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.

PIPE HEATER

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.

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.
