REMOTE CONTROL

Fig. 1 - 42TW Unit

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.

INTRODUCTION

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 CHECK

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.
