InstallationReceivingAll units leaving the McQuay plant have been inspected to ensure the shipment of high quality products andreasonable means are utilized to properly pack the fan coil units to protect them in transit.Carefully inspect all shipments immediately upon delivery. When damage is visible, note this fact on thecarrier’s freight bill and request that the carrier sends a representative to inspect the damage. This may bedone by telephone or in person, but should always be confirmed in writing.The shipment should be unpacked in the presence of the agent so that the damage or loss can bedetermined.The carrier’s agent will make an inspection report and a copy will be given to the consignee for forwardingto the carrier with a formal claim.LocationBefore installation, please check the following:There must be enough space for unit installation and maintenance. Please refer to the unit’s drawings anddimensions and fig.1 for the minimum distance between the unit and obstacle.Please ensure enough space for piping connection and electrical wiring.Please make sure that the hanging rods can support weight of the unit.InstallationThe unit is designed for concealed ceiling installation.There are holes on the top of the unit for hanging. Please refer to Fig.1.Fig.2 and Fig.3.Make sure that the top of the unit is level.Insulation1)2)3)4)Use proper insulation material onlyChilled water pipes and all parts on the pipes should be insulatedIt is also necessary to insulated air ductedAdhesive for insulation should work under range 0 F(-18 C) to 200 F(93.3 C).Fig.1OBSTACLEBACEILINGA 200mmB 400mm13C 265mmCOBSTACLE

Refer to the specificationThe water inlet is on the bottom while outlet on top.The connection must be concealed with rubberized fabric to avoid leakage.Drainpipe can be PVC or steel.The suggested slope of the drainpipe is at least 1:50.Wiring1) Wiring connection must be done according to the wiring diagram on the unit.2)3)4)5)The unit must be GROUNDED well.An appropriate strain relief device must be used to attach the power wires to the terminal box.A 7/8” knockout hole is designed on the terminal box for field installation of the strain relief device.Field wiring must be complied with the national security regulations.14
Valve KitThe valve kit is applied for 2-pipe system.The kit consists of (refer structure figure 0): 2/3 way valve body is made of brass, maximum working pressure 1.6MPa. Electric actuator has the following specifications:-Power supply: 220V 10%/50/60Hz ( 2Hz)-Activation: ON/OFF Hydraulic kit for the installation of the valve on the heat exchanger, complete with 2 ball valves foradjusting the water flow and for closing the water circuit when perform maintenance to the unit. Y-strainer protects unit from impurity, increases the service life and insolating valves.Figure 0All parts of 2-way valve kit are indicated in the figure 1.

Installation1. Install the 2-way valve kit as indicated in the pictures of figure 3. (For right pipe connection unit.) Asshown as detail A, firstly take apart connector, then install ① to unit with necessary sealing material . Fix② between ① and ③. At last tighten ③, make sure all of connectors are sealed.2. Install the 3-way valve kit as indicated in the pictures of figure 4. (For right pipe connection unit.) Detail isas same as 2-way valve unit.The valve kit has been pre-assembled for easy installation. Where needed the connections are pre-coated with sealing material. The connections are not tightened for easy adjustment. After determining the final position of the valve kit, tighten all connections to obtain water tightness.WATER RETURN CONNECTION Rc3/4WATER SUPPLY CONNECTION Rc3/4209Ĺ22020365ķAĸ146Detail AFigure 32-Way Valve218153300ĹķĸDetail AWATER RETURN CONNECTION Rc3/4WATER SUPPLY CONNECTION Rc3/4120210A16
Insulation1. The insulation design and materials should be complying with local and national codes and regulations.2. Chilled water pipes and all parts on the pipes should be insulated.The flow resistance of the connecting valve/hydraulic kit assembly is obtained from the following formula: PW (QW/100Kv)2PW is the flow resistance (Pa)QW is the water flow rate (m3/h)Kv is the flow rate identified in the tableValve ModelDNConncetionTypeValve TypeKVShut-off PressureDifference (MPa)MC-FCV3335G20Rc3/4"3-way Valve3.40.18MC-FCV2334G20Rc3/4"2-way Valve3.00.18Pipe Connection1.2.3.4.Using suitable fittings as water pipe connections with reference to the outline and dimensions.The water inlet is on the bottom while outlet on top.The connection must be concealed with rubberized fabric to avoid leakage.Tightening torque should not be too high when connecting water pipes, in order to avoid brass deformationor water-leakage by torsion split.Wiring1. Refer to the wiring diagram of the appropriate controller.2. For connection with the McQuay controller, position the water temperature probe into the appropriateposition.
