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 distributor. 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 24 inches apart. (Coil face to coil face.
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 refrigerant charge shown in the nameplate is for standard size interconnecting liquid line lengths up to 15 feet. NOTE Using a larger than specified line size could result in oil return problems.
3.6 FACTORY-PREFERRED TIE-DOWN METHOD Step 1: Prior to installing clear pad of debris. IMPORTANT The pad must meet local codes and must be the proper thickness to accommodate fasteners. Step 2: Center and level unit onto pad. Step 3: Using field supplied L-shaped bracket to locate holes on concrete and drill pilot holes which is at least 1/4” deeper than fastener being used. IMPORTANT Self drilling screws to base pan should not exceed 3/8” long to avoid damaging coil.
3.7 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.
WEATHERPROOF DISCONNECT SWITCH TO POWER SUPPLY TO 24V c ontro INDOOR l sign al BLOWER TO COIL Seal opening(s) with permagum or equivalent NOTE:All outdoor wiring must be weather proof Fig.7 Typical Installation 3.8 PRECAUTIONS DURING BRAZING OF LINES All outdoor unit and evaporator coil connections are copper-to-copper and should be brazed with a phosphorous-copper alloy material such as Silfos-5 or equivalent. DO NOT use soft solder.
Connect the refrigerant lines using the following procedure: 1. Remove the cap and Schrader core from both the liquid and suction service valve service ports at the outdoor unit. Connect Iow pressure nitrogen to the liquid line service port. wet rag service valve Fig.8 Heat Protection 2. Braze the liquid line to the liquid valve at the outdoor unit. Be sure to wrap the valve body with a wet rag. Allow the nitrogen to continue flowing. Refer to the Tabular Data Sheet for proper liquid line sizing. 3.
10. Replace cap on service ports. Do not remove the flare caps from the service ports except when necessary for servicing the system. 11. Release the refrigerant charge into the system. Open both the liquid and suction valves by removing the plunger cap and with an hex wrench back out counter -clockwise until valve stem just touches the chamfered retaining wall. 12. Replace plunger cap finger tight, then tighten an additional 1/12 turn (1/2 hex flat). Cap must be replaced to prevent leaks.

6.0 ELECTRICAL CONNECTIONS 6.1 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 requirements. CAUTION All field wiring must USE COPPER CONDUCTORS ONLY and be in accordance with Local, National Fire, Safety & Electrical Codes.
6.3 REMOVING THE TOP PANEL AND MOTOR 1/2” nut NOTE: Damage will occur to condenser unit if you remove fan nuts prior to cover removal. 5/16” nuts Fig.10 COVER AND FAN When motor requires changing follow the steps below: Step 1: Go into electrical panel, disconnect motor power lines. IMPORTANT NOTE Disconnect main power to unit. Severe burns and electrical shock will occur if you do not disconnect main power.
5. Compare the measured LIQUID LINE PRESSURE to the TARGET LIQUID PRESSURE, add charge to raise the pressure or recover charge to lower it. 6. After running unit for 20 minutes if the SUCTION LINE PRESSURE changes, go back to step 2 otherwise remove test equipment and cover the valves. 7.2 CHARGING BY WEIGHT For a new installation,evacuation of interconnecting tubing and indoor coil is adequate; otherwise,evacuate the entire system.
9.
Orifice/TXV Replacement Information NOTE: The orifice / TXV replacement options noted in this sheet supersede those in the installation guide. Please reference this sheet for all refrigerant metering options. DRILL A SMALL HOLE IN VAPOR LINE FOR EQUALIZER TUBE Step 1: Remove the screws and front coil panel. BULB Step 2: Remove the rubber plugs from the liquid and vapor lines. Step 3: Using a back up wrench and loosen the flow assembly.
