PIPING INSTALLATION Refrigerant Piping CAUTION Use refrigeration grade piping ONLY. Uses of other piping will void the Manufacturer’s Warranty. Piping Preparation 1. Do not open service valves or remove protective caps on pipes until all connections are made. 2. Keep tubing free of dirt, sand, moisture and contaminants. 3. Insulate each refrigerant pipe and condensate hose with minimum 3/8” (10 mm) wall thermal pipe insulation. 4.

POWER AND WIRING INSTALLATION Indoor Unit Wire Connections WARNING Disconnect all electrical power to indoor and outdoor units including disconnects, fuses and circuit breakers. Lockout and tag all disconnect switches. 1. Open front cover of indoor unit and remove field wiring terminal block cover. 2. Pull interconnecting wires up from back of indoor unit and position in close to the terminal block on indoor unit.
POWER AND WIRING INSTALLATION Outdoor Unit Wire Connections WARNING Disconnect all electrical power to unit including disconnects, fuses and circuit breakers. Lockout and tag all disconnect switches. 1. Remove the service panel on right side of the outdoor unit. 2. Insert interconnecting wires and main power wires through the wire holes on conduit mounting bracket. Cable Cross Board 3. Secure main power conduit (and interconnecting wire conduit, if required) with locking nuts to conduit mounting bracket.
TESTING AND INSPECTION Leaking Test 1. Connect the charging hose of the manifold valve to charge the end of the low-pressure valve. 2. Add dry nitrogen to a pressure of 200 lbs. Tightly close both high- and low-pressure valves. 3. Leak-test flare fittings with soap bubbles. If no leak is detected, release nitrogen. CAUTION Use vacuum pump, rather than refrigerant, to discharge air when installing the unit.
TESTING AND INSPECTION Vacuum Procedure (con’t) 7. Confirm that manifold valves are closed and disconnect the vacuum pump. 8. Open the service valves to the fully ‘back-seat’ position to let the refrigerant flow to the indoor unit and balance the pressure in system. Important: Do not allow air to enter the connection pipe when removing the hose. 9. Replace service valve caps and tighten.
TESTING AND INSPECTION Condensate Drain Pipe Testing Carefully and slowly add 8-10 ounces of water to the indoor unit drain pan. • Verify the water drains easily out the condensate drain hose. • If water does not drain easily from the drain hose, then remove kinks, increase drain pitch, or add an auxiliary condensate drain pump. Start-up Checklist □ Turn on main power to indoor and outdoor units. • Verify the system is not displaying an error code on the indoor unit display.
TROUBLESHOOTING PROBLEM CAUSE/SOLUTION System does not restart. Cause: The system has a built-in three-minute delay to prevent short and/or rapid cycling of the compressor. Solution: Wait three minutes for the protection delay to expire. Indoor unit emits unpleasant odor when started Cause: Typically unpleasant odors are the result of mold or mildew forming on the coil surfaces or the air filter. Solution: Wash indoor air filter in warm water with mild cleaner.
TROUBLESHOOTING PROBLEM CAUSE/SOLUTION Water leakage from the outdoor unit. Cause: It is normal for the outdoor unit to generate condensate water in the reverse cycle heating and defrost mode. Solution: This is normal. No action is required. The unit is not heating or cooling adequately. Wireless remote controller does not work. Cause: There are a number of reasons for inadequate cooling or heating. Solution: Check the following: • Remove obstructions blocking airflow into the room.
DIAGNOSTIC CODES Troubleshooting The Livv System has onboard diagnostics. The outdoor unit will provide status indicators. The indoor wall unit and remote controller will display error codes. The following is a summary of the codes with explanation: Malfunction Name Indoor Unit & Remote Display Outdoor Unit Indicators Yellow Red Possible Causes 1) Over charged with refrigerant. 2) Blocked or dirty outdoor coil .
DIAGNOSTIC CODES Malfunction Name Indoor Unit & Remote Display IPM Module Protection H5 Indoor DC Fan Motor Malfunction H6 1) Loose connections between fan motor and control board 2) Fan motor or blower wheel bearings malfunction. 3) Control board malfunction. Compressor De-Synchronized Malfunction H7 1) Compressor voltage is not balance.
CARE AND CLEANING WARNING Take notice of the following items before cleaning the Livv Indoor wall unit. • To avoid electric shock or injury, do not attempt to clean the unit unless it has been turned off and disconnected from the main power supply. • Do not wash the unit with water; this may cause an electric shock. • During cleaning, be sure to use a stable standing platform. Air Filter Cleaning Changing your air filter on a regular basis prevents many problems.
