INSTALLATION, OPERATION AND MAINTENANCE MANUAL

SER 1504, SER 1504N, SER 2004, SER 2004N, SER 3204D & SER 3204N

Your ventilation system should be installed in conformance with the appropriate state requirements or in the
absence of such requirements ASHRAE’s “ Good Engineering Practices”.

IMPORTANT - PLEASE READ THIS MANUAL

BEFORE INSTALLING UNIT

CAUTION - Before installation, careful consideration must be given to how this system

will operate if connected to any other piece of mechanical equipment, i.e. a forced air furnace
or air handler, operating at a higher static. After installation, the compatibility of the two pieces
of equipment must be confirmed by measuring the airflow’s of the Energy Recovery Ventilators
by using the balancing procedure found in this manual.It is always important to assess how
the operation of any ERV may interact with vented combustion equipment (i.e. Gas Furnaces,
Oil Furnaces, Wood Stoves, etc.).

NEVER - install a ventilator in a situation where its normal operation, lack of operation or

partial failure may result in the backdrafting or improper functioning of vented combustion
equipment!!!

Sizing (Example) for maximum airflow normally required.

ERVs are typically sized to ventilate the whole house at a minimum of 0.35 air changes per
hour. To calculate, simply take the square footage of the house (including basement) and mul­tiply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by 0.35.
Example: Sq Ft of House 1100

Basement 1100 (if applicable)

Total Sq Ft 2200

Height of ceiling x 8

Cubic volume 17600

/ 60

Maximum airflow required (CFM) 293

x 0.35

103

* Always consult your local code for sizing requirements in your area.

PORT SELECTION (Reversing Unit) Units are shipped
indicating airflow (see "Dimensions & Airflow" on next page).
These ports can be selected on site by the installer and
changed around as needed. IE "Exhaust Air From Building"
could be changed to "Air From Outside" and "Exhaust To
Outside" switched to "Air To Building". The same is true for
the other ports. This gives the installer greater flexibility in
placement of the unit and ductwork.

OPERATION

An Energy Recovery Ventilator (ERV) is designed to bring in fresh air into the building while exhausting an equal amount of stale air. During colder
months, utilizing the heat recovered from the stale air before it is exhausted outdoors warms the cold fresh air. At the same time, humidity
contained indoors is transferred back to the incoming fresh and dried air.
During warm and humid months, the ERV will cool the incoming outdoor air by using the cool air-conditioned air that is being exhausted from
indoors while allowing the humidity contained in the fresh air to be transferred to the exhaust air.

Fantech ERV’s are designed to run continuous or on intermittent, giving the homeowner complete control over their air quality. Continuous low
speed ventilation is recommended, which will help eliminate carbon dioxide, voc’s and other gases as well as freshen up the home. Intermittent high
speed ventilation can be obtained through a variety of optional remote controls found in this manual.

The entire line of SER series Energy Recovery Ventilators comes equipped with Fantech's new electronic uni-control board which offers a wide vari­ety of features making it the ultimate ventilation control system. Fantech engineers have used the latest technology to provide solid, trouble free oper­ation under any conditions.

The Fantech uni-control board offers stand alone operating capabilities as well as an exclusive 2 wire communication to most external controls. The
trouble-free optional controls include: two different rotary dial dehumidistats, an air quality sensor (3 wire communication required), a 15 minute
remote push-button timer, as well as the most sophisticated line of remote wall mounted controls, the Intellitek EDF5 (5MR).

An on-board diagnostic LED helps find problems quickly and efficiently. For example the LED can be used to signal a broken or shorted electronic
wall control wire. Electronic air temperature probe gives this board accurate readings in order to minimize unnecessary defrost operation, and the on­board jumpers provide the user with the option of adjusting defrost time and sequence to optimize performance under abnormal conditions. The
defrost operation is automatic and is usually never adjusted.

