Schreiber Chillers Excellon - Manual (Page 9)

evaporator coil, are standard to the refrigeration industry. The evaporator coil is installed
in a stainless steel tank and the tank on each unit has a large area. This large area
allows better control of water temperature and causes the water flow not to be
restricted, resulting in better water circulation. Any repairs to the refrigeration system
should be done by a qualified refrigeration company. Schreiber Engineering will always
have a service engineer available to answer any questions regarding chiller service.
This unit has a service valve on the suction and discharge line. The suction line has its
valve on the suction line. The high pressure or discharge service line is on the receiver.
This unit is charged with R-22. DO NOT OVERCHARGE because this will cause
damage to the compressor. The refrigeration sight glass is fuzzy until the unit reaches
it's proper temperature.
MAINTAINING THE CHILLER
Very little maintenance is required on this unit. It might be necessary to clean out the
heat exchanger located within the water tank, only depending on the condition of the
water used in the chilled water circuit. It might also be necessary to blow out the
condenser from time to time, depending on the environment of the installed unit. Finally,
the water-cooled condenser needs to be flushed out once in a while. The frequency of
this process depends on the condition of the condenser's water supply.
