3 General

The evaporator of indoor unit is charged with refrigerant in factory for pressure

maintaining. The cut-off valve can be opened only when installation and vacuuming is

done.

The drain pan must be at least 2" away from a standard gas-fired furnace heat

exchanger and at least 4"-6" away from any drum-type or oil-fired furnace heat

exchanger, depending on furnace model. Closer spacing may damage the drain pan

and cause a leak.

Refer to the Product Specification for the proper use of these coils with specific

furnaces, air handlers, condensers and line sets.

4.1.3 Codes & Regulations

This product is designed and manufactured to comply with national codes. It is

installer’s responsibilities to install the product in accordance with such codes and/or

any prevailing local codes/regulations. The manufacturer assumes no responsibilities

for equipment installed in violation of any codes or regulations.

These instructions are intended as a general guide and do not supersede local or

national codes in any way. Authorities who have jurisdiction should be consulted before

installation.

4.1.4 Replacement Parts

When reporting shortages or damages, or ordering repair parts, give the complete

product model and serial numbers as stamped on the product. Replacement parts for

this product are available through your contractor or local distributor.

4.2 Location

This coil is designed for indoor installation only. Do not install it

outdoors.

Not suitable for use with ammonia.

When installing the coil, take consideration to minimize the length of refrigerant

tubing as much as possible. Do not install the air handler in a location either above or

below the condenser that violates the instructions provided with the condenser. Service

clearance is to take precedence. Allow a minimum of 25” in front of the unit for service

clearance, as shown below.

A-Coil

When installing in an area directly over a finished ceiling (such as an attic), an

emergency drain pan is required directly under the unit. See local and state codes for

requirements. When installing this unit in an area that may become wet, elevate the unit

with a sturdy, non-porous material. In installations that may lead to physical damage (i.e.

a garage) it is advised to install a protective barrier to prevent such damage.

It is necessary to allow a minimum of 40” between the inlet/outlet of the indoor unit

and wall, as shown below.
