Lifting Recommendations
Before preparing the unit for lifting,
estimate the approximate center of
gravity for lifting safety. Because of
placement of internal components,
the unit weight may be unevenly
distributed. Approximate unit
weights are given in Table 1.
must be capable of lifting the unit
weight with an adequate safety factor.
The use of under-capacity lifting
devices may result in severe personal
injury or death and can seriously
damage the unit.
The crated unit can be moved using a
forklift of suitable capacity. For lifting
the unit, attach lifting straps or slings
securely to the lifting holes at each
corner. Use spreader bars to protect
the unit casing from damage. Test lift
the unit to determine proper balance
and stability.
Clearances
Provide enough space around the
unit to allow unrestricted access
to all service points. Refer to unit
dimensional data for minimum
required service and free air
clearances. Observe the following
points to insure proper unit operation.
A. Do not install the unit under a low
overhang. Condenser discharge
clearance is not less than 2.5 mm.
Important: Do not obstruct condenser
discharge air. This can result in warm
air recirculation through the coil.
B. Do not locate the unit in a position
where runoff water can fall into the
fan discharge openings.
C. Condenser intake air is supplied
from three sides of the unit. Adhere
to the minimum required clearances
given in dimensional data.
Unit Mounting
“For ground level installation, the
unit base should be adequately
supported and hold the unit near
level. The installation must meet the
guidelines set forth in local codes.”
The support should extend two inches
beyond the unit base channels at all
points. The unit and support must be
isolated from any adjacent structure to
prevent possible noise or vibration
problems. Any ground level location
must comply with required clearances
given in dimensional data.
Warning: On-sight lifting equipment
Caution: Use spreader bars to
prevent lifting straps from damaging
the unit. Install bars between lifting
straps. This will prevent the straps
from crushing the unit cabinet or

Refrigerant Piping Guidelines
Refrigerant Piping
To ensure the return of oil in the
refrigerant lines, it is necessary to
follow these recommendations:
1. Select the tube lengths with care

meters of tube to use up. Refer to
table 2 for tube sizes.
2. Pitch all horizontal suction lines
down towards the unit to assist
gravity oil drainage back to the
compressor.
3. Avoid creating large oil traps in
horizontal suction lines as this will
reduce oil circulating in the system
and may eventually lead to failure
of the compressor.
4. A small oil trap at the end of a
horizontal suction line before a long
vertical riser (of more that 2.5
metres) has the advantage of
assisting the high velocity gas to
carry the oil up the vertical pipe.
5. Liquid lines require no special
installation techniques as the liquid
refrigerant R-22 and the oil mix.
The densities of the refrigerant and
oil are near enough the same so
any movement of liquid refrigerant
will carry oil with it.
6. The installation of a liquid line
sight is recommended. It is very
useful during the maintenance
procedures.

Refrigerant Charging and Evacuation
Note: Each TTA unit ships with holding charge.
System Evacuation
1. After completion of leak check,
evacuate the system.
2. Attach appropriate hoses from
manifold gauge to gas and liquid
line pressure taps.
Note: Unnecessary switching of
hoses can be avoided and complete
evacuation of all lines leading to
sealed system can be accomplished
with manifold center hose and
connecting branch hose to a cylinder
of R-22/R407C and vacuum pump.
3. Attach center hose of manifold
gauges to vacuum pump.
4. Evacuate the system to hold a
350 micron (-76 cm.Hg) vacuum.
5. Close off valve to vacuum pump
and observe the micron gauge.
If gauge pressure rised above
500 microns in one (1) minute,
then evacuation is incomplete or
the system has a leak.
6. If vacuum gauge does not rise
above 500 microns in one (1)
minute, the evacuation should be
complete.
Caution: Do not connect a
dual-circuit outdoor unit to a single
circuit evaporating unit. (blower)

Pressure reading should fall
approximately at the points shown
by the pressure curves in Service
Facts. Add or remove refrigerant
(gas only) as required to obtain
correct head and suction pressure.
Check suction line superheat and
condenser sub-cooling to ensure
the unit is operating properly.
4. Disconnect all power to the unit.
5. Remove the charging system from
the unit and close the opening in
the bottom of the control box with
the pivotal cover before attempting
to replace access panel.
6. Replace all panels.
Additional Charge
Refrigerant suitable for a tube length
of 12 to 25 feet is recommended in
Table 3. When the tube is longer than
25 feet, additional charging is
necessary. For the additional amount,
using the table 4 for recommended
amounts:
Caution
Freon Gas only.
Always evacuate air from the tubing
before adding refrigerant.
Add refrigerant through the
charging port of liquid line valve
after the completion of evacuation.
The refrigerant provided by the
manufacturer meets all the
requirements of our units. When
using recycled or reprocessed
refrigerant, it is advisable to ensure
its quality is equivalent to that of a
new refrigerant. For this, it is
necessary to have a precise
analysis made by a specialized
laboratory. If this condition is not
respected, the manufacturer’s
warranty could be cancelled.