3. Defrost (on selected models)

The automatic defrost cycle consists of a fan shutdown. When the supply air stream temperature goes below ­5°C (23°F), the supply motor shuts down and the exhaust motor goes into high speed. Ambient air is passed
through the unit for a period of 5 minutes. The supply motor will then re-start and run at the preset speed. The
exhaust motor will also slow down to the preset speed, and the unit will operate in the run cycle for 25 min­utes. This fan shutdown defrost cycle continues until the supply air stream rises above 0°C (32°F).

MODES OF OPERATION

1. Continuous / Ventilation Mode

In this mode of operation both fans
are operating and exchanging air with
the outside. The energy recovery ven-

tilator (ERV) constantly exchanges
the air at the rate you select, either at low or medium speed, and switches
to high speed when activated by an optional remote control. The "Low"
and "Med" fan speed selection will cause the unit to operate in continuous
exchange mode at an exchange rate of 35% and 50% maximum airflow
rating respectively. Continuous mode is recommended, since pollutants
are slowly but constantly being generated in your house.

2. Intermittent / Standby Mode

The system is always on standby and operates
at high speed when activated by an optional
remote control. "Standby" should be selected if
the user wishes to stop the unit from

continuous exchange. We recommend that
the "Standby" mode only be used if your system is equipped with an
optional external control, in which case, the unit would activate to
"High" fan speed, until the control is satisfied and then return to
standby (off).

15-min Timer - The 15-minute remote timer is typically installed in areas
where contamination such as moisture and odors, are produced. Simply push
the button and the ERV will activate to high speed for 15 minutes. Up to 5
electronic timers can be installed in parallel throughout the building at a
distance of up to 500 feet (152 meters) from the ERV.

Air Quality Sensor - The wall mount Air Quality Sensor (AQS) monitors indoor
air quality and activates the override mode when carbon monoxide,
formaldehyde, benzene, volatile organic compounds and other pollutants are
detected. The unit will then return to normal mode once the air pollutants are
reduced to a pre-determined lower level.

* This control is not a warning device.

Dehumidistat II - The wall mount dehumidistat II offers the same features of
the dehumidistat I plus additional off/on control for the ERV. Dial illuminates
when in override mode.

Dehumidistat I - The wall mount dehumidistat monitors the humidity level in
the area it is installed. When the humidity level rises above the desired set­point, the ERV will activate to high speed/override mode. Once the humidity
level returns to desired condition, the unit will return to the normal mode.

To avoid window
condensation:

• If a dehumidistat or EDF
control is installed, the
humidity setting should be
raised to its highest setting
(e.g. 99% on EDF) when
using an ERV during warm
and humid months.
Otherwise, the ERV may
stay on HIGH speed,
bringing in more humid air
indoors.

PRACTICAL
TIPS

OPERATION (CONT'D)

* All controls are low voltage. 18 to 24

gauge wire is recommended.

OPTIONAL REMOTE CONTROLS

*

NOTE:

A dehumidistat is ideal for
use in energy efficient
houses where indoor
humidity (during the
heating

season) is higher
than outdoor levels. High
humidity is a major cause
of structure damage and
IAQ problems such as mold
and mildew.

NOTE:

The override speed cannot
be set at a fan speed lower
or equal to the normal
operating fan speed. For
example, if the unit is
normally operating at a
medium fan speed, the
override fan speed will be
automatically set to high.

NOTE:

EDF5 model, changing the
override speed will change
default override speed for
other external controls.

EXAMPLES:

If on the EDF5 control, you
have set the override
control at medium, and
you start an external
remote control (15 min.
timer), the unit will run at
medium speed for 15 min.

INSTALLATION

PRACTICAL TIPS

3 Hang the unit by

slipping a link onto the
hanging hooks, making
sure the unit is level.

2 Attach a hanging chain

(provided) to each 10 3/4”
(19 mm) bolt (provided) in
the top 4 corners of the
unit and tighten.

1 Place Fastening hooks

on the strapping board
or the floor joists.

1 Install the drain nipple.

Installing Drain Line - Units with defrost
Through normal operation and during its defrost mode, the ERV may produce some condensation.
This water should flow into a nearby drain, or be taken away by a condensate pump. The ERV and
all condensate lines must be installed in a space where the temperature is maintained above the
freezing point. A “P” trap should be made in the drain line. This will prevent odors from being
drawn back up into the unit.

