LSO Systems manufactures very high quality components built to satisfy the design professional. They are precisely crafted for a very clean attractive finished design detail. Our components are built to be easy to handle during installation and will withstand casual bumps and impacts, but are not to be dropped, stepped on, or impacted heavily during installation. Rough handling and poor installation will negatively effect the finished design.
1) Thoroughly Inspect your product packaging at the time of delivery. Report any packaging damage to us immediately. If the packaging is not damaged, we need to assume that any damage visible on the product is due to improper handling on site.
2) Minor perforated mounting flange or insulation damage is generally easily repairable on site as part of installation.
3) Minor supply edge (the visible finished opening) or secondary duct attachment fixture (the 2” round attachment) damage may be field repairable unless the field repair disrupts the visible design finish or the attachment fixture may create air flow noise.
4) Any LSO Design Component that suffers severe damage that twists or bends the housing must be replaced. Do not use any LSO Design Component that suffers more than cosmetic damage.
5) Good Installation preparation and precise layout is absolutely necessary for excellent results. We recommend the use of a laser to set framing and the LSO Design Components positions. Other methods of set up are more likely to produce variable results.
6) Be sure to consider irregular lines in the site construction to avoid visual discrepancies not related to the accuracy of the LSO Design Components.
7) Our components are more accurate than wood or metal framing. We provide generous mounting flanges to allow you to precisely align components for the design you wish to achieve.
8) The perforated mounting flanges are provided so that you can insure that they are solidly attached to the supportive framing and sheetrock. They must be securely and accurately attached for excellent results.
9) The perforated mounting flanges allow face attachment through the flange to metal or wood framing with the correct fasteners.
10) The perforated mounting flanges allow secondary, and in properly conceived and prepared installations, primary attachment of the LSO Design Components through the wall or ceiling surface to securely attach the mounting flange to the rear of this sheetrock surface. Do not over tighten these fasteners and crush the sheetrock or damage the mounting flange. Solid and secure is what is required.
11) If you only have framing attachment on one side of the mounting flanges you must provide secondary fastening through the sheetrock surface to the other side of the product. Do not over tighten these fasteners and crush the sheetrock or damage the mounting flange. Solid and secure is what is required.
12) LSO Design Components are meant to be finished to the edge of the opening. The tapers knife is guided along this edge. All that should be visible is the opening.
13) If conditions on site, or over time and settling of the construction, create hairline separations between the surface finish and the housing edge, they are considered part of the normal touch up and finish work necessary on site and this is generally handled on a regular basis by painters caulk or other method.
14) If the sheet rock installers leave, or in the case of LSO Ceiling Design Components (on one side due to the angle of the air path), a gap between the finished surface and housing edge more than 1/4”, the tape and joint work should include filling these gaps with a product like Durabond or other cement like filling prior to applying the base and finish coats of joint compound.
15) Our housings are aluminum. During installation and final finish preparation the installer may be create slight scratches in the very tough powder coat finish of the housing. These can touched up or will be covered with your final finish reliably.
16) IMPORTANT NOTE: AIRFLOW NOISE AND REDUCED SYSTEM PERFORMANCE IS GENERALLY CREATED IN THE SECONDARY DUCT DESIGN AND INSTALLATION. THIS IS COMMON TO ALL TYPES OF FORCED AIR SYSTEMS WHETHER THEY ARE CONVENTIONALLY DUCTED SYSTEMS (WITH SUPPLY GRILLES OR REGISTERS) OR SMALL DUCT SYSTEMS (WITH COMMONLY ROUND OR SLOTTED SUPPLY OUTLETS). THE NOISE YOU MAY HEAR IS THE RESULT OF TURBULENCE CREATED WITHIN THE SECONDARY DUCT OR AT THE ATTACHMENT POINT TO THE SUPPLY GRILL, REGISTER, OR OUTLET ATTACHED TO INTERIOR FINISHED SURFACE. POOR PRIMARY DUCT SYSTEM DESIGN AND INSTALLATION IS USUALLY EVIDENCED BY POOR SYSTEM PERFORMANCE.
17) TO PREVENT UNNECESSARY AIR FLOW NOISE AND REDUCED SYSTEM PERFORMANCE, READ THE FOLLOWING NOTES RELATIVE TO SECONDARY DUCT DESIGN AND INSTALLATION SUPPLIED BY AN HVAC CONTRACTOR ON YOUR PROJECT- A) SECONDARY DUCT ATTACHMENTS TO LSO DESIGN COMPONENTS SHOULD HAVE A STRAIGHT OR VERY GENTLY CURVED APPROACH IN LINE WITH THE ATTACHMENT FIXTURE/CONNECTION THAT IS NO LESS THAN 15” LONG (FROM THE ATTACHMENT FIXTURE/CONNECTION POINT). THIS SECONDARY DUCT APPROACH SHOULD BE SUPPORTED TO AVOID THE DUCT “HANGING” ON THE ATTACHMENT FIXTURE AND OVER TIME SAGGING AT THIS CONNECTION TO CREATE TURBULENCE AND NOISE. B) IF THIS DIMENSION CAN BE LONGER, HIGHER AIR VOLUMES AND VELOCITIES THAN NORMAL (IN SOME LSO DESIGN COMPONENTS) CAN BE ACHIEVED. IF IT IS SHORTER, TURBULENCE NOISE OR REDUCED SYSTEM PERFORMANCE MAY OCCUR DEPENDING ON THE REDUCTION IN THIS DIMENSION. C) DO NOT SEVERELY CRAMP, CRUSH OR TURN THE SECONDARY DUCT PATH AT ANY POINT IN ITS LENGTH. NEVER CRAMP, CRUSH, OR TURN THE SECONDARY DUCT AT THE LSO DESIGN COMPONENT FIXTURE/CONNECTION POINT UNDER ANY CIRCUMSTANCES. CRAMPING, CRUSHING OR TURNING THE SECONDARY DUCT AT THIS POINT WILL CREATE TURBULENCE NOISE AND RESULT IN LOWERED PERFORMANCE. ATTEMPT TO ALLOW A STRAIGHT OR VERY GENTLY CURVED PATH TO THE LSO DESIGN COMPONENT FIXTURE/CONNECTION POINT AT LEAST 15” LONG. OPTIMIZE THE SECONDARY DUCT PATH FOR EXCELLENT AIR FLOW.
