2.6 Points for Attention during Installation
For ceiling installation, hang the unit on threaded rods using the mounting holes provided. Alternately rubber
isolators or spring mounts can be used. YECFC units exhibit low levels of unit vibration and have high levels of
balance as each direct drive EC fan / motor assembly is provided as a single manufactured and tested entity from
the supplier.
Ensure correct spacing and alignment of mounting points directly above the mounting points on the unit chassis.
This is important where the suspension points have been fixed into the concrete slab directly above the unit.
During the installation, be careful to avoid building materials damaging unit panels or components.
Do not remove protective covers from the coil connections until the unit is ready to be piped up.
Before the unit starts operation, any debris in the drain tray and the drain piping should be removed.
Ensure sufficient side clearance to enable air filter removal. Allow at least 600mm service clearance.
Installation of CB series-ceiling concealed type unit: Insert the reserved screws on ceiling to the six kidney-shaped
holes.
2.7 Installation
2.7.1 Water Piping
Flow and return water pipes IN and OUT are marked on the unit and water pipework should be connected through
flexible couplings to avoid transmission of vibration and to allow for pipework expansion and contraction.
YECFC water connections incorporate male pipe threads as scheduled in the table in this manual.
Do not overtighten the water connections. Torque should not exceed 50 N.M so as to avoid breakage. Significant
care should be taken when attaching water pipes or water valves to the coil connections.
In order to confirm the unit is not damaged during transportation, leakage inspection (1.0Mpa) for coil is required
before installation.
Use a pipe wrench to restrain the pipe connections of the coil when connecting external pipework.
2.7.2 Piping Support
The weight of all connecting water pipes should be independently suspended and should not be borne by the unit.
Provide a minimum of 600mm service access to all water inlet, outlet and drain pipe interfaces.
2.7.3 Determination of Water Handing of the Unit
The water inlet and outlet pipe interfaces can be arranged in the right or left side of the unit. When viewing from
the unit air outlet (or reverse the air flow direction), if the water inlet and outlet pipes are at the right side of the
unit, the unit is called a Right-handed Unit; conversely, it is a Left-handed Unit.
Ensure correct handing of the unit to be installed.
2.7.4 Condensed Water Drainage
Install the YECFC fan coil level using a spirit level. Adjust the hanger rods or mounting bolt tension to achieve
minimum 5 mm side to side slope towards the drain outlet pipe. Do not install the unit with a slope away from the
drain outlet pipe.
The external drain piping should slope downward and away from the fan coil unit.
Note: YECFC units are a “blow through” design.
2.7.5 Water Treatment
Chilled and hot water systems must be filled with clean and properly treated water.
Water circuits must be adequately flushed to remove construction debris.
