SAFETY PRECAUTIONS FOR R32 REFRIGERANT

• The interior of unit should be maintained by HVAC techs only.

• 1. Information on servicing

• 1.1 Checks to the area

• Prior to beginning work on systems containing FLAMMABLE REFRIGERANTS, safety checks are necessary to ensure that the risk o f

ignition is minimised. For repair to the REFRIGERATING SYSTEM.

• 1.2 Work procedure

• Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being present w hile the

work is being performed.

• 1.3 General work area

• All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. W ork in confined

spaces shall be avoided.

• 1.4 Checking for presence of refrigerant

• The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of poten-

tially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all applica ble refriger-

ants, i. e. non-sparking, adequately sealed or intrinsically safe.

• 1.5 Presence of fire extinguisher

• If any hot work is to be conducted on the refrigerating equipment or any associated parts, appropriate fire extinguishing equip ment shall

be available to hand. Have a dry powder or CO

fire extinguisher adjacent to the charging area.

• 1.6 No ignition sources

• No person carrying out work in relation to a REFRIGERA TING SYSTEM which involves exposing any pipe work shall use any sources

of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, inc luding cigarette smoking,

should be kept suf ficiently far away from the site of installation, repairing, removing and disposal, during which refrigerant can possibly be

released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure tha t there

are no flammable hazards or ignition risks. “No Smoking” signs shall be displayed.

• 1.7 Ventilated area

• Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A

degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any release d

refrigerant and preferably expel it externally into the atmosphere.

• 1.8 Checks to the refrigerating equipment

• Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manu -

facturer’s maintenance and service guidelines shall be followed. If in doubt, consult the manufacturer’s technical department for assis-

tance.

• The following checks shall be applied to installations using FLAMMABLE REFRIGERANTS: the actual REFRIGERANT CHARGE is in

accordance with the room size within which the refrigerant containing parts are installed;

• the ventilation machinery and outlets are operating adequately and are not obstructed;

• if an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;

• marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;

• refrigerating pipe or components are installed in a position where they are unlikely to be exposed to any substance which may cor rode

refrigerant containing components, unless the components are constructed of materials which a re inherently resistant to being corroded or

are suitably protected against being so corroded.

• 1.9 Checks to electrical devices

• Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a faul t

exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault

cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be

reported to the owner of the equipment so all parties are advised. Initial safety checks shall include:

• that capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;

• that no live electrical components and wiring are exposed while charging, recovering or purging the system;

• that there is continuity of earth bonding.

• 2. Repairs to sealed components

• 2.1 During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to

any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a perma-

nently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.

• 2.2 Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in

such a way that the level of protection is affected. This shall include damage to cables, excessive number of connections, terminals not

made to original specification, damage to seals, incorrect fitting of glands, etc.

• Ensure that the apparatus is mounted securely.

• Ensure that seals or sealing materials have not degraded to the point that they no longer serve the purpose of preventing the ingress of

flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specifications.

• 3. Repair to intrinsically safe components

• Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible volt-

age and current permitted for the equipment in use.

• Intrinsically safe components are the only types that can be worked on while live in the presence of a flammable atmosphere. The test

apparatus shall be at the correct rating.

• Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmo-

sphere from a leak.

• NOTE: The use of silicon sealant can inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components

do not have to be isolated prior to working on them.

• 4. Cabling

• Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental

effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.

• 5. Detection of flammable refrigerants

• Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch

(or any other detector using a naked flame) shall not be used.

• The following leak detection methods are deemed acceptable for all refrigerant systems. Electronic leak detectors may be used to

detect refrigerant leaks but, in the case of FLAMMABLE REFRIGERANTS, the sensitivity may not be adequate, or may need re-calibra-

tion. (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is

suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated

to the refrigerant employed, and the appropriate percentage of gas (25 % maximum) is confirmed.

• Leak detection fluids are also suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as

the chlorine may react with the refrigerant and corrode the copper pipe-work NOTE Examples of leak detection fluids are

• bubble method,

• fluorescent method agents.

• If a leak is suspected, all naked flames shall be removed/extinguished.

• If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by

means of shut off valves) in a part of the system remote from the leak.

• 6. Removal and evacuation

• When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used. However,

for flammable refrigerants it is important that best practice be followed, since flammability is a consideration. The following procedure shall

be adhered to:

• safely remove refrigerant following local and national regulations;

• purge the circuit with inert gas;

• evacuate (optional for A2L);

• purge with inert gas (optional for A2L);

• open the circuit by cutting or brazing.

• The refrigerant charge shall be recovered into the correct recovery cylinders if venting is not allowed by local and national codes. For

appliances containing flammable refrigerants, the system shall be purged with oxygen-free nitrogen to render the appliance safe for flam-

mable refrigerants. This process might need to be repeated several times.

• Compressed air or oxygen shall not be used for purging refrigerant systems. For appliances containing flammable refrigerants, refriger-

ants purging shall be achieved by breaking the vacuum in the system with oxygen-free nitrogen and continuing to fill until the working

pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum (optional for A2L). This process shall be repeated

until no refrigerant is within the system (optional for A2L). When the final oxygen-free nitrogen charge is used, the system shall be vented

down to atmospheric pressure to enable work to take place. Ensure that the outlet for the vacuum pump is not close to any potential igni-

tion sources and that ventilation is available.

