INTRODUCTION:

The Schaefer Ventilation Equipment, LLC. BIGDOG

fan is one of the most innovative and efcient fans

available in the world today. Our BIGDOG can be used

to move large volumes of air, create velocity for cooling

and run on low speed to de-stratify the air in your

building. It does all of these applications efciently and

quietly. The BIGDOG can be used as a stand alone

ventilation system or to improve your existing ventila-

tion. This brief manual is recommended reading before

installing the new system and will also be handy during

the installation. (See Figures 1 and 1A)

PROPER DESIGN AND INSTALLATION

Your sales professionals have given you a

recommendation for placement, orientation and

operation. If you are unsure then call our

800-779-3267 number for customer care.

It is up to you as the owner to ensure that your

building is made ready for the system.

• We recommend that you hire licensed and insured

consultants and contractors to install this equipment.

The installation is by design made simple for skilled

tradesmen.

• We recommend that the receiving of this system be

coordinated and veried to avoid lost time due to

misplaced equipment.

To achieve the full performance of the BIGDOG fan we

recommend using a Variable Frequency Drive (VFD). The

VFD will allow you to manually run your fan from low

speed (300 watts) to high speed (2200 watts). You can also

add one of our temperature controls that can be wired to

the VFD and change the speeds based on

temperature, time or humidity. Call our technical

support line (800-779-3267) for a list of Schaefer

Ventilation Equipment, LLC. approved controls. It is

important that controls are sized properly for the amp

loading of the fan.

BIGDOG INSTALLATION PREPARATION

Review this entire manual with the installation

team and share information with necessary

personnel.

 Physically conrm the arrangements and

locations of the system BIGDOGs and

controls. Verify your order documents for the

system conguration.

 There are several components that can be

assembled on the oor for economical

BIGDOG system installations.

Consult your construction professionals.

 Consult with your professional construction team

and review this installation.

 Review and prepare your electrical and structural

building components.

Plan to receive and store the system components.

 CHECK THE FREIGHT IN AND INSPECT IT

WHILE THE DRIVER IS PRESENT. REPORT

ANY DAMAGES TO THE DRIVER AND

SCHAEFER CUSTOMER CARE.

 Store the freight in a location that has proper

access for material handling.

 Set the

storage

space aside.

All the oor work should be in a dedicated

workspace to begin the installation. The fans have

heavy eye loops for handling and hanging. The

BIGDOG is heavy and awkward to handle. Please

use caution and maximum safety when handling.

 As an option, the variable frequency drive can

be resilient mounted to this side of the fan. This

requires drilling ¼" holes in the BIGDOG hous-

ing. Install the VFD onto the BIGDOG while it is

on the ground using grommets or 1/8" thick

rubber washers and 1/4-20 x 2" bolts with captive

nuts and washers. The VFD shall be positioned

upright to allow airow out both sides of the heat

sink.

 When installing this fan in high moisture applica-

tions, a waterproof connector and drip loop in the

wire should be used.

 Check sheaves and belts for alignment and

tension in case they have moved during shipping.

They should be adjusted if required.

 The bearings can be inspected and greased as

required. We recommend yearly greasing and

maintenance. Grease nipple is located on the

back of the blade shaft.

 Inspect for defects or missing parts.

Discrepancies shall be reported to Customer

Care. (Figures 3, 4 and 9)

Prepare to move and erect the BIGDOG.

CEILING SUSPENDED METHOD

Install the fans in the locations directed by your

system provider.

Use Grade 80 or 100 Chain or Aircraft Steel Cable that

can handle minimum of 425 LBS of hanging weight.

Follow the chain or cable manufacturer’s directions

for installing and connecting the suspension sys-

tem components. All components must be rated for

OVERHEAD LIFTING.

There are 4 eyelets factory installed on the fan. These

metric eyelets are M10 x 75 shanks with 30 mm loops.

These eyelets are placed near the corners of the fan

housing at approximately 54" center to center.

Cable or chain shall be installed vertically to the

ceiling at up to a 45 degree angle away from the center

of the fan.

Ceiling structure fasteners shall be done with Heavy

Beam Clamps and 3/8" Eyelets or drilled 3/8" eyelets

with heavy backing washers and double heavy nuts.

• Z-Purlins may require reinforcement to prevent

twisting.

• Be sure to evaluate that the structure is strong

enough to support the 425 LBS BIGDOG.

POLE MOUNT AND WALL MOUNTED

METHOD

Pole Mount assembly anchors to concrete oor.

Use with Straight or Angled fan mount.

Wall brackets can be mounted to columns or walls.

Use with Straight or Angled fan mount.

The BIGDOG fan will be cantilevered away from the

mounting structure by approximately 62".

Refer to the BIGDOG Pole & Wall Mount specica-

tions sheets to review the forces that will be exerted.

DEFLECTOR SUPPORT BRACKETS

AND INSTALLATION

Deector support Brackets are to be installed on the

inside of and on opposite at sides of the BIGDOG

housing. The brackets are located on the sides that

have a curved bottom edge contour with holes drilled

to mount the deector brackets.

There is a difference in the bracket arrangements for

the one-way (See Figure 6 and 7) or two-way airow

(See Figure 8).

Use (12) M8 x 30mm bolts, the (12) nylock nuts

and (24) 8mm x 25mm fender washers to mount the

deector brackets.

Install the turning vanes in-between the brackets

with the (24) M8 x 40mm bolts, and the (24) 8mm x

25mm fender washers. Notice the difference between

two-way or one-way airow. (See Figures 7 and 8).

Finger thread and snug these bolts being careful not

GENERAL NOTES FOR VFD SYSTEMS

1. We recommend that a licensed electrician perform

all electrical work per Federal, State and Local

Electrical and Safety Codes.

2. The Building Voltage system must be understood.

Each voltage system has a variable frequency

drive (VFD) that matches.

a. The BIGDOG Motor requires 230V or 460V

3 phase alternating current 60-Hertz power.

See the nameplate and/or motor tap box for

motor terminations.

i. Use the 230V (Low Voltage) motor pigtails

for 240/1 and 200-230/3 wiring systems.

ii. Use the 460V (High Voltage) motor pigtails

for 460/3 wiring systems.

b. The VFD is specied for the 240/1/60, 208-

230/3/60 and 460/3/60 voltage system in your

building. See VFD manufacturer’s installation

manual for specic terminations and settings.

3. The VFD shall not be located where corrosive

gasses and/or chemicals, water and condensation

are present. An Optional VFD Rated NEMA 4/4X

is available for special high humidity applications.

a. Consult your licensed electrician for special

occupancy and exposure requirements.

b. The VFD comes standard as a NEMA 1

usage. NEMA 1 means indoor clean and dry

locations. Moisture, dust, water, chemicals,

gases that occur where the VFD is installed

demands that the VFD is protected. Severe

Duty Locations require specic protection.

The NEMA Type 4/4x enclosure is considered

non-corrosive and moisture proof.

4. The VFD shall not be located near furnaces or

panel heating devices. Avoid heat sources.

5. The VFD shall not be located near magnetic

detection systems. Special optional lters are

available.

6. Do not install anything in the wiring between the

VFD and the Motor.

7. GROUNDING IS IMPORTANT FOR PEOPLE

AND ELECTRONIC SAFETY.

a. Be sure that the buildings electrical system is

properly grounded.

b. Be sure to terminate the ground systems per

the VFD instruction manual.

8. Poor electrical power systems demand special

considerations.

a. Consult with experienced Electrical Engineer

and/or Certied Electrician.

b. Consult with the VFD manufacturer.

c. Call Schaefer Ventilation Equipment, LLC.
