Residential Refrigeration and Front Venting Commercial Refrigeration Service Manual

2.0 Safety Information

Refrigerant HFC-134a

All self-contained models covered in this service manual are manufactured using refrigerant HFC134a.

Potential Problems with HFC-134a

HFC-134a compressors are manufactured with a synthetic based ester oil charge.

• The hygroscopic (water attraction) property of ester oil is many times greater than that of the mineral oils previously used with CFC-12.

• High system moisture causes the formation of acids and alcohol, which can damage the compressor.

• Systems or components of the refrigeration system should not be left open to atmosphere for more than (15) minutes at any time as humidity from the air will enter the system and be absorbed by the oil.

To ensure system dehydration:

• System should be evacuated to a level less than 250 microns

• Flux must not be used on any brazed joints.

Anytime a Perlick Refrigeration System is being serviced:

• It is recommended that the drier be changed

using the exact same style and size within the

system to avoid possible charge problems or contaminant issues.

Service Manual Safety Labels

PLEASE READ all instructions completely before attempting to service the unit. Take particular note of the DANGER, WARNING and CAUTION information in this manual. The information is important for the

safe and efcient service, operation and care of the

Perlick unit.

HAZARD!!

Indicates hazardous situation that will result in death or serious injury if not avoided.

• When isolated, shall not exceed 500 microns for a minimum of 10 minutes.

• Vacuum pump oil must never be allowed to enter the refrigeration system.

• No leak detection dyes are authorized for use

within any Perlick Refrigeration Products.

• Use of these materials will void complete sys tem warranty and place the burden on the service company for down-line service issues.

Cleanliness of the system is extremely important.

• The presence of residue (Chlorinated or greasy residues, mineral oil, or impurities) can lead to capillary tube restrictions, oil return prob lems and compressor damage.

• A nitrogen purge should be utilized when brazing.

Indicates hazardous situation that may result in death or serious injury if not avoided.

Caution indicates hazardous situation that could result in minor or moderate injury and property damage.

Caution without symbol indicates unsafe practice

situation that could result in property damage only.

4.0 Variable Speed Compressor Specication

Never connect compressor directly to AC power!

Always use specied inverter when testing

compressor!

• The compressors employed within many of Perlick’s cabinets are on the cutting edge of technology for reciprocating hermetic compressors. The compressors are variable speed models developed and man

ufactured by Embraco. Depending on the model of the cabinet, either a VEMY3H, VEMY6H or VEGY7H

will be found powering the refrigeration system. The compressor itself looks like a standard fractional horsepower hermetic reciprocating compressor. The electrical, overload, relay and capacitor, which are normally found connected to the compressor pins has been replaced by an electronic box which is called the inverter.

• The inverter is an electronic board, which controls the compressor and has to have power to it at all times for it to function properly. It controls the starting of the compressor and the speed at which it is

running at from 1600 rpm to 4500 rpm. A normal hermetic reciprocating compressor runs at a con stant 3600 rpm. The Digital Temperature Control controls a separate power circuit used as the power

to the inverter driver circuit, which turns the compressor on and off.

• The inverter is powered by 115-127V 50-60Hz 1 Ph AC. The inverter driver circuit power is also 115- 127V 50-60Hz 1Ph AC power. The inverter converts this to 230V 53-150Hz 3 Ph power to drive the

compressor. The resistance between any combination of the three compressor pins for the HP24”

Series is 16.07 ohms, and the HP48 & HP72” series is 6.4 ohms. The inverter has a plastic 3-pin recep

tacle which gets plugged onto the compressor pins (can only be installed one way for proper orientation). The inverter also comes with a ground wire, which gets plugged onto the compressor ground lug. The inverter is then mounted to the compressor fence by sliding it down and tipping to the vertical position. A single fastener is then used to mount it to the fence (do not over tighten as it is fastening into the plastic inverter housing).

Refrigeration System Repair Instructions Page 4-1

Residential Refrigeration and Front Venting Commercial Refrigeration Service Manual

5.0 Compressor Inverter Operation

• Upon initial power to the inverter, the electronic board is checked for problems or malfunctioning

components. If a problem is detected, the inverter will not allow power to the compressor and will

wait 8 minutes until it will repeat the process to see if it has been corrected.

• If the inverter power circuit is interrupted or reduced to a level below operation level, the inverter will

not allow continued operation of the power circuit to the compressor.

