SAFETY CONSIDERATIONS

Air-handling equipment is designed to provide safe and reliable service when operated within design specifications. To avoid injury to personnel and damage to property or equip­ment, use good judgment and follow safe practices as outlined below when installing and operating this equipment.
DANGER
NEVER REACH INTO a unit while the fan is running. LOCK OPEN AND TAG the fan motor power disconnect
switch before working on unit. In addition, remove the fuses and take them with you after noting this on tag.
DISCONNECT ALL POWER before attempting any installation or service. More than one power source may be supplied to a unit. Power to remote mounted control devices may not be supplied through the unit.
CHECK THE WEIGHT of assembly and components to be sure that rigging equipment can handle them safely.
NEVER PRESSURIZE a coil with a non-liquid for leak testing. A dangerous burst may occur.
DO NOT STEAM CLEAN coils until you are sure all per­sonnel are clear of the area.
Failure to follow these warnings will result in severe per­sonal injury or death.

INTRODUCTION

The following contains general installation instructions for the 42BHE,BVE fan coil units. See Fig. 1 for components. Re­fer to the unit wiring diagram installed on the blower housing or specific manufacturer literature for any other type of factory­mounted controls.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

es, and pipe connections. Refer to unit wiring label for all elec­trical connections. Follow NEC (National Electrical Code) and local codes.

INSTALLATION

Step 1 — Unpack and Inspect Unit —
ping wraps from unit and check shipment against shipping list. Check for concealed shipping damage. If shipment is damaged or incomplete, file claim with transportation company and contact your local Carrier representative immediately.
Remove ship-
Step 2 — Protect Unit from Damage — To main-
tain warranty, protect unit against adverse weather conditions, theft or vandalism on the jobsite.
The described equipment IS NOT suitable for outdoor in­stallations. The equipment should never be stored or installed where it may be subjected to a hostile environment such as rain, snow, or extreme temperatures.
Step 3 — Prepare Jobsite — To save time and to re-
duce the possibility of costly errors, set up a complete sample installation in a typical room at jobsite. Check all critical di­mensions such as pipe, wire and duct connection requirements. Refer to job drawings and product dimension drawings as re­quired. Instruct all trades in the appropriate part of the installa­tion. For unit component identification, refer to Fig. 1. For unit dimensions, refer to Fig. 2-4 for 42BHE units. Refer to Fig. 5-7 for 42BVE units.
