ii) Fan mode is not available in valveless control.

iii) Wired handset (Netware and SLM) has an indoor room sensor. Avoid locating the wired handset at isolated places where room temperature reading will be inaccurate.

Water Piping Connection

The indoor unit is equipped with water outlet and inlet bare connection. There is an air-vent for air purging that is fitted at the outlet water header.

3 ways solenoid valve is required for cycling off or bypass the chilled water.

Black steel pipe, polyethrene pipe, PVC pipe and copper tube recommended in field installation.

All types of piping and connection must be insulated by polyurethane (ARMAFLEX type or equivalent) to avoid condensation.

Do not use contaminated or damaged pipe and fitting for installation.

Some main fitting components are needed in the system to enhance the capacity and ease of service, such as gate valve, balancing valve, 2 ways or 3 ways solenoid valve, filter, strainer etc.

Preliminary Site Survey

Electrical supply and installation is to conform to LOCAL AUTHORITY's (e.g. National Electricity Board) CODES and REGULATIONS.

Voltage supply fluctuation must not exceed ± 10% of rated voltage. Electricity supply lines must be independent of welding transformers which can cause supply fluctuation.

Ensure that the location is convenient for wiring and piping.

Mounting

For ceiling mounted models, locate a position where piping and ducting work can be kept to a minimum. Ensure that overhead supports are strong enough to hold the unit's weight. Position hanger rods and check for alignment with the unit. Check that hangers are secure and that the base of fan coil unit is level in two horizontal positions.

Piping

Drain and water piping must be accurately connected.

Please refer to "Specification Sheet" for piping sizes.

Piping Support

All water mains must be adequately supported to carry the necessary weight involved, provisions must be made by the installing contractor to allow for adequate free movement of all vertical and horizontal risers and run outs. Due to the fact that cold water will be circulated through the water mains, a sizeable movement of the water mains can be expected due to contraction. If for example, the piping is rigidly supported with no provision for movement, it is very possible that the tubing of fitting may be broken causing water leakage in the conditioned spaces throughout the building.

Coil Venting

Each standard basic unit coil is equipped with a manually operated air vent which is installed at the end of a small copper line leading into the highest point of the coil. By means of this valve, air may be vented manually, from the coil to keep it operating at full capacity. When water is first introduced into a coil, air is sometimes trapped in the coil tubing. This trapped air will reduce cooling capacity and create "Bubbling" or "Clanking" noise within the units. To release air trapped in the coil, press the air vent head to allow air to flow out of the air vent opening. Release when a steady stream of water appear.

Electrical Connection

As wiring regulations differ from country to country, please refer to your LOCAL ELECTRICAL CODES for field wiring regulations and ensure that they are complied with. Besides, take note of the following general precaution:

1) Ensure that the rated voltage of the unit corresponds to the name plate before commencing wiring work.

2) Provide a power outlet to be used exclusively for each unit and a power supply disconnect and a circuitbreaker for over-current protection should be provided in the exclusive line.

3) The unit must be EARTH to prevent possible hazards due to insulation failure.

4) All wiring must be firmly connected.

General Operation Guide

Start-Up

The following procedure must be completed before any attempts is made to put the entire system Into operation:

1) Piping connections completed.

2) Electrical connections completed.

3) Duct connections completed.

4) Auxiliary drain pans in position where required.

5) Drain line draining into drain pans.

6) Filters correctly installed and free of construction debris.

7) Motor-blower assembly rotates freely.

8) Unit Hydro-statically tested and air vented.

Starting The Fan Coil Unit

1) Turn on the switch of water pump.

2) Start water chiller.

3) Operate the fan coil unit by turning on the fan and set the control switch to get the desired speed.

4) Inspect the duct and piping condition and rectify problem (e.g. vibration, noise, etc.) if exist.

Servicing And Maintenance

Fan coil units are designed to operate continuously with minor routine maintenance. Since fan coil units cool the discharging forced air, the efficiency with which the units operate is directly related to the amount of air passing through the coil.

Air Filters

The function of the air filters is to remove foreign matter such as dirt, soot, pollen and certain other impurities from the air passing through it. A clogged or dirty filter not only fails to do the job for which it is designed, but restricts the flow of air over the coil.

The importance of cleaning the filter before it becomes clogged must be greatly stressed. The frequency with which a filter should be cleaned will depend upon the amount of dust and foreign material that enters a unit, and this depends upon location and situation.

The washable viledon or saranet filter may be cleaned by tapping the filter on a solid surface to dislodge heavy particles. Wash under stream of warm water, with detergent if necessary. Dry it thoroughly before replacing.

Fan Motor

The fan motor is pre-lubricated and sealed at the factory. Therefore, no lubricating maintenance is required.

Coils

Clean coil unit by brushing between fins with a nylon brush. Brushing should be followed by cleaning with a vacuum cleaner. The coil may also be cleaned by using a high pressure air hose and nozzle if a compressed air source is available. It should be pointed out that if suitable air filter is used and taken care of properly, the coils need no cleaning.

Drain Pipe

The drain pipe should be checked before operation of unit is begun. If it is clogged, steps should be taken to clean the debris so that condensate will flow out easily.

Replacement Of Parts

Replacement of parts are available through your local dealers. When ordering parts, you must supply

1) Model name of the unit.

2) Serial number of the unit.

3) Part name and number.
