Specifications

50 Part Number STH12 9/10
• Inspect air compressor to verify cut-in at 70 psi
(4.8 bar) and cut-out at 90 psi (6.3 bar). Adjust
pressure switch if necessary.
• Inspect system for air leaks and repair as required.
Refrigeration unit
Every 4 months (3 times per year)
• Clean the refrigeration unit air-cooled condenser
using a vacuum cleaner. If equipped with water-
cooled condenser, verify the water discharge
temperature is at 105°F (41°C). Adjust water
modulating valve if necessary.
• Inspect water bath to verify water level is at the top
of stand pipe. If below, add water and repair water
makeup device. If excessive amount of water is
flowing over stand pipe, locate leak within bath and
repair.
• Inspect ice bank within the water bath to verify
proper size ice bank and clarity. Look for uniform,
2" to 4" thick ice bank.
• Drain, clean, and refill water bath.
• Inspect agitator motor and ensure proper
operation.
• Inspect the circulating motor/pump assembly.
Clean strainer and oil motor.
• Inspect the carbonating motor/pump assembly.
Clean strainer and oil motor.
• Inspect entire system for leaks and repair as
required.
Water filters
Every 4 months (3 times per year)
• Verify that incoming water pressure is not less than
40 psi (2.8 bar) or greater than 60 psi (4.1 bar). If
equipped with a water regulator, verify proper
setting of 55 psi (3.8 bar). Adjust if necessary.
• If pressure is low, inspect water filter cartridges to
ensure they are able to supply adequate water
pressure under normal system flow. Replace if
unable to provide minimum 20 psi (1.4 bar) under
load.
