Specifications subject to change without notice.
IMPORTANT: Nitrogen can leak out through the hole that the
needle pierced in the plugs. This does not indicate a leaking
coil nor warrant return of the coil.
INTRODUCTION
Use this instruction manual to install EAM4X & WLAM indoor
coils on multipoise furnaces. EAM4X & WLAM models are
enclosed in a casing.

INSTALLATION OF EVAPORATOR COILS
Upflow coil installation
The c ased coil is designed to fit furnaces of the same width.
1. Set c oil in place on upflow furnace discharge air
opening.
2. Ensure coil is level for proper condensate drainage. Do
not tip coil toward condensate drain. Coil casing need
not be fastened or screwed to furnace.
3. When installing wider coil on narrow furnace, create field
fabricated adapter. (See Figure 2)
