Starting Up The Unit - S&P TR130 Manual De Uso

Installing Outside Air & Exhaust Air Ducts
Ducts connecting the unit to the outside must be well- insulated.
Vapor barrier is required on both inside and outside of the insulation.
Band or tape inner duct liner to inner flange of appropriate collar.
Drive a sheet metal screw through liner to secure duct spiral wire
to collar. Straighten insulation, and slide outer duct jacket onto
the outer flange of the duct collar. Secure with band or tape.
The vapor barrier should be continuous and sealed against air
and moisture leakage! If not, condensation or ice may form
in cold weather on the duct surface or in its insulation!
The inlets and outlets should be screened against insects and vermin
and shielded from the weather to prevent the entry of rain or snow.
INSTALL FRESH AIR INLET AWAY FROM SOURCES OF CONTAMINANTS.
• Do not locate the fresh air inlet where vehicles may be
serviced or left idling.
• The fresh air inlet should be at least ten feet away from
any exhaust such as dryer vents, chimneys, furnace, and
water heater exhausts or other sources of contamination
or carbon monoxide.
• Never locate the fresh air inlet inside a structure.
Installing Return Air (RA) Ducts
All the stale air returns are connected by ducts to the unit.
Generally, empty stud cavities are used for returns as is often
done with cold air returns for the furnace, using standard duct
boots to connect to six inch pipe at the bottom or top of the
wall cavity. Always be sure to seal all joints with duct sealant
or tape. Some local codes may require metal ducting all the way
from the boots to the stale air grilles. Use rigid ducts to allow the
air to move freely and easily through the ducts. See chart under
System Layout to size your ductwork:
If duct runs are very long (over 25 feet of flex duct for130 CFM
or over 10 feet for 200 CFM each run) or have excessive bends
or elbows or if maximum air flow rates are required, eight inch
insulated flexible duct should be used. The outer flange of the
duct collar can be used for both the inner and outer jacket of
the flexible duct. Care must be taken to insure that the duct is
securely fastened and sealed to the duct collar.
Do not use more flex duct than necessary!
Flex duct is much more resistant to airflow than rigid duct; longer
runs of flex duct will reduce the ventilation performance of your
system. Stretch flex duct and avoid sharp bends.
• Do not connect Dryers directly to the unit.
• Do not connect Range Hoods to the unit.
Installing Fresh Air (FA) Ducts
Use a five foot section of flexible insulated duct to connect the
unit to the ducts at the port labled Fresh Air to the Inside. This
will cut noise transmitted from the unit. Stretch the flex duct
tightly in order to maintain good airflow.

DANGER OF ELECTRICAL SHOCK WHEN SERVICING AN
INSTALLED UNIT.
ALWAYS UNPLUG UNIT BEFORE CONNECTING OR
SERVICING CONTROLS.
Installing Controls
Optional Controls:
S&P offers a variety of controls specifically designed to work with
the TR130/200/300. These include: SPTL (a two wire proportional
timer), SFM (a six wire proportional timer that interconnects to
the furnace blower), and SPBL (point of use push button control).
Other controls that throw an unpowered switch may also be used.
Typical Control Schematic:
Various wiring designs can be used to properly control the unit
and meet safety and code concerns. Consult your electrician for
an electrical design to meet your needs. The schematic below
shows a typical control system: a SPTL proportional timer plus
two SPBL push-button controls.
Up to (6) SPBL Controls, wired in parallel, may be used.

Only (2) SPBL Controls can be directly connected to the SPTL Control.
Wire any additional SPBLs in parallel with the first two.
See installation manuals for the control(s) you select for wiring
diagrams and specific instructions.
If NOT connecting controls to the TR:
Make a jumper out of a short piece of wire. TR will run fulltime
once its power cord is plugged in.

Starting Up the Unit

• Inspect your installation to be sure all duct work is correctly
installed and sealed, that filters are in place, and controls
(if any) are connected.
• Shut and latch the door to the unit.
• Provide 120 VAC power to the unit. It may start immediately.
• Use control, if any, to turn on the unit. Check operation of
the control(s).
• Check that the unit's safety interlock switch turns off the
unit when the door is opened.
