DESTRAT VENTILATOR SAFETY
GUIDE
Please read the information in this document carefully
prior to attempting the installation, operation and/or
servicing of the Surna Destrat Ventilator. This document
contains information required to install and operate the
fan. Failure to follow the directions provided could cause
damage to the unit and/or accessory equipment, damage
to building facilities and/or cause serious injury or death
to the operator. Please adhere to all applicable safety
guideline requirements in this document and all electrical
and mechanical jurisdictional codes. Using the Ventilator
in a manner not described in this manual may void unit
warranty.
Prior to providing power to the equipment, inspect the
area for water spills, which may present a shock hazard
to the user. Take extra care to mount accessory electrical
equipment away from areas regularly exposed to
water. Provide secure wire and cable routing to protect
personnel from shock hazards.
Only operate the equipment with an appropriately
sized switch or circuit breaker in place. Only operate
equipment with adequate wire sizes and current carrying
capacity. Consult with a licensed electrician and the
specifications section of this manual before attempting
electrical installation. The switch or circuit breaker shall
be accessible without the use of a tool, shall be easily
accessible to users, shall be clearly marked with “ON” and
“OFF” positions, and shall disconnect all current carrying
conductors simultaneously.
DO NOT use a rope or chain to suspend the Ventilator.
To reduce risk of injury, do not bend the blade brackets
when installing the brackets, balancing the blades, or
cleaning the fan. Do not insert foreign objects in between
rotating fan blades.
7

DO NOT use an extension cord or plug adapters. These
actions may result in a fire hazard or electric shock.
DO NOT operate this unit with damaged power wires. If
the power wires are damaged it must be replaced by the
manufacturer or a qualified/licensed service technician.
DO NOT use this unit to circulate fluids, solids, gases, or
any other substance that is not expressly permitted. This
fan is designed for air ventilation only.
This unit must be connected to a protective earthing
system prior to operation. DO NOT remove the grounded
connection while power is being supplied to the fan.
Doing so presents an electric shock hazard to users and
service personnel.
All wiring must be in accordance with the National
Electrical Code, ANSI/NFPA 70 and local electrical codes.
Electrical installation should be performed by a qualified
electrician.
Ensure that power is o before installation or performing
work on the unit.
To reduce the risk of fire or electric shock, do not use this
unit with any solid-state speed control device.
To reduce risk of injury, it is recommended to mount the
fan at least 10 feet (3.1 meters) above the floor.
This device is intended for indoor use only and should be
protected from rain and flooding.
This equipment is not meant for connection to a duct
system.
A minimum clearance of 36 inches (915 mm) shall be
provided around the fan intake and 72 inches (1,828 mm)
around the shroud to ensure proper air flow and servicing.
After installation, service and maintenance personnel shall
be able to access the power supply and fan blades.
Prior to installation, care must be taken to ensure the
structural integrity of the supporting members when
mounting the fan. Verify the load bearing capacity of any
mounting surface is rated for the load of the Ventilator.

DESTRAT VENTILATOR ORDER
Below is a list of all parts provided with each Surna
Destrat Ventilator unit. The following are included with
the order (quantities are dependent on individual order).
1. Surna Destrat Ventilator fan unit
2. Surna Destrat Ventilator product manual
3. Surna Destrat Ventilator mounting bracket
INTENDED APPLICATION
The Surna Destrat Ventilator is a critical component
of the sealed environment ventilation system. This fan
helps maintain stable air temperatures throughout the
facility's environment by pulling hot, humid air from the
canopy into the terminal unit processing area to cool,
dehumidify and/or heat.
By dispersing the hot, humid air of the canopy
throughout the space, the Surna Destrat Ventilator
is intended to create a consistent, homogenous
temperature and humidity level. Rather than blowing
the air directly down, creating a dome eect, the Surna
Destrat Fan disperses the air to all sides of the space.
For commercial or industrial use only.
10

MECHANICAL
Mounting details are shown in figures 2 and 3.
The unit must be securely supported in compliance
with local codes. Do not use rope or chain to suspend
the Destrat Ventilator. Generally, 14G unistrut is used to
suspend and support the unit. Using provided bolts and
washers, hang the fan from the mounting slots provided
on the top of the unit, taking care to engage all the
threads of the nut and tightening until the fan is secure.
Equivalent support methods are acceptable, provided
structural members have sucient load bearing capacity
to support the fan’s weight. Unistrut supports should
be mounted to the ceiling or support structure using
a minimum size of 3/8 inch (9.5 mm) all-thread and
appropriate spring nuts and washers per Unistrut OEM
installation procedures.
When installing, service clearances must be provided to
maximize performance (proper airflow is critical), and allow
servicing of the unit. Ensure that a minimum of 36 inches
(915 mm) of clearance is provided around the shroud
of the fan, and a minimum of 18 inches (457.2 mm) of
clearance around the fan intake.
CAUTION: Mount with the lowest moving parts at least
10 feet (3.1 meters) above floor or grade level.
All set screws must be checked and retightened where
necessary before installation.
ELECTRICAL
WARNING: Turn o the breaker until all electrical
connections are made.
All wiring shall comply with local and national codes.
The high voltage terminal block should be connected to
your incoming 115V or 220V power wires.
The fan is connected to the power supply through a
socket outlet on the chassis exterior. Do not remove
this plug when in operation or try to operate other
equipment from this connection.
WIRING
WARNING: This unit must be connected to a protective
grounding system.
Before attempting system installation, verify that the
electrical system and wiring are adequate for supplying
the required ampacity to the fan at 115V or 220V. Field
wiring terminals are provided for control connections.
Always employ the services of a qualified electrician
prior to installing and operating the equipment. Making
improper electrical wiring connections could cause
damage to the equipment or servicing personnel.
