A licensed professional service technician (or eqUivalent)

should inspect the complete system each season (heating

and cooling). The following maintenance procedures

should only

be

conducted by a licensed professional ser-

vice technician (or eqUivalent).

Do

not

to service

the

unit

in

any

way.

AWARNING

ELECTRICAL SHOCK, FIRE.

OR

EXPLOSION HAZARD.

Annually (before heating season) inspect furnace venting

system, vent cap, heat exchanger, and burners for corro-

sion, deterioration, or deposits

of

debris. Remove any ob-

structions.

Inspect the furnace ror obvious signs

of

deterioration.

Inspect the furnace venting system

to

make sure it

is

in

place, physically sound, and without holes, corrosion. or

blockage.

Vent pipe must

be

clear and free of obstructions and must

slope upward away from the furnace.

Inspect the furnace return air duct connection to ensure

duct

is

sealed to the furnace and terminates outside the

space containing the furnace.

Inspect the physical support

of

the furnace to guarantee

that

It

is sound without sagging, cracks or gaps around

base and it maintains seal between base and support.

Inspect the condensate drain and trap

for

leaks

and

cracks.

The

dr~in

and

trap must also be cleaned and the trap must

be

filled with water.

During a seasonal check the service technician will

con~

duct a combustion analysis. The technician will also in-

spect the indoor blower, burner flames, electrical connec-

tions and the venting system.

TORQUE REQUIREMENTS

When servicing or repairing heating, ventilating, and air

USING MANIFOLD GAUGE SET

When checking

"the

system charge, only use a manifold

gauge set that features low loss anti-blow back fillings.

Manifold gauge set used with

HFC-410A

refrigerant

systems must

be

capable

of

handling the higher system

operating pressures. The gauges should be rated for use

With

pressures

of

0 - 800 psig on the high side and a

loW

side

of

3D"

vacuum

to

250

psig with dampened speed to

500

psi. Gauge hoses

must

be rated for use at up to

800

psig of pressure with a

4000

psig burst rating.

OPERATING

SERVICE

VALVES

The liquid and vapor line service valves are

lJsed

for

removing refrigerant, flushing, leak testing, evacuating,

checking charge and charging,

Each valve is equipped with a service port which has a

factory-installed valve stem. Figure 1 provides informatIon

on how

to

access and operating both angle and

ball

service

valves.

AND

LINE

SET

The

RFC1-metering

line

consisted

of

a

small

bore

copper

line

that

ran

from

condenser

to

evaporator

coil.

Refrigerant

was

metered

into

the

evaporator

by

ulilizing

temperature/pressure

evaporation

effects

on

refrigerant

In

the

small

RFC

line.

The

length

and

bore

of

the

RFC

line

corresponded

to

the

size

of

cooling

unit.

If

the

13ACX

is

being

used

with

either

a

new

or

existing

indoor

coil

Which

is

equipped

with

a

liquid

line

which

served

as

a

metering

device

(RFCI),

the

liquid

line

must

be

replaced

prior

to

the

installation

of

the

13ACX

unit.

Typically

a

liquid

line

used

to

meter

flow

is

1/4"

in

diameter

and

copper.

In

the

and

the

Indoor coil's

metering

device

(fixed

This

filter drier must

be

installed

to

ensure

a

clean,

moisture-free

Failure

to
