2.2 Main Components
2.2.1 Fan
The EC axial fan uses low-noise fan blades and a high-performance three-phase motor.
2.2.2 Heat Exchanger
The finned-tube heat exchanger provides high heat-dissipating efficiency and is convenient for maintenance.
2.2.3 Low Ambient Kit
The low ambient kit consists of a receiver with four heater belts, a head pressure valve, a safety valve, a check valve, and a
pressure switch. The kit is designed to maintain proper operating pressure in outdoor temperature down to -35 °C (-31 °F).
The low ambient kit is an optional component and is field-installed.

4 Outdoor environment 10 Head pressure valve
5 Indoor environment 11 Safety valve
6 Evaporator 12 Pressure switch
Receiver
The receiver stores refrigerant to help fulfill the needs for low temperature load in winter and high temperature load in
summer. There are three connection ports in the receiver to connect refrigerant inlet pipe, refrigerant outlet pipe, and safety
valve. Two sight glasses are also installed on the receiver to observe the refrigerant level in the receiver conveniently.

Vertiv™ Liebert® CRV CCD25 and CCD35 CondensersUser Manual

Head Pressure Valve
The head pressure valve is a three-way modulating valve that responds to discharge pressure. When the discharge pressure
falls below a certain value, the discharge port is opened and the discharge gas bypasses the condenser. When the discharge
pressure is high, the discharge port is closed and there is full liquid flow to the condenser.
During the soldering process, care must be taken not to overheat and damage the valve.
Figure 2.2 Structure Diagram of Head Pressure Valve
Item Description
1 Connected with discharge pipe
2 Connected with condenser
3 Connected with receiver
Heater Belt
The receiver is equipped with four heater belts which consume a total power of 300 Watts. The heater belt is controlled by
the pressure of refrigerant in the receiver. When the pressure is lower than 1.4 MPa (203.1 psig), the heater belt will start
heating. When the pressure is higher than 1.9 MPa (275.6 psig), the heater belt will stop heating.
Pressure Switch
Pressure switch controls the heater belt. When the refrigerant pressure in the receiver is lower than 1.4 MPa (203.1 psig), the
pressure switch will be closed and the heater belt will start working. When the refrigerant pressure in the receiver is higher
than 1.9 MPa (275.6 psig), the pressure switch will be opened and the heater belt will stop working.
Check Valve
Check valve is installed between the head pressure valve and the receiver on the liquid line, to prevent the refrigerant from
flowing back to the condenser. The arrow on the valve indicates the direction of the flow and it should point towards the
receiver.

3 Pre-installation Preparation
WARNING! Risk of improper moving. Can cause serious injury or death. Building and equipment damage may
also result. Use only lifting equipment that is rated for the unit weight by an OSHA-certified rating
organization. The center of gravity varies depending on the unit size and selected options. The slings must
be equally spaced on either side of the center of gravity.
CAUTION: Risk of contact with sharp edges, splinters, and exposed fasteners. Can cause injury. Only
properly trained and qualified personnel wearing appropriate, OSHA-approved PPE should attempt to move,
lift, or remove packaging from the unit in preparation for unit installation.
NOTICE
Risk of improper lifting. Can cause equipment damage. Make sure that the spreader bars are wider than the
unit. If the spreader bars are too short, the slings may crush the unit.
NOTICE
Risk of doorway/hallway interference. Can cause unit and/or structure damage. The unit may be too large to fit
through a doorway or hallway while on the skid. Measure the unit and passageway dimensions, and refer to the
installation plans prior to moving the unit to verify clearances.
NOTICE
Risk of improper storage. Keep the unit upright, indoors and protected from dampness, freezing temperatures
and contact damage.
Upon arrival of the unit and before unpacking:
•Verify that the labeled equipment matches the bill of lading.
•Carefully inspect all items for visible or concealed damage.
•Report damage immediately to the carrier and file a damage claim with a copy sent to Vertiv™ or to your sales
representative.
