USER INFORMATION

IMPORTANT SAFETY INFORMATION

Safety markings are used frequently throughout this manual to designate a degree or level of seriousness and should not be ignored. WARNING indicates a potentially hazardous situation that if not avoided, could result in personal injury or death. CAUTION indicates a potentially hazardous situation that if not avoided, may result in minor or moderate injury or property damage.

OPERATING INSTRUCTIONS

NOTE: Thermostat styles vary. Some models may not

include the AUTO mode and others will have the AUTO in place of the HEAT and COOL. Others may include all three. Please refer to the thermostat manufacturer’s User manual for detailed programming instructions.

Cooling Operation

1. Set the thermostat’s system mode to COOL or AUTO and change the fan mode to AUTO. See Figure 1

2. Set the temperature selector to the desired temperature level. The outdoor fan, compressor, and blower motor will all cycle on and off to maintain the indoor temperature at the desired cooling level.

NOTE: If the temperature level is re-adjusted, or the system mode is reset, the fan and compressor in the outdoor unit may not start immediately. A protective timer circuit holds the compressor and the outdoor fan off for approximately 5 minutes following a previous operation or the interruption of the main electrical power.

Heating Operation

1. Set the thermostat’s system mode to HEAT or AUTO and change the fan mode to AUTO. See Figure 1.

2. Set the temperature selector to the desired temperature level. The optional heating equipment (furnace or electric heat) will cycle on & off to maintain the indoor temperature at the desired heating level.

Operating the AC for Automatic Cooling & Heating

1. Set the thermostat system mode to AUTO and the thermostat fan mode to AUTO. See Figure 1.

2. Set the thermostat temperature selector to the desired temperature level. The thermostat will maintain the desired temperature level by switching between either the outdoor cooling unit or the indoor heating unit (furnace or electric heat) automatically.

Operating the Indoor Blower Continuously

The continuous indoor blower operation is typically used to circulate the indoor air to equalize a temperature unbalance due to a sun load, cooking, or ﬁ replace operation. Set the thermostat fan mode to ON (Figure 1). The indoor blower starts immediately, and will run continually until the fan mode is reset to AUTO.

The continuous indoor blower operation can be obtained with the thermostat system mode set in any position, including OFF.

Turning the Air conditioner Off

Change the thermostat’s system mode to OFF and the fan mode to AUTO (See Figure 1). NOTE: The system will not operate, regardless of the temperature selector setting.

AIR CONDITIONER INSTALLATION

General Information

The S5BP series air conditioner is designed only for outdoor rooftop or ground level installations. This unit has been tested for capacity and efﬁ ciency in accordance with A.R.I. Standards and will provide many years of safe and dependable comfort, providing it is properly installed and maintained. Abuse, improper use, and/or improper maintenance can shorten the life of the appliance and create unsafe hazards.

To achieve optimum performance and minimize equipment failure, it is recommended that periodic maintenance be performed on this unit. The ability to properly perform maintenance on this equipment requires certain mechanical skills and tools.

Before you install this unit

 The cooling load of the area to be conditioned must be

calculated and a system of the proper capacity selected. It is recommended that the area to be conditioned be completely insulated and vapor sealed.

 Check the electrical supply and verify the power supply

is adequate for unit operation. The system must be wired and provided with circuit protection in accordance with local building codes. If there is any question concerning the power supply, contact the local power company.

 The indoor section (air handler, furnace, etc) should be

installed before routing the refrigerant tubing. Refer to the indoor unit's installation instructions for installation details.

 All units are securely packed at the time of shipment and

upon arrival should be carefully inspected for damage prior to installing the equipment at the job site. Verify coil ﬁ ns are straight. If necessary, comb ﬁ ns to remove ﬂ attened or bent ﬁ ns. Claims for damage (apparent or concealed) should be ﬁ led immediately with the carrier.

 Please consult your dealer for maintenance information

and availability of maintenance contracts. Please read all instructions before installing the unit.

Locating the Air Conditioner

• Survey the job site to determine the best location for mounting the outdoor unit.

• Overhead obstructions, poorly ventilated areas, and areas subject to accumulation of debris should be avoided.

• Sufﬁ cient clearance for unobstructed airﬂ ow through the outdoor coil must be maintained in order to achieve rated performance. See Figure 2 for minimum clearances to obstructions.

• Consideration should be given to availability of electric power, service access, noise, and shade.

load. Refer to Table 3 (page 12) for unit weights.

• The unit must be lifted from the holes in the

base rails using cables or chains.

• Spreader bars are required to protect the unit

and ensure even loading.

• Keep the unit in an upright position at all times.

• All panels must be securely in place during

rigging and hoisting.

Rooftop

Rooftop installations must be located according to local building codes or ordinances and these requirements:

• Units may be installed on Class A, B, or C roof covering material. The roof must be capable of handling the weight of the unit. For unit weights, see Table 3 (page

12). Reinforce the roof if necessary.

• Secure optional mounting pad or frame to roof using acceptable mechanical methods per local codes.
