b. Equivalent system freeze protection products
may be used in lieu of product referenced above.
In general, freeze protection for new or existing
systems must use specially formulated glycol,
which contains inhibitors, preventing the glycol
from attacking the metallic system components.
Insure that system fluid contains proper glycol
concentration and inhibitor level. The system should
be tested at least once a year and as recommended by
the manufacturer of the glycol solution. Allowance
should be made for expansion of the glycol solution.
WARNING
Poison Hazard. Use only inhibited propylene
glycol solutions specifically formulated for
hydronic systems. Do not use ethylene glycol,
which is toxic and can attack gaskets and seals
used in hydronic systems. Use of ethylene
glycol could result in property damage, personal
injury or death.
E. Condensate Overflow Switch and Condensate
Trap Removal and Replacement:
For removal or replacement of the condensate overflow
switch and/or condensate trap follow the steps below. For
parts identification, refer to Section XIII “Repair Parts”.
1. Condensate Overflow Switch Removal and
Replacement:
a. Disconnect power supply to boiler.
b. Remove 2 wire nuts and disconnect overflow switch
wire pigtails from boiler wiring.
c. Using pliers, release spring clip securing the
overflow switch to condensate trap body and remove
the switch. Note that the switch has factory applied
silicon adhesive seal, which may have to be carefully
cut all around to facilitate the switch removal.
d. Insure the trap overflow switch port is not obstructed
with silicon seal debris, clean as needed.
e. Apply silicon sealant to the replacement switch
threads and install the switch into the trap body
making sure it is properly oriented - the arrow
molded into the switch hex end side must face
down for proper switch operation. See Figure 60
“Condensate Overflow Switch Orientation” for
details.