• 7. Charging procedures

• In addition to conventional charging procedures, the following requirements shall be followed.

• Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as

possible to minimise the amount of refrigerant contained in them.

• Cylinders shall be kept in an appropriate position according to the instructions.

• Ensure that the REFRIGERATING SYSTEM is earthed prior to charging the system with refrigerant.

• Label the system when charging is complete (if not already).

• Extreme care shall be taken not to overfill the REFRIGERATING SYSTEM.

• Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall be leak-tested on comple-

tion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.

• 8. Decommissioning

• Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It is

recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample

shall be taken in case analysis is required prior to re-use of recovered refrigerant. It is essential that electrical power is available before the

task is commenced.

• Become familiar with the equipment and its operation.

• Isolate system electrically.

• Before attempting the procedure, ensure that:

▪ mechanical handling equipment is available, if required, for handling refrigerant cylinders;

▪ all personal protective equipment is available and being used correctly;

▪ the recovery process is supervised at all times by a competent person;

▪ recovery equipment and cylinders conform to the appropriate standards.

• Pump down refrigerant system, if possible.

• If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.

• Make sure that cylinder is situated on the scales before recovery takes place.

• Start the recovery machine and operate in accordance with instructions.

• Do not overfill cylinders (no more than 80% volume liquid charge).

• Do not exceed the maximum working pressure of the cylinder, even temporarily.

• When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed

from site promptly and all isolation valves on the equipment are closed off.

• Recovered refrigerant shall not be charged into another REFRIGERATING SYSTEM unless it has been cleaned and checked.

• 9. Labelling

• Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed.

For appliances containing FLAMMABLE REFRIGERANTS, ensure that there are labels on the equipment stating the equipment contains

FLAMMABLE REFRIGERANT.

• 10. Recovery

• When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants

are removed safely.

• When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the

correct number of cylinders for holding the total system charge is available. All cylinders to be used are designated for the recovered

refrigerant and labelled for that refrigerant (i. e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pres-

sure-relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled

before recovery occurs. The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is

at hand and shall be suitable for the recovery of all appropriate refrigerants including, when applicable, FLAMMABLE REFRIGERANTS. In

• addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak-free

disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been

properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release.

Consult manufacturer if in doubt.

• The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant waste transfer

note arranged. Do not mix refrigerants in recovery units and especially not in cylinders.

• If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that

FLAMMABLE REFRIGERANT does not remain within the lubricant. The evacuation process shall be carried out prior to returning the

compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is

drained from a system, it shall be carried out safely.

5. The sites for installing and maintaining an air conditioner using Refrigerant R32 should be free from open fire or welding, smoking,

drying oven or any other heat source higher than 548℃ which easily produces open fire.

6.. When installing an air condition , it is necessary to take appropriate anti-static measures such as wear anti-static clothing and/or

Friedrich PTAC Digital Control and Unit Features

The new Friedrich digital PTAC has state of the art features to improve guest comfort, indoor air quality and conserve energy. Through the use of specifically

designed control software for the PTAC industry Friedrich has accomplished what other Manufacturer’s have only attempted – a quiet, dependable, affordable

and easy to use PTAC. Below is a list of features and their benifit to the owner.

ONLY TWO MODELS

BETTER

DEHUMIDIIFICATION

SOFT START

OPERATION

ERV 8 OUTDOOR AIR

FILTER

REMOTE THERMOSTAT

OPERATION

Some applications require the use of a wall-mounted thermostat. All new Friedrich PTACs may be

switched from unit control to remote thermostat control easily without the need to order a special model

or accessory kit.

INTERNAL DIAGNOSTIC

PROGRAM

The Friedrich digital PTAC features a self-diagnostic program that can alert maintenance to component

failures or operating problems. The internal diagnostic program saves properties valuable time when

diagnosing running problems.

ELECTRONIC

TEMPERATURE

LIMITING

By limiting the operating range, the property can save energy by eliminating “max cool” or “max heat” situ-

ations common with older uncontrolled systems. The new electronic control allows owners to set operat-

ing ranges for both heating and cooling independently of one another.

ROOM FREEZE

PROTECTION

When the PTAC senses that the indoor room temperature has fallen to 50

F, the unit will cycle on the

fan (high) and the electric strip heat to raise the room temperature to 55

F, and then cycle off again. This

feature works regardless of the mode selected and can be turned off.

CONDENSATE REMOVAL

SYSTEM

Condenser fan utilizes slinger ring technology to pick up condensate from the base pan and disperse it on

to the condenser coil where it evaporates. This helps to cool the coil and increase the energy efciency

of the unit.

DC INVERTER

FreshAire PTACs utilize a DC inverter rotary compressor to ensure part load efficiencies and reliable

operation.

UNIVERSAL ELECTRIC

HEATER

Unit has a universal power cord with 20 Amp coming standard out of the box.

