Installation and servicing air-conditioning
equipment can be hazardous due to system
pressure and electrical components. Only trained
and qualified service personnel should install,
repair, or service air conditioning equipment.
Untrained personnel can perform basic
maintenance functions of cleaning coils and filters
and replacing filters.
All other operations should be performed by trained
service personnel When working on airconditioning equipment, observe precautions in the
literature, tags and labels attached to the unit, and
other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and
work gloves. Use quenching cloth for un-brazing
operations. Have fire extinguishers available for all
brazing operations.

This document contains general installation
instructions for the 42TW unit Fan Coils. Refer
to the unit-wiring diagram installed on the
blower housing or specific manufacturer
literature for any other type of factory-mounted
controls.
See drawings for unit configurations,
dimensions, clearances, and pipe
connections. Refer to unit wiring label for all
electrical connections; follow NEC (National
Electrical Code) and local codes.
RECEIVING
42TW fan coil units are shipped individually
packed in carton boxes. When cartons are
individually off loaded from the truck, do not
roll, nor throw, or drop the carton to avoid
damage to the contents. Store boxes upright
as the symbols on the boxes indicated. Do
not stack units more than 6 units high for size
11-16 and 8 units high for other sizes.
INSPECTION
Check the shipment against shipping list and
remove unit from the carton and take off
protective covering. If the unit has been

damaged, file claim with transportation
company and notify Carrier immediately.
PROTECTION
Protection unit from damage caused by job
site debris. Do not allow dust, debris and
water to get into the unit. These will damage
unit’s component and unit’s performance will
be affected.
PRELIMINARY
Following is a checklist which should be
checked before the installation is started. The
installer should be familiar with each of the
following requirements before the actual
installation.
- Space requirement and clearance, See
Fig.3.
- Ceiling or mounting strength.
- Piping connections.
- Condensate drain connection.
- Power supply and wiring.
- Air duct connections.
