8. Detailed Construction Sequence (Methodology)

Necessary approvals prior to installation:

a. All material used shall be approved prior to installation b. All materials and documentation relevant to a particular section of works will be checked by the site/project engineer prior to the commencement of work ensuring that these are of the correct type as reviewed by the client. c. Before commencement any construction works, pre-inspections will be carried out on all materials prior to them leaving the storage area i.e. quantity, physical damage and brand/make. d. Works shall not proceed until an approved shop drawing or detail is issued. e. Safe Access to work areas shall be provided and shall be approved by the competent safety person prior to commencement of works if applicable. f. Store the materials properly and prevent the damage to material while loading & unloading.

8.1. Procedure

PRE INSTALLATION ACTIVITIES  Be sure that all installation works are complying with the approved schematic, Shop drawing, Data point schedule and Method statement approved by the Consultants/Clients.  Ensure the location where the panel were installed is acceptable.  Make sure the location selected is dry and free from electrical interference.  Ensure that there is access to the equipment/unit so technicians can easily terminate the cables, Replacing the faulty controllers & Monitoring LED’s during operation.

 Mount the thermostat in a clean and dry location away from the window, air ducts and other places where environmental factor may affect temperature & Humidity reading.  Mount not more than 48” from floor and with a minimum clear floor space of 30”X 48” to be operated by handicaps easily.

INSTALLATION ACTIVITIES

Electrical Wiring & Connection Installation

a) Install raceways, boxes, and cabinets. b) Install building wire and cable c) Install signal and communication cable  Conceal cable, except in mechanical rooms and areas where other conduit and piping are exposed.  Install exposed cable in raceway.  Install concealed cable in raceway.  Bundle and harness multi-conductor instrument cable in place of single cables where several cables follow a common path.  Fasten flexible conductors, bridging cabinets and doors, along hinge side; protect against abrasion. Tie and support conductors.  Number-code or color-coded conductors for future identification and service of control system, except local individual room control cables.  Install wire and cable with sufficient slack and flexible connections to allow for vibration of piping and equipment. d) Connect manual-reset limit controls independent of manual-control switch positions. Automatic duct heater resets may be connected in interlock circuit of power controllers. e) Connect hand-off-auto selector switches to override automatic interlock controls when switch is in hand position.

A. BCM Modules  Use the screw behind the front cover of the module to open the tabs on the rear of the BCM.  Position the unit against the DIN rail, and then re-tighten the screw when the BCM is in position.  Strip a maximum of 3/8" (10 mm) of the wire jacket from the end of the cable.  Use a small screwdriver (1/8'' max.) to turn the adjustment screw fully counter-clockwise. The clamps in the wire slot separate as you turn the screw.  When the clamps in the wire slot are fully open, insert the stripped end of the cable (the insulation end must be flush with the terminal block). Be sure to insert all cable strands into the wire slot.  Hold the cable in place and turn the adjustment screw clockwise to tighten it until the clamps in the wire slot secure the cable.  Tug gently on the cable to ensure that it’s securely terminated. B. VLC Controllers  Each VLC consists of a circuit board with a plastic cover, which has screw holes for mounting. This should be mounted on the DDC enclosure mounting plate.  Strip a maximum of 3/8" (10 mm) of the wire jacket from the end of the cable.  Use a small screwdriver (1/8'' max.) to turn the adjustment screw fully counter-clockwise. The clamps in the wire slot separate as you turn the screw.  When the clamps in the wire slot are fully open, insert the stripped end of the cable (the insulation end must be flush with the terminal block). Be sure to insert all cable strands into the wire slot.  Hold the cable in place and turn the adjust the screw clockwise to tighten it until the clamps in the wire slot secure the cable.

 Tug gently on the cable to ensure that it’s securely terminated.  Terminate the Communication, Power & I/O cable according to above procedure.

C. Thermostat (Microset-II)  Remove the back plate from the Micro set II and the wiring pigtail.  Flip the back plate so the smooth surface faces the mounting surface.  Rethread the wires through the central knockout on the back plate.  Use the wire nuts or other connectors to splice the Micro set II wires to the wire run from the VLC.  Secure the Mounting plate with the enclosed screws.  Hold the Micro set II at an angle above the plate and then slide it down. The two tabs on the inside top edge of Micro set II should fit into the tab slot on the back plate.  Push the bottom of Micro set II onto the back plate legs until they snap securely on the tab stop.

D. Sensor & Other Field devices.  Install the sensors/field devices according to the manufacturer printed instruction.  Maintain minimum working space at equipment’s according to the shop drawings.  Terminate the cable as per below procedure  Strip a maximum of 3/8" (10 mm) of the wire jacket from the end of the cable.  Use a small screwdriver (1/8'' max.) to turn the adjustment screw fully counter-clockwise. The clamps in the wire slot separate as you turn the screw.  When the clamps in the wire slot are fully open, insert the stripped end of the cable (the insulation end must be flush with the terminal block). Be sure to insert all cable strands into the wire slot.  Hold the cable in place and turn the adjustment screw clockwise to tighten it until the clamps in the wire slot secure the cable.  Tug gently on the cable to ensure that it’s securely terminated

Miscellaneous Installation Requirements a) All wiring and tubing shall be supported and run in neat and workmanlike manner.
