SAFETY CONSIDERATIONS
Installing and servicing air-conditioning equipment can be
hazardous due to system pressure and electrical components.
Only trained and qualified service personnel should install or
service air-conditioning equipment.
Untrained personnel can perform basic maintenance, such as
cleaning and replacing filters. All other operations should be
performed by trained service personnel. When working on air
conditioning equipment, observe safety precautions in litera-
ture, tags, and labels attached to unit.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for brazing operations. Have fire extin-
guisher available. Read these instructions thoroughly . Con-
sult local building codes and the National Electrical Code
(NEC) for special installation requirements.
GENERAL
These instructions cover the installation, start-up and service
of cooling only and heat pump duct-free systems.
INSTALLATION
I. STEP 1 — COMPLETE PRE-INSTALLATION CHECKS
A. Unpack Units (See Fig. 1)
Move the unit to final location. Remove unit from carton,
being careful not to damage service valves and grilles. See
Table 1A for installation materials included in shipment and
see Table 1B for field supplied materials needed to complete
the installation.
B. Inspect Shipment
File a claim with the shipping company if shipment is dam-
aged or incomplete. Check the unit nameplate to ensure unit
matches the job requirements.
C. Consider System Requirements
Consult local building codes and NEC for special installation
requirements. Use only designated indoor units with outdoor
units. See Tables 2 and 3.
WARNING:
Before installing or servicing system,
always turn off main power to system. There may be
more than one disconnect switch. Turn off accessory
heater power if applicable. Electrical shock can cause
serious personal injury.
CAUTION:
This system uses R-410A, which has
higher pressures than R-22 and other refrigerants. No
other refrigerant may be used in this system. All
equipment must be designed to handle R-410A refrig-
erant. If unsure about equipment, consult the equip-
ment manufacturer.
