Plumbing Installation
The TechPaq installs using standard 2 inch heater unions. The TechPaq uses a standard 12 inch heater vessel. The
TechPaq is designed to allow the heater union nuts to retract fully for installation so it is not necessary to disassemble the
TechPaq or remove the front cover to perform the plumbing installation. Carefully orient the TechPaq in position and
tighten the heater unions.
Mechanical Installation
Each repair installation is different. Depending on the location of existing mounting brackets or straps and the location and
type of plumbing connections you may wish to use the included mounting brackets. The supplied mounting brackets can
be used either by themselves or with existing brackets. For mechanical installation there are four (4) holes in the back of
the TechPaq enclosure to receive the supplied #10 self-tapping screws. Either existing brackets or the supplied mounting
brackets can be attached to one or more of
these mounting locations using a #10 self-
tapping screw. Normally it is not necessary to
remove the front cover to perform the
mechanical installation however, depending on
circumstances of a particular installation, you
may wish to remove the front cover to allow
threading the self-tapping screws from the
inside of the TechPaq enclosure. The mounting
brackets can be attached to supports above or
below the TechPaq. Additionally the supplied
mounting brackets may be connected to each
other using the supplied #10 screws to add
additional length. It is sometimes useful to use
the additional length to provide a mechanical
connection on the side of the TechPaq opposite
the heater union connected to pump one. Also
since the TechPaq is designed to be compact to
fit easily into existing installations you may
chose to use the supplied mounting brackets to bridge to the existing mounting brackets or other support.
Electrical Installation
Check the label on the left side of your TechPaq to find the maximum allowable circuit breaker ampacity. Ensure that the
dedicated circuit is protected by a properly sized GFCI breaker and that the ground is properly sized. Remove the front
cover of the TechPaq. The TechPaq has an electrical entry sized for 1 inch conduit on the left side of the enclosure and
includes a set of reducing washers for ¾ inch conduit. Attach the conduit you are using ensuring that the electrical wires
protrude at least 6 inches beyond the conduit entry. Connect the wires to the barrier strip. The wire size range for 120 volt
packs is #12 AWG to #8 AWG copper conductors. The wire size range for 240 volt packs is #12 AWG to #6 AWG copper
conductors. Do not use aluminum conductors. The neutral conductor connects to terminal position 2 and the line
conductor(s) connects to terminal 1 for 120 volts packs and terminals 1 and 3 for 240 volt packs. The ground connects to
the ground terminal. Also connect all equipment bonding grounds to the grounding terminals on the exterior of the
TechPaq. Be sure to tighten all connections carefully. A loose connection will generate heat that will damage the terminal.
