INSTALLATION PREP

DETERMINE LOCATION: It is best to determine the location of the junction box during the system design process to ensure proper installation and code compliance. Note the following requirements to determine the proper location.
CAUTION

LOCATION REQUIREMENTS:

• JUNCTION BOX MUST BE INSTALLED BETWEEN RAFTERS. DO NOT INSTALLJUNCTION BOX DIRECTLY OVER RAFTER,
• THE SEALING AREA OF THE JUNCTION BOX MUST BE INSTALLED ON A FLAT, COPLANAR SURFACE. DO NOT INSTALL THE JUNCTION BOX SEALING AREA DIRECTLY ON TOP OF SEAM, VERTICALJOINT OR ON TWO SHINGLE COURSES OR LAYERS. SEE BELOW.
• PRIOR TO DRILLING INTO THE ATTIC ENSURE NO ELECTRICAL WIRES, CIRCUITS OR COMPONENTS ARE ON THE OTHER SIDE.

WARNING!

IF INSTALLING JUNCTION BOX UNDERNEATH MODULES, ENSURE THE SYSTEM GROUND PATH WILL NOT BE DISTURBED OR BROKEN DURING SERVICING. FAILURE TO DO SO COULD RESULT IN SERIOUS INJURY, DEATH OR PROPERTY DAMAGE.

1. MARK HORIZONTAL LINES:
   Mark drill hole location(s) by using jig located on deflector. Alternatively, drilling the hole in the bottom of the box and marking the location may be used.

2. MARK VERTICAL LINES:
   Mark drill hole location(s) by using jig located on deflector. Alternatively, drilling the hole in the bottom of the box and marking the location may be used.

3. DRILL HOLES:
   Drill hole(s) as needed using preferred bit.
   DO NOT EXCEED 1-7 /8″ DRILL BIT WHEN DRILLING THROUGH THE ROOF.

4. CLEAN ROOF SURFACE:
   Properly clean roof surface. ROOF SURFACE MUST BE FREE OF DEBRIS, FROST, ICE AND SNOW. Refer to Addendum B for installing in temperatures below 40 degrees F.

5. DRILL CONDUIT HOLES:
   Drill conduit holes as required in bottom and side of box. MAKE SURE TO USE DRILL POINTS INTEGRATED INTO SIDES AND BOTTOM OF BOX.

6. INSTALL CONDUIT HUB:
   Attached conduit fittings, as necessary. DO NOT EXCEED 1″ CONDUIT FITTINGS. CONDUIT FITTINGS MUST BE UL APPROVED AND RATED FOR OUTDOOR USE.

7. LIFT SHINGLE AND APPLY SEALANT:
   Directly above junction box locations lift upper course of shingles and place a thick horizontal bead of sealant. This will help adhere shingle back to the lower course. IMPORTANT: FOR 3-TAB SHINGLES ADD A VERTICAL BEAD OF SEALANT TO THE KEYWAY ON THE UPPER COURSE OF SHINGLES UPSLOPE OF BOX.

8. PLACE DEFLECTOR UNDER SHINGLE:
   Lift upper course of shingle and slide deflector under, align conduit fitting(s) with drilled holes and locate junction box.

9. SECURE TO ROOF:
   Screw all four (4) #12 fasteners through the mounting holes and into roof surface (until the washer is seated on the hole surface or until the box is fully seated). IMPORTANT: MAKE SURE TO TIGHTLY SECURE JUNCTION BOX TO ROOF SURFACE TO ELIMINATE ANY POTENTIAL BLOW OUT OF SEALANT.

10. INJECT SEALANT:
    Place one hand on top of junction box applying a sealant into the port on the upper right-hand side to 50 in-lbs).
    the of the box. Continue until the sealant vents out the left-hand side of the box through the vent.

11. ENSURE SEAL:
    Verify sealant has properly vented out left-hand side of box to ensure a proper seal.

12. CLOSE LID:
    Close lid and screw bolt into bottom of box until the TOP AND BOTTOM TABS ARE SECURED AND FLUSH

UNIRAC APPROVED SEALANTS: ChemLink DuraLink 50, ChemLink DuraLink 35 or ChemLink M1.
NOTE: Follow sealant manufacturer’s instructions. Follow sealant manufacturer’s cold weather application guidelines, if applicable.

