 The condensing unit must only be used for 

its designed purpose(s) and within its scope of 

application. 

 Under all circumstances, the EN378 (or  

other applicable local safety regulation) 

requirements must be fulfilled.
The condensing unit is delivered under nitro-

gen gas pressure (1 bar) and hence it cannot 

be connected as it is; refer to the «installation» 

section for further details. 
The condensing unit must be handled with cau-

tion in the vertical position (maximum offset 

from the vertical : 15°)

1 – Introduction

These instructions pertain to Optyma™ High 

Ambient 52 Pack condensing units OP-LPHE/

MPZE (R404A, R134a) used for refrigeration sys-

tems. They provide necessary information regar-

ding safety and proper usage of this product.

The condensing unit includes following:

  •  Reciprocating  compressor

 •  Microchannel heat exchanger

 •  Dual pressure switches

 •  Service valves suction/liquid

 •  Weather proof housing

  •  Filter  drier

 •  Receiver with stop valve

  •  Sight  glass

  •  Solenoid  valve

 •  Oil separator (LBP only)

 •  Discharge thermostat (LBP Only)

2 – Handling and storage

 •  It is recommended not to open the packaging 

before the unit is at the final place for installation.

 •  Handle the unit with care. The packaging al-

lows for the use of a forklift or pallet jack. Use 

appropriate and safe lifting equipment. 

 •  Store and transport the unit in an upright position.

 •  Store the unit between -35°C and 60°C.

 •  Don’t expose the packaging to rain or corrosive 

atmosphere.

 •  After unpacking, check that the unit is com-

plete and undamaged.

3 – Installation precautions

 Do not braze as long the condensing unit is 

under pressure.

 Never place the unit in a flammable atmosphere 

 Place the unit in such a way that it is not blocking 

or hindering walking areas, doors, windows or similar.

 •  Ensure adequate space around the unit for air 

circulation and to open doors. Refer to picture1 

for minimal values of distance to walls.

 •  Avoid installing the unit in locations which are daily 

exposed to direct sunshine for longer periods.

 •  Avoid installing the unit in aggressive and dus-

ty environments.

 •  Ensure a foundation with horizontal surface 

(less than 3° slope), strong and stable enough 

to carry the entire unit weight and to eliminate 

vibrations and interference.

 •  The unit ambient temperature may not exceed 

52°C during off-cycle.

 •  Ensure that the power supply corresponds to 

the unit characteristics (see nameplate).

 •  When installing units for HFC refrigerants, use 

equipment specifically reserved for HFC refri-

gerants which was never used for CFC or HCFC 

refrigerants.

 •  Use clean and dehydrated refrigeration-grade 

copper tubes and silver alloy brazing material.

 •  Use clean and dehydrated system components.

 •  The suction piping connected to the compres-

sor must be flexible in 3 dimensions to dampen 

vibrations. Furthermore piping has to be done 

in such a way that oil return for the compres-

sor is ensured and the risk of liquid slug over in 

compressor is eliminated.

•  

For all units factory setting of fan speed 

controller to be 15 ±1 bar.

•  For refrigerant R134a, adjust the factory pres-

sure setting of XGE-2C (code no: 061H3144) 

from 15 ±1 bar to recommended setting 8 bar 

by rotating the screw by 9 turns in counter 

clockwise direction.