Compressor Start-Up

• Upon the temperature control calling for cooling, the inverter will wait 1-3 seconds before applying

current to the compressor motor for the rst time. In case of any abnormality in trying to start the

compressor (unequal pressures, locked rotor condition or open winding, etc.), the inverter will wait

6 seconds before establishing a new start-up trial.

• The maximum number of start-up trials is 12. If the compressor does not start after 12 trials, a

start-up error is set, and the system will wait for 8 minutes to repeat the starting procedure.

• During start-up of the compressor, the current is limited in accordance with the type of motor

connected to the inverter. The compressor always starts in its minimum rpm condition (1600 rpm)

to conserve energy and alleviate noise associated with a standard compressor start-up.

• During initial power being applied to the refrigerated cabinet, the compressor will always start in its

minimum rpm condition (1600 rpm) and remain at this speed for 7 minutes. After this time has

passed the program will move the compressor to its maximum rpm level until the initial controller cut-out temperature has been achieved.

Normal Operation

During running condition, the speed is measured each shaft turn and the result is compared with the desired speed. If the actual speed is lower than desired, the inverter will increase the power applied to the motor, which in turn will increase the shaft speed until the equilibrium is achieved. The opposite can happen likewise, in that if the actual speed is higher than the desired speed, the inverter will decrease the power applied to the motor, which in turn will decrease the shaft speed until the equilibrium is achieved.

The compressor will generally run at its slowest speed (1600 rpm) during normal cycling conditions with

out added load to the cabinet or door openings. This is done to conserve energy and reduce noise. A typical refrigeration system is designed for high load, high ambient conditions, meaning the compressor is

typically oversized for normal daily operation. It has been shown in residential equipment that a refriger ator or freezer or combination of the two with standard reciprocating compressor is typically designed for

conditions it sees less than 25% of the time (high load/high ambient). While employing the variable speed

compressor the equipment has been designed for the conditions it sees 75% of the time while still having

the capacity to cover the conditions it sees 25% of the time.

Troubleshooting Guide – Beverage Dispensing Page 5-1

Residential Refrigeration and Front Venting Commercial Refrigeration Service Manual

6.0 Troubleshooting Compressor Inverter

• Ensure the inverter has 120V applied to the two pin connector on the inverter. If no power,

check where power is interrupted.

• If temperature control is calling for cooling, check inverter signal circuit for 120V, typically the red lead. If no power, check where power is interrupted. If there is power, disconnect power to the entire unit and wait 5 minutes to ensure internal system pressures are

equalized. Plug in unit and feel top of compressor to see if it is trying to start (see in-

formation from section Compressor Start-Up above). If compressor is trying to start, but unable to, the system could have a restriction, the inverter may not be applying the correct power to the compressor pins (check pins to see if getting 120V to each pin).

• Resistance between all pins should be the same. Dependent upon temperature of the com-

pressor, resistance could be different than the resistance specied at the standard temperature.

Air Inltration

Air inltration can occur in several locations.

Note: Unit may manifest longer than normal run

times caused by the additional loads that

air inltration presents.

Signs of air inltration include:

• Presence of water, moisture or ice

• Condensation on glass or metal surfaces

STEP 1. Door Gaskets

• Check door gaskets for rips, cracks, or oth er damage.

• The door gasket should be pushed in rmly and lay at.

• Ensure gasket forms a complete seal around door.

STEP 2. Sealing Compound

• Sealing compound is used to seal wiring and line set pass-through between the con denser and the evaporator compartments.

See Figure 7-1 and Figure 7-2.

• Check for voids and ensure sealing

compound completely lls the space.

Note: Drain tube should be routed through metal bracket and end of tube should be retained by metal

insert to create a trap. This trap should be lled with

water to prevent air from moving through the tube and into the cabinet. Sometimes, gurgling sounds will be heard upon the door closing as the internal cabinet pressure changes requiring air to be pushed out which happens through the drain tube trap.

Air Flow Obstructions

The unit must have free air ow to front grille to

operate properly.

Restricted air ow results in high head pressures and reduction in efciency due to longer run times.

Proper air ow through condenser and evaporator is necessary for efcient operation.

• Never obstruct air ow in and out of the

machine compartment.

• The front grille must be free from obstructions, dust, and debris.

• Never obstruct air ow to Evaporator Fan.

• Make sure higher temperature ambient air from

another unit is not directed to condenser coil (i.e. another heat source directly across from the unit).

