WARNINGS

Only use on TXV systems using

either R410A or R22.

Ensure the system is powered

OFF before installing the Charg-

ing Jacket.

Severe injury can occur if the fan

turns ON before hooks are se-

curely fastened towards the top

of the condenser.

Wear eye protection.

Only use when the ambient dry

bulb temperature is between

37°F and 70°F (3°C to 21°C.)

Using outside of this range can

damage the air conditioner/heat

pump.

Head pressure of the system

needs to remain within the

following safe ranges to avoid

damage to the compressor or

other equipment:

R22:

55psig to 300psig

R410A: 97psig to 500psig

Stop the system if the head pres-

sure approaches these limits.

Description

HVACR technicians typically

cannot charge a cooling system in

cold weather. The cold temperature

removes too much heat from the

condenser coils.

The Charging Jacket from Fieldpiece

Instruments allow you to charge a TXV

system when ambient temperatures

are between 70°F and 37°F.

It works by restricting the fan outlet

of the condenser, in effect raising the

temperature within the condsenser.

This is a more effective method than

blocking the incoming air to the

condenser coil .

Look professional and increase

your amount of possible jobs. No

more trash bags or cardboard! Do it

the right way.

Maintenance

Hand wash with cold water and

mild detergent if needed and let air

dry. Do not machine wash or dry.

How to Use

The Winter Charge Setup may

only be used for equipment for which

the air conditioning manufacturers

approve the use of the Winter

Charge Setup. Refer to (California’s)

Energy Commissions website for

the list of split system air condition

units approved by the manufacturers

to use the Winter Charge Setup. In

addition to the requirements of this

document, manufacturers may issue

additional instructions/clarification

for the equipment and procedures to

be used to conduct the Winter Charge

Setup. These additional instruction/

clarifications are also available on

the (California) Energy Commission

website.

-- California Title 24 2013 Edition

Setup

1 Power down the system.

2 Install Charging Jacket:

A. Tighten Bungie Cinch around top

of condenser fan cage making sure

not to block the airflow inlet (sides.)

B. Fasten hooks securely so that the

the fan does not eject the Charging

Jacket when the system starts.

C. Always start with the top open,

then tighten the restriction string

to restrict airflow as needed.

3 Make sure people and animals are

clear of the condenser, then start

the system. If using on a heat pump,

set it to cooling mode.

4 Carefully adjust the restriction

of the Charging Jacket until the

difference between the high

side and the low side pressures

is between 160psi and 220psi

(R410A) or 100psi and 145psi (R22).

Restricting airflow increases the

pressure difference.

Check Refrigerant Charge

5 Once the system is within the

pressure difference range, allow

the system to stabilize for 15

minutes.

6 Calculate Actual Subcooling.

(

T

condenser, saturation

- T

liquid line)

If your subcooling is more

than three degrees less than the

target subcooling, then you are

undercharged. (continued)
