GLAZING GUIDELINES
RECEIVING
Before signing for and accepting the shipment from the carrier, inspect the crate(s) for any visible damage.
If damage to any of the panel(s) is found, the shipping documents should be so noted and the driver’s signature obtained as a witness. You should inform us immediately of any damaged panels. Photographs or video should be sent within 24 hours. A freight claim should be filed to the carrier as early as possible.
The customer is responsible for unloading the crate/skid from the truck.
When lifting the crate the forks must be in a central position and the crate must be fully supported. Do not attempt to lift the crate unless it is evenly supported.
When the shipping or receiving location does not have a loading dock, manual loading or unloading is necessary.
Lift-gate service is not always available depending on the crate size. You must let us know in advance if you require a lift-gate delivery.
OPENING THE CRATE
Ensure the crate is on a level surface. Before removing the lid unscrew the screws that are holding the lid down. Be careful to lift the lid off the crate level on all corners. Remove straps holding panels on. Remove the panels carefully, one at a time, using the appropriate lifting methods.
Warning: Loose cables from PriWatt glass panels are not to be used for lifting, moving or positioning the glass panels. Ensure not to snag cables whilst lifting.
GLASS INSTALLATION
- Inspect each piece of PriWatt Glass immediately prior to start of installation.
- Do not install items which are improperly sized, have damaged edges, or are scratched, abraded, or deficient in any other manner.
- Do not remove labels where provided by manufacturer until so directed by Architect, client or site manager.
- If the installer has any questions or concerns please immediately contact your smart glass technical specialist.
INTERIOR GLAZING
Smart glass panels can be butt glazed. Long edges will be polished giving an even vertical finish. Panel thickness will vary depending on several conditions including the height and span of the glazed area. We will advise minimum glass thickness for manufacturing considerations but it is for the client to ensure that glass thickness is suitable for purpose and complies with all local building codes.
SETTING BLOCKS
In figure 1, you can find a drawing that summarizes the correct usage and placement of setting blocks including points such as:
- Setting blocks are placed at a quarter point of the glass
- Minimum length of the setting blocks is 100mm
- Minimum distance is 150mm from glass corner
It is very important to make sure that once the glass is placed on the setting blocks, the setting blocks are well positioned and will not be able to shift outward\inward in the frame. This will prevent the glass from partially resting on the setting blocks.
GLAZING METHODS
- Wet Glazing: Never use putty or glazing compound to glaze PriWatt Glass. Edges of PriWatt glass panel are to be protected using Flowstrip edge tape. Only use non-acetic sealants, (DOWSIL 737 Neutral Cure Sealant Clear/Black/White), supplied by manufacturer.
- Butt-Joint Glazing: PriWatt glass panels can be butt-joint glazed in interior applications (Long edges polished recommended). The joint can be silicone (only use silicone supplied by Smart Glass Group) or dry joint as required.
- Exterior Applications: Insulated Glass Units made with PriWatt glass can be installed as per normal glazing with the exception of accommodating the unit wiring. The PriWatt glass panel must be fitted as the interior panel. Smartglass is suitable for glazing to steel, timber, aluminium and UPVC framing systems.
SILICONE
IMPORTANT!!! USE ONLY NEUTRAL CURE SILICONES. DO NOT USE ACETIC SILICONES!!!
- Smart Glass Technologies only recommends DOWSIL 1199 Neutral Cure Sealant Clear/Black/White as the sealant for use in butt-joint glazed PriWatt glass panel systems. Use of any other type of silicone sealant will void the warranty.
- Structural Silicone Glazing: Insulated glass units manufactured with PriWatt glass should not be structurally silicone glazed unless agreed in advance & in writing by the PriWatt glass manufacturer.
ELECTRICAL GUIDELINES
Electrical installation of PriWatt™ Glass requires the following items:
- A 15 AMP ground fault interrupter circuit breaker with 110VAC 50-60Hz (installer/owner supplied) electricity.
- A wall mounted switch, 110VAC 50-60Hz (electrician or owner supplied). This switch is required to allow the panels to be turned ON/OFF. Smart Glass Manufacturer recommendation is LUTRON CASETA.
