This document is customer property and is to remain with this unit. These instructions do not cover all the different variations of systems nor does it provide for every possible contingency to be met in connection with installation. All phases of this installation must comply with NATIONAL STATE AND LOCAL CODES. If additional information is required please contact your local distribu tor. 1.0 SAFETY This is a safety alert symbol.
1.1 INSPECTION As soon as a unit is received, it should be inspected for possible damage during transit. If damage is evident, the extent of the damage should be noted on the carrier's delivery receipt. A separate request for inspection by the carrier's agent should be made in writing. See Local distributor for more information. Requirements For Installing/Servicing R410A Equipment Gauge sets, hoses, refrigerant containers, and recovery system must be designed to handle the POE or PVE type oils.

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.
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.

CAUTION Dry nitrogen should always be supplied through the tubing while it is being brazed, because the temperature required is high enough to cause oxidation of the copper unless an inert atmosphere is provide. The flow of dry nitrogen should continue until the joint has cooled. Always use a pressure regulator and safety valve to insure that only low pressure dry nitrogen is introduced into the tubing.Only a small flow is necessary to displace air and prevent oxidation. 3.

4.0 ELECTRICAL CONNECTIONS 4.1 GENERAL INFORMATION & GROUNDING Check the electrical supply to be sure that it meets the values specified on the unit nameplate and wiring label. Power wiring, control (Iow voltage) wiring, disconnect switches and over current protection must be supplied by the installer. Wire size should be sized per req-uire ments. CAUTION All field wiring must USE COPPER CONDUCTORS ONLY and be in accordance with Local, National Fire, Safety & Electrical Codes.
5.0 EVACUATION It will be necessary to evacuate the system to 500 microns or less. If a leak is suspected, leak test with dry nitrogen to locate the leak. Repair the leak and test again. To verify that the system has no leaks, simply close the valve to the vacuum pump suction to isolate the pump and hold the system under vacuum. Watch the micron gauge for a few minutes. If the micron gauge indicates a steady and continuous rise, it's an indication of a leak.

7.3 PROTECTION FUNCTION INTRODUCTION (Heat pump only Sensor T3 (condenser pipe temperature) and T4 (outdoor ambient temperature) When open-circuit, compressor, outdoor fan motor and reverse valve will be OFF. When T4 < 5 °F, compressor will stop.If the electrical heater kit is installed in the indoor unit, the outdoor unit would provide a signal to drive up the heater. When T4 > 10.4 °F, compressor will restart Discharge temperature protection When discharge temp. > 275 °F, compressor will stop.
8.0 CHECKING REFRIGERANT CHARGE Charge for all systems should be checked against the Charging Chart inside the access corner panel. IMPORTANT:Do not operate the compressor without charge in system. Additio n of R - 410A will raise pressures (vapor, liquid and discharge). If adding R - 410A raises both vapor pressure and temperature, the unit is over c harged. - IMPORTANT: Use industry - approved charging methods to ensure proper system charge. 8 .
9.1 MAINTENANCE 1.. Dirt should not be allowed to accumulate on the outdoor coils or other parts in the air circuit. Clean as often as necessary to keep the unit clean. Use a brush, vacuum cleaner attachment, or other suitable means. 2. The outdoor fan motor is permanently lubricated and does not require periodic oiling. 3. If the coil needs to be cleaned, it should be washed with Calgon Coilclean (mix one part Coilclean to seven parts water).
