INSTALLATION
Step 1 — Unpack and Inspect Unit
Remove shipping wraps from unit and check shipment against 
shipping list. Check for concealed shipping damage. If ship-
ment is damaged or incomplete, file claim with transportation 
company and contact your local Carrier representative 
immediately.
Step 2 — Protect Unit from Damage
To maintain warranty, protect unit against adverse weather condi-
tions, theft or vandalism on the jobsite.
The described equipment IS NOT suitable for outdoor installa-
tions. The equipment should never be stored or installed where it 
may be subjected to a hostile environment such as rain, snow, or 
extreme temperatures.
Step 3 — Prepare Jobsite
To save time and to reduce the possibility of costly errors, set up a 
complete sample installation in a typical room at jobsite. Check all 
critical dimensions such as pipe, wire and duct connection require-
ments. Refer to job drawings and product dimension drawings as 
required. Instruct all trades in the appropriate part of the installa-
tion. For unit component identification, refer to Fig. 2. For unit di-
mensions, refer to Fig. 3-5 for 42BHE units. Refer to Fig. 6-8 for
