely.

• CAUTION: All power must be disconnected before any installation or service should be attempted. More
than one power source may be supplied to a unit. Power to remote mounted control devices may not
be supplied through the unit.

• Never wear bulky or loose fitting clothing when working on any mechanical equipment. Gloves should
only be worn when required for proper protection from heat or other possible injury. Safety glasses or
goggles should always be worn when drilling, cutting, or working with chemicals such as refrigerants
or lubricants.

• CAUTION: Never pressurize any equipment beyond specified test pressures. Always pressure test with
some fluid or inert gas such as clear water or dry nitrogen on refrigeration systems to avoid possible
damage or injury in the event of a leak or component failure during testing.

• CAUTION: Always protect adjacent flammable material when welding or soldering. Use suitable health
shield material to contain sparks or drops of solder. Keep a fire extinguisher nearby.

The manufacturer assumes no responsibility for personal injury or property damage resulting from improp­er or unsafe practices during the handling, installation, service, or operation of any equipment.

UNPACKING & INSPECTION

All units are carefully inspected at the factory throughout the manufacturing process under a strict detailed
quality assurance program, and where possible, all major components and subassemblies are carefully test­ed for proper operation and verified to be in full compliance with the factory manufacturing documents.
The only exception to this being the operational testing of some customer furnished components such as
control valves and switches.

Each unit is then carefully packaged for shipment to avoid damage during normal transport and handling.
The equipment should always be stored in a dry place in the proper orientation as marked on the pack­aging.

All shipments are made F.O.B. factory and it is the responsibility of the receiving party to inspect the equip­ment upon arrival. Any obvious damage to the packaging and/or its contents should be recorded on the
bill of lading and a claim should be filed with the freight carrier.

After determining the condition of the unit‘s exterior, carefully remove each unit from the
packaging and inspect for hidden damage. At this time, check to make sure that “furnished only” items
such as switches, thermostats, etc. are accounted for. Any hidden damage should be recorded and imme­diately reported to the carrier and a claim filed as before. In the event a claim for shipping damage is filed,
the unit, shipping package, and all packing must be retained for physical inspection by the freight carri­er. All equipment should be stored in the factory shipping package with internal packing in place until
installation.

ETI performs a series of rigorous leak tests on all of the piping installed in this equipment to ensure pip­ing integrity. Because this equipment may be shipped with factory supplied external riser piping, it is nec­essary for the receiving inspector to carefully inspect this piping for signs of shipping damage. If damage
is present, a claim must be filed with the freight carrier (refer to ETI Policy # PP-LOSS-DMG).

At the time of receipt, the equipment type and arrangement should be verified against the order docu­ments. Should any discrepancy be found, the local Sales Representative should be notified immediately so
that the proper action may be instituted. Should any question arise concerning warranty repairs, the fac­tory must be notified BEFORE any corrective action is taken. Where local repairs or alterations can be accom­plished, the factory must be fully informed as to the extent and expected cost of those repairs before work
is begun. Where factory operations are required, the factory must be contacted for authorization to return
equipment and a Return Authorization Number will be issued. Unauthorized return shipments of equip­ment and shipments not marked with an authorization number will be refused. In addition, the manu­facturer will not accept any claims for unauthorized expenses.

SHIP LOOSE ITEMS

Several components are shipped loose for field installation. These are: thermostat, return air access panel,
return air access panel fasteners, discharge grille(s), risers (optional). These parts are shipped loose to offer
protection against shipping and job-site damage. Refer to packing slip.
