SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service, maintenance, or use can cause explosion, fire, electrical shock, or other conditions; which may cause death, personal injury or property damage. The qualified installer or agency must use factory-authorized kits or accessories when modifying this product.

Follow all safety codes. Wear safety glasses, protective clothing, and work gloves. Use quenching cloth for brazing operations. Have fire extinguisher available. Read these instructions thoroughly and follow all warnings or cautions included in literature and attached to the unit. Consult local building codes and the current editions of the National Electrical Code (NEC) ANSI/NFPA (American National Standards Institute/National Fire Protection Association) 70. In Canada, refer to the current editions of the Canadian Electrical Code CSA (Canadian Standards Association) C22.1.

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 result in minor personal injury or product and property damage.

Recognize safety information. This is the safety-alert symbol ( ). When this symbol is displayed on the unit and in instructions or manuals, be alert to the potential for personal injury. Installing, starting up, and servicing equipment can be hazardous due to system pressure, electrical components, and equipment location.

WARNING

Electrical shock can cause personal injury and death. Shut off all power to this equipment during installation. There may be more than one disconnect switch. Tag all disconnect locations to alert others not to restore power until work is completed.

Manufacturer reserves the right to discontinue, or change at any time, specifications or desi gns without notice and wit hout incurring obligations.

CAUTION

When installing the equipment in a small space, provide adequate measures to avoid refrigerant concentration exceeding safety limits due to refrigerant leak. In case of refrigerant leak during installation, ventilate the space immediately. Failure to follow this procedure may lead to personal injury.

WARNING

DO NOT USE TORCH to remove any component. System contains oil and refrigerant under pressure.

To remove a component, wear protective gloves and goggles and proceed as follows:

a. Shut off electrical power to unit. b. Recover refrigerant to relieve all pressure from

system using both high-pressure and low pressure ports.

c. Traces of vapor should be displaced with nitrogen

and the work area should be well ventilated. Refrigerant in contact with an open flame produces toxic gases.

d. Cut component connection tubing with tubing cutter

and remove component from unit. Use a pan to catch any oil that may come out of the lines and as a gage for how much oil to add to the system.

e. Carefully unsweat remaining tubing stubs when

necessary. Oil can ignite when exposed to torch flame.

Failure to follow these procedures may result in personal injury or death.

DO NOT re-use compressor oil or any oil that has been exposed to the atmosphere. Dispose of oil per local codes and regulations. DO NOT leave refrigerant system open to air any longer than the actual time required to service the equipment. Seal circuits being serviced and charge with dry nitrogen to prevent oil contamination when timely repairs cannot be completed. Failure to follow these procedures may result in damage to equipment.

GENERAL

The VRF (variable refrigerant flow) Heat Pump system offers a variety of indoor unit types and sizes, ranging from 0.5 to 8 tons. The 38VMA Heat Pump outdoor units are available in four capacities, 6, 8, 10, and 12 tons. Units can be combined to accommodate larger capacity requirements. The system has capability to operate between 50% and 135% connected capacity, allowing the system to be tailored to the needs of the customer and the application.

The equipment is initially protected under the manufacturer’s standard warranty; however, the warranty is provided under the condition that the steps outlined in this manual for initial inspection, proper installation, regular periodic maintenance, and everyday operation of the unit be followed in detail. This manual should be fully reviewed in advance before initial installation, start-up, and maintenance. Contact your local sales representative or the factory with any questions BEFORE proceeding.

See Fig. 1 for model number nomenclature. Table 1 shows components that may or may not be used for a particular installation. T able 2 lists physical data for each unit size. Tables 3-6 list physical data for combination units. Figure 2 shows unit dimensions.

** The amount does not consider extra piping length. Refrigerant

must be added on site in accordance with the actual piping length. †† Select wire size based on larger value of MCA. *** In case the diversity exceeds 135%, the type of indoor unit is

limited and the maximum number of indoor unit is reduced. ††† These values, measured in anechoic chamber, at a point 1 m in

front of the unit at a height of 1.4 m. During actual operation,

these values are normally somewhat higher as a result of ambient

conditions.
