MUC-HP4 Duct Fan Coil Units
INSTALLATION AND USER MANUAL
1. INSTALLATION
Pay attention to maintain the unit properly. The turning parts inside should not
collide .Make sure there are no superfluous items into fan, motor or coil. Also make sure
that the outlet side of a drain pan keeps 3 to 5 mm lower than the opposite side at least and
water discharges well.
2. AIR DUCT CONNECTION
In order to prevent blocking of coil fins by dust use an air filter fixed on return air grille.
3. WATER CONNECTION
Fix the connections by tightening the fan coil fitting with the wrench against wrench
system. Remember that the torque should not exceed 2.5kg.m
Make sure the correct direction of water flow. The cooling/heating water shall go through
the coil from the bottom(inlet) to the top(oulet). The installation of flexible connector is
advised to restrict vibration transmitting. To control room temperature use a room sensor
connected with 3-way or 2-way valve actuator as on the diagram. Ball valves should be
installed to adjust water flow rate or stop up the flow if needed. The drain pipe shall keep
a slope to make draining water goes freely. All pipes and regulating parts shall be
installed. When connection is finished, a leak test must be applied. Normally the testing
pressure is 1.5 times more than working pressure.

4. WIRING
Make sure of the correct color when connecting wires. Make sure that the unit is grounded
properly.
CAUTION: The dashed lines are only illustrative of how the selection of each speed.
The 3-speed switch must be able to support the fan motor consumption, so in the most
cases be performed by the circuit with auxiliary relays.
5. TEST RUN
After installation ,carry out the test run before decorate the interior.
6. OPERATION
In summer time the cooling water temperature shall not be lower than 5°C, otherwise the
dew can destroy the surface of insulation and the interior will be damaged. In winter time
the heating water temperature shall not exceed 65°C. If the unit does not work for a long
period in winter time the water must be discharged from the coils if there are no any
special antifreeze components. Otherwise it will break coils.
7. MAINTENANCE
In order to keep the normal air flow rate clean the filter and the coil permanently. Pay
extra attention in case the unit has no cooling/heating effect.
