The Phoenix Mini-Guardian HEPA System is the compact, variable
air speed version of our popular Phoenix Guardian HEPA System.

Maximum delivered air flow with 3-stage filtering in place is over
415 CFM and will clean one air change of a 14 x 14 foot room in
less than four minutes while drawing less than two amps of power.
This makes the Mini-Guardian HEPA System perfect for smaller
remediation projects where space is at a premium and reduced air
flow essential. A template on the intake grill makes it possible to
take air-flow measurements with the Phoenix Kestrel 3000 Multi­Meter.

TS-261B

The Mini-Guardian HEPA System’s 3-stage filter design with true
HEPA filtration will remove virtually all hazardous particles from
the air and an optional fourth stage filter of activated carbon
and potassium permanganate will absorb a wide range of odors
and gases. The unique 24” canister HEPA, manufactured for the
Phoenix Mini-Guardian HEPA System, contains nearly 200 square
feet of surface area. This allows maximum air-flow and significantly
extends filter life.

• Less than 2 amps

• Compact design

2 Operation

2.1 Handle Assembly Procedure

Tools Required: Hex Key, 8mm (Supplied with packed
parts)

1. Remove the handle assembly (consists of two
handle brackets and handle tube), two metric
socket head cap screws M10 x 35mm length,
and 8mm hex key from the packed parts supplied
with the unit.

Dealer’s Name_____________________________

Read the operation and maintenance instructions
carefully before using this unit. Proper adherence to these
instructions is essential to obtain maximum benefit from
your Phoenix Mini-Guardian HEPA System.

2. Locate the two mounting holes for the handle
assembly on the Mini-Guardian HEPA System cabinet.
They are located in close proximity to the top of the
cabinet near the corners. A lock nut should be visible
through each of the mounting holes and is held in
place by a retainer plate secured to the cabinet shell.
Verify lock nut is visible in each mounting hole.

4. Tighten each of cap screws using the 8mm hex key
until the handle assembly is secured against the
cabinet surface and all space between parts is
eliminated.

2.2 Transporting the Phoenix

The Phoenix Mini-Guardian HEPA System should be upright
when transported by vehicle. It may be tipped on to its
back for loading and moving by hand or for use on location.

Figure 2: Mounting holes

3. Place a socket head cap screw (M10 x 35mm)
into each of the holes in the handle end brackets.
Position the handle assembly up against the Phoenix
Mini-Guardian HEPA System cabinet so as to align the
cap screws with the mounting holes in the cabinet.

It may be necessary to tilt the handle assembly

up at a slight angle in order to align the screws
with the lock nuts. Use the 8mm hex key to press
the cap screws into the mounting holes and engage
the threads of the lock nuts.

2.3 Location

Note the following precautions when locating the Phoenix
Mini-Guardian HEPA System:

· It is designed to be used INDOORS ONLY.

· If used in a wet area, plug it into a GROUND FAULT

INTERRUPTER.

· DO NOT use the Phoenix Mini-Guardian HEPA System as
a bench or table.

· The air inlet on top & the side outlets should be at
least 1 foot from walls and other obstructions to
airflow.

2.4 Electrical Requirements

The Phoenix Mini-Guardian HEPA System can be plugged
into a grounded 15 Amp circuit. It draws about 2 Amps
with clean filters and no ducting. The amp draw will
decrease slightly with added ducting and as the filters load
with particulate.

If an extension cord is required, it must have a minimum of
18 gauge conductors if 25 feet long or less and 16 gauge
conductors if greater than 25 feet long.

2.5 Air Ducting

2.5A Inlet Ducting

Occasionally the area to be filtered is difficult to access
and/or the unit cannot be located in the area. In such
cases, the air can be ducted to the unit’s inlet.

A round 12” diameter flexible duct can be attached to the
unit inlet on top. It connects by placing the wire in the duct
under the four tabs on the top. It may be removed after
use for easier transport and storage. Flexible 12” duct is
available from Therma-Stor LLC.

Figure 5: Inlet ducting

2.5B Outlet Ducting

A detachable rectangular exhaust collar is supplied that
will allow 10” round lay-flat plastic duct to be attached to
the Phoenix Mini-Guardian HEPA System outlet. Lay-flat
plastic ducting is available from Therma-Stor LLC.

To attach ducting to a collar, remove the collar from the
unit by sliding the collar upward out of the guide. Put
the plastic duct end through the collar center. Roll the
duct end outward so that it over-laps the outside of the
collar. The duct will hook over the collar, preventing it from
slipping off.

2.6 Negative Air Ducting

The Phoenix Mini-Guardian HEPA System can be used
to filter and exhaust air from a space. By exhausting
to outside the space, the space will be under a slight
negative pressure. This will help prevent airborne particles
from leaving the space, since the negative pressure will
draw air in through openings in the space’s exterior.

The quantity of air exhausted depends on how the unit is
ducted and what speed is used. A duct can be directed
outside. Cover the other exhaust openings to direct all the
filtered air outside. This would result in up to 400 CFM
being exhausted on high speed and an equal amount of
fresh air being drawn in.

CAUTION: Exhausting too much air from a space with open
combustion devices (e.g. furnace, fireplace or water heater)
can cause those devices to backdraft. This can contaminate
the space with potentially fatal gases.

In such cases, the Phoenix Mini-Guardian HEPA System
must be used in one of the following three ways:

A. As a filtering unit only. Exhausting no air from the

space and thus causing no negative pressure or
backdrafting.

B. Exhausting a very limited amount of air which does not

cause backdrafting. In case B, the open combustion
devices must be thoroughly checked to guarantee that
they do not backdraft while the Phoenix Mini-Guardian
HEPA System is running.

C. Direct the outlet duct from the Mini-Guardian HEPA

System to the room with the open combustion
device(s). This will positively pressurize the room,
thus preventing backdrafting. As in case B, those
combustion devices must be checked after the Mini­Guardian HEPA System is running to guarantee that
they are not backdrafting.

Figure 6: Outlet ducting

The duct can be directed outside, exhausting a portion of
the filtered air. The rest of the filtered air is recirculated
inside the space. Blocking the other supply holes will
determine the amount of air that is exhausted. By
adjusting the blocking plates over the supply openings, the
quantity exhausted can be adjusted down to no flow.

2.7 Power/Speed Control

The power/speed switch is located in the recessed cavity
on the unit front. When turned on to any speed, it powers
the impeller fan and hour meter.

Occasionally the impeller fan may not start on low speed.
If this occurs, rotate the speed control to high speed until
the impeller fan starts, then adjust it to a lower speed.
