Safety Information
Be sure all power sources are turned off before checking the electric wiring or
appliances to avoid electric shock.
Do not run fan if cover or case is removed. This is to avoid electric shock.
All units are pressurized with dry air or nitrogen gas. All units must be evacuated
before charging the system with refrigerant. Keep finger away from moving parts.
Avoid touching refrigerant lines. Some parts are very hot and can cause burns.
Avoid contacting sharp edges or coil surface that are a potential injury hazard.
Avoid touching the units or electric box in wet hands to prevent electric shock.
Please call the specialized installation company or trained personnel when you installing,
moving, operating of the unit.
Field wiring must confirm to the requirements of units’ electric specification.
Inspection
A person at the job site to receive material holds responsibility. Each shipment should
be carefully inspected against the bill of lading. The shipping receipt should not be
signed before careful inspection. Check carefully for concealed damage. Any shortage
or damages should be reported to the delivering carrier. Damaged material becomes the
delivering carrier’s responsibility, and should not be returned to Turbo air unless prior
approval is given. Check the serial tag information with invoice. Report any
discrepancies to Turbo air sales representatives.

Recommended location methods of Unit Cooler.
1. Avoid placing Unit Cooler close to doors. Install like Figure 3 or Figure 4.
2. Avoid having them face each other when installing multiple units. Install like Figure 5
3. Recommended placement when installing multiple units see Figure 6.

Locate evaporators so that air pattern
covers all of the room. Do not restrict the
inlet or outlet air stream. When installed,
there should be 12”clearance from
bottom of the unit. Always avoid
placement of unit coolers directly above
doors and door openings.
Most evaporators can be mounted with
rod hangers, lag screws or bolts. (use
3/8” and 5/8” stainless steel bolts) Refer
to Figure 7. Mount the unit level so that
condensate drains properly. When using
rod hangers, allow adequate space
between the top of the unit and the
ceiling. (NSF Standard 7). The area
above the unit cooler must be sealed or
exposed in such away to allow hand
cleaning without the use of tools. When
lagging or bolting unit flush to the
ceilings, seal the joint between the top
and the ceiling with an NSF listed sealant.
Ends of open hanger channels must be
sealed to prevent accumulation of foreign
material.
Refer to Figures 1 through 4. Air flow
distance must be considered when
coolers or freezers will not accommodate
all required evaporators on one wall.
Refer to Figure 7. Traps on low
temperature units must be outside of
refrigerated enclosures. Traps subject to
freezing temperatures must be wrapped
with heat tape and insulated.

Unit Cooler Piping.
When brazing refrigerant lines, an inert
gas should be passed through the line at
low pressure to prevent scaling and
oxidation inside the tubing. Dry nitrogen
is preferred.
Use only a suitable silver solder alloy on
suction and liquid lines. All piping must
be adequately supported to prevent
vibration and breaking.
Tube clamps should have a gasket
surface to prevent abrasion.
The system as supplied by Turbo air was
thoroughly cleaned and dehydrated at the
factory.
Foreign matter may enter the system by
way of the evaporator to condensing unit
piping.
Therefore, care must be used during
installation of the piping to prevent
entrance of foreign matter.
Use only refrigeration grade copper
tubing properly sealed against
contamination.
Figure 8. Suction piping installation on an
evaporator.
Figure 9. suction piping installation on
multiple evaporators.
Figure 10. Installation of expansion valve
bulb.
Refer to Figure 8 through 9. Suction line
risers must be carefully selected, have an
oil trap at the bottom and at 15 foot
intervals up the riser. They should be the
same size as the vertical riser connected
to its outlet. Riser should not be larger in
diameter than horizontal runs.
Refer to Figure 10.
Expansion valves are supplied with clamp
for securing bulb to the suction line. The
bulb must be secured at the evaporator
outlet, on the side of a horizontal run of
suction line, before any trap.

7
Do not over tighten bulb clamps or
deform the bulb in anyway. Install all
refrigeration system components in
accordance with applicable local and
national codes and in conformance with
good practice required for the proper
operation of the system.
All piping must be protected where it
passes through walls or ceilings.
Precautions should be taken to see that
the piping does not touch any structural
the transmission of vibration into the
building.
The piping chase must be thoroughly
sealed to protect the tube and prevent
ambient air from entering the refrigerated
space. Seal around the drain line where it
passes through the wall. Air leaks can
cause equipment problems. Damage the
structure and product, increase load,
increase operating cast, and can cause a
safely hazard. Eliminate all air leaks.

1. All line size are basic for O.D type L copper tube. The above table is maximum suction size and
riser size should not exceed horizontal size.
2. Suction line size should be selected at pressure drop equivalent to 2。F, and reduce estimate
of system capacity accordingly.
3. For easy oil return, use U trap in suction line.
4. Consider double suction risers, if capacity control can reduce capacity 35 below.