MOUNTING *

LOCATION

The ERV should be located in a conditioned space where it will be possible to conveniently service
the unit. Typically the ERV would be located in the mechanical room or an area close to the out­side wall where the weatherhoods will be mounted.
Connecting appliances to the ERV It is not recommended, including:

- clothes dryer

- range top

- stovetop fan

- central vacuum system

These appliance may cause lint, dust or grease to collect in the ERV , damaging the unit.

NOTE: Connecting any of these type of appliances to the ERV will "void" your warranty

19

3 Push the hood into

the opening. Attach
the hood to the
outside wall with
mounting screws.
Repeat the installation
procedure for both
the Supply and
Exhaust hood.

2 Pull the insulated

flexible duct through
the opening until it is
well extended and
straight. Slide the
duct’s inner vinyl
sleeve over the hood
collar and secure, pull
the insulation over the
duct and then the
vapor barrier over the
sleeve and secure
with duct tape.

4 Using a caulking

gun, seal around
both hoods to
prevent any
leaks.

1 Using the collar of

the outside hood,
outline the intake &
exhaust holes to be
cut. The holes should
be slightly larger than
the collar to allow for
the
thickness of the
insulated flexible
duct. Cut a hole
for both the intake
and exhaust hoods.

• Decide where your intake and

exhaust hoods will be located.

PRACTICAL
TIPS

INSTALLING DUCTS GOING TO / FROM OUTSIDE

A well designed and installed ducting system will allow the ERV to operate at its maximum efficiency.
Always try to keep duct runs as short and straight as possible.

See Installation Diagrams for installation examples.

INSTALLING THE DUCTING
TO THE WEATHERHOODS

The inner liner of the flexible insulated duct
must be clamped to the sleeve of the weath­erhoods (as close to the outside as possible)
and to the appropriate port on the ERV. The
insulation should remain full and not be
squished. The outer liner, which acts as a
vapor barrier must be completely sealed to
outer wall and the ERV using tape and or
caulking. A good bead of high quality caulk­ing (preferably acoustical sealant) will seal
the inner flexible duct to both the ERV port
and the weatherhood prior to clamping.

To minimize air flow restriction, the flexible
insulated duct that connects the two outside
weatherhoods to the ERV should be stretched
tightly and be as short as possible.
Twisting of folding the duct will severely
restrict air flow.

Locating the Intake
Weatherhood

• Should be located upstream (if

there are prevailing winds)
from the exhaust outlet

• At least 4' - 6’ (2m) from the

exhaust weatherhood

• At least 6’ (2m) away from

dryer vents and furnace
exhaust ( medium or high effi­ciency furnaces)

• A minimum of at least 6’ (2m)

from driveways, oil fill pipes,
gas meters, or garbage con­tainers

• At least 18” (457mm) above

the ground

• At least 3’ (1m) from the cor-

ner of the building

• Do not locate in a garage, attic

or crawl space

Locating the Exhaust
Weatherhood

• At least 6’ (2m) from the

ventilation air intake

• At least 18” (457mm) above

ground

• At least 3’ (1m) away from the

corner of the building

• Not near a gas meter, electric

meter or a walkway where fog
or ice could create a hazard

• Not into a garage, workshop

or other unheated space

When installing the weather­hood, it’s outside perimeter
must be sealed with exterior
caulking.

CAUTION: In humid climates, it may be "preferable" to have a dedicated ducting system to the house

for the ERV instead of connecting the ERV to the central air-conditioner. Since the central
air-conditioner fan must be running continuously to allow the fresh air from the ERV to be
properly distributed throughout the house, it may pick up humidity from the cooling coil
when it is not operating and re-distribute it to the house, causing excess humidity. This
situation may be particularly aggravated if the air-conditioner is over-sized.

