Installation Operation & Maintenance Instructions for the
PuroPak-CP
Step 1: Clean The Closed Loop Hydronic System With Clean 5
Add 1 bottle (500 mL or 16.9 oz.) of AXI-THERM CLEAN 5 for every 100 litres (25 gallons) of
water (Dosage: 0.5 %). Lower concentrations do not yield satisfactory results. Higher concentrations
have no adverse effects.
Use an AXI-THERM INJET, or a mechanical fill pump to add the product to the system. Clean 5
may be circulated in one of two ways: 1) Power Flushing with external high velocity pump (see
Figure 1 ‘A’) or by circulating throughout the entire system using the existing system circulators (see
Fi
gure 1 ‘B’).
When Power Flushing, the heating appliance must be off during the entirety of the cleaning process,
2-
4 hours, (Figure 1 ‘A’). When
Clean 5 is left to circulate through the entire system it is
recommended to shut the heating appliance off only while the solution is being added to the system.
Once cleaner has been administered the system operation may be restored and should be circulated
for at least 2 days and may remain in the system for up to 30 days (Figure 1’B’).
Once the cleaning operation is completed, the system should be well drained and rinsed. Rinsing
should continue until the water runs clear. If the water does not run clean, repeat the cleaning session.

Power flush Clean 5 through existing
system via mechanical pump. Depending on the
severity of encrustrations, power flushing may
require 2-4 hours of run time

Circulate Clean 5 through system via
existing system circulators. Circulate for 2-30 days
before draining and rinsing.