- Power transformer 48VAC (supplied).
- Transformers contain 2A Fuse within the housing (supplied).
In a standard case scenario each PriWatt Glass panel has two busbars. Busbars can be located as follows:
- If your panel has a different busbar setup, please call your Smart Glass consultant prior to commencing the installation.
- Each busbar has two wire leads. One busbar has 2 RED wire leads, another busbars has 2 BLACK wire leads.
- One of the wire leads is SPARE in case of any damage during the transportation or installation process. Please shrinkwrap it and conceal it safely in the frame.
- You have to connect one of the RED wires to one polarity of the Transformer Output (48-56 Volts) and one of the BLACK wires to the other polarity of the Transformer Output (48-56 Volts).
The PriWatt glass panels can be connected in Daisy chain or Parallel:
Electricical installation notes:
- Before installation commences, busbars, connection leads, and cables should be inspected to ensure the integrity of the insulation.
- DO NOT ATTEMPT TO INSTALL THE PriWatt™ GLASS PANELS ON A LIVE CIRCUIT.
- PriWatt™ Glass operates at 48VAC, if the local main voltage is higher than 110VAC, a step-down transformer is required.
- Smart Glass Group, manufactures and supplies a range of thermally protected UL & CSA Certified isolating transformers. Failure to use PriWatt™ Transformers may result in irreparable damage to the PriWatt Glass.
- It is important not to exceed the maximum square feet area power limit of the provided transformers.
- Install only on a GROUNDED 110VAC circuit protected by 15A fuse or breaker. The circuit must also be protected by a ground fault circuit interrupter.
- Do not connect any other devices or products to the output of the PriWatt™ transformer.
- The transformer must be installed by the electrical contractor in an easily accessible and well ventilated area. They must be installed into a suitable enclosure supplied by others.
- PriWatt™ Glass is an electrical component and should be provided for the electrical layout, including the provision of fused spurs, switches, cable management, and electrical connection boxes.
- All installations must meet the requirements of local regulations and guidelines and be carried out by a qualified electrician.
- Any metal framework close to or adjoining the wiring of the panel MUST be earthed.
- Always use a grommet when drilling holes in frames or channels to protect the cables from potential damage.
- Great care should be taken to ensure that exposed busbars, leads, or cables do not come into contact with the framework, and any metal frames must be earthed and sealed to prevent the ingress of moisture or water.
- When connecting the power supply, please ensure that the device will not give unwanted tripping due to high inrush currents generated by the transformer(s).
- The manual switch or remote control must be wired into the circuit on the main voltage side of the transformer. Failure to observe this requirement may lead to irreparable damage to the PriWatt™ Glass panels.
- Before turning on the power to a new installation, the electrician should test the resistance reading between the frame and the busbar feed cables to ensure that the reading resistance is infinite. If this is not the case, the short circuit should be found and insulated accordingly.
FUSE REPLACEMENT
OPERABLE WINDOWS & DOORS
There are several options for using PriWatt glass in doors including top and bottom rails and conventional patch fittings. Please contact us for further information.
Door handle detail
Back to Back pull handles are used as standard on PriWatt doors. Ensure the pull handles you are using will cover the hole in the LC Film, this is generally 7/16 inch wider diameter all round than the bore hole in the glass for the pull handle fixing bolts.
Allowances will have to be made for the difference in height between the door and the panel with the receiver to ensure they line up correctly.
Cable routing detail
When using a framed door system, you have to remember that the wiring must make its way from the glass out of the door frame. We recommend that a concealed door loop is used. The cable can then be passed through the stile of the door – door loop – door frame and then continued on to the ceiling void and transformer.
Wiring-in PriWatt™ Glass into Hinged Doors and Opening Windows
When fitting PriWatt™ Glass panels into swinging doors or opening windows, it is desirable to fit a concealed device into the frame to accommodate the required flexibility in the power cord. Which device you would require would depend on the specific nature of the frame, be it door or window. Power Transfer Units are made specifically for this purpose.