PRACTICAL TIPS

INSTALLING DUCTS TO / FROM INSIDE

• Building Codes and
Combustion Appliance
Installation Codes do
not allow location of
return air Grills or any
opening such as a
“breathing tee” in an
enclosed room with
spillage susceptible
combustion appliances.

• The fresh air inlet from
the ERV needs to
respect a minimum
distance from the furnace
return drop to ensure
proper air mixing and
temperature at the
furnace core.
See furnace manufacturer
for appropriate
specifications.

Direct Connection

• Should you wish to hard duct the supply air directly
into the air duct return of the furnace or air handler,
remember to check the airflow balance of the ERV with
the furnace fan both “on” and “off” to determine that
it does not imbalance the ERV more than 10%.

from ERV

For minimum distance
See local building codes
and practical tips.

To maximize airflow in the ductwork system, all ducts should be kept short and have as few bends or elbows as possible. Forty-five
degree are preferred to 90º elbows. Use “Y” tees instead of 90º elbows whenever possible.
All duct joints must be fastened with screws or duct sealant and wrapped with a quality duct tape to prevent leakage. Aluminum foil
duct tape is recommended. Galvanized ducting from the ERV to the living areas in the house is recommended whenever possible,
although flexible duct can be used in moderation when necessary.

SUPPLY AIR DUCTING

In homes without a forced air furnace, fresh air should be supplied to all habitable rooms including, bedrooms and living areas. It
should be supplied from high wall or ceiling locations. Grills that diffuse the air comfortably such as Fantech grille {MGE (metal) or
PGE (plastic)}s are recommended.To avoid possible noise transfer through the ductwork system, a short length (approximately 12”,
300 mm) of nonmetallic flexible insulated duct should be connected between the ERV and the supply/exhaust ductwork system.
The main supply and return lines to/from the ERV should be sized to matched the diameter of the port collar found on the ERV model
chosen. Branch lines to the individual rooms may be as small as 4 inches (100 mm), but 5 inch (125 mm) lines are preferred.If the
floor is the only option available, then special care should be taken in locating Grills. Areas such as under baseboard heaters will help
to temper the air.

21

• Choose the location for
your Supply and
Exhaust Grills - Fantech
MGE (metal) or PGE
(plastic). The Supply
Grills should be located
in every habitable room
and the Exhaust Grills
should be located in the
wet rooms.

• A piece of flexible
ducting should be
placed between the
Supply Air In and Out
collar of the ERV and
the rigid ducting to
absorb any noise or
vibrations.

• For proper network
of ducting, see TYPES OF

INSTALLATIONS.

• The Grills are to be
installed on the ceiling
or on the wall 6” (152
mm) to 12” (305 mm)
from the ceiling.

4 Push the Fantech grill - MGE (metal) or PGE (plastic) - into the optional

mounting collar or directly into installed elbow.

INSTALLING DUCTS TO / FROM INSIDE (CONT'D)

PRACTICAL TIPS

2 Working from a closet, attic or inside your joist wall, run the length of

ducting required for the proper grille location and cut a hole in the
drywall. Fasten the mounting collar (optional) to the ducting and fasten
the collar to the wall or ceiling with screws.

3 The Fantech grill - MGE (metal) or PGE (plastic) - airflow can be

adjusted by rotating the inside unit. It is recommended that the Grills be
completely opened at first and then adjusted later as needed.

Attic or Garage Installation

1 Begin with the duct collar marked “Exhaust Air In”. Slide a short piece

(12”) of flexible duct over the duct collar. Using duct tape, tape the
flexible duct to the collar. Run the flexible ducting to the main rigid duct
trunk line, which connects to the remainder of the ducts going to and
from rooms in the house. Repeat the steps for the “Supply Air Out” on the
side of the ERV.

Exhaust Air Ducting

The stale air exhaust system is used to draw air from the points in the house where the worst air quality problems occur. It is rec­ommended that return air ducts be installed in the bathroom, kitchen, and laundry room. The furnace or air handler return duct may
be also used to exhaust from. In this method, the exhaust air is not ducted back from bathrooms, kitchens, etc to the ERV with
“dedicated lines”.

