INTRODUCTION
Which type of booster heater do I have?
PrecisionTemp manufactures two booster heater models.
1. The PT-56 is used for all single rack door-type dishmachines. This unit is ETL certified
for ventless operation (check local codes as some states do not allow ventless gas
appliances) and has an internal tank and pump.
2.
The PT-200 is used for all conveyor and flight type dishmachines. This unit requires a
flue be fitted. This flue can exit into the pant leg duct or exhaust / condensate hood over
the dishmachine (check local codes). There are three types of PT-200:
a. PT-200FT-199,000BTU flow through design where the booster is located close to
the dishmachine, typically under the dish table. Rinse flow rate 4-5+gpm.
NOTE: The NSF-5 Code requires that booster heaters be located within five pipe
feet of the dishmachine to maintain proper rinse temperature. If this cannot be
accomplished, the pipe must be insulated or a recirculation system be installed.
b. PT-200OR-125,000BTU same as the PT-200FT, it is used for newer low flow
water conserving dishmachines. Rinse flow rate 2-3gpm. For service issues, use
the PT-200FT installation, operation, and service instructions
c. PT-200RC- recirculation design, where the booster heater is located far from the
dishmachine. An additional pump and storage tank are fitted to the water lines to
the dishmachine, external to the booster heater.
3. Aside from the model number, you can verify which model you have by looking at the
model number label located on the front panel of the booster heater.
IMPORTANT! Verify which software version you have before completing any service!
You can verify this by looking at the software version label on the green electronic board
inside the electronic drawer. When using this service manual, ensure you are using the
correct software version. Check the software version label on the microprocessor with the list
