All LX Compact Series product is safety listed under UL1995 thru ETL and performance listed

with AHRI in accordance with standard 13256-1.

LX COMPACT SERIES INSTALLATION MANUAL

Installing and servicing heating and air conditioning equipment

can be hazardous due to system pressure and electrical compo-

nents. 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 clean-

ing 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.

Follow all safety codes. Wear safety glasses and work gloves. Use

a quenching cloth for brazing operations and have a fire extin-

guisher available.

Moving and Storage

Move units in the normal “up” orientation. Horizontal units may

be moved and stored per the information on the packaging. Do

not stack more than three units in total height. Vertical units may

be stored one upon another to a maximum height of two units.

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.

Safety Considerations

General Installation Information

WARNING: Before performing service or maintenance

operations on a system, turn off main power switches

to the indoor unit. If applicable, turn off the accessory

heater power switch. Electrical shock could cause

personal injury.

Vertical Unit Mounting

2 in. PEX Foam

Unit Location

Locate the unit in an indoor area that allows for easy removal of

the filter and access panels. Location should have enough space

for service personnel to perform maintenance or repair. Provide

sufficient room to make water, electrical and duct connection(s). If

the unit is located in a confined space, such as a closet, provisions

must be made for return air to freely enter the space by means of a

louvered door, etc. Any access panel screws that would be difficult

to remove after the unit is installed should be removed prior to

setting the unit. On horizontal units, allow adequate room below

the unit for a condensate drain trap and do not locate the unit

above supply piping. Care should be taken when units are located

in unconditioned spaces to prevent damage from frozen water

lines and excessive heat that could damage electrical components.

Installing Vertical Units

Vertical units are available in left or right air return configurations.

Top flow vertical units should be mounted level on a vibration

absorbing pad slightly larger than the base to provide isolation

between the unit and the floor.

LX COMPACT SERIES INSTALLATION MANUAL

Installing Horizontal Units

Horizontal units are available with side or end discharge and may

be easily field converted by flipping the blower discharge panel.

Horizontal units are normally suspended from a ceiling by four 3/8

in. diameter threaded rods. The rods are usually attached to the

unit by hanger bracket kits furnished with each unit. Lay out the

threaded rods per the dimensions below. Assemble the hangers to

the unit as shown. Securely tighten the brackets to the unit using

the weld nuts located on the underside of the bottom panel. When

attaching the hanger rods to the bracket, a double nut is required

since vibration could loosen a single nut.

NOTE: The unit should be pitched approximately 1/4 in. towards

the drain in both directions to facilitate the removal of condensate.

Horizontal Unit Mounting

Use only the bolts provided in the kit to attach hanger brackets.

The use of longer bolts could damage internal parts. Some

applications require the installation of horizontal units on an attic

floor. In this case, the unit should be set in a full size secondary

drain pan on top of a vibration absorbing pad. The secondary

drain pan prevents possible condensate overflow or water leakage

damage to the ceiling. The secondary drain pan is usually placed

on a plywood base isolated from the ceiling joists by additional

layers of vibration absorbing material. Insulate supply plenum and

use at least one 90° elbow and flexible duct collar to reduce noise.

CAUTION: Do not use rods smaller than 3/8 in.

diameter since they may not be strong enough

to support the unit. The rods must be securely

anchored to the ceiling.
