Note, these instructions are in addition to the safety rules that apply in the country where the dryer is installed. Before packing for shipment each HHPR series refrigerated air dryer undergoes a rigorous test to ensure the absence of any manufacturing faults and to demonstrate that the device can perform all the functions for which it has been designed.

Identification plate Identification plate The identification plate is located on the back of the dryer and shows all the primary data of the machine. This data should always be referred to when calling the manufacturer or distributor. The removal or alteration of the identification plate will void the warranty rights.
Safety rules Safety rules Definition of the conventional signs used in this manual Carefully read instruction manual before attempting any service or maintenance procedures on the dryer. Caution warning sign. Risk of danger or possibility of damage to equipment, if related text is not followed properly.
Safety rules Warnings Compressed air is a highly hazardous energy source. Never work on the dryer with pressure in the system. Never point the compressed air or the condensate drain outlet hoses towards anybody. The user is responsible for the proper installation of the dryer. Failure to follow instructions given in the “Installation”...
Installation Instructions for the use of pressure equipment To ensure the safe operation of pressure equipment, the user must conform strictly to the above directive and the following: 1. The equipment must only be operated within the temperature and pressure limits stated on the manufacturer’s data nameplate.
Installation Installation site Failure to install dryer in the proper ambient conditions will affect the dryer’s ability to condense refrigerant gas. This can cause higher loads on the compressor, loss of dryer efficiency and performance, overheated condenser fan motors, electrical component failure and dryer failure due to the following: compressor loss, fan motor failure and electrical component failure.
Installation Installation layout 1 Air compressor 2 Aftercooler 3 Condensate separator 4 Pre-Filter (min. 5 micron) 5 By-pass group 6 Dryer 7 Compressed air tank 8 Final filter 9 Condensate drain In case of heavily polluted inlet air (ISO 8573.1 class 3.-.3 or worse quality), we recommend the additional installation of a pre-filter (5 micron minimum) to prevent a clogging of the heat exchanger.
Installation Connection to the compressed air system Operations to be performed by qualified personnel only. Never work on system under pressure. The user is responsible to ensure that the dryer will never be operated with pressure exceeding the maximum pressure rating on the unit data tag. Over-pressurizing the dryer could be dangerous for both the operator and the unit.
Installation Electrical connections Qualified personnel should carry out connecting unit to the main power. Be sure to check the local codes in your area. Before connecting the unit to the electrical supply, verify the data nameplate for the proper electrical information.
Start-up Start-up Preliminary operation Verify that the operating parameters match with the nominal values stated on the data nameplate of the dryer (voltage, frequency, air pressure, air temperature, ambient temperature, etc.). This dryer has been thoroughly tested, packaged and inspected prior to shipment. Nevertheless, the unit could be damaged during transportation, check the integrity of the dryer during first start-up and monitor operation during the first hours of operation.
Start-up Start-up and shut down Start-up (refer to paragraph 7.1 Control Panel) Check the condenser for cleanliness. Turn ON the switch - pos. 1 on the control panel. Ensure that electronic controller is ON. Wait a few minutes; verify that the dew point temperature displayed on electronic controller is correct and that the condensate is regularly drained.
Technical description Technical description Control panel The control panel illustrated below is the only dryer-operator interface. HHPR115A, HHPR150A HHPR200A 1 ON-OFF switch 2 Electronic controller 3 Air and refrigerant flow diagram Operation Operating principle - The dryer models described in this manual operate all on the same principle. The hot moisture laden air enters an air to air heat exchanger.
Technical description Refrigerant compressor The refrigerant compressor is the pump in the system, gas coming from the evaporator (low pressure side) is compressed up to the condensation pressure (high pressure side). The compressors utilized are manufactured by leading manufacturers and are designed for applications where high compression ratios and wide temperature changes are present.
Technical description Capillary tube It consists of a piece of reduced cross section copper tubing located between the condenser and the evaporator, acting as a metering device to reduce the pressure of the refrigerant. Reduction of pressure is a design function to achieve optimum temperature reached within the evaporator: the smaller the capillary tube outlet pressure, the lower the evaporation temperature.
Technical description 7.12 Refrigerant pressure switches LPS – HPS As operation safety and protection of the dryer a series of pressure switches are installed in the gas circuit. LPS : Low-pressure protection device on the suction side of the compressor, trips if the pressure drops below the pre-set value.
Technical description 7.14 Electronic controller DMC34 Led - Temperature in °C Led - Temperature in °F Led – Drain ON Led – Fan ON Led – Alarm/Service Button – Setup menu access / Condensing Button – Decrease / Service Button – Increase / Drain test The DMC34 displays dew point temperature, controls the condenser fan activation, displays a service reminder and keeps record of the total hours of operation of the dryer.
Technical description 7.14.4 How a service warning / alarm is displayed A service warning / alarm is an unusual event that requires the attention of the operators/maintenance technicians. It does not stop the dryer. When a service warning / alarm is active, the led is lighted or flashing.
Technical description 7.14.9 How to change the operating parameters The setup menu can be used to change the dryer’s operating parameters. Only qualified personnel must be allowed to access to the setup menu. The manufacturer is not responsible for malfunctioning or failure due to modification to the operating parameters.

Maintenance, troubleshooting, spare parts and dismantling Spare parts Spare parts list is printed on a dedicated sticker applied inside the dryer. On this sticker each spare part is identified with its ID Number and related Spare Part Number. Here below the cross reference table between ID Numbers and exploded drawings Ref.
Maintenance, troubleshooting, spare parts and dismantling Maintenance operation on the refrigeration circuit Maintenance and service on refrigerant systems must be carried out only by qualified refrigeration technicians only, according to local rules. All the refrigerant of the system must be recovered for recycling, reclamation or destruction. Do not dispose the refrigerant fluid in the environment.
