Connect Piping - oventrop OVSOL System 5 Manual

Connect two bottom supports with the L-bracket and
tighten screws. Make sure that the bottom clips line up
with the manifold condenser holes above for square.
Connect Piping to the Manifold
With each roof mounting kit, there are adapters to pipe to
the manifold. Included are:
Two compression tees to attach to the supply and
l
return terminations on each collector manifold or collector
array;
Two copper pipe adapters that adapt from 22mm
l
copper pipe size (at compression tee) to 3/4" copper pipe.
Also included in some roof kits are two stainless steel
flexible hoses and additional compression couplings for
copper pipe adapters.
NOTE: Use 1/2" copper supply and return for collectors
with up to 24 tubes (one 8- and one 16-tube collector)
and 3/4" copper for collectors with a 4- to 16-tube
collector array. Preferably use Type L. Do not use PEX
plastic tubing. PEX tubing cannot withstand
temperatures above 200°F and will fail.
Always insulate outdoor tubing with high temperature
Insultube and weather proofing against UV degradation.
Use insulation with a wall thickness of at least 3/4".
Install compression tees at supply and return on collector
manifold. Make sure the compression ring is well onto
the copper pipe terminating the manifold so that the
compression ring will not slide off the pipe as the
compression nut is tightened.
Install the Thermowell, which is for the collector sensor,
on the return outlet tee. Solder the threaded thermowell
into the tee before installing the compression tee to the
header. Smear some heat transmission paste on the
sensor and insert the sensor into the Thermowell. Lock
sensor into place with set screw on the Thermowell.
Install the manual air vent on the manifold's supply inlet
tee. If the piping rises above the collector on a closed
loop system, add an additional manual air vent at the
highest point of the loop.
