NOTE:

When

coil

is

used

in

a

heat

pump

application

with

electric heat,

coil

must

be

installed

upstream

of

the

electric

heater

(refer

to

Figure

This

prevents

electric

heat

from

driving

up

refrigeration

system

pressure

during

NOTE:

When

coil

is

installed

to

a

gas

or

oil

furnace,

coil

must

be

installed

downstream

of

the

furnace

heat

exchanger

(refer

to

Figure

This

reduces

condensate

formation

in

the

furnace

heat

during

When

the

furnace

is

in

application

on

must

be

installed

between

When

CONDENSATE

DRAIN

Coil

is

provided

with

two

%”

NPT

condensate

drain

connections.

(EDM

models

have

two

connections

for

upflow/downflow,

and

two

more

connections

for

horizontal.)

The

connection

with

the

larger

internal

opening

is

the

primary

drain,

and

the

connection

with

the

smaller

internal

opening

is

the

secondary

(overflow)

drain.

Condensate

drain

lines

should

be

installed

in

a

manner

that

does

not

obstruct

access

to

the

filter.

Use

PVC

fittings

on

the plastic

condensate

pan.

Finger

tighten

plus

114

turns.

Do

not

over-tighten.

Use

pipe

dope.

If

coil

is

located

in

or

above

a

living

space

where

damage

may

result

from

condensate

overflow,

a

separate

4” drain

must

be

provided

from

secondary

(overflow)

drain

connection.

Run

this

drain

to

a

place

in

compliance

with

local

installation

codes

where

it

will

be

noticed

when

unitis

operational.

Condensate

flowing

from

secondary

(overflow)

drain

indicates

a

plugged

primary

drain

-

unit

requires

service

or

water

damage

will

occur.

NOTE:

For

downflow

electric

furnace,

the

secondary

(overflow)

drain

connection

must

be

installed

to

prevent

possibility

of

water

dripping

onto

live

electrical

components.

1.

Connect

drain

lines

to

the

appropriate

drain

connections.

Drain

lines

should

not

be

smaller

than

the

drain

connections

(&’).

2.

NOTE:

Traps

must

be

used

when

the

coil

is

installed

on

the

return

air

side

of

the

system.

When

coil

is

installed

on

the

supply

side

(outlet

air)

it

is

not

necessary

to

install

traps

and

better

drainage

is

usually

achieved

without

traps.

Install

properly

sized

condensate

traps

in

the

drain

line

as

close

to

the

coil

as

possible.

Install

drain

lines

below

the

bottom

of

the

drain

pan and

pitch

the

drain

lines

down

from

the

coil

at

least

%

inch

per

foot

of

run.

Horizontal

runs

over

15

feet

long

must

also

have

an

anti-siphon

air

vent

(stand

pipe),

installed

ahead

of

the

horizontal

run.

An

extremely

long

horizontal

run

may

require

an

oversized

drain

line

to

eliminate

air

trapping.

Refer

to

Figure

5

for

minimum

trap

dimensions.

Route

to

the

outside

or to

a

floor

drain.

Check

local

codes

before

connecting

to

a

waste

(sewer)

line.

Prime

all

traps,

test

for

leaks,

and

insulate

drain

lines

where

sweating

could

cause

water

damage.

If

a

gravity

drain

cannot

be

used,

install

a

condensate

pump.

Install

the

pump

as

close

to

the

indoor

section

as

possible.

WARNING

ELECTRICAL

SHOCK

HAZARD

Failure

to

shut

of

electric

power

could

result

in

personal

injury

or

death.

Before

adjusting

blower

speed,

shut

off

electric

power

to

the

furnace

or

blower

module.

It

is

important

that

the

correct

amount

of

air

(CFM)

flows

through

the

coil.

The

installer

must

determine

the

required

CFM

based

on

the

characteristics

of

the

specific

system

(such

as

system

size,

ducting,

components,

and

accessories).

In

general,

400

CFM

per

ton

is

the

nominal

required

value,

with

a

range

of

350

-

450

CFM

per

ton.

Check

Static

Pressure

Drop

and

CFM

Across

Coil

The

amount

of

air

(CFM)

is

related

to

a

pressure

drop.

To

determine

the

CFM,

measure

the

pressure

drop

using

an

inclined

manometer

(sometimes

called

draft

gauge

or

air

flow

gauge).

1.

The

coil

should

be dry
