General Installation Information

Safety Considerations

WARNING: Before performing service or maintenance operations on a system, turn off main power switches to both units. Turn off accessory heater power switch if applicable. Electrical shock could cause personal injury. Installing and servicing heating and air conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified ser- vice personnel should install, repair or service heating and air conditioning equipment.

Installing and servicing heating and air conditioning equipment can be hazardous due to system pressure and electri- cal components. Only trained and qualified service personnel should install, repair or service heating and air conditioning equipment. Untrained personnel can perform the basic maintenance functions of cleaning coils and cleaning and replacing filters. All other operations should be performed by trained service personnel. When working on heating and air conditioning equipment, observe precautions in the literature, tags and labels attached to the unit and other safety precautions that may apply, such as the following safety measures:

Follow all safety codes.

Wear safety glasses and work gloves.

Use a quenching cloth for brazing operations.

Have a fire extinguisher available for all brazing operations.

Moving and Storage

Move units in the normal “up” orientation. Units may be moved and stored per the information on the packaging. Do not stack more than three units in total height. Do not attempt to move units while stacked. When the equipment is received, all items should be carefully checked against the bill of lading to be sure all crates and cartons have been received. Examine units for shipping damage, removing the units from the packaging if necessary. Units in question should also be internally inspected. If any damage is noted, the carrier should make the proper notation on the delivery receipt, acknowledging the damage.

Split Unit Location

Locate the split compressor section away from areas that may disturb the customer and in a way that allows easy re- moval of the access panels and the top of the cabinet. Provide sufficient room to make water, electrical and refrigerant line connections and allow space for service personnel to perform maintenance. The NS split is approved for outdoor installation when properly installed.

Air Coil Location

Refer to the air handler manufacturer’s instructions for the blower coil unit for details on installing the air handling portion of the system.

Condensate Drain

Follow the blower coil manufacturer’s instructions.

Duct System

All blower coil units/air coils must be installed as specified by the manufacturer’s installation instructions; however, the following recommendations should considered to minimize noise and service problems.

An air filter must always be installed upstream of the air coil on the return air side of the air handler or furnace. If there is limited access to the filter rack for normal maintenance, it is suggested that a return air filter grill be installed. Be sure that the return duct is properly installed and free of leaks to prevent dirt and debris from bypassing the filter and plugging the air coil.

In applications using galvanized metal ductwork, a flexible duct connector is recommended on both the supply and return air plenums to minimize vibration from the blower. To maximize sound attenuation of the unit blower, the supply and return plenums should include an internal duct liner of 1-inch thick glass fiber or be constructed of ductboard. Insulation is usually not installed in the supply branch ducts. Ducts in unconditioned areas should be wrapped with a minimum of 1-inch duct insulation. Application of the unit to uninsulated ductwork in an unconditioned space is not recommended as the unit’s performance will be adversely affected. If the air handler is connected to existing ductwork, a previous check should have