Clean Condenser Coil

ELECTROCUTION HAZARD!! Never attempt to repair or perform maintenance on the unit until the Main electrical power has been dis connected.

Perlick’s warranty does not cover cleaning of con denser.

The condenser is located directly behind the front

grille. See Figure 7-11 through Figure 7-13.

Figure 7-13. Clean Condenser Coils

Condenser coils that are covered with dust and de-

bris restrict air ow. This results in high head pressures and lower efciency due to longer run times.

Use soft brush and vacuum to clean coil every 90 days, or more often if conditions require.

Ambient Temperature

High ambient temperature and high humidity conditions may result in performance issues and/or refrigeration system failure.

The unit must be protected from precipitation.

Do not subject to direct solar load.

Under extreme temperature and/or relative humidity conditions the front face, gasket and/or glass door may show signs of condensation. When temperature and/or relative humidity conditions return to normal condensation will disappear.

• Placing a system that has lost refrigerant

under a vacuum without rst repairing the

leak will draw contaminants into the system through the point of leak. Find source of the leak and correct it!

• The use of an electronic leak detector is highly encouraged.

• If the entire charge has leaked out of the unit,

the sealed system should be pressurized with

Beverage Dispensing

Perfectly poured draught beer is the result of proper temperature, gas pressure, mixture, and a well-maintained draught beer system. It’s easy to take all the variables for granted when beer is pouring well. But improperly pouring beer can be very frustrating, and can result in loss of sales- This chapter is intended to provide useful troubleshooting steps anyone can follow to solve draught beer dispense problems.

The single most common cause of problems encountered in draught beer dispense systems

is temperature control. The rst step in solving any dispensing problem is to conrm that the

temperature of the keg and the cooler are where they are supposed to be. In air-cooled and glycol-cooled systems, the next step is to check the temperature of the beer being delivered to

the faucet, conrming that the air and glycol

systems

used to maintain proper beer line temperature are working properly.

The troubleshooting steps that follow are

organized by the type of draught beer system and

how the systems are cooled, using air. Direct-draw systems cooled by air or glycol each have unique features that are addressed in the troubleshooting steps

Other steps including gas pressure and supply, beer supply, and mechanical issues are also discussed.

• It’s important to remember that carbonation is proportional to absolute pressure, not gauge pres sure. Atmospheric pressure drops as elevation goes up. Therefore, the gauge pressure needed to achieve proper carbonation at elevations above sea level must be increased. Add 1 psi for every 2,000 feet above sea level.

NOTE:

Offset is the difference between the temperature that is actually being sensed and what is displayed to ensure proper product temperatures.

Example: Set point 34, Offset +6, controller needs to sense 28F before the unit will turn off.

Delay: Control has a programmed time delay on temperature rise to show a stabilized temperature within the

refrigerated space.

Example: Set point 34F, unit cycles off, consumer opens the door, rather than have the temperature immediately shoot-up, it is delayed and will continue to show 34F until the delay time elapses. Meanwhile the controller is sensing actual temperature and will turn on when it senses set point plus hysteresis.

8.10 Mullion Heater Hook-Up

STEP 1.

The rear panel and the front bottom toe kick grill need to be removed. If the unit is installed, then it needs to be pulled out. The mullion heater ohms out around 1500 ohms. When connected, it draws very

low amps, around .08.

Remove the rear panel and locate the 3 plugs on the

right side ceiling. All plugs should be secured rmly

to the ceiling. The third plug back (closest to the condenser fan motor) is for the mullion heater. The red female push on connectors are not hooked up. It

could be bundled with a zip tie; if so, cut the zip tie

and straighten the wires out.

STEP 3.

The wires can be pushed over the compressor from the front or pulled from the rear by locating the white wire coming off the compressor.

Mullion Heater Plug

STEP 2.

The white mullion heater wire with the red female push on connector will connect to a blue male push on connector that has a white cap. The blue connector will have two white wires connected to it.

You should be able to see the blue connector through the front with the toe kick grill removed. One of the white wires is coming from the compressor electricals.

STEP 4.

The black mullion heater wire with the red female push connector will connect to a red male push on connector that has a white cap. It is also a black wire.

This male connector can be a little tricky to locate. It should be tucked behind the compressor towards the

front and behind the white DC Inverter mounted to the oor. It might be easier to push this wire to the

rear from the front.
