Nomenclature

FeaturesGeneral InformationMcQuay for years has been committed to provide high quality air handling systems of various models and types, and has made remarkable achievements in the industry. As a new generation of products, the MHW series slim ceiling air handling units are launched by McQuay to adapt to the increasingly cramped building layout.In addition to the outstanding performance of previous McQuay air handing units, the MHW series slim ceiling air handling units feature a slim size, only 420mm in height. The airflow is adjustable within the range of three levels to meet different air flow needs. Powered by a 50 or 60Hz single-phase power supply, this series eliminates the need for users to expand the power capacity. The MHW series can be mounted in a wide variety of places, especially those with limited space and high noise. Featuring easy installation and flexible use, the MHW series helps minimize the indoor space and maximize customers’ benefits.

StructureThe high-strength galvanized steel sheets, coated with electrostatic spraying, are highly corrosion-proof.Made of a new type of PE material, the heat insulator features ideal thermal insulation, sound absorption, and no moisture permeability. The insulator is also proof against cold bridge.

FansWith efficient tilted multi-blade centrifugal fans, this unit provides low noise but high reliability. The fan and the motor are coupled directly. The high-precision and quality ball bearing eliminate the need for lubricating.

Multi-level Speed ControlDriven by a single-phase capacitor-running asynchronous motor, the unit can be adjusted at three levels to provide different amounts of air flow.

FiltersThe air inlet is equipped with primary nylon filters.

Heat ExchangerMade on the OAK manufacturing facility the heat exchanger uses thin-walled copper tubes mechanically expanded into new-type fins, to ensure close contact between the cooper tubes and fins. This enables the coils to provide best heat exchange and the units to run reliably and efficiently.

PerformanceMHW series products feature high external total pressure (ETP) and large cooling capacity. Slim in size and simple in structure, this series makes it easy for installation and maintenance.

InstallationImportant NoticeInstallation and maintenance are to be performed only by technicians who are familiar with local rules and regulations, and experienced with this type of equipment.Make sure that the rated voltage of the power supply conforms to the voltage stated on the unit nameplate.Cut off all power supplies before mounting or maintaining the unit.Electric connections must conform to local laws and regulations.The voltage should fluctuate within the range of ± 10% of the rated voltage.The unit must be well earthed to prevent insulation failures.All the wires must be securely connected.The design of water pipes and ducts must conform to the specifications of heating, ventilation and air conditioning norms and regulations.

Mounting LocationMake sure it’s convenient to connect wires and pipes in the selected mounting location. The minimum space reserved around MHW units is shown in Figure 1.

Figure 1

Suspending InstallationDuring suspending installation, please handle the unit or packing case with care, to avoid damage to any part. Before leaving the factory, the unit or its packing case already has forklift handling holes or hoisting holes. During the hoisting, the lifting poles should be strong enough to bear the unit weight. Please handle the MHW unit as shown in Figure 2.

StorageWhen a unit is placed outdoors before it is installed in an equipment room, please protect it from dirt, rain, snow and even animals. Be sure not to damage the protective film on its surface.

Base SetupAdjust the base level.The base, if not on a level surface, may result in water leakage or break the dynamic balance of the fan due to poor drainage of condensing water, or cause the bearing malfunction or vibrate.The base height should match the U-shaped pipe bend. The drain pipe should be connected with the U-shaped water seal, as shown in Figure 3.

Service and maintenanceNoticesResponsibilities and ObligationsThis product comes to you with the McQuay service warranty. Only McQuay technicians or experienced technicians authorized by McQuay are allowed to install, test or maintain these products.

Use the UnitAfter installing the piping system, please first flush the pipes. To do so, be sure to shut off the valve connected to the unit, to prevent contamination in the pipes from entering the coils or blocking the loop.After the installation, please check there is anything sundries inside the fan. Turn the blades by hand. If no unusual noise is heard, turn on the fan, to see if it is running properly.Before turning on the water flow, please open the exhaust valve to let the air out of the pipe till water flows from the pipe.When the unit stops running, fill the coil with water or by other means to prevent pipe corrosion.When the environment temperature falls below 0°C in the winter, drain the pipe to prevent it from freezing.Clean the coils at regular intervals, to remove the dust from the coils. Clean the scale inside the coils every 2 or 3 years. If possible, please use soft water in the coils.Check the unit filter for dust regularly; if possible, please use a pressure difference gauge. Once the resistance reaches the limit, wash or replace the filter media in time.After the unit runs for a week, please readjust the V-belt. Afterwards, check the belt every three months.

Service and MaintenanceA good maintenance schedule helps reduce operational failures.A dirty filter may worsen the performance and air flow of the unit. Thus, replace or wash the filter in time. Be sure to check the filter every month to see if it is clean enough.Wash the coils with compressed air or water. Brush the coil surface gently with a soft brush or use a vacuum cleaner to clean the dust.Do the following on a regular basis:Clean up the fans every 6 months, to keep them in good balance.Check and clean the drain pan. Check the drain pipe in case dust or sundries block the pipes. Clean the dirt in the water coils at regular intervals.

air flow is insufficient

1. Fan Blower is mounted incorrectly Contact the dealer.

2. Duct systemActual resistance exceeds the designed value. Re-design the systemDuct is poorly sealed Seal it with glueFireproof damper is shut off Turn on the fireproof damper

3. Filter Too dirty or blocked Clean or replace the filter4. Coil Too dirty or blocked Clean coils5. Air flow is short-circuited.

The air inlet and air outlet are not properly isolated. Thus, the air runs directly to the air inlet Add air separator

6. Fan inlet is blockedElbow at the air return area fan outlet are too close to the unit wallboard Move the fan

The fan outlet is blocked Remove the obstructions

7. No straight tube at the fan air outlet

A length of straight tube is mounted at the fan outlet during fan testing. Without straight tube, the fan performance might be worsened. Thus, the fan may run faster to overcome the resistance (check the fan speed)

Install straight tube

8. There are sundries inside fan system

The fan outlet is blocked Remove the obstructionsThere is an elbow tube at the fan outlet Re-design duct

The fan is functioning but the air supply is too large

1. System
