Installation (1) Installation Of VCU • The unit should be installed in accordance with all national and local codes and regulations which govern the installation of this type of equipment. • The VCU unit must not be installed with any duct work on the air discharge side. The outdoor fan is a propeller type and is not designed to operate against any additional external static.
Piping Sizes (Brazed Valve) Piping sizes are as follows: MODEL Liquid (mm/in) Suction (mm/in) MVCU 025A 9.52 (3/8) 15.88 (5/8) MVCU 030A 9.52 (3/8) 15.88 (5/8) MVCU 035 / 040A 9.52 (3/8) 19.05 (3/4) MVCU 050A 9.52 (3/8) 19.05 (3/4) MVCU 060A 12.7 (1/2) 22.23 (7/8) (3) Wiring Electrical Connections • Wiring regulations on wire diameters differ from country to country. Please refer to your LOCAL ELECTRICAL CODES for field wiring rules. Be sure that installation comply with such rules and regulations.
(5) Additional Charge • The refrigerant gas has already charged into the outdoor unit. For the piping length of 5m. Additional refrigerant charge after vacuuming is not necessary. • When the piping length is more than 5m, please use the table below (unit in gram).

Service And Maintenance Warning: Disconnect from main supply before servicing the air conditioner. The unit is designed to give long life operation with minimum maintenance required. However, it should be regularly checked and the following items should be given due attention. Components Air filter (Indoor Unit) Indoor unit Condense Drain Pan & Pipe Indoor Fan Maintenance Procedure 1. Remove the ionizer filter before cleaning the filter. 2.
The design of the VCU outdoor series allows servicing to be carried out readily and easily. The removal of the top side, front and back panel make almost every part accessible. Under normal circumstances, these outdoor units only require a check and cleaning of air intake coil surface once quarterly.
Troubleshooting When any air-conditioner malfunction is noted, immediately switch off the power supply to the unit, and contact the local dealer, if necessary. Some simple troubleshooting tips are given below : FAULT CAUSE 1. Fan does not work 3 minutes after starting • Protection against the frequent starting. Wait 3 or 4 minutes. 2. The air conditioning unit does not work • Power failure or you must be replaced the fuse. • The power plug is disconnected.
FOR COOLING ONLY MODELS DIAGNOSIS BY FLOW CHART The following chart are efficient checking procedures for troubleshooting when these fan-coil units are coupled with the condensing units using standard wiring. For dual circuited models, perform the procedures for each circuit.
