Step 2 — Check Compressor Mounting —
As
shipped, each compressor is held down by 4 bolts. After unit is
installed, verify mounting bolt torque 12 to14 ft-lb.
Step 3 — Cooler Fluid and Drain Piping Con-
nections (Units Without Hydronic Packages) —
These chillers are supplied with factory-installed strainer
(including blow-down valve) in the entering fluid piping and
flow switch in the leaving fluid piping. Flow switch wiring is
factory installed.
Piping connections are located on the left side of the chiller
when facing the control panel for 010-030 sizes and at the end
opposite the control panel for 032-055 sizes. See Fig. 4-9
depending on model.
All sizes have FPT connections as shown in the Physical
Data tables. Provide a means of venting air from the high point
of the field-installed piping as required. Install field-supplied
drains in both the entering and leaving fluid connections.
After field piping is complete, freeze-up protection is rec-
ommended using inhibited ethylene glycol or other suitable in-
hibited antifreeze solution and electric heat tapes in areas
where piping is exposed to low ambient temperatures (34 F
[1 °C] or below). Heat tapes should possess a rating for area
ambients and be covered with a suitable thickness of closed-
cell insulation. Route power for heating tapes from a separately
fused disconnect. Identify disconnect as heat tape power source
with a warning that power must not be turned off except when
unit is being serviced.
The cooler drain connection is at the opposite end from the
compressor (see Fig. 4-9). Insulate the drain piping (in the
same manner as the chilled water piping) for at least one ft
(305 mm) from cooler.
PREPARATION FOR YEAR-ROUND OPERATION — If
unit is in operation year-round, add sufficient inhibited ethyl-
ene glycol or other suitable inhibited antifreeze solution to
chilled water to prevent freezing under low-ambient operating
conditions. Consult local water treatment specialist on charac-
teristics of water and recommended inhibitor.
PREPARATION FOR WINTER SHUTDOWN — Do not
shut off electrical disconnect during off-season shutdown. At
end of cooling season:
1. Position LOCAL/OFF/REMOTE switch to OFF.
2. Drain water from system.
3. Replace drain plug and put 2 gallons (8 liters) of inhibited
ethylene glycol (or other suitable inhibited anti-freeze) in
cooler to prevent freezing of residual water.
4. At the beginning of the next cooling season, refill cooler
and add recommended inhibitor.
