atmosphere. The proper use of this equipment minimizes the
loss of HFCs.
The 19XR PPS system shown in Fig. 1 consists of a pump-
out unit mounted on a storage tank. The pumpout unit is
offered as a free-standing unit that can be used with chillers
that have an existing storage tank or with chillers that have iso-
lation valves that permit built-in refrigerant storage.
The 19XR PPS systems are factory tested and certified to
the American Society of Mechanical Engineers (ASME) pres-
sure vessel code. The tanks are constructed of certified steel
and are pressure rated at 185 psig (1276 kPa). The PPS storage
tank is equipped with dual relief valves for proper venting per
ASHRAE 15 (American Society of Heating, Refrigerating, and
Air-Conditioning Engineers) guidelines. An automatic level
switch is prewired to the control circuit to ensure proper stor-
age levels.
The 19XR pumpout unit is a complete, hermetic, compact
unit that consists of:
• a hermetic reciprocating 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 pumpout unit and storage tank name-
plates. 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 conveyance. If unit appears dam-
aged, 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 pro-
vided 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.
