Installation
Filter Installation
TSC060AD unit ships with one inch (25
mm) filters. The quantity of filters is deter-
mined by unit size. Access to the filters is
obtained by removing the indoor fan ac-
cess panel. To modify the unit’s filter rack
to accept two inch (50 mm) filters, re-
move the L-shaped angle attachment
screws and rotate the angles 90 de-
grees.
Reinstall the screws and insert new filters.
Refer to the unit Service Facts (shipped
with each unit) for filter requirements.
Note:
Do not operate the unit without filters.
Field Installed Power Wiring
An overall dimensional layout for the field
installed wiring entrance into the unit is il-
lustrated in Figure 2. To insure that the
unit’s supply power wiring is properly
sized and installed, follow the guidelines
outlined below.
Note:
All field installed wiring must conform to
State and Local codes.
Verify that the power supply available is
compatible with the unit’s nameplate rat-
ings. The available supply power must
be within 10% of the rated voltage
stamped on the nameplate. Use only
copper conductors to connect the power
supply to the unit.
USE COPPER CONDUCTORS ONLY!
UNIT TERMINALS ARE NOT DE-
SIGNED TO ACCEPT OTHER TYPES
OF CONDUCTORS.
Failure to do so may cause damage
to the equipment.
Main Unit Power Wiring
1. The unit is not equipped with an op-
tional factory installed nonfused dis-
connect switch or circuit breaker.A field
supplied disconnect switch must be
installed at or near the unit in accor-
dance with State and Local codes.
2. Location of the applicable electrical
service entrance is illustrated in Figure
2. Complete the unit’s power wiring
connections onto either; the main ter-
minal wire connectors inside the unit
control panel, the field supplied
nonfused disconnect switch (UCD) or
circuit breaker (UCB). Refer to the
customer connection diagram that is
shipped with the unit for specific termi-
nation points.
3. Provide proper grounding for the unit
in accordance with local and national
codes.
Field Installed Control Wiring
An overall layout of the various control
options available with the required num-
ber of conductors for each control device
is illustrated in Figure 6.
Note:
All field wiring must conform to State and
Local codes.
Control Power Transformer
The 24 volt control power transformers
are to be used only with the accessories
called out in this manual. Transformers
rated greater than 50 VA are equipped
with internal circuit breakers. If a circuit
breaker trips, turn “Off” all power to the
unit before attempting to reset it.
HAZARDOUS VOLTAGE
DISCONNECT ALL ELECTRIC
POWER INCLUDING REMOTE
DISCONNECTS BEFORE SERVICING.
Failure to disconnect power before
servicing can cause severe personal injury
or death.
The transformer is located in the control
panel. The circuit breaker is located on
the left side of the transformer and can be
reset by pressing in on the black reset
button.
Controls using 24 VAC
Before installing any connecting wiring,
refer to Figure 2 for the electrical access
locations provided on the unit and
Table 2 for AC conductor sizing guide-
lines, and;
a. Use copper conductors unless other-
wise specified.
b. Ensure that the AC control wiring be-
tween the controls and the unit’s termi-
nation point does not exceed three
(3) ohms/conductor for the length of
the run.
Note:
Resistance in excess of 3 ohms per
conductor may cause component failure
due to insufficient AC voltage supply.
c. Be sure to check all loads and conduc-
tors for grounds, shorts, and mis-wir-
ing.
d. Do not run the AC low voltage wiring
in the same conduit with the high volt-
age power wiring.
e. Route low voltage wiring per illustra-
tions on page 24.
