C4H5S, H4H5S, T4H5S: Installation Instructions
Fig. 1 – Connecting Tubing Installation
When outdoor unit is connected to factory–approved indoor unit,
outdoor unit contains system refrigerant charge for operation with AHRI
rated indoor unit when connected by 15 ft. (4.57 m) of field–supplied or
factory accessory tubing. For proper unit operation, check refrigerant
charge using charging information located on control box cover and/or
in the Check Charge section of this instruction.
IMPORTANT: Maximum liquid–line size is 3/8–in. OD for all
residential applications including long line.
IMPORTANT: Always install the factory–supplied liquid–line filter
drier. Obtain replacement filter driers from your distributor or branch.
INSTALLATION
IMPORTANT: All split system and packaged air conditioners must be
installed pursuant to applicable regional efficiency standards issued by
the Department of Energy.
CAUTION
!
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and wear
appropriate protective clothing and gloves when handling parts.
Check Equipment and Job Site
Unpack Unit
Move to final location. Remove carton taking care not to damage unit.
Inspect Equipment
File claim with shipping company prior to installation if shipment is
damaged or incomplete. Locate unit rating plate on unit corner panel. It
contains information needed to properly install unit. Check rating plate
to be sure unit matches job specifications.
Install on a Solid, Level Mounting Pad
If conditions or local codes require the unit be attached to pad, tie down
bolts should be used and fastened through knockouts provided in unit
base pan. Refer to unit mounting pattern in
size and knockout hole location.
For hurricane tie downs, contact distributor for details and PE
Certification (Professional Engineer), if required.
On rooftop applications, mount on level platform or frame. Place unit
above a load–bearing wall and isolate unit and tubing set from structure.
Arrange supporting members to adequately support unit and minimize
transmission of vibration to building. Consult local codes governing
rooftop applications.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

Roof mounted units exposed to winds above 5 mph may require wind
baffles. Consult the Service Manual – Residential Split System Air
Conditioners and Heat Pumps for wind baffle construction.
Unit must be level to within ±2° (±3/8 in/ft,±9.5 mm/m) per compressor
manufacturer specifications.
Clearance Requirements
When installing, allow sufficient space for airflow clearance, wiring,
refrigerant piping, and service. Allow 24 in. (609.6 mm) clearance to
service end of unit and 48 in. (1219.2 mm) above unit. For proper
airflow, a 6–in. (152.4 mm) clearance on 1 side of unit and 12–in. (304.8
mm) on all remaining sides must be maintained. Maintain a distance of
24 in. (609.6 mm) between units or 18 in. (457.2 mm) if no overhang
within 12 ft. (3.66 m). Position so water, snow, or ice from roof or eaves
cannot fall directly on unit.
18" (457.2 mm) clearance option described above is approved for
outdoor units with wire grille coil guard only. Units with louver panels
require 24" (609.6 mm) between units.
On rooftop applications, locate unit at least 6 in. above roof surface.

UNIT OPERATION HAZARD
Failure to follow this caution may result in equipment damage or
improper operation.
Do not allow water and/or ice to build up in base pan.
Elevate unit per local climate and code requirements to provide
clearance above estimated snowfall level and ensure adequate drainage
of unit.
