Raypak VERSA 155C, Operating And Installation Instructions

FLOW RATES

MIN GPM   20
MAX GPM 115*
*When flow rates exceed 115  GPM an external auxil-
iary bypass valve is required.  See external auxiliary
bypass valve section for details.

COMPANION FLANGE CONNECTIONS

DO NOT 

use petroleum base assembly fluids

(such as Petroleum Jelly or lubricating oil).  If assembly
lubrication is required use a silicone base such as
Amoral etc.

The inlet/outlet single header flanges are designed

for four type of water connections.  There are two sets
of flange gaskets supplied with your header; one set
installed, between flanges and in/out header, and the
other set shipped loose in the unit.  Use the appropriate
gasket design, for all your heater connections.

GASKET DESIGN #1

: (Factory installed) Accepts

1-1/2" copper tube or 1-1/4" galvanized pipe as a slip
connections.

GASKET DESIGN #2

: (Loose In a bag) Accepts 2"

copper tube as a slip connection.  The flange is
threaded for 2" screw in pipe connections.  Also used
with the 2" CPVC adapters.

PLUMBING  FOR  WATER  CONNECTIONS

LOCATION

The VERSA heater requires water flow and posi-

tive pressure to fire and operate properly. It must
therefore be installed downstream of the discharge
side of the filter pump. A typical installation is plumbed
as follows:

1. The inlet side of the filter is plumbed directly

 to the discharge side of the filter pump;

2. The outlet side of the filter is then plumbed

to the inlet of the heater; and

3. The outlet of the heater is plumbed to the

 return line to the pool or spa. The pump,
filter and heater are thus plumbed in series.

Plumbing from the heater back to the pool must not

have any valves or restriction that could prevent flow
when the pump is operating. To do so will void the
warranty

Heater must be located so that any water leaks will

not damage the structure of adjacent area.  High
temperature 2" plastic pipe (CPVC) may be threaded
directly into the header flanges.  This is not the same as
the Schedule 80 PVC pipe which is also colored gray.
PVC may be used immediately after the CPVC adapt-
ers

2" CPVC Adapters

INLET OUTLET HEADER

CAUTION: 

NEVER install PVC directly into header

flanges.  Use the 2" CPVC adapter supplied loose with
the heater.
