Special Precautions for R407 Special Precautions When Dealing With Refrigerant R407C Unit 1) What is new refrigerant R407C? R407C is a zeotropic refrigerant mixture which has Zero Ozone Depletion Potential (ODP = 0) and thus conformed to the Montreal Protocol regulation. It requires Polyol-ester oil (POE) oil for its compressor's lubricant. Its refrigerant capacity and performance are about the same as the refrigerant R22.
c) Ensure that the compressor is not expose to open air for more than the recommended time specified by its manufacturer (typically less than 10 minutes). Removed the seal-plugs only when the compressor is about to be brazed. d) The system should be thoroughly vacuumed to 1.0 Pa (-700mmHg) or lower. This vacuuming level is more stringent than R22 system so as to ensure no incompressible gas and moisture in the system.
Installation Cautio Caution Sharp edges and coil surfaces are potential injury hazard. Avoid from contact with them. (1) Installation of Outdoor Unit Preliminary Site Survey • Electrical supply and installation is to conform to local authority's (e.g. National Electrical Board) codes and regulations. • Voltage supply fluctuation must not exceed ± 10% of rated voltage. Electricity supply lines must be independent of welding transformer which can cause high supply fluctuations.
MCM-D MCM061C Figure B Please ensure that the following steps are taken : • Check the gradient for drainage flow as recommended in Figure B. • Provide clearance for easy servicing and optimal air flow as shown in Figure C. • The indoor unit must be installed such that there is no short circuit of the cool discharge air with the warm return air. • Do not install the indoor unit where there is direct sunlight shining on the unit. The location should be suitable for piping and drainage installation.
MCM061/ 062C Figure C • Provide the installation space as shown in Figure D.
Installation - Ceiling Exposed Type STEP 1 Remove air intake grille, side panel, side close-up and hanger bracket from the unit; see Fig E. SIDE CLOSE UP HANGER BRACKET SIDE FRAME AIR INTAKE GRILLE Figure E STEP 2 Position the hanger rods as per Fig B and install the hanger bracket; see Fig F. Figure F STEP 3 Hanger up the unit and tighten the bolt, after completed the piping and drain pipe; install back the grille and panel Fig. G.
Installation - Floor Standing Type (OPTIONAL SPECIFICATION) STEP 1 Remove air intake grille, side panel, side close-up and side panel from the unit; see Fig E. STEP 2 Position the floor support (field supply) as per Fig B. install the unit; see Fig I. Wall Wall Fig I STEP 3 Two types of piping and drain pipe connection as Fig J.
(2) Installation of Outdoor Unit As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve maximum cooling capacity, the location selected for outdoor unit should fulfill the following requirements: • Install the condensing (outdoor) unit in away such that hot air distributed by the outdoor condensing unit cannot be drawn in again (as in the case of short circuit of hot discharge air). Allow sufficient space for maintenance around the unit.
(3) Refrigerant Piping Maximum Pipe Length And Maximum Number Of Bends • When the pipe length becomes too long, both the capacity and reliability drop. As the number of bends increases, system piping resistance to the refrigerant flow increases, thus lowering the cooling capacity, and as the result the font compressor may become defective. Always choose the shortest path and follow the recommendation as tabulated below: MODEL DATA Max. Length, L Max. Elevation, H Max. No.
(5) Vacuuming and charging • The precharged outdoor unit does not need any vacuuming or charging. However once it is connected, the connecting pipe line and the indoor need to be vacuumed before releasing the R22/R407C from the outdoor unit. 1) Open the service port core cap. 2) Connect pressure gauge to the service port. 3) Connect the line to vacuum pump. Open the charging manifold valve and turn the pump on. Vacuum to –0.1 MPa (-760mmHg) or lower.
(6) 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).
(8) Standard Operating Condition Cooling Only Unit Temperature minimum indoor temperature maximum indoor temperature minimum outdoor temperature maximum- outdoor temperature Ts °C 19.4 26.7 19.4 46.0 Th °C 13.9 19.4 13.9 24.0 Ts °C 15.0 26.7 -8.0 24 Th °C -9.

Trouble Shooting 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.
The design of the MLC 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.

For Cooling Only Models Or Heat Pump Models (Cooling Cycle) 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.

For Heat Pump Models By means of pressure readings : Too High PROBABLE CAUSE A Little High Circuit Normal Too Low Data A Little Low PRESSURE High Side Low Side 1. Overcharged with refrigerant. 2. Non-condensable gases in refrigerant circuit (e.g. oil). 3. Obstructed air-intake/discharge. 4. Short circuiting of hot air at outdoor unit. 1. Poor compression/no compression (compressor defective.) 2. Check valve stick in open position. 3. Reversing valve leaking. 1. Undercharged with refrigerant. 2.
The most common causes of air conditioner failure to “start" are: a) Voltage not within ±10% of rated voltage. b) Power supply interrupted. c) Control settings improper. d) Air conditioner is disconnected from main power source. e) Fuse blown or circuit breaker off. ii) Diagnosis of Refrigerant Circuit / Application There might be some cases where the unit starts running but does not perform satisfactory, i.e. insufficient cooling.
