Q-VAULT 120/277V (50/60HZ) – 24V

FOR CONDUIT CONNECTION
WARNING – RISK OF SHOCK. Install power unit 5 feet (1.5 m) or more from the pool or spa and 10 feet (3.05 m) or more from a fountain. Where the power unit is installed within 10 feet (3.05 m) of a pool or spa, connect unit to GFCI protected branch circuit.

FOR POWER SUPPLY CORD CONNECTION
WARNING – RISK OF SHOCK. Installed power unit 5 feet (1.5M) or more from the pool, spa, or fountain. Where the power unit is installed (a) indoors within 10 feet (3.05) of a pool, spa, or fountain or (B) outdoors, connect power unit to a receptacle protected by a GFCI.
WARNING – RISK OF FIRE. If installation requires running wire through a building structure, special wiring methods are needed. Contact a qualified electrician.
WARNING – Outdoor Cord-connected unit shall be connected to a GFCI protected hooded flush type cover plate receptacle marked “Wet Location”.
WARNING – Do not use extension cords.
The main Secondary Wiring is intended for shallow burial – less than 6 inches (152 mm)

For Supply connections use wire rated for at least 90C.

• SUITABLE FOR INDOOR / OUTDOOR USE
• SUITABLE FOR USE WITH SUBMERSIBLE LUMINAIRES OR SUBMERSIBLE PUMPS
• SUITABLE FOR USE WITH LOW VOLTAGE LANDSCAPE LUMINAIRES / FITTINGS

CONTACT YOUR LOCAL DISTRIBUTOR OR Q-TRAN FOR Q-WIRE, Q-CLIK OR PROPER ACCESSORY KITS.

ROUGH IN WIRING

1. Excavate a 14” x 30” x 16” deep hole for the Q-VAULT direct burial housing.

2. Dig trenches for primary & secondary wiring to Q-VAULT housing location.

3. Place drain pipe at a 30 degree angle at the lowest slope of land for proper drainage. Fill bottom of pit with a minimum of 4″ of gravel.
   SEE DIAGRAM A
   Note: Increase width to 30” x 30” when stabilizing bars are used.

4. Bring all primary and secondary wiring into housing.
   A: Entry location is provided at both the bottom and side of the Junction Box located on the Q-VAULT housing.
   B: On the bottom of Junction Box there are: (4) 3/4” NPT and (2) 1/2” NPT KO’s. SEE DIAGRAM B
   C: Using the Field Drill Guide Labels provided in the installation kit you are able to drill for various fitting sizes. Only knock out openings for conduits being utilized in installation. SEE DIAGRAM C
   

5. After all field wiring has been installed with proper lead lengths, tighten all fittings properly to assure they are water proof. All drilled entries require Q Click wire connectors to insure water tight connection. Use of other connectors voids warranty.
   

6. Coil and store field wiring in Junction Box area.
   Note: Label all wiring for future reference.

FOR COMPLETE WATER TIGHT GUARANTEE

PRIMARY WIRING IN (120-277V)
Conduit – Use Installation Kit

• Step 1: Putty
• Step 2: Epoxy
• Step 3: Syringe

Non-conduit – use Q-CLIK NPT.75, Q.750-1E, Q-WIRE 12/2+GND
WARRANTY IS VOID IF THE CORRECT METHOD IS NOT USED.

SECONDARY WIRING OUT (12-24V)
Low voltage wire (non-conduit)

• Q-CLIK
• NPT-or knock outs in bottom of Q-VAULT, .5-.75
• MST to drill into the side of the housing, .5-1.25
• Q-WIRE low voltage marine grade UFB wire (recommended) 10-14AWG
• Standard Q-CLIK insert

Conduit – low voltage, requires Seal Kit (sold separately)

• Step 1: Putty
• Step 2: Epoxy
• Step 3: Syringe

7. Clean debris from the top perimeter and install gasket. SEE DIAGRAM D
8. Install door and tighten the 6 door bolts in the number sequence shown. SEE DIAGRAM E
Note: Nut driver can be used to get bolts seated before final tightening. Proper door bolt tightening must be done with a ratchet wrench using a 3/8“ socket at a maximum torque of 50 in-lbs.
9. Attach the provided Support Bars to the Q-VAULT housing using the 6-32 X 5/8 screws. SEE DIAGRAM F
*OPTIONAL: Concrete Pour Ring Nut & Bolt Installation. SEE DIAGRAM G
10. Level housing and fill hole with gravel to 4“ of below grade. Add soil to surface. SEE DIAGRAM H
All wire entry/exits other than conduit entries MUST use Q-CLIK connectors. Failure to use them will void warranty.
11. Remove cover if installed, be sure to store cover and cover gasket in a clean and dry location.
12. Move field wiring out of the way.
13. Place Q-SET+QZ low voltage luminaire power supply cassette into the Q-VAULT housing.
14. Landscape Lighting: Landscape Lighting: Bring primary field wiring directly into the Cassette’s primary terminal block through open hole.

Primary Connections:

• Ground to ground labeled on terminal block
• Neutral to neutral labeled on terminal block
• Hot to hot labeled on terminal block

INSTALLING Q-SET+QZ

Determine proper lengths and trim to correct length.
Q-SET+QZ Low Voltage Connections:
Connect red wire to +24V on low voltage terminal block.
Connect black wire to – on low voltage terminal block .

SIMPLE AS 1, 2, 3

1. Use putty provided to seal wires in potting well. It is important that the well is liquid tight so that when the re-enterable epoxy is poured, it does not escape out the bottom. Be sure the putty is put into the very bottom of the well to allow ample room for the epoxy. SEE DIAGRAM O

2. A: The 3M-8882 re-enterable epoxy takes several hours to set. When set it will form a into a water tight “jello” consistency.
   B: Mix the two part epoxy together per 3M instructions located on the epoxy packaging.
   C: Push all the mixed epoxy together to one end of the bag. Cut the corner of the bag.

3. A: Using the syringe pull the mixed epoxy into the syringe by pulling the plunger out slowly.
   B: Slowly dispense the mixed epoxy from the syringe into the utilized potting wells. SEE DIAGRAM P
   Note: Potting is now complete

LAST STEP
Final Door Installation
Gasket and door installed only in one direction

• Clean housing area where door gasket will rest
• Reinstall clean door gasket.
  Before Door is Installed
  Put velcro desiccant bag in place. Attach the two velcro loop coins on the desiccant bag to the two velcro hook coins on the underside of the housing door.
  SEE DIAGRAM Q

Note: Install door and tighten the 6 door bolts NOT TO EXCEED 50 IN-LBS. Door bolt tightening must be done with a ratchet wrench using a 3/8” socket.
