The 19XR pumpout unit is a complete, hermetic, compact unit
that consists of:
• a hermetic compressor with a direct-drive motor.
• a water-cooled refrigerant condenser.
• an oil separator.
• suction and discharge valves to control refrigerant flow.
• prewired safety and control devices.
INSTALLATION
Step 1 — Complete Pre-Installation Checks
IDENTIFY UNIT
Identify the assembly number (see Table 1) printed on the pum-
pout unit and storage tank nameplates. Check this information
against the job requirements. Figure 1 shows the PPS system and
its major components. Refer to Tables 2 and 3 for physical data.
INSPECT SHIPMENT
Inspect unit for damage before removing unit from shipping con-
veyance. If unit appears damaged, it should be inspected by a
shipping inspector before removal. File a claim with the shipping
company if shipment is damaged or incomplete. The manufacturer
is not responsible for damage incurred during transit.
Check all components. Notify the supplier immediately if any
item is missing. To prevent loss or damage, leave all parts in their
original package until they are needed.
Step 2 —
Mount the Pumpout Unit
The pumpout unit, if purchased separately, may be mounted
directly on the chiller or it may be floor mounted.
MOUNTING ON THE CHILLER
See instructions provided with the chiller for mounting the
pumpout unit. A typical chiller mount is shown in Fig. 2.
FLOOR MOUNTING
Select a ventilated and accessible area, free of traffic or other
hazards. Remove and discard the 4 angle supports at the base of
the pumpout unit and bolt the unit to the floor through the holes at
the base of the pumpout unit. Special isolation is unnecessary.
Contact surface and dimensions for the pumpout unit are given in
Fig. 3.