J-Box Optional Bracket to Rail Attachment

Optionally the J-Box may be mounted directly to a solar rail via the Unirac J-Box Bracket. The dual-purpose Deflector/-Box Mount can be flipped for mounting to the -Box Bracket or used as a “Deflector” when slid underneath a course of shingle. NOTE: When mounting on north side of rail, seal existing weep holes with approved sealant and drill new weep holes using a 4mm or 5/52″ drill bit on the bottom of the box in the corners nearest to the deflector. Place weep holes at the lowest point to direct any moisture to exit the J-Box.

SOLOBOX-D Version and Din Rail Mounting SOLOBOX-D Version and Din Rail Mounting DIN RAIL COMES PREASSEMBLED AS SHOWN (SOLOBOX-D only)

OPTIONAL: DIN RAIL CAN ALSO BE INSTALLED INTO A BOX IF A NON-PREASSEMBLED BOX WAS PURCHASED.
Din rail should be cut and positioned as shown in the image above with two (2)

10 screws. If installing your own din rail, using standard 35mm x 7mm din

rail GROUNDING DEVICES SUCH AS LUGS OR GROUNDING BLOCKS. ENSURE THAT TERMINAL BLOCKS NEVER CONTACT CONDUIT HUBS.

TECHNICAL BULLETIN

DATE: JAN 23, 2014
DOCUMENT NO: CLTB 00122
TO: Contractors, Distributors, Architects & Homeowners
FROM: CHEM LINK Technical Services Division 1-800-826-1681
SUBJECT: Cold Environment Installation Guidelines

INSTALLATION AT TEMPERATURES BELOW 40 DEGREES F (4 DEGREES C) CAN BE DONE WHEN THE FOLLOWING PROCEDURES ARE FOLLOWED BY THE INSTALLER. AT THESE TEMPERATURES FROST AND ICE BECOME THE BIGGEST CONCERN AND HAVE TO BE ADDRESSED. IT IS THE INSTALLER’S RESPONSIBILITY TO ASSURE A CLEAN, FROST AND ICE FREE SUBSTRATE. THIS CAN BE ACCOMPLISHED BY USING IPA (ISOPROPYL ALCOHOL) TO REMOVE FROST OR ICE. A 90% IPA IS THE MOST RECOMMENDED, DUE TO HAVING LOWER WATER CONTENT. APPLY THE IPA IN ONE MOTION WITH A RAG, LET IT SIT FOR A MINUTE, THEN WIPE OFF IN THE OPPOSITE DIRECTION IT WAS APPLIED. DO NOT USE A CIRCLE MOTION. TO TEST FOR ICE AFTER THE IPA CLEANING SIMPLY USE YOUR HAND PRESSED ONTO SUBSTRATE, IF WATER IS LEFT BEHIND AFTER LIFTING IT, IT WILL NEED TO BE CLEANED AGAIN. ONCE THE SUBSTRATE IS CLEAN OF FROST AND ICE THE ADHESIVE OR SEALANT CAN BE APPLIED. NOTE IF THE SUBSTRATE CAN BE HEATED PRIOR TO INSTALLATION, THIS WILL ALSO ENSURE FROST AND ICE IS REMOVED.
CURE TIMES AT LOWER TEMPERATURES WILL BE DELAYED THE LOWER THE TEMPERATURE GETS. IT CAN TAKE SEVERAL DAYS FOR THE PRODUCT TO CURE (DEPENDING ON HUMIDITY AND TEMPERATURE). EXTRUSION RATE AT LOWER TEMPERATURES CAN BE AFFECTED, OUR PRODUCT DOES NOT FREEZE, BUT CAN BE HARDER TO EXTRUDE. THIS PROBLEM CAN BE RESOLVED BY WARMING THE PRODUCT BEFORE INSTALLATION FOR EASE OF USE.
CLEANERS TO AVOID INCLUDE MEK, TOLUENE, XYLENE, MINERAL SPIRITS AND ANY OTHER PETROLEUM BASED CLEANERS. THESE CLEANERS WILL PROHIBIT OUR PRODUCT FROM BONDING TO THE SUBSTRATE IN COLD OR NORMAL ENVIRONMENTS.
OPTIMAL TEMPERATURE OF 40F (4C) TO 80F (27C) IS WHERE MOST ASTM TESTING IS DONE. IF THE GUIDELINES ABOVE ARE FOLLOWED OUR HIGH PERFORMANCE MOISTURE CURING POLY ETHER ADHESIVES AND SEALANTS CAN BE APPLIED IN MOST COLD ENVIRONMENTS.
FOR MORE INFORMATION ON APPLICATION GUIDELINES, PLEASE REFER TO ASTM C1193 STANDARD FOR USE OF JOINT SEALANTS AND ADHESIVES.