All units are factory run tested to ensure trouble free operation.

FACTORY RUN-TEST

DIGITAL DEFROST

THERMOSTAT

The PV-Series uses a digital thermostat to accurately monitor the outdoor coil conditions to allow the heat

pump to run whenever conditions are correct. Running the PTAC in heat pump mode saves energy and

reduces operating costs. The digital thermostat allows maximization of heat pump run time.

INSTANT HEAT

HEAT PUMP MODE

Heat pump models will automatically run the electric heater to quickly bring the room up to temperature

when initially

energized, then return to heat pump mode. This ensures that the room is brought up to

temperature quickly without the usual delay associated with hea

t pump units

SEPARATE HEAT/COOL

FAN CYCLE CONTROL

The owner may choose between fan cycling or fan continuous mode based on property preference.

Fan continuous mode is used to keep constant airflow circulation in the room during all times the unit is ‘ON’.

Fan cycle will conserve energy by only operating the fan while the compressor or electric heater is operating.

The ability to set the fan cycling condition independently between heating and cooling mode will

increase user comfort by allowing the choice of only constantly circulating air in the summer or winter

time (unlike other PTAC brands that only allow one selection).

EMERGENCY

HEAT OVERRIDE

In the event of a compressor failure in heat pump mode, the compressor may be locked out to provide

heat through the resistance heater. This feature ensures that even in the unlikely event of a compressor

failure, the room temperature can be maintained until the compressor can be serviced.

CENTRAL DESK

CONTROL

READY(ONLY FOR UNIT

CONTROL)

All Friedrich digital PTACs have low voltage terminals ready

to connect a central desk control energy

management

system.

Controlling

the

unit

from

remote location like the front desk can reduce energy

usage and requires no additional accessories on the PTAC unit.

INDOOR COIL

FROST SENSOR

The frost sensor protects the compressor from damage in the event that airflow is reduced or low outdoor

temperatures cause the indoor coil to freeze. When the indoor coil reaches 33°F, the compressor is

disabled and the fan continues to operate based on demand. Once the coil temperature returns to 53°F,

the compressor returns to operation.

ULTRAQUIET

AIR SYSTEM

The PV-Series units feature an indoor fan system design that reduces sound levels without

lowering airflow or preventing proper air circulation.

HIGH EFFICIENCY

The Friedrich PTAC has been engineered so that all functional systems are optimized so that they work

together to deliver the highest possible performance.

DUAL MOTOR

The dual-motor design means that the indoor motor can run at slower speeds which reduces sound

levels indoors.

ROTARY COMPRESSOR

High efficiency rotary compressors are used on all Friedrich PTACs to maximize durability and effi-

ciency.

TOP-MOUNTED

AIR FILTERS

All Friedrich PTAC return air filters and PXFTB replacement filter kits are washable, reusable and

easily accessed from the top of the unit without the removal of the front cover.

FILTERED FRESH

AIR INTAKE

Friedrich PTAC units are capable of introducing up to 40 CFM of outside air into the conditioned space.

The outdoor air passes through a washable mesh screen to prevent debris from entering the airstream.

Outdoor coil endplates made from aluminium reduce corrosion on the outdoor coil common with

other coil designs.

R-32 REFRIGERANT

Friedrich PTAC units use environmentally-friendly refrigerant.

ALUMINIUM ENDPLATES

BREAK-PROOF

CONTROL DOOR

GALVANIZED ZINC

WALL SLEEVE AND

Emergency Heat Operation

FRP029

Pressing the “Cool” button after turn the unit on will put the unit into

cooling mode. Press “UP” or “DOWN” button to adjust the set point, the

unit will start the compressor and run appropriate frequency to maintain a

comfortable room temperature. The compressor will come on anytime that

the room temperature is 2℉above the set point. The fan will come on with

compressor.

Heating Mode

After turn on the unit, press the “Heat” button will put the unit into heating

mode.

Heat Pump Models (PVH)

When the “Heat” button is pressed initially the unit may call for electric

strips to bring the room to the set point. When the room temperature falls

2℉below the set point, the unit will turn on the compressor or electric

strip. The fan will run with compressor or electric strips. When the outdoor

ambient temperature falls below 32°F or outdoor coil temperature drops to

5℉, the unit will operate the electric strip instead of heat pump. During

heat pump mode, CPU detects the outdoor coil gets freeze, unit will go to

defrost. During the defrost operation (10min at most), there will be no

heating provide. After finishing defrost, electric heating will come on to

warm the room quickly.

In the event of a compressor failure in heat pump mode, the compressor

may be locked out to provide heat through the electric strip heater

automatically. This feature ensures that even in the unlikely event of a

compressor failure, the room temperature can be maintained until the

compressor can be serviced. If the unit still can’t run electric heater stably,

switch Dip switch 2 to OFF, it controls the emergency heat setting.

Constant Fan

Pressing the “Constant Fan” button will provide constant or cycle fan

operation in cooling or heating modes. The fan speed selection is

made by pressing either “High” or “Low” fan speed button.
