1.2 LIMITATIONS
The unit should be installed in accordance with all National, State and Local Safety Codes and the limitations listed below:
1.Limitations for the indoor unit, coil and appropriate accessories must also be observed.
2.The outdoor unit must not be installed with any duct work in the air stream. The outdoor fan is the propeller type and is not designed to operate against any additional external static pressure.
3.The maximum and minimum conditions for operation must be observed to assure a system that will give maximum performance with minimum service.
4.The maximum allowable line length for this product is 150 feet.
2.0 GENERAL
The outdoor units are designed to be connected to a matching indoor coil with sweat connect lines. Sweat connect units are factory charged with refrigerant for a match­ing indoor coil plus 25 feet of field supplied lines.
Matching indoor coils are available with a thermostatic expansion valve or an orifice for the most common usage. The orifice size and/or refrigerant charge may need to be changed for some indoor-outdoor unit combinations, elevation differences or total line lengths.
Before installation a load calculation must be performanced by the installer, as well as a duct analysis. Proper sizing and coil/air handler matching are the installer’s responsibilities to ensure compliance.

3.0 UNIT INSTALLATION
3.1 LOCATION
Before starting the installation, select and check the suitability of the location for both the indoor and outdoor unit. Observe all limitations and clearance requirements. The outdoor unit must have sufficient clearance for air entrance to the condenser coil, for air discharge and for service access. See Fig.2
NOTE
For multiple unit installations, units must be spaced a minimum of 18 inches apart. (Coil face to coil face.)
If the unit is to be installed on a hot sun exposed roof or a black-topped ground area, the unit should be raised sufficiently above the roof or ground to avoid taking the accumu­lated layer of hot air into the outdoor unit.
Provide an adequate structural support.
3.2 GROUND INSTALLATION
The unit may be installed at ground level on a solid base that will not shift or settle, caus­ing strain on the refrigerant lines and possible leaks. Maintain the clearances shown in Fig.2 and install the unit in a level position.
Normal operating sound levels may be objectionable if the unit is placed directly under windows of certain rooms (bedrooms, study, etc.). Top of unit discharge area must be unrestricted for at least 60 inches above the unit.
WARNING
The outdoor unit should not be installed in an area where mud or ice could cause personal injury.
Elevate the unit sufficiently to prevent any blockage of the air entrances by snow in areas where there will be snow accumulation. Check the local weather bureau for the expected snow accumulation in your area. Isolate the unit from rain gutters to avoid any possible wash out of the foundation.
3.3 ROOF INSTALLATION
When installing units on a roof, the structure must be capable of supporting the total weight of the unit, including a padded frame unit, rails, etc., which should be used to minimize the transmission of sound or vibration into the conditioned space.
3.4 UNIT PLACEMENT
1. Provide a base in the pre-determined location.
2. Remove the shipping carton and inspect for possible damage.
3. Compressor tie-down bolts should remain tightened.
4. Position the unit on the base provided.
9
CAUTION
This system uses R410A refrigerant which operates at higher pressure than R-22. No other refrigerant may be used in this system. Gauge sets, hoses, refrigerant containers, and recovery system must be designed to handle R410A. If you are unsure, consult the equipment manufacturer.
The outdoor unit must be connected to the indoor coil using field supplied refrigerant grade copper tubing that is internally clean and dry. Units should be installed only with the tubing sizes for approved system combinations. The charge given is applicable for total tubing lengths up to 25 feet.
NOTE
Using a larger than specified line size could result in oil return problems. Using too small a line will result in loss of capacity and other problems caused by insuf­ficient refrigerant flow. Slope horizontal vapor lines at least 1" every 20 feet toward the outdoor unit to facilitate proper oil return.
3.5 PRECAUTIONS DURING LINE INSTALLATION
1. Install the lines with as few bends as possible. Care must be taken not to damage the couplings or kink the tubing. Use clean hard drawn Copper tubing where no appreciable amount of bending around obstruction is necessary, if soft copper must be used, care must be taken to avoid sharp bends which may cause a restriction.
2. The lines should be installed so that they will not obstruct service access to the coil, air handling system or filter.
3. Care must also be taken to isolate the refrigerant lines to minimize noise transmis­ sion from the equipment to the structure.
4. The vapor line and liquid line must be insulated with a minimum of 1/2" foam rubber insulation (Armafiex or equivalent). Tape and suspend the refrigerant lines as shown. DO NOT allow tube metal-to-metal contact. See Fig. 3.
5. Use PVC piping as a conduit for all underground installations as shown in Fig. 4. Buried lines should be kept as short as possible to minimize the build up of liquid refrigerant in the vapor line during long periods of shutdown.
6. Pack fiberglass insulation and a sealing material such as perma gum around refrig­ erant lines where they penetrate a wall to reduce vibration and to retain some flexi­ bility.
