[?NIT MAY NOT OPERATE
Failure to follow this caution may result in intermittent unit
operation
Unit must not be installed, operated, and then mined off and
left in an unoccupied structure during cold weather when
temperature drops to 32cT and below unless &ain trap and
drain line have adequate t'reeze protection. See Service and
Maintenance Instructions for winterizing procedure (See Fig
15.)
Step 10--Condensate Drain
GENERAL
( ondensate trap is shipped installed in the blower shelf and factow
connected for UPFLOW applications (ondensate trap must be
RELOCATED for use in DOWNFLOW and HORIZONTAL
applications.
(ondensate trap MUST be used for all applications.
An external trap isnot required when connecting the field drain to
this condensate trap.
34
The field drain connection (condensate trap or drain robe coupling)
is sized for ti2=in. CPV(, li2-in PV(, or 5/g-in. ID robe
connection.
Drain pipe and fittings must confbm_ to ANSI standards and
ASTM D1785, D2466 or D2846. CPVC or PVC cement must
confc_rm to ASTM D2564 or F493. Primer must conform to ASTM
F656. In Canada, use CSA or ULC listed schedule 40 (PVC or
PVC drain pipe, fittings, and cement.
When a condensate pump is required, select a pump which is
approved fbr condensing Nmace applications. To avoid conden=
sate spillage, select a pump with an overflow switch.
Furnace condensate is mildly acidic, typically in the pH range of
3.2 to 4.5. Due to corrosive nature of this condensate, a condensate
pH neutralizing filter may be desired. Check with local authorities
to determine if a pH neutralizer is required.
APPLICATION
The furnace, A/C, and humidifier drains may be combined and
drained together. The AiC &ain must have an external, field=
supplied trap prior to the _ilrnace &ain connection. All &ain
connections (t:urnace, Ai(, or humidifier) must be temlinated into
an open or vented drain as close to the respective equipment as
possible to prevent siphoning of the equipment's drain.
