Service Pipe Connection/Disconnection Method

1. Preparation before attachment of the service piping

1) Turn the stem of the high pressure and low pressure service valves (2 places) to open it

toward the back seated position.

2) Attach a packing to the service piping (2 places)

Note: 1. Use a new packing.

2. Check that there is no adhering foreign objects.

2. Service piping attachment

1) Remove the nut and packing included with the service valve (2 places).

2) Assemble the service piping.

First, turn the nut by hand until the packing needs to be fastened with a tool.

If it is difficult to fasten, loosen it slightly and try to make the nut parallel with the male thread

of the service valve, and then fasten it gradually.

Note: Fastening the nut with a tool while the threads are not fully aligned would break

the thread and lead to a gas leak.

3. Fastening the service piping

Fasten the nuts by hand up to the condition shown below, and then fasten them with a tool.

Fastening torque of 13 1N・m is recommended for the nuts.

Note: Fastening it too tight may deform the packing.

4. After completing service operation

1) After completing service operations such as the evacuation and refrigerant charging, turn

the stem of the service valve to open it toward the back seated position.

(Check that the access ports of the high pressure and low pressure service valves have

been closed.)

2) Any remaining nitrogen or refrigerant in the service piping should be purged.

3) Detach the service piping.

After detaching the service piping, Install the nut originally used on the service valve by hand.

(Refer to "2. Service piping attachment”.)

4) Fasten the nut by using a tool. Fastening torque of 13 1N・m is recommended.

(Refer to "3. Fastening the service piping”.)

5) Check Gland nut loosening of the low pressure and high pressure service valves and fasten

them if any looseness exists. Fastening torque is 10 2 N・m.

Evacuation Mode

1. Evacuation mode

In the evacuation mode, fully open the electronic expansion valve and solenoid valve in the

refrigeration unit.

If the refrigeration unit is not set to the evacuation mode, the electronic expansion valve and

solenoid valve in the refrigeration unit do not open, thus leading to incomplete the evacuation.

2. Evacuation mode procedure

1) Turn OFF the power circuit breaker. (The evacuation mode cannot be started with power

supplied to the refrigeration unit.)

2) On the control PCB, turn switch No.1 of the 8P DIP switch ON (SW13).

3) Turn ON the operation switch (Seesaw switch S1).

4) Turn slide switch SW15 on the control PCB to [Check] .

5) Turn ON the power circuit breaker. (Supply power to the refrigeration unit.)

6) The 7-segment LED display indicates [uAcU].

Refrigerant Releasing Procedure

1. Service piping attachment

1) Check that the access ports of the high pressure and low pressure service valves have been

closed. (The back seated position)

2) Attach the service piping with the joint valve in "Closed" condition.

3) Fasten the nuts by hand up to the condition shown below, and then fasten them with a tool.

Fastening torque of 13 1N・m is recommended for the nuts.

Note: Fastening it too tight may deform the packing.

2. Refrigerant releasing

1) Set the evacuation mode.

2) Set the low pressure and high pressure service valves to the Mid-position. (The access ports

are open.)

3) Slowly open the joint valve to release refrigerant.

Caution The rapid release of refrigerant could cause refrigerant oil to be

released together with refrigerant.

Airtight Test Procedure

(Execute this test after competing piping work and airtight test but before starting

heat insulation work)

1. Piping connection

1) Connect the joint valve of the service piping (SPK-TU125) and the manifold gauge set

exclusively for CO2refrigerant by using a CO2charge hose or 1/4" pipe.

2) Connect a nitrogen cylinder and the manifold gauge set by using a CO2 charge hose or

1/4" pipe.

2. Airtight test

1) Set the evacuation mode in accordance with " Evacuation Mode".

2) When carrying out an airtight test of interconnecting piping and load-side equipment

(such as showcase and unit cooler), set up the service valves with the front seat.

After replacing components of the refrigeration unit and when performing an airtight test of

the refrigeration unit, use the Mid-position. (The access ports are open.)

However, at this time, avoid applying the high-pressure side airtight test pressure to

the low-pressure side.

Note: Airtight test of the refrigeration unit was completed at the time of factory

shipment. Pressure testing should only be carried out by personal / companies

who have necessary certification. Consider carefully local regulations and

EN378.

Design pressure in Factory

Caution Make sure to close the vacuum valve of CO2manifold gauge set.

Consider special local regulations and consider Installation of all

equipment have to be in accordance to pressure directive 2014/68/EU

and European norm EN378.

Vacuum Pump Attachment and Evacuation Procedure

1. Piping connection

1) Connect the joint valve of the service piping (SPK-TU125) and the manifold gauge set

exclusively for CO2refrigerant by using a CO2charge hose or 1/4" pipe.

2) Connect a vacuum pump and the manifold gauge set by using a charge hose or 1/4" pipe.

The low side gauge for this operation should be able to indicate the vacuum level to be

reached (-0.1 MPa).

2. Evacuation

1) Set the evacuation mode in accordance with “Evacuation Mode".

2) Set the low pressure and high pressure service valves to the Mid-position, the access ports

are open, and operate the vacuum pump.

3) Continue the evacuation until the vacuum gauge indication reaches -0.1MPa and continue

evacuation for an additional 1 to 3 hours.

Caution Evacuation should be performed after completing the airtight test.

Please follow local regulations and EN378.

Caution When the intended vacuum level (-0.1MPa) cannot be reached

after 2 hours, check the set up for any leaks.
