CONDENSER
contains 2 manifolds, each in 2 sections to be field
\-1 welded. Manifolds should not be used where regu-
lating valves are required because separate valves
must be used on each condenser circuit.
Set water regulating valve to maintain designed
head pressure. Do not adjust to compensate for
high head pressures caused by fouled condenser
tubes, excess refrigerant or the presence of non-
condensables. Due to changes in water temperature,
it may be necessary to adjust the valve seasonally.
After adjusting for designed head pressure, shut
unit down. Water regulating valve should shut off
flow of water in a few minutes. If it does not, raise
head pressure setting. Make sure capillary tube
from each water regulating valve is connected to
proper condenser purge valve.
Condenser water must enter at bottom connec-
tions shown in Fig. 1 for proper operation
of internal subcooler located in bottom of
condenser.
On 30HR units, pressure relief valve is on con-
denser side. On 30HS units relief valve is factory
installed in each refrigerant circuit, after the muffler,
and set to relieve at 450 psig. In case of a high pres-
sure cutout failure, valve will open to prevent ex-
cessive pressure buildup in refrigerant circuit. Most

NOTE: For 070, 080 and 090 units, the charge is 2/3 in circuit 1 and
1/3 in
circuit 2. For units 100, 120, 140 & 160, the;charge is half in each circuit.
For unit 110, charge per circuit is listed (cla 1/ckt 2).
local codes require that a relief valve be vented
directly to outdoors.
The vent line must not be
smaller than relief valve outlet.
Provide means for draining system and for ser-
vicing the unit in winter.
On all 30HS units, install a liquid line shutoff
valve between each filter drier and condenser.
