DESCRIPTION
The PTAC Hydronic Kit is an enclosure kit that provides
complete coverage of all PTAC plumbing and coils while still
allowing access to controls. The kit can only be installed
where there is a central boiler for heating the water. It does
not affect unit heating and cooling operations. The hydronic
kit chassis slides out for service without removing any
hydronic plumbing. The electrical connections are plug-in
type to assist in kit installation.
NOTE: Heat pump models will operate on heat pump
function down to the switchover temperature before operat-
ing on hydronic heat.
Freeze Protection
For PTAC Hydronic Coil freeze protection on hot water
systems, the hydronic system should use an antifreeze

ATTENTION INSTALLING PERSONNEL
As a professional installer you have an obligation to know the product better than the customer. This
includes all safety precautions and related items.
Prior to actual installation, thoroughly familiarize yourself with this Instruction Manual. Pay special attention
to all safety warnings. Often during installation or repair it is possible to place yourself in a position which is
more hazardous than when the unit is in operation.
Remember, it is your responsibility to install the product safely and to know it well enough to be able to
instruct a customer in its safe use.
Safety is a matter of common sense...a matter of thinking before acting. Most dealers have a list of specific
good safety practices...follow them.
The precautions listed in this Installation Manual are intended as supplemental to existing practices.
However, if there is a direct conflict between existing practices and the content of this manual, the
precautions listed here take precedence.
RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION.
solution. However, the addition of antifreeze will reduce the
capacity of the hydronic coil and affect system sizing. The
higher the antifreeze concentration, the greater the capacity
reduction.Therefore,foroptimumunitperformance,onlyuse
an antifreeze concentration that will protect to the lowest
ambient temperature expected. A 20% solution will protect
to approximately 15°F. A 50% solution protect to -35°F.
Use an antifreeze that is formulated for hydronic use. DO

JOB PREPARATION
Before installing the hydronic kit, determine the following:
• Whether a 2-way or 3-way normally open or normally
closed valve is required.
• If an end switch is required to control the circulating
pump. (Information relating to U.L. approved valves
and current loads is shown on the kit label and is
repeated in the following figure).
NOTE: WHEN HYDRONIC HEAT IS USED, DISREGARD THE MINIMUM CIRCUIT AMPACITY AND MAXIMUM
FUSE SIZE SHOWN ON THE AUXILIARY NAMEPLATE FOR FIELD INSTALLED HEATERS. USE VALVES
SHOWN ON THE MASTER UNIT NAMEPLATE.
CAUTION: VOLTAGE RATING OF VALVE IS 24VAC AND DOES NOT CORRESPOND TO
VOLTAGE RATING ON THE UNIT NAMEPLATE.
THIS KIT MAY BE USED WITH ONE OF THE
FOLLOWING ELECTRIC CONTROL VALVES:

Also, ensure that the following steps are completed and a
hydronic model chassis is installed before installation.
NOTE: The hydronic chassis MUST have a model
number in which the 10th, 11th, 12th or 13th digit
is H.
1. Wall sleeve is installed and completely sealed.
It must extend at least 3” and no more than 3-1/8” past
the finished interior wall in order to properly install the
hydronic kit.
2. All plumbing stub-outs are completed.
3. Unit chassis is uncrated, uninstalled, and not yet
connected to an electrical source.
INSTALLATION
The installation and servicing of the equipment re-
ferred to in this booklet should be performed by quali-
fied, experienced technicians.
Be sure to engage the services of a qualified water
treatment specialist to determine what water treat-
ment, if any, is needed. The manufacturer will not
assume responsibility for equipment failures resulting
from untreated or improperly treated water.

as shown (Figure 1).
NOTE: If there is not enough room to drill holes from the
side then drill holes from inside the wall sleeve.

2. Remove the hydronic kit from its packaging. Recycle the
cardboard packaging material.
3. Mount the two support brackets to the bottom of the
hydronic top (Figure 2) with four (4) 3/8-inch #8 supplied
screws.
On HVK03E Hydronic Steam Kits, do not use 1/4 inch head,
3/8 inch long, #8 screws to attach the left support bracket
to the hydronic top. Use the provided two 5/16 inch painted
head, 1/4 inch long, #8 screws in place of these longer
screws. (Figure 3)
NOTE: Failure to use the 1/4 inch long screws instead
of the 3/8 inch long screws may result in leaks of the
hydronic steam coil.

6. Place the chassis back into the wall sleeve and secure
chassis to wall sleeve.
7. Measure the actual distance “D” (Figure 6) from the
bottom of the chassis basepan to the finished floor to
determine how far to extend the skirt below the metal
front. If the distance is less than two inches, trim the
skirt per Figure 7 so that it will not interfere with the
gasket or block the inlet air on the front. In Figure 7, “Y”
dimension equals 2” minus actual “D” dimension.

For normally open valves, connect the YL chassis
harness wire to the second BK wire from the valve.
For normally closed valves, connect the BL chassis

TWO-WAY VALVE INSTALLATION
Wheninstalling two-wayvalves,theflow direction isfromend
“B” as shown in Figure 15.
Prior to soldering the normally closed two-way valve, open
the ports by slowly moving the manual operating lever to the
retaining notch until lever is secured by valve spring. The
lever will reset to the automatic position the first time the
valve is energized.
THREE-WAY VALVE INSTALLATION
When installing three-way diverting valves, end “B” is the
supply to coil and end “A” is the bypass end. The inlet port
is unmarked. Port markings “A” and “B” are located on the
bottom of the valve body (Figure 15).