It is the responsibility of the installer to ensure all ductwork is sized and installed as designed to ensure the system will perform as
intended. All air movement devices have a performance curve. The amount of air (CFM) that an ERV will deliver is directly related
to the total external static pressure (E.S.P.) of the system. Static pressure is a measure of resistance imposed on the blower by
length of duct work/number of fittings used in duct work, duct heater etc.

AIR FLOW BALANCING

CAUTION

• If the unit’s airflows are not properly balanced...

- The unit may not operate at it’s maximum efficiency.

- Energy recovery core damage may occur.

- The unit’s use could cause negative or positive pressure in your home causing cold air to enter or other combustible equipment
to backdraft.

- The unit may not defrost properly.

PITOT TUBE BALANCING PROCEDURE

* Pitot tube should be kept at
least 12” away from fans
elbows and dampers to ensure
accurate reading.

• The balancing procedure consists of measuring the exhaust air leaving the system and the supply air entering the system and ensuring that these

two are equal. A deviation of 10% or less is acceptable.

Place pitot tube a minimum of 18" from blower elbows.

Note: Duct connections may

vary, depending on model.

PITOT TUBE

BALANCING PROCEDURE

The following is a method of field balancing an ERV using a Pitot
tube, advantageous in situations when flow stations are not
installed in the ductwork. Procedure should be performed with
the ERV on high speed.

The first step is to operate all mechanical systems on high speed,
which have an influence on the ventilation system, i.e. the ERV
itself and the forced air furnace or air handler if applicable. This
will provide the maximum pressure that the ERV will need to
overcome, and allow for a more accurate balance of the unit.

Drill a small hole in the duct (about 3/16), three feet downstream
of any elbows or bends, and one foot upstream of any elbows or
bends. These are recommended distances but the actual instal­lation may limit the amount of straight duct.
The Pitot tube should be connected to a magnehelic gauge or
other manometer capable of reading from 0 to 0.25 in. (0-62 Pa)
of water, preferably to 3 digits of resolution. The tube coming out
of the top of the pitot is connected to the high pressure side of the
gauge. The tube coming out of the side of the pitot is connected
to the low pressure or reference side of the gauge.

Insert the Pitot tube into the duct; pointing the tip into the airflow.
For general balancing it is sufficient to move the pitot tube around
in the duct and take an average or typical reading. Repeat this
procedure in the other (supply or return) duct. Determine which
duct has the highest airflow (highest reading on the gauge).
Reduce this airflow using damper. The flows should now be bal­anced. Actual airflow can be determined from the gauge reading.

The value read on the gauge is called the velocity pressure.
The Pitot tube comes with a chart that will give the air flow
velocity based on the velocity pressure indicated by the gauge.
This velocity will be in either feet per minute or meters per sec­ond. To determine the actual airflow, the velocity is multiplied by
the cross sectional areas of the duct being measured.

This is an example for determining the airflow in a 6" duct.
The Pitot tube reading was 0.025 inches of water.
From the chart, this is 640 feet per minute.
The 6" diameter (D) duct has cross sectional area (A) of

A = 3.14 x (D/24) 2
A = 3.14 x (6/24) 2
A = 0.196 or about 0.2 ft

2

The airflow is then: 640 ft/min x 0.2 ft2 = 128 cfm

For your convenience, the cross sectional area of some com­mon round duct is listed below:

DUCT DIAM. (inches) CROSS SECTION AREA (sq ft.)

5 0.14
6 0.20
7 0.27
8 0.35

The accuracy of the airflow reading will be affected by how
close to any elbows or bends the readings are taken. Accuracy
can be increased by taking an average of multiple readings as
outlined in the literature supplied with the Pitot tube.

the duct and place the flow
measuring station between each
station. Make sure that the flow
measuring station’s air direction
arrow points in the direction of the
airflow. Secure the flow measuring
station with duct tape.

2 Before taking the reading, make

sure that the magnehelic gauge is
level and at 0. Refer to the flow
measuring station’s chart to
determine your unit’s airflow
velocity.
