SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical components.
Only trained and qualified service personnel should install,
repair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance func-
tions of cleaning coils and filters and replacing filters. All other
operations should be performed by trained service personnel.
When working on air-conditioning equipment, observe precau-
tions in the literature, tags and labels attached to the unit, and
other safety precautions that may apply.
Improper installation, adjustment, alteration, service, mainte-
nance, or use can cause explosion, fire, electrical shock or other
conditions which may cause personal injury or property
damage. Consult a qualified installer, service agency, or your
distributor or branch for information or assistance. The qualified
installer or agency must use factory-authorized kits or accesso-
ries when modifying this product. Refer to the individual
instructions packaged with the kits or accessories when
installing.
Follow all safety codes. Wear safety glasses and work
gloves. Use quenching cloth for brazing operations. Have fire
extinguisher available. Read these instructions thoroughly and
follow all warnings or cautions attached to the unit. Consult
local building codes and applicable electrical codes for special
installation requirements.
Understand the signal words - DANGER, WARNING, and
CAUTION. DANGER identifies the most serious hazards
which will result in severe personal injury or death. WARNING
signifies hazards that could result in personal injury or death.
CAUTION is used to identify unsafe practices, which would re-
sult in minor personal injury or product and property damage.

    1. Adjust all valves to the full open position and turn on the line power to all heat pump units. 2. Operate each unit in the Cooling mode first. Room temperature should be in the normal range (i.e., approximately 10.0 to 26.7 C dry bulb).

    16 C and 35 C. 5. Two factors determine the operating limits of Carrier heat pumps, return air temperature and water temperature. When any one of these factors is at a minimum or maxi- mum level, the other factor must be at normal level to en- sure proper unit operation.

  • Page 32: Cooling Tower/Boiler Systems

    Cooling Tower/Boiler Systems — typically use a common loop maintained at 15.6 C to 32.2 C. Carrier recommends using a closed circuit evaporative cooling tower with a secondary heat exchanger between the tower and the water loop. If an open type cooling tower is used continu- ously, chemical treatment and filtering will be necessary.
