Frequently Asked Questions - SRCOOLLONGPKIT Tripp Lite

What is the function of this piping extension kit?

This kit prevents a large amount of liquid refrigerant from entering the compressor when it is stopped, thus avoiding liquid slugging at startup.

When should this kit be installed?

When the equivalent length of the one-way refrigerant piping exceeds 30 m (98 ft).

What components are included in the SRCOOLLONGPKIT kit?

The kit includes a solenoid valve, a solenoid coil, and a check valve.

Where to install the solenoid valve and check valve?

The solenoid valve is installed on the liquid line between the indoor and outdoor unit, within 5 m (16 ft) of the indoor unit. The check valve is installed on the gas line, closer to the outdoor unit.

How to wire the solenoid coil?

Connect the coil power supply to the indoor unit connection box on the terminals labeled solenoid valve power for extension pipe (L1 and L2). The ground cable connects to the left ground terminal (PE).

Is additional refrigerant required with this kit?

Yes, if the connecting piping between the cooler and condenser exceeds 10 m (33 ft). Use the formula given in the manual: additional amount (lb) = length ratio × liquid line length (ft).

Which lubricating oil to add and in what quantity?

Add synthetic oil RL68H (or equivalent) according to the formula L = (R × 0.25/0.9) × 1000 ml, where R is the additional refrigerant charge (kg). The maximum quantity is 4 liters.

Is this kit compatible with all Tripp Lite row cooler models?

This kit is designed for row coolers of the SRCOOLDXRW series.

What liquid line diameters are supported?

Supported diameters are: 3/8, 1/2, 5/8, 3/4, and 7/8 inch.

Are there safety precautions to follow during installation?

Follow the manual instructions: discharge the circuit before intervention, use appropriate tools, and ensure tightness of connections. Non-compliance may damage the compressor.

Extension Pipe Kit for SRCOOLDXRW In-Row Cooling Units

Model: SRCOOLLONGPKIT

When the equivalent length of the one-way pipeline on the refrigerant side exceeds 98 ft. (30 m), an extension pipe kit is required. This extension pipe kit prevents a large amount of liquid refrigerant from entering the compressor when the compressor is stopped, while also avoiding compressor liquid shock during the next startup.

1. Install Valve

The extension pipe kit includes a solenoid valve, valve coil and check valve.

Coil and Valve Before and After Assembly

• Install the solenoid valve with the coil to the liquid pipe between the indoor unit and outdoor unit. The distance to the indoor unit should be as short as possible, no more than 16 ft. (5 m).
• Install the check valve at the gas pipe between indoor unit and outdoor unit (nearest to the outdoor unit).
• The coil cable connects to indoor unit.

2. Solenoid Valve Coil Wiring

25kW Unit Connection Box
12kW Unit Connection Box

Connect coil power to the indoor unit connection box, labeled Solenoid Power for Extension Pipe (L1 and L2). The ground cable connects to the left grounding terminal (PE).

3. Refrigerant and Oil Charge

When the connecting piping between the In-Row Cooling Unit and the condenser exceeds 33 ft. (10 m), add more refrigerant. Use RL68H (or of the same viscosity) synthetic oil. Calculate the additional amount according to the following formula:

Additional amount (lb.) = Length ratio () x Liquid line length (ft.)

Liquid pipe diameter (in.) Length ratio (lb./ft.)
3/8 0.039
1/2 0.075
5/8 0.122
3/4 0.145
7/8 0.243

$$ R (k g) = \frac {A d d i t i o n a l a m o u n t (I b .)}{2 . 2} $$

When the length of the connecting piping exceeds 33 ft. (10 m), add lubricating oil using the following formula:

$$ \mathrm {L} = \frac {\mathrm {R} \times 0 . 2 5}{0 . 9} \times 1 0 0 0 $$

L: Amount of lubricating oil to add (ml)

R: Additional refrigerant charge (kg)

Note: Maximum additional oil is 4L. If calculation is over 4L, do not exceed 4L.
