SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service,

maintenance, or use can cause explosion, fire, electrical shock,

or other conditions which may cause death, personal injury or

Take precaut ions t o ensure Aluminum tubes do not come in

dir ect contact or all ow for condensate run of f wit h a dissimilar

metal. Dissimi lar metals can cause galvanic cor r osi on and

possible premature failure.

CAUTION

EXPLOSION HAZARD

Failure to follow this warning could result

in death, serious personal injury, and/or

property damage.

Never use air or gases containing

oxygen for leak testing or operating

refrigerant compressors. Pressurized

mixtures of air or gases containing

oxygen can lead to an explosion.

WARNING

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. INSTALLATION INTRODUCTION File claim with shipper if equipment is damaged. Use this instruction manual to install EAM4X & WLAM indoor coils on multipoise furnaces. EAM4X & WLAM models are enclosed in a casing.
PAGE 3
NOTE: On upflow installations where the indoor coil is placed in an unconditioned space, a 6” wide piece of insulation should be applied and wrapped around the outside of coil casing and supply duct contact point.

Use self- tapping screws to attach furnace. (See Figure 5) 5. Seal joint between coil casing and furnace to create an air tight seal using locally approved materials. 6. Use cork tape to create air seal between the undersides of the pan extension and front of the vertical drain pan as shown in Figure 6. 7.

! CAUTION UNIT OR PROPERTY DAMAGE HAZARD Failure to follow this caution may result in property damage. Take precautions to ensure Aluminum tubes do not come in direct contact or allow for condensate run off with a dissimilar metal. Dissimilar metals can cause galvanic corrosion and possible premature failure. Unbend tab as shown, 4 places.

! CAUTION UNIT DAMAGE HAZARD Failure to follow this caution may result in product damage. DO NOT BURY MORE THAN 36 IN. OF REFRIGERANT TUBING IN GROUND. If any section of tubing is buried, there must be a 6 in. vertical rise to the valve connections on the outdoor unit. If more than the recommended length is buried, refrigerant may migrate to cooler buried section during extended periods of unit shutdown, causing refrigerant slugging and possible compressor damage at start- up.
